摘要
Abstract
CT20 spring operating mechanisms have been widely equipped to 126 kV HV circuit breakers, which run reliably and are well evaluated. Because of many excellences, the spring operating mechanism is now applied to 252 kV or higher HV circuit breakers. The article analyses the CT20 spring operating mechanism, and adopts the mechanical dynamic simulation analysis software ADAMS to conduct the simulative calculation. The calculation'results indicate that the structure of the CT20 spring operating mechanism must be improved in order to increase its operating power and the reliability. The structure of a CT20 spring operating mechanism is improved for increasing the operating power by about 40%, and the prototype behaves satisfactorily in the service-life test.关键词
