摘要

针对 WBT-822A 型备自投保护与 RCS-941 型线路保护二次回路配合上存在的问题

根据《10 kV-110(66)kV线路保护及辅助装置标准化设计规范》进行深入分析

提出了有效的解决方案。结果表明:在进线保护操作箱回路增加一个重动继电器

可消除备自投误动或拒动的安全隐患

为电网的安全稳定运行提供了保障。

Abstract

Aiming at the problems of secondary loop coordination between the type of WBT-822Astandby power auto-switching in protecting device and the type of RCS-941 line protection device

ac?cording to ’Standardzation design criterion for 10 kV-110(66) kV transmiting lines protection and as?sistant equipment ’makes deep analysis

puts forward solving schemes. The result shows that addinga reset relay in incoming line protection operating box loop can eliminate safety hidden trouble such asmiss or refuse operation of standby power auto-switching in protecting device and guarantee powergrid operating safely and stably.
