Abstract
The utility model relates to a combined device of an energy storage part and an opening and closing part of a spring operating mechanism, consisting of the energy storage part and the opening and closing part. The design points are as follows: the energy storage part and the opening and closing part are respectively two module units; and the energy storage part is connected with a crank and a cam of the opening and closing part by a large hexagonal shaft. The external driving power needed in the closing energy storage process of the spring operating mechanism is less, the stored high energy can meet the energy needed when an ultrahigh-voltage alternating-current vacuum circuit breaker is closed so as to achieve safety and reliability; in addition, when the spring operating mechanism is in state to be opened and closed, a closing and opening fastening plate has less pressure on a closing and opening semi-shaft so as to be beneficial to tripping of the closing and opening semi-shaft and ensure reliable closing and opening. The output characteristic of the spring operating mechanism is matched with a load characteristic of the ultrahigh-voltage alternating-current vacuum circuit breaker, so that the mechanical characteristic parameter of the ultrahigh-voltage alternating-current vacuum circuit breaker is met, and the technical difficulty of no special spring operating mechanism in the current domestic ultrahigh-voltage alternating-current vacuum circuit breaker is solved.
