Non-rotary, pull-pull interphase gang-style linkage structure for high voltage dead tank breaker

Abstract

Linkage structure is provided for connection between an operating mechanism and at least one actuating assembly of a circuit breaker for opening and closing a movable electrical contact of a pole assembly associated with the actuating assembly. The linkage structure includes at least one lever constructed and arranged to connect with the at least one actuating assembly. At least one connection rod is coupled to the lever and associated with a close spring for closing the electrical contact. At least one spring structure is coupled to the lever. The spring structure includes at least one open spring providing a spring force on the lever for opening the electrical contact while maintaining the connection rod in tension.

Dependencies are inferred from the claim text.
