Claims

[Claims for Utility Model Registration] (1) A support stand, an operating mechanism installed on the support stand and having an operating rod protruding vertically upward, and an operating mechanism that is installed upright on the support stand alongside the operation mechanism. a box-shaped support frame, a vacuum switch installed vertically for each phase via a support insulator on the lower side portion of the box-shaped support frame that is in close contact with the support base, and a vacuum switch for each phase. An insulating rod extends vertically upward from a movable electrode rod at the upper end of the switch, one end is attached to the insulating rod for each phase, the other end is attached to the operating rod, and the middle part is individually connected to the box. A vacuum switching device comprising: an operating lever rotatably supported on an upper side portion of a box-shaped support frame; and an external connection terminal of the vacuum switch supported by the box-shaped support frame via an insulator. (2) A vacuum switchgear according to claim 1 of the utility model registration claim, characterized in that a box-shaped support frame is formed in common for all phase vacuum switches. . (3) A vacuum switchgear according to claim 1 or 2 of the utility model registration, characterized in that the box-shaped support frame has substantially trapezoidal sides.
