摘　　要：为了研究电磁脉冲(EMP)传导干扰对开关触发系统可靠性的影响,以氢闸流管栅极触发电路为研究对象,建立了共地耦合干扰模型,进行了栅极共地耦合电磁干扰研究和重复频率EMP环境下的实验。结果表明,重复频率电磁脉冲传导干扰对触发系统产生影响,重复频率EMP数量增多与间隔减小均使误触发的可能性增大,对比理论分析与实验结果,认为该现象是由重复频率电磁脉冲传导干扰的累积效应和高频分量增强导致交互作用耦合增强引起的。In order to analyse the impact of the conducted interference of electromagnetic pulse （EMP） on the switch trigger system reliability, taking the hydrogen thyristor trigger as research object, a common ground coupling model is carried out to research the interference of the hydrogen thyristor grid under the mutual ground and experiments are carried out under the EMP environment. The results show that the conducted interference of electromagnetic pulse has impact on the tube output. Increasing repetitive frequency EMP quantity and reducing EMP interval can both increase the probabilities of the false trigger. Comparition of the theoretical analysis and the experiment results shows that this phenomenon is caused by the enhanced interaction coupling due to the conducted interference accumulation effect of the repetitive frequency and the high frequency component strengthen.
