Description

Transformer bushing auxiliary maintenance device

technical field

The utility model relates to an auxiliary maintenance device for transformer bushings, which belongs to the technical field of transformer maintenance tools.

Background technique

After the transformer in the substation is used for a period of time, a lot of dust will fall on it, and there may be cracks in the porcelain parts or damage to individual parts, loose contacts, etc. In order to ensure the safe and normal operation of the transformer, it needs to be overhauled. Usually, the distance between the upper part of the transformer and the ground is more than 5 meters, and the height of the bushing on the top of the transformer is usually more than 7 meters from the ground. When the bushing on the top of the transformer is overhauled, the safety risk is relatively large. Because the bushing is cylindrical in shape, people need to ride on the bushing when performing maintenance on the bushing, and there is no support for the feet. At the same time, due to the high position of the bushing, it is difficult to find a suitable hanging point for the seat belt. The seat belt needs to be hung high and low. Therefore, there is a greater security risk.
