摘　　要：介绍一种正负极性工作、无需热丝供电配套的伪火花开关,其触发方式可以采用电触发、空间激光触发以及光纤传输激光能量触发。在电触发模式下开关技术指标达到工作电压±60 kV、脉冲电流16.2 kA以及抖动7 ns;空间光触发模式下,开关抖动3 ns(1 mJ/532 nm),最低触发激光能量0.15 mJ;光纤传输激光能量触发工况下(光纤入射端能量7 mJ/出射端5 mJ/532 nm),开关抖动技术指标达到3 ns。This paper introduces a pseudo-spark switch which works in positive and negative polarity and does not need hot wire power supply.It can be triggered by one of the three modes of electric triggering,space light and fiber transmission laser energy.In the electric trigger mode,the technical specifications of the switch reach the operating voltage±60 kV,the pulse current16.2 kA and the close jitter 7 ns;In space light trigger mode,the close jitter is 3 ns using 1 mJ/532 nm laser,and the minimum triggering laser energy is 0.15 mJ.In the fiber transmission laser energy mode(the energy of the incident end of the fiber is 7 mJ/the output end is 5 mJ),the close jitter is 3 ns.
