Multipurpose portable high-voltage isolating switch overhaul worktable and using method thereof

Abstract

The invention discloses a multipurpose portable high-voltage isolating switch overhaul worktable. The multipurpose portable high-voltage isolating switch overhaul worktable comprises a worktable board and multiple foldable support legs which are hinged to the worktable board and are used for supporting the worktable board; rolling wheels are arranged at the bottom of the worktable board; and at least one foldable support leg can be turned to the upside of the worktable board. The overhaul worktable can be folded, so that relatively small space is occupied; a platform plate which is made from a polyformaldehyde resin material is light in weight and convenient to carry; the rolling wheels are arranged at the bottom of the worktable board, and the multipurpose portable high-voltage isolating switch overhaul worktable can be used as a trailer by folding one foldable support leg at the bottom of the worktable board and turning another foldable support leg to the upside of the worktable board, so that the high-voltage isolating switch overhaul worktable can be used for multiple purposes, is convenient to carry tools and various modular fixtures and is convenient to use, the work efficiency can be improved greatly, and the labor intensity can be reduced; meanwhile, a series-hole modular fixture structure is formed on the worktable board and via holes are formed in the worktable board, so that more convenience is brought to assembly and disassembly of the isolating switch overhaul fixtures, the work precision can be ensured, and the work efficiency as well as the process quality can be improved.

Description

technical field [0001] The invention relates to a substation inspection and maintenance work tool, in particular to a multi-purpose portable high-voltage isolating switch maintenance workbench and a usage method thereof. Background technique [0002] The isolating switch is the most widely used switching device in high-voltage power transmission and transformation. Most of the high-voltage isolating switches are installed outdoors and are directly affected by the environment. After a long time of operation, the conductive part will rust and oxidize and produce resistance. According to the resistance and temperature Relationship, the contact fingers will generate heat and deformation when they pass through a large current load. If the rotating parts are jammed or stuck during the operation, they may not fit properly and cause arc burns on the contact surface, and they will not be able to continue to operate, which will seriously affect the operation reliability of the substat...

AI Technical Summary

Problems solved by technology

If the rotating parts are jammed or stuck during the operation, they may not fit properly and cause arc burns on the contact surface, and they will not be able to continue to operate, seriously affecting the operation reliability of the substation equipment. In order to restore the isolating switch to its original state The normal function required by the technical standard requires disassembly and overhaul of the isolating switch

[0003] With the continuous improvement of the level of substation maintenance work, the requirements for the quality of the maintenance process are becoming more and more stringent. When the disconnector is overhauled, the equipment should be disassembled and reassembled. The traditional method of dismantling and overhauling is to spread a piece of plastic cloth on the workplace, and the staff Squatting on the ground for disassembly, the work process is more labor-intensive, and dismantling on the spot has certain disadvantages, it is difficult to meet the process requirements, it is easy to cause unnecessary damage to the equipment, and affect the appearance and installation effect of the equipment

However, the existing isolation switch maintenance platform is not only inconvenient to carry, but also has a single function and is not convenient to use
