Abstract

Dynamic breakdown of ammonium perchlorate single crystals is numerically simulated. A system of differential equations that describe processes in an equivalent circuit of a pulsed voltage oscillator, a kinetic equation of impact multiplication of electrons, and a heat-balance equation are simultaneously solved. The breakdown strength of ammonium perchlorate is calculated in the dynamic mode versus interelectrode distance and leading edge of a high-voltage pulse. The calculated results are in reasonable agreement with the experimental data on the dynamic breakdown of ammonium perchlorate.

高氯酸铵单晶动态击穿的模拟

摘要

数值模拟了高氯酸铵单晶的动态击穿。同时解决了描述脉冲电压振荡器等效电路中的过程的微分方程系统，电子的冲击倍增动力学方程和热平衡方程。在动态模式下计算高氯酸铵的击穿强度与电极间距离和高压脉冲的前沿之间的关系。计算结果与高氯酸铵动态分解的实验数据基本吻合。
