Abstract
The switchgear includes a vacuum circuit breaker that is disposed in a circuit breaker chamber compartmented by a grounded metal plate, a busbar that is disposed in a busbar chamber and connected to the vacuum circuit breaker through a conductor, a cable that is disposed in a cable chamber and connected at one end to a load side, and a grounding device that is operated by a grounding device actuator disposed in a grounding device actuator chamber, connected to the vacuum circuit breaker through a conductor, and connected to the other end of the cable. The busbar is formed by a solid-insulated busbar. The conductor connecting the vacuum circuit breaker to the busbar and the conductor connecting the vacuum circuit breaker to the grounding device are both formed by a solid-insulated conductor. The circuit breaker chamber and the grounding device have a sealed structure.
