Abstract:In recent years, pulse power technology is developing towards the goal of high working frequency. One of the key technologies involved is the development of high power repetitive short-circuit transition switches. The triggered vacuum switch (TVS) is promising in this field because of the excellent dielectric strength recovery property of vacuum. However, the high frequency current interruption ability and vacuum dielectric strength recovery characteristic of TVS with common electrode structure have not been known. In this paper, the TVS is tested under five different high oscillating frequencies. The results show that restrike time contains strong randomness. The restrike probability is increasing with the increase of rate of current change when it passes zero. And with the increase of oscillating frequency, the interruption ability of TVS becomes weak. All these will help the development of high power repetitive short-circuit transition switches.
