備えたガス絶縁開閉装置。 A container that houses a main circuit live part and is filled with insulating gas, a through hole formed in the container, and a grounding contact whose tip is connected to and separated from the live part by passing through the through hole and has a ground potential. a sealing means that airtightly closes the space between the contact and the periphery of the through hole; and a sealing means that urges the contact in a direction away from the live part with a spring force smaller than atmospheric pressure to reduce the vacuum in the container. A gas insulated switchgear comprising: a spring that causes the contactor to come into contact with the charging part due to external pressure when pulled.
