通过将冲击片雷管（ｓｌａｐｐｅｒｄｅｔｏｎａｔｏｒ）起爆电路表示成为ＬＲＣ电路，对高压开关的电阻、电感的变化规律及其对起爆电流的影响进行了研究。从幅值、时延两方面考虑开关的闭合特性，讨论了几种不同特性的开关对电流的影响。分析结果表明：应保证开关具有低阻值、短时延的阻性闭合特性和低感值、长时延的感性闭合特性以减少高压开关对电路电流起爆的影响，从而保证冲击片雷管的可靠作用。
The impact of the slapperdetonator detonation circuit on the LRC circuit is studied. The variation of the resistance and inductance of the high voltage switch and its influence on the detonation current are studied. Considering the closing characteristics of the switch from two aspects of amplitude and delay, the influence of several different characteristics on the current is discussed. The analysis results show that the switch should have low resistance, short-time resistive closed characteristic and low inductance, long-time inductive closed characteristic to reduce the influence of high-voltage switch on the circuit current detonation, so as to ensure the reliability of the impulse detonator effect.
