| 摘 要： | 采用单间隙伪火花放电装置,研究了纳秒脉冲下气压、间隙距离和小孔直径对伪火花放电特性的影响。研究结果表明,纳秒脉冲下伪火花放电电压随着气压、间隙距离和小孔直径的增加而减小。通过数值拟合,得到了放电电压与气压、间隙距离和小孔直径间的经验公式。放电电压随着气压、间隙距离和小孔直径的增加而减小,衰减系数分别为0.76,0.39和0.39。

| Abstract: | In this paper, an experimental investigation on pseudospark discharge behaviors was conducted under nanosecond pulse using a flexible discharge chamber. The influences of gas pressure, anode-cathode gap distance and hole diameter on the breakdown voltages were studied. The study results showed that the breakdown voltage decreased with the increasing of the pressure, gap distances and the hole diameter. In the end, an empirical formula was obtained. The attenuation coefficients were 0.76, 0.39 and 0.39, respectively. |
