摘要: 气体火花开关在重复频率脉冲功率技术中具有广泛的应用,影响气体火花开关绝缘恢复与重复频率工作性能的因素众多。实验研究了气体火花开关的能量沉积和气压对开关重复频率指标的影响,给出了气体火花开关绝缘恢复时间与气压及开关导通功率的关系式,初步分析了气体开关击穿通道在自然散热(不吹气)条件下,重复频率稳定工作的最高功率与重复频率指标、气压的关系。Abstract: Gas spark switch has been widely used in repetition rate pulsed power technology. Insulation recovery and repetition rate of gas spark switch are affected by many factors. The influences of gas spark switch energy deposition and pressure on the repetition rate were experimentally studied. The relationships between insulation recovery time of gas spark switch, air pressure and switch power were put forward. The relationships between switch power, repetition rate and pressure were preliminarily analyzed on the condition that the gas switch breakdown channels was cooled in natural convection.
