摘要
针对系统保护、发变组保护电气二次回路接口部分存在的问题,以某电厂2号机组发电机变压器线路组接线为例,从插件内部永跳回路原理等方面进行分析,认为两永跳继电器因发热致使接点粘连始终接通是导致GE和南瑞发变组保护"系统保护"开入信号一直存在,手动不能复归的原因,提出了进行组态逻辑设计的解决方案。
For system protection,a variable set electrical secondary loop of protection problems existing in the interface section,to a certain power plant no.2 machine generator transformer connection line group,for example,never jump from inside the plug-in circuit principle diagram for root cause analysis,think two wing hop relay contact adhesion due to any fever is always connected to GE and south red hair group protection"system to protect"analog signal,The reason of manual can not return,and put forward the solution of configuration logic design.
