Abstract

The invention relates to the field of high-voltage switches, particularly to an isolation grounding switch mechanism, a single-pole component and GIS electrical equipment. The isolation grounding switch mechanism includes a housing and an isolation switch and a grounding switch which are assembled on the housing in L-shaped distribution, the isolation switch includes an isolation switch moving contact and an isolation switch static contact, the grounding switch includes a grounding switch moving contact and a grounding switch static contact, a connection contact seat used for being electrically connected with a voltage transformer is arranged between the isolation switch and the grounding switch, the isolation switch static contact and the grounding switch moving contact are integrated on the connection contact seat, the isolation switch moving contact is electrically connected with a main conductive loop, and the grounding switch moving contact is electrically connected with ground potential. The isolation switch and the grounding switch are combined together, overall components and butting faces are few, and the structure is simple and compact.

Description

technical field [0001] The invention relates to the field of high-voltage switches, in particular to an isolation and grounding switch mechanism, a single-pole assembly and GIS electrical equipment. Background technique [0002] At present, in the gas-insulated metal-enclosed switchgear (GIS), in order to realize the matching of the induced current of the voltage transformer and the grounding protection of the voltage transformer, many voltage transformers are equipped with an isolation grounding mechanism, and now most of them use a separate isolation, The grounding mechanisms respectively realize corresponding functions, so that there are many overall components and the cost is relatively high. Therefore, it is necessary to design a combined mechanism of an isolating switch and a grounding switch for a voltage transformer. Contents of the invention [0003] The object of the present invention is to provide a compact isolating and grounding switch mechanism, and a single...
