摘要

脉冲功率技术在大功率激光、Z箍缩、高功率微波和材料合成等领域均有非常广泛的应用

气体开关是脉冲功率装置中关键元件之一。为了获得开关间隙中不同气体电介质时开关工作性能、开关寿命等的变化规律

笔者针对一种典型结构的场畸变气体开关

采用工程中常用的正负充压回路方式

通过改变SF6/N2、SF6/Ar混合比、气压和电极间距等实验参数

详细分析了其对开关自击穿电压、放电通道等放电特性的影响规律

为多通道场畸变开关的设计提供依据。

Abstract

The pulsed power technology is widely used in the field of high power laser

z-pinch

high power microwave

and material synthesis.Gas switch is one of key part in pulsed power technology.In this paper

a field distortion gas switch was selected for the experiment

and the experimental circlesele cted the mode of positive-negative charging which widely used in engineering application.For obtaining the change law about the switch performance and the switch lifetime

the discharging channel number and the discharge characteristics of the mixing gases of SF6/N2 and SF6/Ar have been investigated in different mixing rate

gas pressure and electrode gap distance.The results can be used in the design of multichannel gas spark switch.
