Description

Technical Field

[0001] This application relates to the technical field of auxiliary maintenance tools for transformers, and particularly to an auxiliary maintenance device for transformer bushings. Background Art

[0002] After a transformer in a substation has been used for some time, a lot of dust will fall on it, and there may also be situations such as porcelain part cracks, damage to individual parts, and loose connections. To ensure the safe and normal operation of the transformer, it needs to be overhauled. Usually, the upper part of the transformer is more than 5 meters above the ground, and the height of the bushing at its top is often greater than 7 meters. Due to the excessive height of the bushing from the ground, an auxiliary maintenance device is required to assist workers during the maintenance of the bushing.

[0003] Due to the high position of the bushing, it is difficult to find a suitable hanging point for the safety belt. The safety belt needs to be hung high and used low, and the existing auxiliary maintenance devices cannot protect workers, presenting potential safety hazards. For this reason, an auxiliary maintenance device for transformer bushings is proposed. Utility Model Content
