The Oil Immersed Transformer is a high-performance transformer with a more reasonable structure and better performance. The iron core is made of an 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 directionally in strict accordance with the stacking order to reduce hysteresis loss and eddy current loss. Therefore, the performance is further improved, the loss and noise are effectively reduced, the balance of the three is achieved, and the third harmonic component is reduced. Step down transformer is commonly used. This product is more suitable for the upgrading of urban and rural power grids, can meet the power needs of industrial and mining enterprises, and is also an ideal choice for combined transformers and prefabricated substations.

Oil-immersed transformers achieve their main insulation function through oil and rely on oil as a cooling medium. It has different cooling methods, including oil-immersed self-cooling, oil-immersed air cooling, oil-immersed water cooling, and forced oil circulation. The main components of a transformer include an iron core, winding, fuel tank, oil reservoir, breathing apparatus, pressure relief valve, heat sink, insulating bushing, tap changer, gas relay, and thermometer.

The noise of an oil-immersed transformer is low because the oil can penetrate the silicon steel sheets of the oil-immersed transformer for a long time, and the transformer oil has an elastic buffer effect.

Main Functions And Features

Adopt corrugated plate type or expansion type radiator tank. Because there is no need for an oil reservoir, the height of the transformer is reduced, and because the transformer oil does not shrink with the air, the aging of the oil is slowed down, thus extending the service life of the transformer. The no-load loss of the S10-M is 20% lower than that of the S9-M, and the S11-M is 30% lower than that of the S9-M.
