Abstract
A vacuum switch gear provided with a vacuum container grounded within a grounded vacuum container or a gas-insulated ground container, and a pair of buses connected to an external conductor of the switch gear. A portion for connecting the buses and the external conductor is interface insulation in which an elastic body and solid insulation are utilized in combination. The interface insulation performs adhering and tightening work by rotating an adjuster from the outside.
Claims13
A vacuum switch gear, comprising:
- a vacuum container;
- a fixed electrode placed within said vacuum container and connected to an external conductor, said external conductor being insulated by a solid insulation;
- a movable electrode adapted to be connected to and disconnected from said fixed electrode;
- an operation mechanism unit for driving said movable electrode;
- and
- a pair of buses connected to said external conductor;
- wherein a portion for connecting said buses and said external conductor is provided so that an end of the external conductor insulated by the solid insulation and extended from said vacuum container and the pair of buses connected to the end are supported by an interface insulation.
