Study on glow discharge triggered repetitive frequency pseudospark switch

  • 摘要: 伪火花开关是工作在帕邢曲线左支的低气压开关,具有纳秒级击穿时间、百千安级脉冲电流、工作寿命长等特点。具有高重频性能的伪火花开关民用领域以及军事领域均有广泛的应用需求。基于双脉冲辉光放电触发结构,设计出一种具有重频能力的伪火花开关;在10 kV阳极电压下进行了整管测试,观察不同气压,预、主触发电压对重频性能以及触发性能的影响;结合仿真软件计算不同气压与触发电压下,触发电流的变化,最终总结了两个脉冲对触发过程的影响。测试结果表明,最低仅100 V触发电压,开关重复频率即可从沿面放电触发的100 Hz提升至400 Hz。
