Le noyau en fer est constitu\u00e9 de t\u00f4les d'acier au silicium de haute qualit\u00e9 et hautement performantes, pr\u00e9sentant une perm\u00e9abilit\u00e9 magn\u00e9tique \u00e9lev\u00e9e, ce qui se traduit par de faibles pertes \u00e0 vide.<\/p><p>2. Les enroulements haute tension adoptent tous une structure cylindrique multicouche afin d'am\u00e9liorer la r\u00e9partition des impulsions de tension au sein des enroulements. Les enroulements basse tension, dont la plage de puissance s'\u00e9tend de 30 kVA \u00e0 4 000 kVA, pr\u00e9sentent une structure cylindrique ou en spirale. Ils se caract\u00e9risent par une r\u00e9sistance m\u00e9canique \u00e9lev\u00e9e, une r\u00e9partition \u00e9quilibr\u00e9e des amp\u00e8res-tours et une forte r\u00e9sistance aux courts-circuits.<\/p><p>3. Une structure fixe est install\u00e9e \u00e0 l'int\u00e9rieur du transformateur afin d'emp\u00eacher tout d\u00e9placement pendant le transport. Toutes les fixations sont \u00e9quip\u00e9es d'\u00e9crous de blocage afin de garantir qu'elles ne se desserrent pas lors d'un fonctionnement \u00e0 long terme.<\/p><p>4. Ce produit pr\u00e9sente une structure enti\u00e8rement herm\u00e9tique. Lors du conditionnement, un proc\u00e9d\u00e9 de remplissage d'huile sous vide est utilis\u00e9 afin d'\u00e9liminer compl\u00e8tement l'humidit\u00e9 du transformateur, garantissant ainsi l'isolation entre l'huile du transformateur et l'air ext\u00e9rieur, emp\u00eachant le vieillissement de l'huile et am\u00e9liorant la fiabilit\u00e9 de fonctionnement du transformateur.<\/p><p>5. Le produit est \u00e9quip\u00e9 d'une soupape de surpression, d'un thermom\u00e8tre indicateur, d'un relais de gaz, etc., afin de garantir le fonctionnement en toute s\u00e9curit\u00e9 du transformateur.<\/p><p>6. Ce produit est \u00e9quip\u00e9 d'un r\u00e9servoir d'huile ondul\u00e9. Ce type de r\u00e9servoir est simple \u00e0 fabriquer, pr\u00e9sente une r\u00e9sistance m\u00e9canique \u00e9lev\u00e9e, permet d'obtenir de bons r\u00e9sultats de soudage et est \u00e9tanche. De plus, gr\u00e2ce \u00e0 la grande fluidit\u00e9 de l'huile, la capacit\u00e9 de dissipation thermique du produit est am\u00e9lior\u00e9e.<\/p><p>7.

Efficacit\u00e9 \u00e9lev\u00e9e de dissipation thermique, adapt\u00e9e aux applications \u00e0 forte puissance. La conductivit\u00e9 thermique de l'huile isolante (huile min\u00e9rale ou synth\u00e9tique) est bien sup\u00e9rieure \u00e0 celle de l'air (principal milieu de dissipation thermique des transformateurs de type sec). De plus, la chaleur provenant des enroulements et des noyaux de fer peut \u00eatre rapidement \u00e9vacu\u00e9e gr\u00e2ce \u00e0 la convection naturelle de l'huile ou \u00e0 une circulation forc\u00e9e (par exemple, en ajoutant des pompes \u00e0 huile et des radiateurs).<\/p><p>2. Excellentes performances d'isolation et forte r\u00e9sistance \u00e0 la haute tension. L'intensit\u00e9 de champ de claquage de l'huile isolante (environ 25 \u00e0 35 kV\/mm) est sup\u00e9rieure \u00e0 celle de l'air (environ 3 kV\/mm), ce qui permet d'assurer une protection isolante plus fiable en cas de haute tension.<\/p><p>3. Faible co\u00fbt et excellent rapport qualit\u00e9-prix. Le co\u00fbt des mati\u00e8res premi\u00e8res de l'huile isolante est inf\u00e9rieur \u00e0 celui des mat\u00e9riaux isolants tels que la r\u00e9sine \u00e9poxy et le papier Nomex utilis\u00e9s dans les transformateurs de type sec. De plus, le processus de fabrication des transformateurs \u00e0 huile (notamment l'encapsulation du noyau de fer et des enroulements) est relativement simple, ce qui se traduit par des co\u00fbts de production et de fabrication moins \u00e9lev\u00e9s.