Telescopic isolation switch upper conductive arm replacement tool

Abstract

The invention provides a telescopic isolation switch upper conductive arm replacement tool, which comprises two vertically arranged telescopic lead screws, a horizontal sliding rod and a groove-type sliding block, and is characterized in that the horizontal sliding rod and the groove-type sliding block matched with each other in a sliding mode, two ends of the upper surface of the groove-type sliding block are provided with upper hoops respectively which are matched with an isolation switch upper conductive arm, the lower part of the groove-type sliding block is set to be a sliding groove and is arranged on the horizontal sliding rod in a sleeved mode, two ends of the horizontal sliding rod are connected with one ends of the telescopic lead screws in a hinged mode respectively, and the other ends of the two telescopic lead screws are provided with lower hoops which are matched with an isolation switch lower conductive arm. By using the replacement tool provided by the invention, complex and tedious manual operations in replacement of the upper conductive arm can be simplified into mechanical adjustment and alignment in two dimensions, thereby greatly improving the work efficiency, reducing the labor intensity, reducing the personnel investment.

Description

technical field [0001] The invention relates to the technical field of maintenance of high-voltage isolating switches of 220kV and above, in particular to a replacement tool for an upper conductive arm of a retractable isolating switch. Background technique [0002] During the operation of the outdoor telescopic isolating switch, its conductive arms are all exposed to the atmosphere, and the operating environment is harsh. Under the erosion of rainwater for many years, the clamping spring, the through-hole connecting rod and other parts in the conductive arm of the knife switch are easy to rust. And the jamming caused problems such as that the moving and static contacts of the knife switch were not clamped tightly after closing, the opening could not be opened, and the opening could not be inserted, etc., and the upper conductive arm needed to be replaced. At present, the reassembly of the upper conductive arm mainly depends on the tacit cooperation of the staff on the aeria...

AI Technical Summary

Problems solved by technology

Since the replacement of the upper conductive arm is a high-altitude operation, and the weight of the conductive arm is not light, it is very difficult to align the through-hole connecting rod and the screw hole when reinstalling the new upper conductive arm

This alignment work requires the accurate command of the on-site commanders and the skilled operation of the crane driver. Often, only one can be reinstalled in a morning, which is inefficient.
