摘要：A circuit breaker arrangement includes at least one pole part for switching an electrical medium to high voltage circuit by a respective pair of fixed and movable electrical contacts. A pushrod of a respective movable electrical contact is operated by a common actuator unit, which is mechanically connected to each pushrod via a transmission mechanism for transferring a switching force from the actuator unit to each pushrod. The transmission mechanism includes a crankshaft having at least one crank which is pivotally attached to one end of a connection rod. An opposite end of the connection rod is pivotally attached to an end of the pushrod of a corresponding pole part.

主权项：1. A circuit breaker arrangement comprising: at least one pole part configured to switch an electrical medium to high voltage circuit by a respective pair of a fixed electrical contact and a movable electrical contact; at least one pushrod configured to move a corresponding movable electrical contact of the at least one of pole part, respectively; a common actuator unit configured to operate each pushrod; and a transmission means for transferring a switching force from the actuator unit to each pushrod, the transmission means mechanically connecting the actuator unit to each pushrod, wherein the transmission means includes a crankshaft having at least one crank and at least one connection rod, the at least one crank being pivotally attached to a first end of a corresponding one of the at least one connection rod, wherein a second end of the corresponding one of the at least one connection rod opposite to the first end is pivotally attached to an end of a corresponding one of the at least one pushrod of a corresponding one of the at least one pole part to move the corresponding pushrod, wherein three pole parts are arranged in parallel one to another in a line formation corresponding with the crankshaft of the transmission means, and wherein the crankshaft is common to each pole part.