<\/p><p>4. Cycle d'entretien prolong\u00e9 et bonne r\u00e9sistance aux intemp\u00e9ries. L'huile isolante exerce un effet d'\u00e9tanch\u00e9it\u00e9 et de protection, ce qui permet d'isoler les enroulements et les noyaux de fer de l'\u00e9rosion caus\u00e9e par l'humidit\u00e9 et la poussi\u00e8re pr\u00e9sentes dans l'air, et de r\u00e9duire le taux de vieillissement oxydatif. L'entretien quotidien consiste principalement \u00e0 contr\u00f4ler r\u00e9guli\u00e8rement la qualit\u00e9 de l'huile (notamment les pertes di\u00e9lectriques et la teneur en eau) et \u00e0 remplacer l'huile isolante, selon un cycle g\u00e9n\u00e9ralement compris entre 1 et 3 ans. Lorsqu\u2019il est install\u00e9 \u00e0 l\u2019ext\u00e9rieur, le r\u00e9servoir d\u2019huile ferm\u00e9 du transformateur \u00e0 immersion d\u2019huile r\u00e9siste aux al\u00e9as climatiques tels que la pluie, la neige et les temp\u00e9ratures \u00e9lev\u00e9es, ce qui le rend adapt\u00e9 aux installations en plein air dans les zones rurales et les banlieues.<\/p><p>5. Forte capacit\u00e9 de surcharge. L'huile isolante poss\u00e8de une grande capacit\u00e9 thermique. En cas de surcharge de courte dur\u00e9e (par exemple pendant les pics de consommation \u00e9lectrique), la temp\u00e9rature de l'huile augmente lentement, ce qui lui permet de supporter des charges sup\u00e9rieures \u00e0 la capacit\u00e9 nominale pendant un certain temps.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div id=\"e-n-tab-content-649863463\" role=\"tabpanel\" aria-labelledby=\"e-n-tab-title-649863463\" data-tab-index=\"3\" style=\"--n-tabs-title-order: 3;\" class=\"elementor-element elementor-element-764f307 e-con-full e-flex e-con e-child\" data-id=\"764f307\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-9872304 elementor-widget elementor-widget-heading\" data-id=\"9872304\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Structure du produit<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b1b2cc5 elementor-widget elementor-widget-text-editor\" data-id=\"b1b2cc5\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Les processus cl\u00e9s peuvent \u00eatre divis\u00e9s en cinq \u00e9tapes principales : la fabrication des composants principaux, l'assemblage final, le traitement d'isolation, le remplissage d'huile et le traitement sous vide, ainsi que les essais et contr\u00f4les.

Cela s'explique par le fait que les temp\u00e9ratures \u00e9lev\u00e9es r\u00e9duisent la viscosit\u00e9 de l'huile, ce qui affaiblit sa fluidit\u00e9 et diminue ainsi l'efficacit\u00e9 de la dissipation thermique par convection naturelle. \u00c0 ce stade, la temp\u00e9rature des enroulements du transformateur augmente rapidement, ce qui acc\u00e9l\u00e8re le vieillissement de l\u2019isolation. Selon la loi d\u2019Arrhenius, la dur\u00e9e de vie de l\u2019isolation est r\u00e9duite de moiti\u00e9 pour chaque augmentation de temp\u00e9rature de 8 \u00b0C.

Il peut s\u2019av\u00e9rer n\u00e9cessaire de r\u00e9duire la puissance nominale du transformateur ; dans le cas contraire, il existe des risques de d\u00e9t\u00e9rioration de l\u2019isolation et d\u2019incendie.<\/p><p><strong>\u00b7<\/strong><strong>Syst\u00e8me de refroidissement ONAF :<\/strong> Dans les environnements \u00e0 haute temp\u00e9rature, l'efficacit\u00e9 de refroidissement des ventilateurs du syst\u00e8me ONAF diminue. Bien que la dissipation thermique puisse \u00eatre am\u00e9lior\u00e9e par l'ajout d'\u00e9quipements de refroidissement auxiliaires, les performances globales s'en trouvent tout de m\u00eame affect\u00e9es dans une certaine mesure. Toutefois, par rapport au syst\u00e8me de refroidissement ONAN, le syst\u00e8me ONAF, gr\u00e2ce \u00e0 la dissipation active de la chaleur par les ventilateurs, offre un meilleur rendement de dissipation thermique dans les m\u00eames conditions de temp\u00e9rature \u00e9lev\u00e9e.

