Analysis on closing bounce of vacuum circuit breaker

摘要

First of all, based on the structure of vacuum breaker, the closing bounce model of vacuum circuit breaker is established. Several factors are analyzed with the help of the numerical computing software MATLAB to determine how these factors influence bounce time of moving-contact. Reducing closing speed is a good way to reduce bounce time of moving-contact. Secondly, according to SolidWorks and ADAMS software, a method is found to not only reduce bounce time of moving-contact but also ensure closing successfully. Thirdly, the result of experiment is proved that author's view is correct and helpful.
