Product Description

The Oil Immersed Transformer is a high-performance transformer with more reasonable structure and better performance. The iron core is made of electrical steel strip, and the laminations at all levels are prepared in order according to the section shape of the iron core column and iron yoke. Each lamination must be stacked in a directional manner in strict accordance with the stacking order to reduce hysteresis loss and eddy current loss., Therefore, the performance is further improved, the loss is reduced, the noise is reduced, the three items are balanced, and the third harmonic component is reduced. Step down transformer is commonly used.This product is more suitable for urban and rural power grid transformation, industrial and mining enterprises, as well as for combined transformers and prefabricated transformer substations.
Oil Immersed Transformers use oil as the main insulation means of transformers and rely on oil as the cooling medium, such as oil immersed self cooling, oil immersed air cooling, oil immersed water cooling and forced oil circulation. The main components of the transformer are iron core, winding, oil tank, conservator, respirator, Pressure Relief Valve, radiator, insulating sleeve, Tap Changer, Gas Relay, thermometer, etc.
The noise of oil immersed transformer is low because the oil can penetrate into the silicon steel sheets of oil immersed transformer for a long time, and the transformer oil has elastic buffer effect.
Three phase oil immersed transformer adopts fully filled sealed corrugated oil tank shell, which is a permanently sealed oil tank with its own elasticity to adapt to oil expansion. Oil immersed transformer has been widely used in various power distribution equipment.

Compared with the ordinary oil immersed transformer, the oil conservator is canceled for the fully sealed transformer. The change of oil volume is automatically adjusted and compensated by the elasticity of the corrugated sheet of the corrugated oil tank. The transformer is isolated from the air, preventing and slowing down the oil deterioration and insulation aging, enhancing the operation reliability, and free of maintenance during normal operation.

The transformer core is made of high-quality cold-rolled silicon steel sheets, which greatly reduces the no-load loss and no-load current, and the core is bound to ensure the tightness of the core and reduce noise.
The transformer is mainly composed of iron core, winding, oil tank, insulating sleeve, tap changer, etc.
a. Low voltage winding of oil immersed transformer adopts cylindrical structure; High voltage winding adopts multi-layer cylindrical structure to balance the ampere turn distribution of the winding, with small magnetic leakage, high mechanical strength and strong short-circuit resistance.
b. The iron core and winding adopt fastening measures respectively, and the fastening parts such as the height and low-voltage lead are equipped with locknuts, which can withstand the shock of transportation.
c. The coil and iron core are vacuum dried, and the transformer oil is vacuum filtered and injected to minimize the moisture inside the transformer.
d. The oil tank adopts corrugated sheet, which has breathing function to compensate the volume change of oil caused by temperature change. Therefore, the product has no oil conservator, obviously reducing the height of the transformer.

e. As corrugated sheets replace oil conservator, transformer oil is isolated from the outside world, which effectively prevents oxygen and water from entering and leading to the decline of insulation performance.
