Description

Technical Field

[0001] The utility model belongs to the technical field of electric power maintenance, and in particular relates to a universal transformer knife switch maintenance rack. Background Art

[0002] At present, when overhauling 66 kV knife switches, a holding rod is often used to lift the conductive part of the knife switch together with the porcelain column and the rotating bearing seat at the lower end, and then hoist it as a whole after the repair is completed. There are also methods such as disassembling each part and transferring it to the ground, and then uploading and installing it one by one after repair. This makes the maintenance workload and labor intensity large and prolongs the maintenance period. In particular, workers working at heights are not protected by safety protection measures, and there is no place to fix the safety belt, which is very easy to cause personal accidents. The overhaul of 66 kV switches and knife switches is an important work carried out by the substation inspection profession all year round, accounting for more than 1 / 3 of the annual maintenance and maintenance workload, and is characterized by high labor intensity, long operation time, and a large number of people.
