Compared with high power laboratories abroad, high voltage test level in China is to be improved. In order to meet the development requirements of modern circuit breakers and to better simulate the network, testing capabilities have to be expanded. According to the existing equipment and testing conditions of main domestic test house, a new testing circuit for synthetic making test of high voltage...
During synthetic making test a high speed making device is necessary to connect the switching device under test immediately after pre-strike during closing operation under applied voltage. A new kind of fast making device is emphatically expounded in this research, which is composed of triggered vacuum switch (TVS) and a fast vacuum circuit breaker (FVCB) with permanent magnetic actuator. Parallel-connected...
