摘要
针对电力系统中低压微机线路保护出现的"异常自动重合"现象,介绍了现场出现的2种"异常自动重合"的情况,分析了微机线路保护装置重合闸的充电条件及发生"异常自动重合"的主要原因,并提出了相应的现场解决方案。
Focusing on the abnormal automatic reclosing of MV and LV microcomputer-based line protection in power system,two kinds of exceptional automatic reclosing instances on site are introduced in the paper.The charge condition of line computer protection device’s reclosing and the main reasons for abnormal automatic reclosing are analyzed.Solutions to the problem are proposed at last.
