... 11TR04219 An operating device for an electric circuit breaker comprises a closing spring and a rotatable springcontroller mounted for rotation between first and second dead-center positions with respect to the spring. The spring is charged by transmitting rotational forces to the spring-controller through a main pawl mounted on the springcontroller and an abutment on a rotatable driving member. The main pawl is released from driven engagement with the abutment at the end of a spring-charging operation. Normal circuit-breaker closing is affected by allowing the spring to quickly discharge after a charging operation. A manual slow-close operation of the circuit breaker is effected through an auxiliary pawl mounted on the spring-controller in a position angularly-spaced from the main pawl.

In addition, when the short-circuit accident current occurs, the contact force of the mover is kept constant within a range smaller than the current limiting force due to the electromagnetic repulsion force, thereby maintaining a structure in which the mover is kept away from the stator after the instantaneous electromagnetic repulsion force is generated. This shortens the breaking time of the short circuit fault current, solves a structural problem in which the breaking failure and the contact are fused, and increases the breaking capacity of the circuit breaker. 배선용 차단기, 한류기구장치, 캠, 샤프트, 접촉스프링 Circuit breaker, current-limiting device, cam, shaft, contact spring
