Title:
INTERLOCK SYSTEM FOR SWITCHGEAR
Document Type and Number:
WIPO Patent Application WO/2013/119289
Kind Code:
A3
Abstract:
An interlock system for a circuit-interrupting device. The circuit-interrupting device includes a gearbox, a load-breaker in series with a visible disconnect, and an assembly driving the visible disconnect between an open state and a closed state. The interlock system includes a cam and a bias-driven follower. The cam is coupled to a shaft and is driven by the shaft between a first cam state when the load-breaker is in an open state and a second cam state when the load-breaker is in a closed state. The bias-driven follower has a first follower state when the cam is in the first cam state and has a second follower state when the cam is in the second cam state. In the second follower state, the bias-driven follower blocks movement of at least one component of the assembly. The cam and the bias-driver follower are positioned inside the gearbox.
