An isolating grounding switch and gis equipment using the isolating grounding switch

Abstract

The invention provides an isolating grounding switch and GIS equipment using the isolating grounding switch. The isolating grounding switch includes a shell, which is provided with an isolated static contact seat, a fast grounding static contact seat, a grounding static contact seat and a mounting base corresponding to each static contact seat, an isolation static contact seat, a fast grounding static contact seat and a grounding At least one of the static contact seats is adjustable in radial position on the corresponding mounting base through a position adjustment mechanism to realize the axial alignment of the static contact seat and the corresponding moving contact. At least one of the isolated static contact seat, the fast grounding static contact seat and the grounding static contact seat is adjustable connected to the installation base. The central axes of the moving contacts coincide with each other to ensure the centering arrangement of the two. When the moving contacts and the static contact seats are inserted into each other, it can reduce wear and tear, reduce the generation of metal foreign objects, and ensure the normal operation of the isolation grounding switch.

Description

Technical field [0001] The present invention relates to an isolating ground switch and a GIS device using the isolating ground switch. Background technique [0002] With the continuous development and innovation of science and technology in China's power industry, sf 6 Gas Insulated Metal-Enclosed Switchgear, Abbreviation GIS) has extensive applications in each voltage level substation installation engineering, isolated grounding switch as an important part of GIS equipment, play an important role. [0003] The authorization announcement date is March 19, 2014, an authorized notice number is a practical utility model for CN203491176U discloses a gas insulating metal closed switch device. The switching device includes a housing, and an isolated moving touch is provided in the casing. Touch, isolation static contact, and fast-grounded static contact, wherein the isolation movable contact and the isolation static contacts are fixed to the insulator, and the grounded static contact i...

AI Technical Summary

Problems solved by technology

[0004] In the above-mentioned switchgear, the static contact seats are all fixed on their corresponding installation bases. Once the alignment between the moving contacts corresponding to each static contact seat is not good or the guidance of the moving contacts is not good, the moving contacts will The wear and tear of the contact fingers in the static contact seat is aggravated, and more metal foreign objects will be generated, which will cause the insulation breakdown of the switchgear, lead to the failure of the isolating grounding switch and the fast grounding short circuit function, and cause irreversible damage to the entire product
