摘要
结合智能变电站验收中220 kV线路保护的压力低闭锁重合闸回路的问题,分析了智能变电站220 kV线路保护压力低闭锁重合闸开入构成的原理以及压力低闭锁重合闸开入异常的原因,为以后智能变电站验收220 kV线路保护的压力低闭锁重合闸回路提供借鉴.
Abstract
Based on the problem discovered in the pre-acceptance check of the reclosing loop of a low pressure latching for the 220 kV line protection in a smart substation,this paper discusses and analyzes the principle of the composition of the low pressure latching reclosing loop in the protection of 220 kV line in intelligent substations,as well as the reasons for the reclosing abnormality.This provides a reference for the future pre-acceptance check of the low pressure latching reclosing loop of 220 kV line protection in smart substations.
