Claims

[Scope of utility model registration request]

A power switchgear which is housed in a compartment and has a disconnection section that disconnects or connects the main circuit by being pulled out or pushed in on a trolley, and the load side of this switchgear via the above-mentioned disconnection section. and a grounding switch connected to the ground switch and housed in another compartment across a partition plate, one end of which is in contact with an end of the cart on the partition plate side, and the other end of which is attached to the partition plate. an interlock rod that extends through the grounding guide toward the earthing switch and has an interlock groove in the middle; and a spring that is attached to an interlock shaft provided on the switch and is biased in the moving direction of the trolley. an interlock lever that presses the lock rod; an interlock hinge that is rotatably attached to the partition plate and whose tip is inserted into the groove to prevent movement of the cart; and this hinge and the earthing switch. and a connecting wire that connects the grounding switch with a buffer spring so that the tip of the hinge is inserted into the groove when the earthing switch is closed.
