Abstract
The utility model belongs to an isolating and grounding combination switch applied to SF6 gas-insulated metal-enclosed switchgear (GIS) equipment and relates to a novel three-position switch, which comprises a grounding contact, a stationary contact seat and a sliding contact seat. The grounding contact, the stationary contact seat and the sliding contact seat are arranged on a shell. The novel three-position switch is characterized in that the grounding contact, the stationary contact seat and the sliding contact seat are of an embedded spring type contact finger structure respectively. The novel three-position switch has the advantages of simple structure, reliable performance, small size and the like. Due to the adoption of spring type contact fingers, the cost is greatly reduced and the production efficiency is improved. Meanwhile, the competitiveness of products is enhanced. The above technical scheme of the utility model is mainly applied to isolating and grounding switches for 126kV gas-insulated metal-enclosed switchgear (GIS) equipment.
Description
