摘　　要：在电火花震源研制过程中,主回路开关是否能够稳定的触发导通是其中整个系统最关键的部分。采用真空触发管作为震源放电开关,本文基于真空触发管研制了一台能够稳定触发真空触发管导通的脉冲触发源。设计了直接触发和间接触发两种触发回路,进行了触发管导通试验验证以及波形采集。结果表明:触发源的触发能量对触发管的导通情况有很大的影响,研制的直接触发源可以使真空触发管稳定导通,该触发源的成功研制也将极大推动后续研究的顺利开展。In the development process of the spark source,whether the main circuit switch can stably trigger the conduction is the most critical part of the whole system.A vacuum trigger tube is used as the source discharge switch.Based on the vacuum trigger tube,a pulse trigger source capable of stably triggering the vacuum trigger tube conduction is developed.Two trigger loops:direct trigger and indirect trigger are designed,and the trigger tube conduction experiment verification and waveform acquisition are performed.The results show that the trigger energy of the trigger source has a great influence on the conduction of the trigger tube.The developed direct trigger source can make the vacuum trigger tube stably conduct.The successful development of this trigger source will also greatly promote the smooth development of follow-up research.
