Abstract
A gas insulated power switch gear apparatus of a reduced height comprising gas insulated circuit breakers arranged horizontally and disconnecting switches operated vertically is disclosed. Each of the disconnecting switches includes a first sheath portion inserted into an interrupted point of a main bus bar and mechanically connected with the sheath of the main bus bar through an insulating spacer for defining a gas section, and a second sheath portion communicating with the first sheath portion and crossing and extending in the direction perpendicular to the first sheath portion. A collector electrically connected with the conductor of a feeding bus bar is arranged within the second sheath portion, and a movable contactor normally electrically connected with the collector is movable vertically. A fixed contactor electrically connected with the main bus bar conductor and engageable with the movable contactor is arranged within the first sheath portion.
