| 摘 要： | 搭建了空气中脉冲电压下激光触发沿面闪络试验平台,在试验平台上进行了尼龙介质的激光触发沿面闪络特性试验,应用蒙特卡罗方法对尼龙在空气中激光触发沿面闪络过程进行仿真。建立了激光触发沿面闪络的蒙特卡罗仿真模型,对蒙特卡罗算法的实现过程进行了描述,得出激光能量密度不同时的闪络时延。仿真结果显示,随着激光能量密度的上升,激光触发沿面闪络时延下降,这表示激光能量密度增加,在介质表面上产生的电子数增多,使沿面闪络的时延减小,仿真结果与试验结果趋势一致,初步验证了空气中脉冲电压下激光触发沿面闪络机理。

| Abstract: | The experimental platform of laser-triggered surface flashover in pulsed voltage has been built up in the laboratory,and then the experiment of laser-triggered surface flashover was carried out using nylon columned insulators.On this basis,the laser-triggered surface flashover of nylon was simulated by Monte Carlo method,and the delay time of flashover was obtained with different laser energy densities.The simulation result shows that delay time decreases with laser energy density increasing,indicating an i... |