oil-immersed transformers in our company can be divided into four categories based on the test stage and purpose: factory tests, type tests, on-site tests, and preventive tests.<\\\/p><p><strong>1.<\\\/strong><strong>Factory Tests (Verification Tests During Manufacturing)<\\\/strong><\\\/p><p>They mainly include: insulation resistance measurement, DC resistance measurement, turns ratio measurement, connection group and polarity test, no-load test, insulating oil test, and sealing test.<\\\/p><p><strong>2<\\\/strong><strong>.Type Tests (Design Verification Tests)<\\\/strong><\\\/p><p>They mainly include: temperature rise test, insulation strength test, short-circuit withstand capability test, zero-sequence impedance test, sound level measurement, tank mechanical strength test, and no-load current harmonic measurement.<\\\/p><p><strong>3.<\\\/strong><strong>On-Site Tests (Acceptance Tests After Installation)<\\\/strong><\\\/p><p>They mainly include: appearance inspection, DC resistance measurement, recheck of turns ratio and connection group, insulating oil breakdown voltage and dielectric loss test, power frequency withstand voltage test (partial), and tap changer operation test.<\\\/p><p><strong>4<\\\/strong><strong>.Preventive Tests (Maintenance Tests During Operation)<\\\/strong><\\\/p><p>They mainly include: insulation resistance and polarization index measurement, winding DC resistance measurement, dielectric loss factor (tan\\u03b4) measurement, insulating oil test, partial discharge measurement, iron core grounding current measurement, bushing test, and infrared thermal imaging detection.<\\\/p><p>The test types for oil-immersed transformers cover the entire life cycle from manufacturing, installation to operation and maintenance. The test focuses at different stages vary: factory tests ensure qualified basic performance, type tests verify design limits, on-site tests guarantee installation quality, and preventive tests prevent operational failures. These tests together form an important guarantee for the safe and reliable operation of transformers.<\\\/p><p><strong>\\u2163<\\\/strong><strong>.<\\\/strong><strong>Component inspection of oil-immersed transformer<\\\/strong><\\\/p><p>Component inspection of oil-immersed transformers is a crucial link to ensure their safe and stable operation, which mainly includes the following contents:<\\\/p><p><strong>1.<\\\/strong><strong>Appearance Inspection:<\\\/strong> Check whether the transformer's appearance is intact, whether there is oil leakage in the oil tank, and whether parts such as junction boxes, insulating bushings, and leads are damaged, rusted, or loose. At the same time, confirm that components like radiators, oil conservators, breathers, and oil level indicators are in normal condition.<\\\/p><p><strong>2.<\\\/strong><strong>Insulation Inspection:<\\\/strong> Use an insulation resistance tester to measure the insulation resistance between windings and ground as well as between windings themselves; the measured values should meet the specified standards. Additionally, conduct dielectric strength tests and insulating oil polarization tests to evaluate insulation performance.<\\\/p><p><strong>3.<\\\/strong><strong>Mechanical Operation Inspection:<\\\/strong> Check whether core equipment such as fans, coolers, pressure relief valves, and voltage regulating valves are operating normally. Ensure that bushings, connecting bolts, and terminal blocks are not loose, so as to guarantee the normal operation of mechanical components.<\\\/p><p><strong>4.<\\\/strong><strong>Oil Quality Inspection:<\\\/strong> Observe the color, odor, and transparency of transformer oil, and check for the presence of mixed impurities. Conduct tower-type oil sampling to inspect sediments and contaminants. Moreover, perform tests on transformer oil such as breakdown voltage, acid value, dielectric loss factor, moisture content, and particle size to determine if the oil quality is good.<\\\/p><p><strong>5.<\\\/strong><strong>Partial Discharge Detection:<\\\/strong> Use partial discharge detectors, such as installing UHF sensors or using high-frequency current transformers and ultrasonic sensors, to detect parts of the transformer such as windings and insulating bushings, and locate the position of the discharge source. If the partial discharge amount exceeds the specified value, the insulation risk needs to be evaluated.<\\\/p><p><strong>6.<\\\/strong><strong>Oil Temperature Inspection:<\\\/strong> Check whether the on-site gauge indications of the transformer's upper-layer oil temperature and high\\\/low winding temperatures are consistent with the readings on the control panel or CRT display. Verify if all temperatures are normal and whether they are close to or exceed the maximum allowable limits. At the same time, touch the surface of the radiating pipes by hand to check if the cooling device is in good condition.<\\\/p><p><strong>7.<\\\/strong><strong>Voltage and Current Inspection:<\\\/strong> Measure whether the voltage and current on the high-voltage side and low-voltage side of the transformer are within the normal range. Generally, the voltage on the high-voltage side must not exceed 105% of the nominal voltage value of its corresponding tap, to ensure the transformer operates within rated parameters.<\\\/p><p><strong>8.<\\\/strong><strong>Sound Inspection:<\\\/strong> A normally operating transformer emits a uniform \\\"buzzing\\\" sound. During inspection, pay attention to the presence of abnormal sounds such as sharp noises or crackling sounds. Abnormal sounds may be caused by internal faults or looseness and other reasons.<\\\/p><p><strong>\\u2164<\\\/strong><strong>.