激光诱导间隙放电效果的试验研究

Testing Study of Gap Flashover Trisgered by Laser-plasma

对影响激光诱导放电效果的诸多因素如激光参数、电场分布、电场作用时间、大气条件进行了试验研究。结果表明，与正极性比较，激光更易于触发负极性电压气隙放电。激光束与高压电极轴线间夹角也影响放电电压的大小。

This paper studies main factors that influenceflashover voltage triggered by laser plasma by using modelexperiment. The main factors include laser energy, electricfield distribution along the laser beam, electric field period,air condtion. The results indicate that the nagative voltageis triggered by laser more castly than positive voltage anddegree of an angle between laser beam and high voltage electrode axis can influence the flashover voltage triggered bylaser plasma.
