Abstract

The invention discloses an integrated permanent magnet mechanism vacuum switch. The structure of a traditional permanent magnet mechanism vacuum switch is redegined, the bellows is removed, components, such as the permanent magnet mechanism, moving and fixed contacts, a drive rod, an arc extinguishing system, etc., are all placed in the vacuum environment surrounded by a ceramic housing (all moving components are integrated in the ceramic vacuum housing), and wire connection terminals on two ends are fixedly connection with the ceramic vacuum housing (no relative movement exists), wherein one wire connection terminal is connected with the fixed contact, and the other wire connection terminal is in electrical connection with a conductive rod of the moving contact end through soft connection.

Description

technical field [0001] The invention belongs to the field of electric switchgear, and relates to an operating mechanism and an interrupter structure of a vacuum switch, in particular to a vacuum switch with an integrated permanent magnet mechanism. Background technique [0002] The permanent magnet mechanism vacuum switch is composed of a permanent magnet mechanism, a vacuum interrupter and other necessary mechanism components. It has the function of opening and closing operations, and is mostly used for the control and protection of power distribution lines. The vacuum switch with permanent magnet mechanism uses vacuum as the arc extinguishing medium. It has high breaking capacity and good environmental protection. It has been widely used in medium-voltage power distribution systems in industries such as electric power, mining, petroleum, transportation, and military industry. [0003] At present, the permanent magnet mechanism vacuum switch mainly uses a permanent magnet m...