<\\\/strong><strong>Certificate: <\\\/strong>CE, UL, ISO, SGS, CCC<\\\/p>\",\"paragraph_spacing\":{\"unit\":\"px\",\"size\":16,\"sizes\":[]},\"_padding\":{\"unit\":\"px\",\"top\":\"20\",\"right\":\"0\",\"bottom\":\"0\",\"left\":\"0\",\"isLinked\":false},\"__globals__\":{\"typography_typography\":\"globals\\\/typography?id=d06f507\"}},\"elements\":[],\"widgetType\":\"text-editor\"}],\"isInner\":true,\"isLocked\":true},{\"id\":\"2e2154e\",\"elType\":\"container\",\"settings\":{\"_title\":\"Tab #2\",\"content_width\":\"full\",\"border_border\":\"solid\",\"border_width\":{\"unit\":\"px\",\"top\":\"1\",\"right\":\"1\",\"bottom\":\"1\",\"left\":\"1\",\"isLinked\":true},\"padding\":{\"unit\":\"px\",\"top\":\"50\",\"right\":\"30\",\"bottom\":\"50\",\"left\":\"30\",\"isLinked\":false},\"__globals__\":{\"border_color\":\"globals\\\/colors?id=secondary\"},\"padding_mobile\":{\"unit\":\"px\",\"top\":\"10\",\"right\":\"10\",\"bottom\":\"10\",\"left\":\"10\",\"isLinked\":true}},\"elements\":[{\"id\":\"0f27574\",\"elType\":\"widget\",\"settings\":{\"title\":\"Structural Features\",\"__globals__\":{\"typography_typography\":\"globals\\\/typography?id=204d764\"}},\"elements\":[],\"widgetType\":\"heading\"},{\"id\":\"f30b232\",\"elType\":\"widget\",\"settings\":{\"editor\":\"<p><strong>\\u2160.<\\\/strong><strong>Product features<\\\/strong><\\\/p><p>1.The iron core is made of high-quality, high-performance silicon steel sheets with high magnetic permeability, resulting in low no-load loss.<\\\/p><p>2.The high-voltage windings all adopt a multi-layer cylindrical structure to improve the voltage impulse distribution of the windings. The low-voltage windings, with a capacity range of 30KVA to 4000KVA, use a cylindrical or spiral structure. They feature high mechanical strength, balanced ampere-turn distribution, and strong short-circuit resistance.<\\\/p><p>3.A fixed structure is installed inside the transformer to prevent displacement during transportation. All fasteners are equipped with locking nuts to ensure they do not loosen during long-term operation.<\\\/p><p>4.This product has a fully sealed structure. During packaging, a vacuum oil-filling process is adopted to completely remove moisture from the transformer, ensuring isolation between transformer oil and external air, preventing oil aging, and improving the operational reliability of the transformer.<\\\/p><p>5.The product is equipped with a pressure relief valve, a signal thermometer, a gas relay, etc., to ensure the safe operation of the transformer.<\\\/p><p>6.This product uses a corrugated oil tank. Such a tank is simple to process, has high mechanical strength, achieves good welding results, and is leak-proof. Moreover, due to the strong fluidity of the oil, the heat dissipation capacity of the product is enhanced.<\\\/p><p>7.The surface of the oil-immersed power transformer is treated with degreasing, derusting, and phosphating, followed by the application of primer and topcoat.<\\\/p><p>8.This product can meet the special operational requirements of industries such as metallurgy and petrochemicals, as well as the special operational needs of humid and dirty environments.<\\\/p><p><strong>\\u2161<\\\/strong><strong>.<\\\/strong><strong>Product <\\\/strong><strong>Advantages<\\\/strong><\\\/p><p>1.High heat dissipation efficiency, suitable for large - capacity scenarios. The thermal conductivity of insulating oil (mineral oil or synthetic oil) is far superior to that of air (the main heat dissipation medium of dry - type transformers). Moreover, the heat from windings and iron cores can be quickly taken away through the natural convection of oil or forced circulation (such as adding oil pumps and radiators).<\\\/p><p>2.Excellent insulation performance and strong high-voltage resistance. The breakdown field strength of insulating oil (about 25 - 35kV\\\/mm) is higher than that of air (about 3kV\\\/mm), which can provide more reliable insulation protection under high voltage.<\\\/p><p>3.Low cost and high cost - performance ratio. The raw material cost of insulating oil is lower than that of insulating materials such as epoxy resin and Nomex paper used in dry - type transformers. In addition, the structural process of oil - immersed transformers (such as iron core and winding encapsulation) is relatively simple, resulting in lower production and manufacturing costs.<\\\/p><p>4.Long maintenance cycle and good weather resistance. Insulating oil has a sealing and protective effect, which can isolate the erosion of moisture and dust in the air on windings and iron cores, and reduce the rate of oxidative aging. Daily maintenance mainly involves regular detection of oil quality (such as dielectric loss and water content) and replacement of insulating oil, with a cycle usually of 1 - 3 years. When installed outdoors, the closed oil tank of the oil - immersed transformer can resist the impact of natural environments such as rain, snow and high temperature, making it suitable for open - air scenarios in rural areas and suburbs.<\\\/p><p>5.Strong overload capacity. Insulating oil has a large heat capacity. During short - term overload (such as during peak electricity consumption periods), the oil temperature rises slowly, and it can bear loads exceeding the rated capacity for a certain period of time.<\\\/p>\",\"_padding\":{\"unit\":\"px\",\"top\":\"20\",\"right\":\"0\",\"bottom\":\"0\",\"left\":\"0\",\"isLinked\":false},\"__globals__\":{\"typography_typography\":\"globals\\\/typography?id=d06f507\"}},\"elements\":[],\"widgetType\":\"text-editor\"}],\"isInner\":true,\"isLocked\":true},{\"id\":\"764f307\",\"elType\":\"container\",\"settings\":{\"_title\":\"Tab #3\",\"content_width\":\"full\",\"padding\":{\"unit\":\"px\",\"top\":\"50\",\"right\":\"30\",\"bottom\":\"50\",\"left\":\"30\",\"isLinked\":false},\"border_border\":\"solid\",\"border_width\":{\"unit\":\"px\",\"top\":\"1\",\"right\":\"1\",\"bottom\":\"1\",\"left\":\"1\",\"isLinked\":true},\"__globals__\":{\"border_color\":\"globals\\\/colors?id=secondary\"},\"padding_mobile\":{\"unit\":\"px\",\"top\":\"10\",\"right\":\"10\",\"bottom\":\"10\",\"left\":\"10\",\"isLinked\":true}},\"elements\":[{\"id\":\"9872304\",\"elType\":\"widget\",\"settings\":{\"title\":\"Product structure\",\"__globals__\":{\"typography_typography\":\"globals\\\/typography?id=204d764\"}},\"elements\":[],\"widgetType\":\"heading\"},{\"id\":\"b1b2cc5\",\"elType\":\"widget\",\"settings\":{\"editor\":\"<p>The core processes can be divided into five major stages: core component manufacturing, final assembly, insulation treatment, oil filling and vacuum treatment, and test detection.

