Abstract

The invention discloses a removal tool for a transformer respirator and relates to a maintenance tool for electric power facilities. The removal tool for the transformer respirator comprises a frame, two movable pieces and two positioning heads; the frame with both ends symmetrical is provided with two flat plates and is of an arc plate structure; each movable piece is fixed on the flat plate at the end of the frame by means of bolts; a long slotted hole is arranged in the middle of the movable piece; two bolts passing through the long slotted hole are fixed to bolt holes on the flat plates; nuts at the end of the bolts are positioned below the flat plates; each positioning head of a ladder shaft structure is fixed on the upper surface of each movable piece; and the two positioning heads located on the two movable pieces are of the same structure and are symmetrical. The removal tool for the transformer respirator has the advantages that an oil seal bowl of the transformer respirator can be quickly removed, the structure of the removal tool is simple, and removal operation can be completed within a small space with no damage produced to the respirator.

Description

technical field [0001] The invention relates to a power facility maintenance tool. Background technique [0002] A large number of transformers are installed in the power supply and distribution systems of various manufacturing enterprises at home and abroad, which are mainly used to provide electric energy for production equipment and various auxiliary equipment. The transformer is mainly composed of coils, high and low voltage bushings, oil tanks, oil pillows, respirators and other components. [0003] The breather is the main part of the transformer. It is connected to the oil conservator through the pipeline to communicate with the atmosphere and the inside of the transformer oil tank. The respirator is equipped with color-changing silica gel to absorb moisture in the air and prevent moisture from entering the transformer oil tank to reduce the insulation level of the insulating oil. The respirator is a cylindrical structure, the top is connected to the oil pillow thro...
