A soft connection test tool

Abstract

The invention relates to a flexible connection testing tool which comprises a testing frame, an adjustment block disposed on the testing frame and used to be firmly connected to a fixation end of flexible connection as well as a movable slide block assembled on the testing frame in a vertical guiding manner and connected to a movable end of the flexible connection, wherein the adjustment block can horizontally adjust a size between the adjustment block and the movable slide block by an adjustment structure and can be fixed after adjustment, and the flexible connection testing tool also comprises a driving mechanism which can drive the movable end of the flexible connection and the movable slide block to move up and down. The movable slide block is used to simulate a movable end of a vacuum arc extinction room, and the adjustment block can adjust a distance between the adjustment block and the movable slide block, so that a length of the flexible connection between a solid-sealed polar pillar and the movable end of the vacuum arc extinction room during actual work of the flexible connection can be simulated; actual working conditions of the flexible connection in the actual work can be simulated well; and performance of the flexible connection can be tested more authentically.

Description

technical field [0001] The invention relates to a testing tool for performance testing of a soft connection used in a solid-sealed pole. Background technique [0002] In recent years, intelligence, miniaturization, and long life have gradually become the mainstream direction of switchgear development. Solid-sealed pole vacuum circuit breakers have gradually replaced open-type vacuum interrupters or vacuum circuit breakers with insulating cylinders covering the interrupter. , become a trend of switchgear. The solid-sealed pole includes upper and lower outlet seats and a vacuum interrupter, and the lower outlet seat and the moving end of the vacuum interrupter are electrically connected through a flexible connection to form a main conductive circuit. As a bridge to build a conductive circuit, the soft connection not only plays the role of conducting the conductive circuit, but also moves up and down with the switch of the vacuum interrupter, which requires the soft connection...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many manufacturers of soft connections on the market, and their use is not limited to solid-sealed poles, which results in no uniform standard for the performance of soft connections in the market. In the field of circuit breakers, the performance of soft connections directly affects and Restrict the breaking performance of the circuit breaker
