摘　　要：在新的强激光能源系统中,采用了一种大电荷转移量同轴结构的两电极气体开关。为了研究气体开关的开通过程,采用仿真软件ATP与PSCAD分别对该开关在开通过程中的某些特征参量对开通特性的影响进行了仿真分析和研究,提出了一种用于模拟气体开关开通过程的模型,并由此得到了触发电压与导通能量之间的关系曲线,并从中得出结论,触发能量对气体开关导通的影响不大。The high-coulomb two-electrode coaxial spark gap switch should be one of the better switching solutions in the power conditioning system for high power lasers.The turn-on process of this spark gap switch is studied with software ATP and PSCAD.The influences of several parameters on the turn-on characteristics are simulated and analysed,and then an electrical parameter model of the turn-on process is proposed.Based on this model,the relation between trigger voltage and turn-on energy is obtained in the resulting curve,which shows that trigger energy does not significantly affect the turn on of this switch.
