摘要(Abstract)：
配电网线路故障处理过程中,由于强试送、拉路操作以及单相接地时的异常运行状态,导致衍化出新的故障。以具体实例分析故障衍化过程及产生原因,归纳出配电线路故障可能存在的典型故障衍化过程,探讨相应的配电网调度策略。
In handling line faults of distribution networks, abnormal operation conditions resulting from forced line energization, circuit braking and single-phase earthing lead to new faults. The paper, through specific cases, analyzes the fault evolution process and the causes; besides, it summarizes possible typical evolution process of distribution line faults and discusses corresponding distribution network dispatching strategy.
