Spring operating mechanism of circuit breaker

The invention discloses a spring operating mechanism of a circuit breaker, which is characterized in that an opening frame is arranged on the rear end surface of a closing frame, an energy storage shaft arranged in the closing frame drives a closing spring arranged in the closing frame, the energy storage shaft drives an output shaft arranged in the closing frame to rotate, and the output shaft is linked with a transmission shaft in the opening frame; and the transmission shaft drives an opening spring arranged on the opening frame. By arranging the output connecting lever, the middle item connecting rod and the middle item output connecting lever, linkage of the output shaft and the transmission shaft is achieved, linkage is formed in the switching-on process and the switching-off process, split driving parts in the prior art are omitted, and the overall size is reduced. 本发明公开了一种断路器的弹簧操动机构，所述合闸框架后端面设置分闸框架，在合闸框架内设置的储能轴驱动合闸框架设置的合闸弹簧，储能轴驱动合闸框架内设置的输出轴转动，输出轴与分闸框架内的传动轴联动，该传动轴驱动分闸框架设置的分闸弹簧。本发明通过设置输出拐臂、中项连杆和中项输出拐臂，实
