| 摘 要： | 为解决架空输电线路雷击事故频发的问题,一种安装于架空输电线路上的喷射气体灭弧防雷间隙装置得到了开发和应用。当输电线路遭受雷击,雷电冲击电流击穿间隙,导致工频续流时,该装置能够迅速切断间隙两端电弧,有效保护绝缘子串免受工频电弧灼烧。依据现有电弧理论方程模型,运用ANSYS 10.0软件对高速气流和电弧进行仿真计算,同时利用高速摄像机和示波器观测电弧电流的变化过程。试验结果表明间隙电弧在高速气流作用之下能够快速熄灭。

| Abstract: | To address the problem of frequent linghtning strike incidence occurred on overhead transmission lines,a kind of jet stream interrupter gap lightning protection device(JSGLPD),which is installed on overhead transmission line,is developed and applied.When transmission line is lightning-struck,the lightning surge breaks down the gap and cause power frequency afterflow,right now the JSGLPD can quickly cut off the arc at both ends of the gap and effectively prevents the insulator string from sparkwear by power ... |
