摘　　要：提出了一种识别380 V低压配电网故障的方法。以此为基础研发了低压配电网故障智能识别系统。通过在低压配网的相应位置,如箱式变电站的低压开关、低压电缆分支箱、环网柜等设备的电缆出口处安装该智能识别系统,自动记录故障区域、故障类别、故障前后的电量有效值和相关故障波形图,供技术人员比对、分析,确定故障区域和严重程度,为准确、快速处理电网故障提供依据。This article presented a fault identification method in low voltage power distribution of 380 V. Based on it, an intelligent fault identification system in low voltage power distribution network was developed. Installed in the corresponding locations, such as cable outlets of box transformer substation＇s low voltage switcher, low voltage cable branch, and loop net cabinet. This identification system can automatically record fault area, type, the effective values before or after fault and the relative waveform figures to provide the reference for technicians＇ correct and fast handling with grids malfunctioning.
