摘要
在高功率脉冲Marx发生器中,气体开关具有连接储能器件与负载作用。文中为一种高能量输出、高频Marx发生器,设计了一种三电极场畸变气体开关。开关电极采用同轴结构,具有体积小、放电电流大和工作电压范围宽等优点;通过实验对不同气压和电极间距下场畸变气体开关电极静态特性进行了测试,实验结果表明,场畸变气体开关自击穿电压随SF6气压的增长从线性增长到非线性增长;工作电压范围随场畸变气体开关两主电极之间距离的增大而增大,最终趋于平缓;击穿电流和电压的分散性都随着工作气压的增大而增大。
In the high power pulse Marx generator,the gas switch is connected with the energy storage device and the load. This is a high energy output,high frequency Marx generator,designed a three electrode field distortion gas switch. Electrode switch using coaxial structure,with small size,large current discharge and wide range of working voltage advantages; through experiments on the static characteristic of different pressure and electrode spacing end distortion gas switch electrode were tested. Experimental results show that,field distortion gas switch breakdown voltage with the growth of the SF6 pressure from the linear growth to nonlinear growth since; operating voltage range with the field distortion gas switch between the two main electrodes distance increases and increases,eventually leveling off; breakdown voltage and current of the dispersion are with the increase of operating pressure increases.
