Claims (1)

[Scope of utility model registration request] The opening/closing equipment is loaded and fixed on a movable trolley,
This trolley is placed in a cradle inside the switchboard, from a position outside the switchboard to a test position where the switching equipment is tested for switching the main switch without connecting it to the main circuit of the switchboard, and then from this test position via an intermediate position. A moving mechanism that stores the switchgear in the operating position connected to the main circuit of the switchboard, and conversely pulls it out from the operating position to a position outside the switchboard via an intermediate position and a test position, and the conditions for this moving operation. In the movable interlock device for opening/closing equipment, which is equipped with a regulating interlock mechanism, the movable mechanism, the interlock mechanism, and the guide plate are integrally provided on a base fixed on the bottom plate of the cradle, and An interlock pin that is movably supported, whose upper end moves in and out between the electromagnet and the movable iron piece that drives the operating shaft for opening and closing the main switch, and whose lower end abuts and engages with the guide plate, and a removable interlock pin. A moving mechanism that engages with the drawer handle and rotates the drawer shaft to move the engaged cart, and an interlock cover that restricts the insertion of the drawer handle is fixed to one end and rotatably supported. an interlock shaft that moves up and down in conjunction with the rotation of the interlock shaft, and an interlock rod that lifts and disengages the interlock pin that is engaged with the guide plate at the test position and operating position of the opening/closing device. a hole that engages the interlock pin between the test position and the operating position of the switching device; and a slope that moves the interlock pin in the vertical direction between the outside position of the switchboard and the test position. A movable interlock device for opening/closing equipment, comprising: and a guide plate having a flat part for keeping the interlock pin in a raised position at an intermediate position.
