摘　　要：配网单相故障接地情况复杂,导致选线装置准确率低,影响供电可靠性。为提高选线装置的选线准确率分析了消弧线圈并联中电阻接地选线原理,并在实际中试用以此为原理的故障选线产品,取得了较好效果,提高了配电网运行的可靠性。The correctness of fault line selection device is very low because of the complex single-phase-to-earth fault in distribution network, which affects the reliability of power supply. Consequently, the principle of fault line selection under the are-suppression coil parallel connecting the mid-resistance grounding was analyzed ,and used in practice as the principle of fault line selection device, achieved well results, and improve the reliability of power supply.
