Claims

[Scope of Claim for Utility Model Registration] A socket fixed to the breaker trolley that connects the control circuit wires of the circuit breaker stored in the switchboard, and a plug that connects the control circuit wires on the switchboard side to and from this socket on the front side. In a drawer-type circuit breaker, which constitutes a disconnection section of a control circuit, (a) is disposed around the periphery of this socket, is supported movably within a certain distance in the vertical direction, and is constantly pulled upward by the bias of a spring. an interlock plate having a pair of hooks in its center; (b) a pair of stop plates that engage with the pair of hooks fixed to the center of the case housing the socket; ) A lever whose one end is fixed to the lower end of the case and whose other end is tapered; and (d) a stop lever rotatably supported on the circuit breaker trolley for connecting the plug. When connecting the stop lever, one end is provided with an arcuate bent part that engages with the taper part of the lever in (c), and the other end of the stop lever, which faces the operating position of the circuit breaker, rises when connecting the plug. (e) A lock provided on the bottom of the switchboard that the other end of the stop lever that lowers comes into contact with when the plug is not connected; Plate A; and (f) a lock plate B provided on the bottom of the switchboard to prevent the interlock plate from moving downward during the movement of the circuit breaker to the operating position and the test position. An interlock device for a draw-out type circuit breaker.
