Special tooling platform for maintenance of folding arm disconnecting switch

Abstract

The invention provides a special tooling platform for maintenance of a folding arm disconnecting switch. The special tooling platform for the maintenance of the folding arm disconnecting switch comprises a base, upper conductive arm first and second fixing members fixed on the base, spring disassembling and assembling first and second fixing members, and a spring compression assembly; the spring compression assembly comprises a guiding rod connected to the spring disassembling and assembling first and second fixing members at two ends separately, a spring pressing member movably sleeved on theguiding rod, a transmission screw rod movably disposed on the spring disassembling and assembling second fixing member, and a screw hand wheel fixed at one end of the transmission screw rod; the other end of the transmission screw rod is fixedly connected to the spring pressing member; the upper conductive arm first fixing member and the spring disassembling and assembling first and second fixingmembers are separately provided with adjustable clamping mechanisms; and the upper conductive arm second fixing member is provided with a 360-degree rotating hoop. When the special tooling platform for the maintenance of the folding arm disconnecting switch is used, the folding arm disconnecting switch and related components can be effectively fixed for disassembling, assembling and maintenance,which is easy to operate, saves time and effort, and can effectively improve maintenance efficiency and maintenance quality.

Description

technical field [0001] The invention relates to an auxiliary tool for maintenance of a folding-arm type isolating switch, in particular to a special tooling platform for maintenance of a folding-arm type isolating switch. Background technique [0002] 110kV, 220kV folding arm type disconnectors (such as SPV, SPO, GW16, GW17, GW22, GW23 and other types of folding arm type disconnectors) have compact structure, small footprint, large current carrying capacity, and good sealing of moving parts , high safety and reliability, and many other characteristics, it is an ideal equipment for the layout of incoming and outgoing lines of substations, and has been widely used in power grids. During the long-term use of the folding arm isolating switch, it is greatly affected by the outdoor environment. The upper and lower conductive arms of the folding arm isolating switch are prone to rust and jamming. Components such as covers and fasteners are easily seized due to corrosion, which mak...

AI Technical Summary

Problems solved by technology

The traditional method of on-site maintenance of the folding arm isolating switch is that the maintenance personnel rely on relatively simple tools and tools, and use methods such as hammering, wrench screwing, screwdriver prying, etc. The fixing of the folding arm isolating switch requires the cooperation of multiple people during maintenance, The disassembly and assembly of the moving contact and the clamping spring is more difficult, time-consuming and labor-intensive, and it is easy to damage the relevant components of the folding arm type disconnector

[0003] Aiming at many problems existing in the traditional way of overhauling the folding arm isolating switch, some simple tooling platforms for auxiliary maintenance of the folding arm isolating switch have appeared in recent years. This kind of tooling platform is usually only for a certain type of folding arm isolating switch The structure is simple and the function is single, and the applicability is not strong; it is not convenient and flexible enough to fix and disassemble the objects that need to be overhauled, such as the assembly of the moving contact of the folding arm type isolating switch and the clamping spring in the upper conductive tube of the upper conductive arm. ; Most of them are fixed tooling platforms, and the quality is heavy, it is not easy to carry and set up on-site stations, and it is more troublesome to use
