A tool for installing the bushing of vacuum circuit breaker

Abstract

The invention discloses a tooling for installing a bushing of a vacuum circuit breaker. The top threaded connection of rod (31), the other end of driving rod (1) is threaded connected with the top of right side vertical pressure bar (32); The middle part is hinged, and the other end of the support beam (4) is hinged with the middle part of the right side vertical pressure bar (32); the top of the support column (5) is fixed on the support beam (4); the bottom of the support column (5) is fixed on On the support pressure plate (7); the bottom end of the left vertical pressure bar (31) is provided with the left sleeve clamp (61); the bottom end of the right vertical pressure bar (32) is provided with the right sleeve Clip (62). The embodiment of the present invention not only greatly improves the installation efficiency and installation quality of the sleeve installation, enhances the stability and reliability, but also makes the cooperation between the silicone sealing ring and the sleeve and the installation hole of the sleeve more tightly without generating air bubbles, This ensures that the vacuum circuit breaker can meet the requirements of high protection level and insulation.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a tool for installing a bushing of a vacuum circuit breaker. Background technique [0002] As we all know, the pole and the sleeve are two important components of the vacuum circuit breaker; the pole is arranged in the switch box; the sleeve extends from the outside of the switch box into the switch box, and is fixed on the pole. Each vacuum circuit breaker includes two types of bushings, the bushing on the incoming line side and the bushing on the outgoing line side. For a long time, there are two main positional relationships between the bushing and the switch box of the vacuum circuit breaker: one is that the bushing on the inlet side and the bushing on the outlet side are arranged parallel to each other on the top of the switch box; the other is The inlet-side bushing (or outlet-side bushing) is arranged on the top of the switch box, and the outlet-side bushing (or ...

AI Technical Summary

Problems solved by technology

[0005] (1) Due to uneven force, the silicone sealing ring between the casing and the pole is prone to serious deformation

[0006] (2) The nylon wire used for exhaust is inserted into the sleeve installation hole of the pole together with the sleeve. It is very laborious to take out the nylon wire, and sometimes the silicone sealing ring will be damaged, so that the joint between the sleeve and the pole A large number of air bubbles are generated, causing the vacuum circuit breaker to fail to meet the insulation requirements

[0007] (3) This manual pushing method requires at least two workers to cooperate to complete the casing installation, and sometimes even three or four workers to complete it together, which is not only time-consuming, but also consumes a lot of labor costs
