A new type controlled switching device is introduced, which based on vacuum circuit-breaker (VCB) and power electronic switch(IGBT) to form the combination switch module. The structure and working principle of provided combination switch were emphatically expounded, especially the open and closing process and controlling strategy were discussed in detail. The researched VCB with permanent magnet actuator,...
Triggered vacuum switches (TVS), have found fast growing applications in the field of power system and pulse power. The relation between triggering parameter of triggering system, such as triggering voltage and triggering power, between the trigger time delay and it s scatter of triggered vacuum switch (TVS) had been obtained through series of experiment. The result can be adopted as the steering...
The key to perform synthetic making test at full rated voltage for high voltage switches is the making device of current source, which should have the capability to withstand the static and transient voltage and also can conduct short-circuit current without excessive erosion, Moreover it ought to be hair-trigger and control accurately. A new kind of fast making device is emphatically expounded in...
