PROBLEM TO BE SOLVED: To detect the sure actuation of an interlock and, at the same time, to make the maintenance and inspection works of the interlock easier by attaching coils for interlock which drive interlock levers for inhibiting the movement of a drawer type switchgear, the interlock levers, and stoppers to common frames. SOLUTION: Coils 1 for interlock, interlock levers 3, and stoppers 5 which are engaged with the levers 3 are attached to common frames 10A and 10B. In addition, a switch 9 is attached to the frame 10A. When the levers 3 are actuated, the switch 9 is actuated to detect that the levers 3 are driven and, because of the detecting signal of the switch 9, electrical interlock becomes possible. Since the levers 3, the stoppers 5, the coils 1, and the switch 9 are attached to the frames 10A and 10B, the assemblage and attachment/detachment of the interlock become easier, and complicatedness can be eliminated in performing an assembling work and an inspecting work of the interlock. |
