| 摘 要： | 针对一种用于快前沿直线脉冲变压器驱动源的多间隙气体开关，设计了针式和孔式两种预电离触发结构，获得了两种预电离结构下开关的自击穿特性和触发特性。实验结果表明:增加预电离针后，开关静态特性没有明显变化，开关自击穿电压平均值变化幅度小于3%;开关触发特性明显改善，开关工作电压150 kV、触发电压60 kV时，触发抖动减小约20%，触发阈值降低5~10 kV。对于针式预电离结构，实验研究了不同触发电压、工作气压、电离间隙距离时紫外光强度的变化规律,结果表明在电离间隙距离1.5~3.0 mm时，开关触发抖动小于2.0 ns，预电离效果明显。

| Abstract: | This paper summarizes the structural design and experimental study of UV pre-ionizing for multi-gap gas switch.The structures of needle UV pre-ionizing and hole UV pre-ionizing are designed.Static properties of switches with three trigger structures are obtained.There is no evident change of static field in switches and the change of self-breakdown voltage is under 3% with UV pre-ionizing.The jitter of UV pre-ionizing switches is about 20% less than that of the switch without UV pre-ionizing.The needle UV p... |
