Laterally-placed pole

Abstract

The invention provides a laterally-placed pole. The laterally-placed pole comprises a pole shell, a vacuum arc-extinguishing chamber arranged in the pole shell and an electric connection part connected with the moving end of the vacuum arc-extinguishing chamber, wherein the pole shell is provided with a first sliding support structure which is horizontally arranged in the side placement state of aside placement pole; the electric connection part is provided with a second sliding support structure which is in sliding fit with the first sliding support structure; the electric connection part ismatched with the first sliding support structure of the pole shell through the second sliding support structure to realize sliding and supporting in the horizontal direction, so that the electric connection part does not droop due to the influence of gravity, the electric connection part, the arc-extinguishing chamber moving contact conducting rod and other devices can be kept horizontal, the guide sleeve of the arc-extinguishing chamber and the conducting rod of the arc-extinguishing chamber are not prone to friction, and opening and closing actions are smooth and not prone to clamping stagnation.

Description

[0001] The patent application of the present invention claims the right of priority, and the prior application as the basis of the priority is a Chinese utility model patent application named "a side-mounted pole" with application number 201921233352.6. technical field [0002] The invention relates to the field of circuit breakers, in particular to a side discharge pole with smooth opening and closing action and not easy to get stuck. Background technique [0003] The embedded pole is to embed the conductive parts related to the vacuum interrupter and the circuit breaker into an easily curable solid insulating material such as epoxy resin to form a pole, so that the entire circuit breaker pole becomes an integral part. [0004] The solid-sealed poles of conventional vacuum circuit breakers are usually placed vertically, that is, placed vertically. The moving end and the static end of the vacuum interrupter are in the same vertical direction, generally the static end faces up...

Problems solved by technology

[0004] The solid-sealed poles of conventional vacuum circuit breakers are usually placed vertically, that is, placed vertically. The moving end and the static end of the vacuum interrupter are in the same vertical direction, generally the static end faces upwards and the moving end faces downwards; but In the prior art, there are also poles placed on the side, that is, placed horizontally, the moving end and the static end of the vacuum interrupter are in the same horizontal direction, such as (SF 6 ) The solid-sealed pole in the inflatable cabinet is placed on the side; the side-laid pole is affected by gravity, and the self-gravity of the moving contact conducting rod of the arc extinguishing chamber, the soft connection (or the moving conducting rod of the sliding connection), etc., make The moving guide rod of the arc extinguishing chamber sags, so that the guide sleeve of the arc extinguishing chamber rubs against the conductive rod of the arc extinguishing chamber, which will cause the circuit breaker to be stuck in opening and closing, affect the performance of the circuit breaker, and even cause abnormalities such as breaking failure
