摘要： A vacuum switch comprises a first vacuum container containing therein a circuit breaker, a second vacuum container containing therein the first vacuum container and grounded, and a third vacuum container connected to the second vacuum container, containing therein a disconnecting switch and an earth device and grounded. The second and third vacuum containers are isolated in vacuum from the first vacuum container, and the second vacuum container is electrically insulated from the first vacuum container. The second vacuum container contains an insulator fixed to a conductor connected to the circuit breaker and a movable rod partially disposed out of the vacuum containers and operating the circuit breaker to open and close. The disconnecting switch, circuit breaker and the insulator are arranged in a line. A vacuum switchgear comprises the above-mentioned vacuum switches of the number corresponding to three phases and necessary components, each being contained in a metal box.
