Abstract

The invention relates to an isolated earth switch and belongs to the technical field of high-voltage power transmission. The isolated earth switch comprises a metal shell, an isolating switch, an earth switch I, an earth switch II and the like, wherein the isolating switch comprises a body embedding member, a disk-shaped insulator, a fixed-side conductor, an isolating switch fixed contact, a rack movable touch rod, a gear and a movable-side conductor; the two earth switches include disc-shaped insulator body embedding members, movable-side conductors, earth switch fixed contacts, earth switch movable contacts, earth switch movable contact shielding cases, earthing terminals, earthing shells and insulating basins. The isolated earth switch has the characteristics of simple and compact structure, high reliability and the like, is capable of earthing the buses at the two sides of breaks of the isolating switch safely and synchronously, reducing the problem of serious abrasion of the contacts when the isolating switch and the earth switches are switched on and switched off, achieving steady and reliable motion of the movable contacts of the isolating switches and rapid and convenient earthing of the movable contacts of the earth switches, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to an isolating grounding switch, in particular to a three-phase common box-type isolating grounding switch for gas-insulated metal-enclosed switchgear, and belongs to the technical field of high-voltage power transmission. Background technique [0002] The isolating earthing switch is usually used in gas-insulated metal-enclosed switchgear (GIS) or composite electrical (PASS). It is not a separate product and is usually installed before and after the circuit breaker. At present, there are two main types of isolating and grounding switches that are common in the market: one is the traditional three-phase split cylinder structure, and the isolating switch and the grounding switch are separate GIS components. The three-phase split cylinder structure greatly increases the overall size of the GIS, and at the same time the manufacturing cost also increases; the other is that various manufacturers have introduced three-phase common box ...
