| 摘 要： | 分析了10kV配电网中性点经小电阻接地及经自动跟踪补偿消弧线圈接地配小电流微机选线装置切除单相接地故障的可靠性和供电可靠性。通过分析比较，认为：对于全电缆配电网，宜选择中性点经小电阻接地方式；对于混合网，如果架空线所占比例较大，宜采用自动跟踪补偿消弧线圈接地配微机选线装置。

| Abstract: | In 10 kV distribution network,neutral is grounded mainly by small resistance or automatic tracking and compensating arc suppression coil with trickle micro processor based line selector.The reliability of power supply and single phase ground fault elimination of these two practices are analyzed and compared.It is concluded that the former practice is suitable for distribution network solely formed with cables,while the latter suitable for mixed network of which overhead lines account for a larger proportion. |
