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...
