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.
