| 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。

| Abstract: | 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. |
