摘要： A vacuum switchgear system, which comprises a plurality of vacuum switchgears each comprising a vacuum container for accommodating the desired number of vacuum switches selected from a disconnecting switch or load break switch, an earth switch and an vacuum circuit breaker. Each of the vacuum switches has connecting terminals. The switchgears constitute different types of switchgears, the switchgears being classified into the power receiving side and power distribution side. The switchgears are connected with the adjoining switchgear or an element selected from an arrester and a PCT by means of an insulated connecting conductor having terminals around both ends thereof. The terminals are electrically connectable with and detachable from the connecting terminals of the switchgears.

摘要： Disclosed is a vacuum switchgear comprising an electro-conductive outer vacuum container, a plurality of inner container disposed in the outer vacuum container. The inner containers and the outer container are electrically isolated from each other. The outer container is made of stainless steel plate, for example. One of the inner vacuum containers accommodates a ground switch for keeping the circuit open while the switchgear is opened, having a movable electrode connected to an operating mechanism, and a fixed electrode connected to fixed electrode rod. Another inner vacuum container accommodates a function switch capable of having at least one of functions of a circuit breaker, a disconnector and a load switch. A plurality of electrode shields each surrounds the electrodes of the ground switch and of the function switch. The ground switch and the function switch are disposed in separate vacuum inner containers, respectively.
