| 摘 要： | 针对重复频率电磁脉冲（EMP）干扰，以氢闸流管的栅极触发电路为研究对象，进行了氢闸流管悬置与共地两种不同的条件下氢闸流管第一栅极与第二栅极的电磁干扰研究。结果表明，两种条件下两个栅极均存在较强烈的电磁干扰，干扰主要来源于空间电磁辐射与共地耦合两个方面；针对重复频率EMP环境下氢闸流管触发的可靠性，分别进行了不同重复频率EMP数量与不同重复频率EMP时间间隔下氢闸流管的输出实验。结果表明，两种情况均对氢闸流管的触发产生影响，重复频率EMP数量增多与间隔减小均使氢闸流管误触发的可能性增大，对比理论分析与实验结果，认为该现象是由于重复频率EMP累积效应与重复频率EMP高频分量增强从而导致交互作用耦合增强所引起。

| Abstract: | An experiment in view of repetitive frequency electromagnetic pulse (EMP) interference, take the hydrogen thyratron trigger as research object, is carried out to study the interference of the hydrogen thyratron first grid and second grid under the condition of suspension and mutual ground. The results show that the two grids have intense electromagnetic interference (EMI), and the interference is mainly caused by space electromagnetic radiation and coupling of mutual ground. The experiments are separately carried out under the EMP environment with different repetitive frequency quantity and time interval. The results show that the two cases have impact on tube trigger, increasing repetitive frequency EMP quantity and reducing EMP interval both increase the probabilities of false trigger. Comparing with the theoretical analysis and the experiment results, it is concluded that this phenomenon is caused by repetitive frequency accumulation effect and high frequency component strengthen which leads to enhanced coupling. |
