摘要
在220 kV线路保护投入单相重合闸情况下,部分运行检修人员认为220 kV线路保护中"沟通三跳"压板一旦投入,作用就相当于闭锁重合闸,重合闸正常投入时,"沟通三跳"压板应退出。针对这一认识误区,简述了"沟通三跳"的由来及不同220 kV线路保护"沟通三跳"压板投退的不同点,对编制相关220 kV线路保护运行规程、典型操作票有一定的借鉴意义。
When single-phase reclosing occurs for 220 kV transmission line protection,part of operation and maintenance personnel mistakenly believe that lock reclosing will occur once the communication triple trip plate is enabled,and the communication triple trip plate will be out of service when reclosing normally.This paper introduces the origin of communication triple trip plate and the differences between the 220 kV transmission protection communication triple trip plate in service and out of service based on the misunderstanding above,and can serve as a reference for compilation of operation regulations and typical operation ticket of 220 kV line protection.
