AI Technical Summary

Problems solved by technology

If the displacement is too large, the contact pressure between the contact and the contact fingers on the contact seat will be reduced, thereby increasing the contact resistance
This will not only lead to an increase in local temperature rise, but even affect the normal operation of the high voltage switch

Abstract

The invention relates to a contact base for connecting two contacts. The contact base includes a contact base body, at least one pair of contact fingers, and a pair of guide rings. The contact base body has a channel for inserting two contacts from the two ends, and an axial limiting hole. The contact fingers and the guide rings are positioned in the channel, and are arranged at the two ends of the channel from inside to outside. The contact base of the invention connects contacts through a simple structure. The contact base has the advantages of low cost and convenient operation. The relative displacement between the contacts and the contact base can be limited, and the contacts and the contact base can be prevented from failure in electrical contact. The invention further relates to a contact system for high-voltage switches which adopts the contact base.

Description

technical field [0001] The invention relates to a contact holder, in particular a contact holder for connecting two contacts. Furthermore, the invention also relates to a contact system for a high-voltage switch using such a contact holder. Background technique [0002] In high-voltage switches (especially gas-insulated metal-enclosed switchgear, referred to as GIS), coupling contacts are often required as connectors to solve the axial and radial differences when modules are docked. For example, in the compensator or cable connection mechanism of GIS, the contact and the contact seat constitute the contact system and are enclosed in a housing filled with insulating gas. The contacts may be part of or connected to the conductors and connected via the contact sockets. The existing contact system is complex in structure, high in cost and inconvenient to assemble and disassemble, especially when limited by the space of the housing. At the same time, the shape of the high-volt...
