摘　　要：小电阻接地配网出现断线故障,当断线偏离导电设备,常规保护则将由于无法测出高阻接地能力无法达到动作条件,也就难以排查故障,进而威胁配网系统安全。对此则需要深入剖析小电阻接地系统断线模式下电压与电流特点,并针对性地提出断线保护对策和措施。When the wire break fault occurs in the low resistance grounding distribution network, when the wire break deviates from the conductive equipment, the conventional protection will be unable to measure the high resistance grounding capacity and can not reach the operating conditions, so it will be difficult to troubleshoot the fault, thus threatening the safety of the distribution network system. Therefore, it is necessary to analyze the characteristics of voltage and current in the wire-breaking mode of the small resistance grounding system, and put forward the countermeasures and measures of wire-breaking protection.
