Claims

[Scope of utility model registration request]

A cylindrical fixed-side charged part that has an electric field shield part that alleviates the electric field between it and the container and supports a fixed-side contact that approaches and separates from a movable contact is generated when both contacts open. In a gas insulated device provided with an exhaust port for insulating gas that is blown to extinguish an arc, the exhaust port is provided with a guide member made of an insulating material that guides the exhaust gas away from the electric field shield portion of the stationary side live part. Gas insulated equipment featuring:
