摘要/Abstract

摘要： 针对强电磁场诱发静电放电问题,研究金属电极结构静电放电延迟时间,进一步探索强电磁场作用下金属电极静电放电变化规律。从电磁场诱发静电放电通道形成过程和放电机理出发，重点分析了强电磁脉冲辐射下诱发金属静电放电规律。试验结果表明：在强电磁脉冲辐射场作用下，辐射场强增强会使诱发放电的时延缩短；随着金属电极间电压升高，极间场强增大，能够缩短诱发放电延迟时间；随着气压的升高，分子间距缩小，同样能够缩短放电延迟时间。

Abstract: For the problem about electrostatic discharge induced by strength electromagnetic field, the delay time of electrostatic discharge of metal electrode is studied to further explore the changing law of its electrostatic discharge under the action of strong electromagnetic field. The electrostatic discharge rule of metal electrode under the action of strong electromagnetic field is emphatically analyzed from the formation process of discharge channel and the mechanism of electrostatic discharge induced by electromagnetic field. The test results show that enhancement in the magniude of radiated field strnegth results in the shorted delay time of induced discharge under the action of strong electromagnetic pulse radiation field, and the voltage between metal electrodes and the air pressure all have impact on the delay time of induced discharge under the action of strong electromagnetic pulse. The delay time of induced discharge gradually shortens and the dispersion of time delay also becomes gradually smaller with the increase in metal electrode voltage, radiated field strength or air pressure.

Key words: strongelectromagneticfield, electrostaticdischarge, strongelectromagneticpulseradiation, induction, delaytime
