Abstract

The invention relates to an overhauling tool to disassembling equipment in a transformer substation, in particular to an overhauling disc for a protective cover of a disconnecting switch moving contact. The overhauling disc for the protective cover of the disconnecting switch moving contact comprises a cylindrical base (1), the two opposite ends of the cylindrical base (1) are respectively provided with a fixing pin (2), a circular groove (4) is formed in the position, between the two fixing pins (2), of the cylindrical base (1), and a square inserting hole (3) is formed in the circular groove (4). The overhauling disc for the protective cover of the disconnecting switch moving contact can fully solve the problems that the protective cover of a GW16 type disconnecting switch moving contact is inconvenient to disassemble and the like, structural damage and cracking of the protective cover due to instable locating in the overhauling process can be avoided, the working efficiency of personnel can be improved, working time can be saved, and working intensity can be lowered.

Description

technical field [0001] The invention relates to a tool for dismantling and overhauling equipment in a substation, in particular to a disc for overhauling a protective cover of a moving contact of an isolating switch. Background technique [0002] During the daily operation of the isolating switch of the 220kV substation, the staff need to regularly check and maintain the equipment. Among them, the conductive contact of the GW16 disconnector consists of a protective cover and a moving contact. According to the requirements of the maintenance process, the staff must disassemble and repair the moving contact, in order to effectively overcome the inconvenience of dismantling the protective cover of the moving contact of the GW16 type disconnector, and avoid structural damage and cracking of the protective cover during maintenance due to unstable positioning , to improve the efficiency of personnel operations, save working time, improve the maintenance process, and reduce the in...
