摘要：
Triggering characteristics of triggered vacuum switch (TVS),including the dischargedelay time,delay jitter,range of operational voltage and peak of pulsed current,are investigated.Both structure and experimental circuit of TVS are presented.The results indicate that TVS,asa surface flashover triggering device with high dielectric permittivity material,is with excellenttriggering characteristics.When the hold-off voltage reaches 120 kV,the minimum operationalvoltage is 1.3 kV,and the minimum discharge delay time and jitter are 100 ns and ±10 ns,respectively.The peak current is up to 240 kA when the operational voltage reaches 100 kV.TVScan well satisfy the main demands of high voltage and current applications,and can also be usedunder a multi-crowbar circuit.
