Switchgear assembly for electrical apparatus

Abstract

A switchgear assembly for an electrical apparatus capable of improving operability thereof to a practical extent, as well as reducing not only installation area or space for various devices to be disposed below the switchgear but also the weight of the switchgear itself. The switchgear assembly such as a disconnecting switch assembly, fuse assembly or the like is interposed between a bus bar supported through a first support insulator on the top end of a vertical pole, and an electrical apparatus connected to the bus bar. The disconnecting switch assembly or fuse assembly comprises a movable contact pivoted at its one (lower) end to a pole mounted second support insulator for rotary motion in a vertical plane and engageable at the other (upper) end directly with the bus bar or with a fixed contact or fuse retainer supported on the bus bar by a fastening member. The other (upper) end of the movable contact or fuse is fastened to the bus bar completely independent of the pole. The movable contact may be a fuse with retainers at opposite ends.
