Abstract
A high-voltage power circuit breaker contains a plurality of phases which are contained in respective separate tanks which may be filled with sulfur hexafluoride. Each phase contains a respective trip-free contact operating mechanism connected to the interrupter contacts within the tank. Each of the trip-free operating mechanisms are closed simultaneously by a pneumatic closing mechanism contained in only one of the poles and connected to the other pole operating mechanisms by a common operating rod. Each of the poles are simultaneously closed by the pneumatic operating mechanism, and each pole can open independently of the other poles through its own trip-free operating mechanism.
