摘要气体触发开关是脉冲功率电路的重要组成器件。针对工程中对低抖动、长寿命气体触发开关的需求,结合三电极场畸变型触发开关,设计一种拥有较多孔隙的多环型触发极结构。对三种主电极-触发极分别为平板-多环、平板-圆盘、球冠-圆盘的开关进行击穿特性实验研究,结合电场仿真对比分析实验结果。实验结果表明：在22.4kV/40ns的触发脉冲和5.0~7.5kV的工作电压下,平板-多环结构的开关时延及抖动比较稳定,开关时延基本在81.0~84.5ns之间,抖动为0.8~1.1ns。平板-多环电极结构开关时延、抖动均明显优于平板-圆盘结构,其开关时延、抖动与球冠-圆盘结构基本相同但使用寿命优于球冠-圆盘结构。

Abstract：Gas triggered switches are important components in pulse power circuit. For the requirements of low-jitter and long working-life triggered gas switches in actual conditions, the polycyclic type trigger electrodes with multiple pores are designed, combined with the field distortion trigger switch of three electrodes. The breakdown characteristics of trigger switches are tested, where the structures of main-trigger electrodes are flat-polycyclic, flat-disk, and spherical-disk. The test results are compared with electric field simulation results. It is proved that, under 22.4kV/40ns triggering pulse and 5.0~7.5kV loading voltage, the switching time and jitter of flat-polycyclic type switch are more stable. The switching time delay of flat-polycyclic type switch is between 81.0~84.5ns, and the switching jitter is 0.8~1.1ns. Regarding the switching time and jitter, the flat- polycyclic type switch shows better performance than flat-disk type switch, and it is similar as spherical-disk type switch but its working life is longer than spherical-disk type switch.

Key words： Gas switch structure trigger operating life time delay
