Spring operation device of circuit breaker

A spring operation device of a circuit breaker includes a closing shaft rotating to apply closing driving force to a movable contactor of a circuit breaker; a breaking shaft connected to the closing shaft in an axial direction and rotating to apply breaking driving force to the movable contactor of a circuit breaker; a plurality of springs having one ends connected to the closing shaft and the breaking shaft and the other ends fixed in position and provided along circumferences of the closing shaft and the breaking shaft in order to transmit elastic restoring force to the closing shaft and the breaking shaft to rotate the closing shaft and the breaking shaft; and a power transmission unit connecting the closing shaft and the breaking shaft when a closing operation is performed and releasing a connection between the closing shaft and the breaking shaft when a breaking operation is performed. 本发明公开的断路器的弹簧操作装置包括：合闸轴，该合闸轴旋转以向断路器的活动接触器施加合闸驱动力；分断轴，该分断轴沿着轴向连接于所述合闸轴，并旋转以向断路器的所述活动接触器施加分断驱动力；多个弹簧，该多个弹簧的端与所述合闸轴和所述分断轴连接，
