Product Description

The Oil Immersed Transformer has the characteristics of good heat dissipation, low loss, large capacity, low price, etc. Its main role in the power grid is the conversion of electric energy, that is, the conversion of voltage level. It is understood that most of the power transformers operating in the power grid are Oil Immersed Transformers.
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. 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.

The oil tank is the shell of the transformer, in which the iron core and winding are installed and filled with transformer oil. For the transformer with large capacity, the radiator or heat pipe is installed outside the oil tank. The common oil immersed transformer oil has an oil conservator, which plays a larger role, and the common oil immersed transformer oil conservator plays a higher role. The conservator is also called oil tank. The transformer oil will expand with heat and contract with cold due to temperature change, and the oil level will also rise or fall with temperature change. The function of the conservator is to leave a buffer space for the thermal expansion and cold contraction of the oil, so as to keep the oil tank always full of oil; At the same time, due to the oil conservator, the contact area between oil and air is reduced, which can slow down the oxidation of oil.