This is because high temperatures reduce the viscosity of the oil, weakening its fluidity and thus lowering the efficiency of natural convection heat dissipation. At this point, the winding temperature of the transformer rises rapidly, accelerating insulation aging. According to the Arrhenius law, the insulation life is halved for every 8\\u00b0C increase in temperature. Meanwhile, high temperatures cause a decrease in the magnetic permeability of silicon steel sheets and an increase in eddy current losses, reducing energy efficiency. The transformer may need to be derated; otherwise, there are risks of insulation damage and fire.<\\\/p><p><strong>\\u00b7<\\\/strong><strong>ONAF Cooling System:<\\\/strong> In high-temperature environments, the cooling effect of the fans in the ONAF cooling system diminishes. Although heat dissipation can be enhanced by adding auxiliary cooling equipment, the overall performance is still affected to a certain extent. However, compared to the ONAN cooling system, the ONAF system, with active heat dissipation by fans, achieves higher heat dissipation efficiency under the same high-temperature conditions.

This may cause heat dissipation to stagnate, or even result in oil solidification (the pour point of transformer oil is approximately -45\\u00b0C). In addition, dissolved water in the oil may turn into suspended ice crystals, increasing the risk of partial discharge. During cold startup, mechanical stress may cause welds or insulation to crack due to brittleness. Therefore, in extremely low temperatures, preheating to above 0\\u00b0C is required before commissioning.<\\\/p><p><strong>\\u00b7<\\\/strong><strong>ONAF Cooling System:<\\\/strong> In low-temperature environments, apart from the issue of increased oil viscosity similar to that of ONAN, the ONAF cooling system also faces the risk of fan icing.

Specifically, it can be comprehensively judged from the following 5 key dimensions:<\\\/p><p><strong>\\u2460<\\\/strong><strong>Transformer Rated Capacity and Heat Generation from Losses<\\\/strong><\\\/p><p>This is the most fundamental basis. The heat generated by a transformer mainly comes from copper losses (load losses) and iron losses (no-load losses).

Heat can be dissipated through the natural convection of transformer oil (hot oil rises, cold oil falls) and the natural convection between the casing\\\/radiator and air, without the need for additional cooling equipment. Therefore, ONAN is preferred.<\\\/p><p><strong>\\u00b7<\\\/strong><strong>Medium and large-capacity transformers (high loss):<\\\/strong><\\\/p><p>When the capacity exceeds the above range (e.g., \\u2265800kVA for 10kV class, \\u22651600kVA for 35kV class), losses increase significantly, and the natural heat dissipation rate cannot match the heat generation. This may cause the oil temperature to exceed national standard limits (usually top oil temperature rise \\u226455K or 60K). In such cases, fans must be used to force air flow and accelerate heat dissipation, so ONAF is chosen.<\\\/p><p>\\u2461<strong>Operating Load Characteristics<\\\/strong><\\\/p><p>The actual load rate and operation mode of the transformer directly affect heat dissipation requirements:<\\\/p><p><strong>\\u00b7<\\\/strong><strong>Low load rate or intermittent operation:<\\\/strong><\\\/p><p>If the transformer operates at light load for a long time (load rate &lt; 50%) or only runs during short-term peak periods (e.g., rural distribution transformers), even if its capacity is slightly larger, the actual heat generation is low. The natural heat dissipation capacity of ONAN can meet the demand, and there is no need to waste energy on fans. Thus, ONAN is selected.<\\\/p><p><strong>\\u00b7<\\\/strong><strong>High load rate or continuous full-load operation:<\\\/strong><\\\/p><p>For transformers in industrial parks, urban core distribution networks, and other equipment that operate at full load for a long time or have large load fluctuations (needing to cope with short-term overload), heat generation remains high. ONAN cannot meet the heat dissipation requirements, so ONAF's forced air cooling via fans is necessary. Even during overload, fans can enhance heat dissipation capacity (usually supporting 10%-20% short-term overload). Hence, ONAF is chosen.<\\\/p><p><strong>\\u2462<\\\/strong><strong>Installation Environment and Heat Dissipation Conditions<\\\/strong><\\\/p><p>Environmental factors directly affect the efficiency of natural heat dissipation, and cooling methods need to be adjusted according to scenarios:<\\\/p><p><strong>\\u00b7<\\\/strong><strong>Well-ventilated and low-temperature environments:<\\\/strong><\\\/p><p>If the transformer is installed in an open outdoor area, high-altitude regions (low air density but good ventilation), or cold areas, the efficiency of natural convection heat dissipation is high.

