摘　　要：以一起10 kV同塔双回线路的单回接地短路故障发展为双回相间接地短路并导致断线的复杂故障为例,从理论上分析了接地短路的电气量特征,结合录波数据及现场勘查资料分析,分析出故障演变过程及故障发展的原因,并从设备运维及调度处理方面提出建议。Taking a single-circuit line ground fault of a 10 kV double-circuit lines on the same tower developing into a double-circuit lines interphase ground fault and leading to line break as an example,the electrical characteristics of ground fault are analyzed theoretically.Combined with the analysis of wave recording data and on-site investigation data,the fault evolution process and causes of fault development are deduced,and suggestions are put forward from the aspects of developmental ground fault.
