摘要: 研制了一种用于快脉冲直线型脉冲变压器的±100 kV多级多通道火花开关，研究了触发电压极性、幅值对多级多通道火花开关触发性能的影响，分析了不同触发电压下开关各部分延时及抖动。研究结果表明：触发电压的极性对双极性多级多通道火花开关触发性能影响较小；开关的触发放电延时和抖动随着触发电压的增大而减小。进一步分析了多级多通道火花开关的触发击穿模式以及影响开关击穿延时和抖动的主要因素，提出了减小开关触发击穿延时及抖动的技术途径。Abstract: The mutli-gap mutli-channel spark switch is of low induance and low jitter, thus it has important application in the pulse power technology. This paper presents a ± 100 kV mutli-gap mutli-channel spark switch used for fast linear transformer driver(LTD) . The experiment studies the influence of the switch triggering breakdown characteristic of the switch with different trigger voltage polarity and different trigger voltage, then analyzes different phases delay time and jitter of the gas spark switch under different voltage. Typical results are: the influence of the switch triggering breakdown characteristic of the switch with the trigger voltage polarity is small; the delay time as well as its jitter is decreasing while the trigger voltage is increasing. The paper also analyzes the tr
