摘要
设计了一个两电极气体火花开关,开关的主体部分仅包括阴极、阳极两个主电极,以及金属外壳和绝缘支撑外壳,两电极结构取消了触发极,消除了由于触发极烧蚀影响开关寿命的问题。开关设计工作电压23 kV,单脉冲能量1.2 MJ,峰值电流300 kA,单次脉冲电荷转移量110 C。初步试验阶段开关工作电压达到15 kV,开关的通流180 kA,电荷转移量为47.85 C。开关触发性能可靠,电极烧蚀均匀。
A two-electrode gas spark switch is designed. It has been built for high current, large charge transfers, slight electrode erosion and long lifetime. The switch operates without a trigger electrode, reducing losses by eliminating two arc/electrode contacts. The uniform erosion of graphite minimizes pitting and roughening of the electrodes. The switch is expected to discharge a 23 kV, 1.2 MJ bank with the peak current of 300 kA and charge transfer of 110 C per pulse on a single shot. In the elementary experimental study, the switch operates at a voltage of 15 kV with reliable performance for triggering and uniform electorde erosion.
