摘要
为实现高压系统控制与保护系统的双重化配置,电力系统在保护双重化的基础上,同步进行了断路器操作回路的双重化配置,在操作箱及断路器的更换过程中,遇到了诸如压力闭锁、防跳、非全相跳闸等相关回路的配置等问题,对实际工作值得分析以及进行相应的处理。
In order to realize double configuration of control and protection system of HV electric power system, based on the doubling of protection system,the double configuration of disconnector operating circuit is synchronistically made. When replacing operative boxes and disconnectors,the configuration problems of many relative circuits are discovered ,such as pressure blocking ,spring prevention ,open-phase trip and so on. In actual work these problems are worth to be analized and handled.
