摘　　要：介绍了分路电流法放电点位置检测原理,构建了基于Lab VIEW的放电点位置检测系统,获得了电火花线切割气中精加工的放电点位置分布图。通过对常规的放电点位置分布均方差评价法的改进,证明改进后的均方差法可反映局部放电点位置分布的疏密规律及放电点位置分布随时间的变化规律。The detection principle of discharge point location detected by the branch current method was described. The detection system of discharge point location based on LabVIEW was set up. And the location distribution drawing of discharge points in the finishing process of WEDM in gas was obtained. Mean square deviation who was the conventional assessment method of discharge points distribution was improved ,which can reflect the density laws of partial discharge points distribution and laws of distribution of discharge points changes over time.
