Abstract

A switchgear having vacuum valves, an interrupter operating mechanism and a ground switch operating mechanism, the latter two being disposed on a metal common base frame. The interrupter operating mechanism comprises a drive shaft that extends on a line of direction of opening and dosing movements of a contact electrode of the vacuum valve, whereby a drive load is directly transmitted to the contact of the vacuum valve along the line of direction. The drive shaft of the interrupter operating mechanism is disposed on the common base frame at a section between movable rods and is connected to the drive shaft through a connecting member. A connecting member and a spring rod of a ground switch side movable rod of the ground switch operating mechanism are connected through a wipe-link mechanism. <IMAGE>