Even with a slightly smaller capacity, oil temperature may rise excessively due to poor heat dissipation conditions. In such cases, upgrading to ONAF is necessary to compensate for environmental defects through forced air flow by fans.<\\\/p><p>\\u2463<strong>Cost and Maintenance Requirements<\\\/strong><\\\/p><p>There are significant differences in initial costs and operation\\\/maintenance costs between the two cooling methods:<\\\/p><p><strong>\\u00b7<\\\/strong><strong>Advantages of ONAN:<\\\/strong><\\\/p><p>It has no fans or control circuits, resulting in a simpler structure.

oil-immersed transformer<\/strong><\/p><p>The tests for oil-immersed transformers in our company can be divided into four categories based on the test stage and purpose: factory tests, type tests, on-site tests, and preventive tests.<\/p><p><strong>1.<\/strong><strong>Factory Tests (Verification Tests During Manufacturing)<\/strong><\/p><p>They mainly include: insulation resistance measurement, DC resistance measurement, turns ratio measurement, connection group and polarity test, no-load test, insulating oil test, and sealing test.<\/p><p><strong>2<\/strong><strong>.Type Tests (Design Verification Tests)<\/strong><\/p><p>They mainly include: temperature rise test, insulation strength test, short-circuit withstand capability test, zero-sequence impedance test, sound level measurement, tank mechanical strength test, and no-load current harmonic measurement.<\/p><p><strong>3.<\/strong><strong>On-Site Tests (Acceptance Tests After Installation)<\/strong><\/p><p>They mainly include: appearance inspection, DC resistance measurement, recheck of turns ratio and connection group, insulating oil breakdown voltage and dielectric loss test, power frequency withstand voltage test (partial), and tap changer operation test.<\/p><p><strong>4<\/strong><strong>.Preventive Tests (Maintenance Tests During Operation)<\/strong><\/p><p>They mainly include: insulation resistance and polarization index measurement, winding DC resistance measurement, dielectric loss factor (tan\u03b4) measurement, insulating oil test, partial discharge measurement, iron core grounding current measurement, bushing test, and infrared thermal imaging detection.<\/p><p>The test types for oil-immersed transformers cover the entire life cycle from manufacturing, installation to operation and maintenance. The test focuses at different stages vary: factory tests ensure qualified basic performance, type tests verify design limits, on-site tests guarantee installation quality, and preventive tests prevent operational failures. These tests together form an important guarantee for the safe and reliable operation of transformers.<\/p><p><strong>\u2163<\/strong><strong>.<\/strong><strong>Component inspection of oil-immersed transformer<\/strong><\/p><p>Component inspection of oil-immersed transformers is a crucial link to ensure their safe and stable operation, which mainly includes the following contents:<\/p><p><strong>1.<\/strong><strong>Appearance Inspection:<\/strong> Check whether the transformer's appearance is intact, whether there is oil leakage in the oil tank, and whether parts such as junction boxes, insulating bushings, and leads are damaged, rusted, or loose. At the same time, confirm that components like radiators, oil conservators, breathers, and oil level indicators are in normal condition.<\/p><p><strong>2.<\/strong><strong>Insulation Inspection:<\/strong> Use an insulation resistance tester to measure the insulation resistance between windings and ground as well as between windings themselves; the measured values should meet the specified standards. Additionally, conduct dielectric strength tests and insulating oil polarization tests to evaluate insulation performance.<\/p><p><strong>3.<\/strong><strong>Mechanical Operation Inspection:<\/strong> Check whether core equipment such as fans, coolers, pressure relief valves, and voltage regulating valves are operating normally. Ensure that bushings, connecting bolts, and terminal blocks are not loose, so as to guarantee the normal operation of mechanical components.<\/p><p><strong>4.<\/strong><strong>Oil Quality Inspection:<\/strong> Observe the color, odor, and transparency of transformer oil, and check for the presence of mixed impurities. Conduct tower-type oil sampling to inspect sediments and contaminants. Moreover, perform tests on transformer oil such as breakdown voltage, acid value, dielectric loss factor, moisture content, and particle size to determine if the oil quality is good.<\/p><p><strong>5.<\/strong><strong>Partial Discharge Detection:<\/strong> Use partial discharge detectors, such as installing UHF sensors or using high-frequency current transformers and ultrasonic sensors, to detect parts of the transformer such as windings and insulating bushings, and locate the position of the discharge source. If the partial discharge amount exceeds the specified value, the insulation risk needs to be evaluated.