Isolation grounding switch arc contact base and isolation grounding switch

Abstract

The invention belongs to the field of high-voltage switches and relates to an isolation grounding switch arc contact base and an isolation grounding switch The isolation grounding switch arc contact base comprises a conductive connecting body; the connecting body is provided with a first connecting structure used for being fixedly matched with a static end contact seat, a second connecting structure used for installing an isolation static arc contact and a third connecting structure used for installing a grounding static arc contact. When the isolation grounding switch arc contact base is used, the isolation static arc contact and the grounding static arc contact are directly installed on the connecting body, and the connecting body is fixed with the static end contact seat, so that the assembly of the grounding static arc contact and the isolation static arc contact can be completed; and compared with the prior art, bases of an original grounding static arc contact and isolation static arc contact can be omitted, so that the number of parts is reduced, and the problem that an isolation grounding switch is low in assembly efficiency and the problem that parts of theisolation grounding switch are inconvenient to manage are solved.

Description

technical field [0001] The invention relates to the field of high-voltage switches, in particular to an arc contact base of an isolation grounding switch and an isolation grounding switch. Background technique [0002] In combined electrical appliances, the isolation grounding switch is an important part. The main components of the isolation and grounding switch include the housing, the static end contact seat, the moving end electrical connection, the main contact, the arc contact and the corresponding operating mechanism, etc., wherein the main contact includes the grounding moving main contact, the grounding static main contact Contacts, isolated moving main contacts and isolated static main contacts, arcing contacts include grounding moving arcing contacts, grounding static arcing contacts, isolated moving arcing contacts, and isolated static arcing contacts. Among them, the arc contact is made of high temperature resistant and ablation resistant material. When closing...
