Baoding oil-immersed transformer is mainly insulated by oil and relies on oil as cooling medium, such as oil-immersed self-cooling, oil-immersed air-cooling, oil-immersed water-cooling and forced oil circulation. The main components of transformer are iron core, winding, oil tank, oil pillow, respirator, explosion proof pipe (pressure release valve), radiator, insulation sleeve, tap switch, gas relay, thermometer, oil purifier and so on.

Baoding oil-immersed transformer silicon steel sheet layer, due to long-term immersion in the transformer, oil can infiltrate into it, and the transformer oil has elastic buffer effect, so baoding oil-immersed transformer noise is small. But the pressure switch in the tank inside, the pressure switch contact is not good outside can not be seen, such as contact is not equal to the circuit breaker, such as poor contact, when the load is too large when it is easy to burn the switch. Baoding in oil-immersed transformer cooling conditions, can be run as stipulated in the nameplate, but not more than 90 ℃, the highest top oil temperature to prevent transformer insulation aging, the top oil temperature should not be commonly more than 85 ℃, often alarm fixed value setting at 80 ℃. There are two common cooling methods as follows :(1) oil-immersed transformer usually adopts oil-immersed self-cooling, oil-immersed air-cooled and forced oil circulation.

(2) oil-immersed self-cooling type relies on the natural convection of oil to take away heat. Oil-immersed air-cooled type is on the basis of oil-immersed self-cooled type, plus fan to fuel tank and tubing blower, to strengthen the role of heat dissipation. Forced oil circulation is to use a pump to pump the hot oil from the transformer outside the transformer to cool before feeding into the transformer.
