【Abstract】 In this paper, some experimental results of long-gap triggered vacuum switch(TVS) are presented, including the switching-on process, triggering reliability and time-delay of triggering, and its working stability. The experimental results indicate that the high triggering reliability can be gained using the trigger circuit based on high voltage-small current first and low voltage-large current subsequently. The long gap TVS also has high working stability. Besides higher working voltage obtained from long-gap TVS, it can be used such as in the study of long vacuum arc too.更多还原
