A large-capacity oil-immersed transformer

Abstract

The invention discloses a large-capacity oil-immersed transformer. The structure includes a mounting bracket, a box body, a cooling fin, a top plate, a high-voltage bushing, a low-voltage bushing, and an alarm device. The side of the box body is provided with a cooling fin. The installation bracket is welded, the top of the box is connected to the top plate, and the top plate is respectively installed with high-voltage bushings and low-voltage bushings. The alarm device is located below the box and connected to the bottom of the box. The container, the water replenishment tank, the diversion cover, the top of the straight container is connected with the bottom of the collection tube, the side of the straight container is connected with the water replenishment tank, the floating device is arranged in the straight container and the collection tube, and the top of the floating device is connected with the bottom of the box body. The beneficial effect is that the water level is increased by the leaked oil as power, and the distance is increased by the lever, so that the switch is triggered to alarm, the staff can be notified in time, the maintenance time is shortened, and the accident rate is reduced.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a large-capacity oil-immersed transformer. Background technique [0002] The transformer is one of the important equipment in the building power supply and distribution system. The transformer is divided into oil-immersed transformer and dry-type transformer. The tank of the oil-immersed transformer is filled with oil, which can solve the problem of large-capacity heat dissipation and insulation of the transformer. [0003] Oil-immersed transformers are poorly sealed and should be aged. Oil leakage may occur in the operating place, affecting the safe operation of equipment. When oil leakage occurs, the staff cannot be reminded in time, and maintenance cannot be carried out in time. The longer the delay, the more likely accidents will occur. Contents of the invention [0004] The main purpose of the present invention is to overcome the deficiencies of the prior art and provide a larg...
