Energy-storage operating mechanisms for circuit-interrupting structures alone and also for circuit-interrupting structures utilizing serially-related disconnecting-switch structures therewith

摘要

An improved operating mechanism of the energy-storage type is provided for circuit-interrupting structures, including an energy-storing means having the energy content therein increased by the movement of a movable member, during the closing operation and a collapsible toggle-linkage is provided between the energy-storing means and the separable arcing contact structure of the circuit-interrupter structure. Improved means are provided for tripping operation, and thereby effecting the collapse of said toggle-linkage to effect the opening of said separable contact structure, and a second releasing means is preferably provided for discharging the stored-energy of the energy-storing means to effect thereby the straightening of said toggle-linkage and the consequent closing of the separable contacts within the circuit-interrupter during the closing operation.
