Abstract:
A circuit breaker comprising spaced-apart, high voltage enclosures respectively mounted atop spaced-apart insulators, circuit interrupters within the enclosures, and control valves respectively associated with the interrupters for controlling their operation. The control valves are interconnected by a mechanical linkage for simultaneously operating the control valves. The linkage comprises a force-equalizing coupling, the parts of which can change position slightly in response to minor shifting of one enclosure relative to another without imparting motion through said linkage to any of said control valves.
