摘要
输电线路接点是线路中的薄弱环节,在运行中经常出现发热烧坏,造成大量的停电事故。本文从高压输电线路接点温升在线监测的需求入手,分析了导线接点发热和断线的原因,对高压线路测温的理论依据、方案选择进行了分析探讨。重点介绍了高压输电线路接点温升在线监测系统的结构组成、工作原理、运行方式以及难点分析。
The paper begin with the re quirement of real time monitoring for high voltage transmission line＇s node temperature rise, discuss the theory bases and project choice of measure temperature at high voltage line, then emphasize introduce the design of system＇s configuration ,principle ,running mode and analysis of emphases, difficulty.
