Abstract
A switchgear comprising an electrically insulating frame having an operating mechanism accommodated at its front portion and having a main circuit accommodated at its rear portion. The insulating frame defines a space surrounded at three sides by opposing side insulating walls and a rear insulating wall arranged substantially in a U-shaped cross section. The insulating frame also supports a switch portion within the space and supports a terminal conductor leads from the switch portion extending through the rear insulating wall to project toward the rear of the switchgear. The switchgear also comprises an electrically insulating cover covering at a front side of the insulating frame at least the rear end, the top end and the opposing side ends of the operating mechanism. Also, the switchgear may comprises a face plate disposed to a front portion of the switchgear and an operating mechanism disposed between the face plate and the insulating frame. Therefore, the insulating distance between the components can be made small and no metal casing is necessary, allowing the switchgear to be small-sized and simple in structure.