<\/p><p><strong>6.<\/strong><strong>Oil Temperature Inspection:<\/strong> Check whether the on-site gauge indications of the transformer's upper-layer oil temperature and high\/low winding temperatures are consistent with the readings on the control panel or CRT display. Verify if all temperatures are normal and whether they are close to or exceed the maximum allowable limits. At the same time, touch the surface of the radiating pipes by hand to check if the cooling device is in good condition.<\/p><p><strong>7.<\/strong><strong>Voltage and Current Inspection:<\/strong> Measure whether the voltage and current on the high-voltage side and low-voltage side of the transformer are within the normal range. Generally, the voltage on the high-voltage side must not exceed 105% of the nominal voltage value of its corresponding tap, to ensure the transformer operates within rated parameters.<\/p><p><strong>8.<\/strong><strong>Sound Inspection:<\/strong> A normally operating transformer emits a uniform \"buzzing\" sound. During inspection, pay attention to the presence of abnormal sounds such as sharp noises or crackling sounds. Abnormal sounds may be caused by internal faults or looseness and other reasons.<\/p><p><strong>\u2164<\/strong><strong>.<\/strong><strong>Certificate: <\/strong>CE, UL, ISO, SGS,

This effectively isolates conductors at different potentials and prevents short-circuit faults caused by insulation breakdown.<\/p><p><strong>\u00b7<\/strong><strong>Low Dielectric Loss and High Volume Resistivity:<\/strong> It has a small dielectric loss factor (tan\u03b4), resulting in low energy loss under electric fields and reduced heat generation. Meanwhile, its high volume resistivity (usually &gt;10\u00b9\u2074\u03a9\u30fbcm) minimizes leakage current, further enhancing insulation reliability.<\/p><p><strong>\u00b7<\/strong><strong>Filling Insulation Gaps:<\/strong> Solid insulating materials such as insulating paper and cardboard inside transformers have tiny pores. Mineral insulating oil can penetrate these pores, fill air gaps, avoid partial discharge caused by air ionization, and improve the overall dielectric strength of the insulation system.<\/p><p><strong>\u2461<\/strong><strong>Efficient Heat Dissipation to Maintain Stable Equipment Temperature Rise<\/strong><\/p><p><strong>\u00b7<\/strong><strong>Good Thermal Conductivity:<\/strong> Its thermal conductivity is approximately 0.12-0.15 W\/(m\u30fbK), much higher than that of air (about 0.026 W\/(m\u30fbK)), enabling it to quickly absorb heat generated by windings and iron cores.<\/p><p><strong>\u00b7<\/strong><strong>Convection Circulation Cooling:<\/strong> Heated insulating oil reduces in density, naturally rises to the radiator at the top of the transformer, exchanges heat with air through the radiator, cools down, and sinks, forming a circulation to continuously conduct heat out of the equipment.<\/p><p><strong>\u00b7<\/strong><strong>Synergy with Cooling Systems:<\/strong> In large transformers, mineral insulating oil can work with forced oil circulation cooling systems (such as oil pumps and cooling fans) to further enhance heat dissipation efficiency, meeting the needs of high-load operation.<\/p><p><strong>\u2462<\/strong><strong>Strong Chemical Stability to Extend Equipment Lifespan<\/strong><\/p><p><strong>\u00b7<\/strong><strong>Excellent Oxidation Resistance:<\/strong> Refined mineral insulating oil (e.g., derived from naphthenic or paraffinic crude oil) contains few impurities such as sulfur and nitrogen. It is not easily oxidized at high temperatures to form acids, colloids, or sludge, reducing corrosion and blockage of insulating materials.<\/p><p><strong>\u00b7<\/strong><strong>Low Volatility:<\/strong> It has a high boiling point and low volatility, so it is not prone to oil reduction or performance degradation due to volatilization during long-term operation, reducing maintenance frequency.<\/p><p><strong>\u00b7<\/strong><strong>Good Compatibility with Solid Insulation:<\/strong> It is well compatible with materials commonly used in transformers, such as cellulose paper and insulating cardboard, without chemical reactions that cause material aging, jointly maintaining the stability of the insulation system.<\/p><p><strong>\u2463<\/strong><strong>Arc Quenching and Protection to Enhance Operational Safety<\/strong><\/p><p><strong>\u00b7<\/strong><strong>Arc Quenching Function:<\/strong> When an arc is generated, the oil decomposes into gases such as hydrogen and methane, which can absorb arc energy. At the same time, the flow of oil can cool the arc area, quickly extinguishing the arc and preventing fault expansion.<\/p><p><strong>\u00b7<\/strong><strong>Isolating Air and Moisture:<\/strong> The oil layer covers the surface of internal components, isolating oxygen and moisture in the air, avoiding moisture-induced rust of metal components such as iron cores and windings, and reducing the risk of insulation deterioration.