【摘要】 本文首先简述了脉冲放电回路中三电极火花间隙的工作原理,并推导出其电阻的表达式。然后采用数值迭代法对其进行数值计算,得出间隙开关的导通电阻及其对回路电流的影响,并分析了放电过程中间隙距离、间隙气压及充电电压对间隙电阻的影响。这一研究方法对设计和分析基于火花间隙的脉冲放电回路提供了很好的评估手段。更多还原

【Abstract】 In this paper, the work principle of spark gap with three electrodes in pulsed circuit is presented briefly and then the expression of its resistance is given. The simulation research is done by the means of numerical analysis such as superposition. It is given that the resistance of spark gas and the effect posed on discharged current. The effect posed on the resistance of spark gas by distance, air pressure and charged voltage is analyzed. An excellent evaluation approach is provided for the design an analysis of pulsed circuit based on spark gap.更多还原
