Transformer oil tank

The utility model relates to the technical field of transformer oil tanks, and discloses a transformer oil tank which comprises a main body mechanism, a heat dissipation mechanism and a switch mechanism, the heat dissipation mechanism is located in the main body mechanism, the switch mechanism is located above the heat dissipation mechanism, and the main body mechanism comprises a mounting plate, a mounting hole, a base, an oil tank shell and a limiting hole. The mounting hole is fixedly formed in the middle of the mounting plate, the base is fixedly mounted at the upper end of the mounting plate, the oil tank shell is fixedly mounted at the upper end of the base, and the limiting hole is fixedly formed in the middle of the upper end of the oil tank shell. According to the transformer oil tank and the transformer thereof, whether the transformer works in a high-temperature environment or not can be sensed through the temperature control switch, the working environment of the transformer can be controlled, the