<\/p><p><strong>\u00b7<\/strong><strong>Fault Diagnosis Carrier:<\/strong> Insulating oil generates characteristic gases (such as acetylene and hydrogen) during faults. Through Dissolved Gas Analysis (DGA) technology, potential faults can be detected in advance, providing a basis for equipment condition assessment and maintenance.<\/p><p><strong>\u2464<\/strong><strong>Advantages in Economy and Practicality<\/strong><\/p><p><strong>\u00b7<\/strong><strong>Controllable Cost:<\/strong> Mineral insulating oil has wide raw material sources (based on petroleum refining), mature production processes, and relatively low prices, making it suitable for large-scale applications in various transformers (from distribution transformers to ultra-high voltage transformers).<\/p><p><strong>\u00b7<\/strong><strong>Convenient Maintenance: <\/strong>During normal operation, only regular monitoring of oil quality (such as moisture, dielectric loss, and breakdown voltage) is required. If necessary, filtration and regeneration treatments can restore its performance, with maintenance costs lower than some synthetic insulating oils.<\/p><p><strong>\u00b7<\/strong><strong>Strong Adaptability:<\/strong> It can maintain stable performance over a wide temperature range (e.g., good fluidity at low temperatures and resistance to deterioration at high temperatures), adapting to the operational needs of different climate regions.<\/p><p>Mineral insulating oil provides comprehensive operational protection for transformers through its four core roles: insulation, heat dissipation, chemical stability, and arc quenching protection. It is an indispensable key material in power systems. Its performance is directly related to the lifespan, efficiency, and safety of transformers, so it still dominates the power industry (although synthetic insulating oils are increasingly used in specific scenarios, mineral oil remains one of the most cost-effective choices).<\/p>","_padding":{"unit":"px","top":"20","right":"0","bottom":"0","left":"0","isLinked":false},"__globals__":{"typography_typography":""},"typography_typography":"custom","typography_font_family":"Arial","typography_font_size":{"unit":"px","size":16,"sizes":[]},"typography_line_height":{"unit":"px","size":20,"sizes":[]},"paragraph_spacing":{"unit":"px","size":20,"sizes":[]}},"elements":[],"widgetType":"text-editor"}\\\"]\\t\\t<\\\/div>\\n\\t\\t\\t\\t\\t<\\\/details>\\n\\t\\t\\t\\t\\t\\t<details id=\\\"e-n-accordion-item-2188\\\" class=\\\"e-n-accordion-item\\\" >\\n\\t\\t\\t\\t<summary class=\\\"e-n-accordion-item-title\\\" data-accordion-index=\\\"9\\\" tabindex=\\\"-1\\\" aria-expanded=\\\"false\\\" aria-controls=\\\"e-n-accordion-item-2188\\\" >\\n\\t\\t\\t\\t\\t<span class='e-n-accordion-item-title-header'><div class=\\\"e-n-accordion-item-title-text\\\"> 9.What protective measures does the Kete oil-immersed transformer have against overload, overheating, and short circuits? <\\\/div><\\\/span>\\n\\t\\t\\t\\t\\t\\t\\t<span class='e-n-accordion-item-title-icon'>\\n\\t\\t\\t<span class='e-opened' ><svg aria-hidden=\\\"true\\\" class=\\\"e-font-icon-svg e-fas-angle-down\\\" viewBox=\\\"0 0 320 512\\\" xmlns=\\\"http:\\\/\\\/www.w3.org\\\/2000\\\/svg\\\"><path d=\\\"M143 352.3L7 216.3c-9.4-9.4-9.4-24.6 0-33.9l22.6-22.6c9.4-9.4 24.6-9.4 33.9 0l96.4 96.4 96.4-96.4c9.4-9.4 24.6-9.4 33.9 0l22.6 22.6c9.4 9.4 9.4 24.6 0 33.9l-136 136c-9.2 9.4-24.4 9.4-33.8 0z\\\"><\\\/path><\\\/svg><\\\/span>\\n\\t\\t\\t<span class='e-closed'><svg aria-hidden=\\\"true\\\" class=\\\"e-font-icon-svg e-fas-angle-right\\\" viewBox=\\\"0 0 256 512\\\" xmlns=\\\"http:\\\/\\\/www.w3.org\\\/2000\\\/svg\\\"><path d=\\\"M224.3 273l-136 136c-9.4 9.4-24.6 9.4-33.9 0l-22.6-22.6c-9.4-9.4-9.4-24.6 0-33.9l96.4-96.4-96.4-96.4c-9.4-9.4-9.4-24.6 0-33.9L54.3 103c9.4-9.4 24.6-9.4 33.9 0l136 136c9.5 9.4 9.5 24.6.1 34z\\\"><\\\/path><\\\/svg><\\\/span>\\n\\t\\t<\\\/span>\\n\\n\\t\\t\\t\\t\\t\\t<\\\/summary>\\n\\t\\t\\t\\t<div role=\\\"region\\\" aria-labelledby=\\\"e-n-accordion-item-2188\\\" class=\\\"elementor-element elementor-element-5fb1d72 e-con-full e-flex e-con e-child\\\" data-id=\\\"5fb1d72\\\" data-element_type=\\\"container\\\" data-settings=\\\"{&quot;background_background&quot;:&quot;classic&quot;}\\\">\\n\\t\\t[elementor-element k=\\\"43aca594a86d0bbe94de5159700c1e94\\\" data=\\\"{"id":"9f1b9a3","elType":"widget","settings":{"editor":"<p>Kete oil-immersed transformers typically adopt multi-level protection measures, covering internal self-protection design, external monitoring devices, and relay protection systems.<\/p><p><strong>\u2460<\/strong><strong>Protection Measures Against \"Overload\"<\/strong><\/p><p>Overload refers to the situation where the transformer\u2019s load current exceeds the rated value for a long or short period, which may cause winding overheating and accelerated insulation aging.
