Abstract
The invention relates to energy storing part and switching-off and switching-on part combining device and method of a spring operating mechanism. The device comprises an energy storing part and a switching-off and switching-on part. The device has the design key point that the energy storing part and the switching-off and switching-on part are respectively two module units; and the energy storing part is connected with a switching-on crank arm of the switching-off and switching-on part and a cam by a large hexagonal shaft. In the operating method, the spring operating mechanism needs less external driving force in the process of switching-on energy storage; the stored high energy can meet the energy needed when an ultrahigh pressure alternating current vacuum circuit breaker is switched on, and is safe and reliable; and when the spring operating mechanism is in a state to be switched on and switched on, a switching-off and switching-on buckling plate has less pressure on a switching-on and switching-off half shaft, which is beneficial to releasing the switching-on and switching-off half shaft and ensures reliable switching-on and switching-off. The spring operating mechanism has the output characteristics matched with the loading characteristics of the ultrahigh pressure alternating current vacuum circuit breaker, therefore, the mechanical characteristic parameter of the ultrahigh pressure alternating current vacuum circuit breaker is met and the technical problem that the current domestic ultrahigh pressure alternating current vacuum circuit breaker is not provided with a special spring operating mechanism is solved.
