三相供电线路的漏电流分布规律

The distribution law of leakage current in three-phase supply lines

面对安全用电的严峻形式 ,经国内外的实践证明 ,安装使用漏电保护开关对于防止触电身亡 ,避免设备接触地故障损坏和漏电引起火灾事故 ,及减少漏电引起的电能损耗 ,具有明显效果。然而对于漏电保护开关的跳闸临界值具有很大歧义 ,因此我们首先对漏电流进行分布拟合 ,将得出的参数值进行随机模拟 。

Today how to use electricity safely still faces serious problems. Proved by domestic and overseas practice, the installation and use of protecting switch of leakage of electricity is obviously effective in preventing casualties from getting electric shocks, avoiding damage to ground equipment and fire accident caused by leakage of electricity, and decreasing loss of electricity because of its leakage.However, there are many different interpretations to the critical value of tripping operation of the protection switch, hence we make distribution fit to the leaked electricity, and make random simulation with the parameter values that we get, thus the critical value of tripping operation of protecting switch of leakage of electricity is determined.
