摘要
馈线终端(简称FTU)是配电终端的一种,主要用于10 kV架空线路柱上开关的监测、控制与故障检测功能,是馈线自动化的关键智能设备和基础控制单元。本文针对馈线终端在工程现场出现的问题以及国网对配电设备一二次融合技术的新要求,提出相应的改进措施或新思路,包括运用双向可控硅实现双路交流220 V电源切换技术、基于IGBT模块的单稳态永磁机构驱动控制技术、装置级现场更换技术等。
Feeder terminal(FTU)is a kind of power distribution terminal.It is mainly used for monitoring,control and fault detection of 10 kV overhead line column switches.It is a key intelligent device and basic control unit for feeder automation.This paper proposes corresponding improvement measures or new ideas for the problems of feeder terminals at the engineering site and the new requirements of the State Grid for the first-time fusion technology of power distribution equipment,including the use of two-way thyristors to realize dual-channel AC 220 V power switching technology.Single-stable permanent magnet mechanism drive control technology based on IGBT module,device-level field replacement technology,etc.
