摘要
Abstract
The CT20 spring operating mechanism is widely used in 126 kV voltage level circuit breakers because of its series of advantages.This type mechanism may not meet the requirement of higher interrupting capacity circuit breaker while the interrupting capacity is increasing.If the corresponding measures are not taken,the vibration of the closing latch during the closing of the mechanism may result in the failure of the closing operation.In view of this problem,the vibration of the closing latch during closing is chosen as the research point.First,the closing process is analyzed by simulation software.Then the vibration of the closing latch is recorded by the high speed camera.Finally the effect on closing perform caused by the vibration of the closing latch is analyzed and the research result is summarized.The method of reducing the vibration of the closing latch is proposed.From this paper some conclusion can be got:The vibration time of closing latch always continue 10 ms which is the key of closing keep process.The amphtude coefficient of the bigger closing latch is 7.6％ with that of the smaller one is 28.6％.Closing keep process may fail while amplitude is too big or vibration time is too long.关键词
