一起线路故障引发的重合闸反复动作分析

Analysis of the Repeated Actions of Reclosing Triggered by a Line Fault

电力系统中重合闸是一项重要的继电保护技术,一般只允许动作一次,误动或者反复动作应视为一种不正常现象。介绍了由于某110kV线路故障引起重合闸反复动作(此时线路开关机构存在故障),造成开关不停的分合,对此给出了原因分析,并提出相应的整改措施。有力更好的开展继电保护工作、保证设备安全运行提供借鉴。

In electric power system,the reclosing is an important relay protection technology,which can only be allowed once,and the malfunction of the relay and the repeated actions should be regarded as a kind of abnormal phenomenon.The paper introduced due to a 110 kV line fault,causing reclosing repeated action（at the same time,the circuit breaker mechanism fault）,caused the switch on and off,The reasons for this are given,and put forward the corresponding improvement measures.It is conducive to better carry out the work of relay protection,to ensure the safe operation of the equipment to provide reference.
