ABSTRACT:
A gas insulated switchgear apparatus comprising connection conductors connected to a connection portion to breaker side, disconnectors connected to the connection conductors, cable heads connected to the disconnectors, lightning arresters having one end connected between the disconnectors and the cable heads, single phase voltage transformers provided in one of three phases and having one end connected between the disconnectors and the cable heads and a disconnector cylindrical vessel filled with an insulating gas and containing the connection conductors, the disconnectors, the cable heads, the lightning arresters and the single phase voltage transformers therein. The cable heads are disposed so that the axis of the disconnector cylindrical vessel and the axes of the cable heads are parallel. The lightning arresters are disposed so that the axis of the disconnector cylindrical vessel and the axes of the lightning arresters are parallel. The disconnectors are disposed within a space between the cable heads and the lightning arresters, the connection portion is disposed on a side of one end portion of the disconnector cylindrical vessel and the single phase voltage transformers are disposed on a side of the other end portion of the disconnector cylindrical vessel.
