摘要
研究了200kV激光触发多级多通道开关的运行机理,该开关在直流电压下以四倍频Nd:YAG激光器为触发源进行的实验结果表明:开关触发延迟时间及其抖动随开关电压、激光能量和充气压力上升呈指数下降趋势,对混合气体则随气体密度上升而上升。随透镜焦距的增大延迟时间及其抖动呈上升趋势。该开关实现了多通道放电。
This paper reported the design and experimental results of a 200kV laser triggered multistage and multichannel switch. When a quadruple Nd:YAG laser set was used as a trigger source, it was found that the delay decreased exponentially as the charging voltage, pressure or the energy of laser pulse increased when N2 was filled in gaps. The delay increased as the density of SF6N2 mixtures increased and as the focal length of lens increased for N2, but it is not obvious for SF6N2 mixture. The discharging phenomenon of multichannel was observed.
