A switchgear wherein a connecting portion to be connected to a transmission side branch bus container and a connecting portion to be connected to a receiving side branch bus container are provided on a circuit breaker container in an up and down relation so as to face the same direction. Any one of the transmission side branch bus container and the receiving side branch bus container is connected to the connecting portion positioned on the upper side, and the other is connected to the connecting portion positioned on the lower side, and a transmission side power cable terminal container or a receiving side power cable terminal container is arranged at a position deviated horizontally from the axis of the transmission side branch bus container or the receiving side branch bus container.

Switchgear

In order to realize reduction of a gas insulated switchgear, a connection bus for connecting potential current transformer units, a first connecting unit, power receiving units and transformer connecting units or for connecting the potential current transformer unit, a bypass unit, a first connecting unit, the power receiving units and transformer connecting units is arranged horizontally to a connecting unit and in parallel thereto. Thereby height dimensions of the transformer connecting units, potential current transformer units and transformer connecting units can be made small and thus a height dimension of the entire apparatus can be made small.
