MECHANICAL INTERLOCK STRUCTURE FOR SWITCHGEAR

摘要

An interlock structure is coupled between actuating structure and a travel adjuster of a circuit breaker. The interlock structure includes a body having a bore therein. An engaging member has a portion sized to be received by the bore and the engaging member is coupled with the travel adjuster for movement therewith. A slide member is movable with respect to the body between operative and inoperative positions. Linkage structure is coupled to the slide member for moving the slide member and is also coupled to the actuating structure such that upon movement of the actuating structure, the linkage structure moves the slide member to the operative position so that the slide member blocks at least a portion of the bore to prevent the engaging member from entering the bore and thus prevents the travel adjuster from moving in a certain direction to allow the closure of the circuit breaker contacts.

主权项

1. A circuit breaker comprising:
a circuit breaker module including contacts and a travel adjuster associated with the contacts such that when the circuit breaker module effects a closing position, the travel adjuster moves in a certain direction to permit the contacts to close, interlock structure coupled with the travel adjuster and having an engaging member that moves with the travel adjuster, the interlock structure further including a slide member and linkage structure, the linkage structure being constructed and arranged to move the slide member between operative and inoperative positions, and actuating structure coupled with the linkage structure and constructed and arranged to move the linkage structure and thus the slide member 1) to the operative position to prevent the engaging member and thus the travel adjuster from moving in the certain direction to prevent closure of the contacts, and 2) to the inoperative position to permit the engaging member and thus the travel adjuster to move in the certain direction to enable closure of the contacts.
