縮小形開閉装置用接地開閉器。 A fixed contact attached to a bus bar in a metal container, an indirect grounding contact having the same axis as the fixed contact, and coaxially located between the two contacts and having an inner diameter larger than both the contacts. A direct grounding contact, an insulating cylinder for puffer which has the same axis and the same inner diameter as the direct grounding contact and is arranged between the indirect and direct grounding contacts, a tip part, and an intermediate part. The base end has first, second, and third fitting parts for fitting into the fixed contact, the direct grounding contact, and the indirect grounding contact in this order, and the second fitting part is inserted into the cylinder. a movable conductor inserted into a cylinder or the like so as to be slidably positioned; an intermediate nozzle consisting of a plurality of through holes formed in a second fitting portion of the movable conductor;
and an insulating layer formed on the surface between the first and second fitting portions of the moving conductor.
