500kV永兴线松花江大跨越微风振动在线监测系统应用与研究

On-line monitoring analysis of Aeolian vibration of Songhua River longspan of Yongyuan-Xingfu 550 kV transmission line

针对远距离输电线路因微风振动造成线路疲劳断股的问题,阐述了导线、地线微风振动形成原理以及550 kV永兴线松花江大跨越微风振动在线监测系统设计方案,分析了微气象监测数据和微风振动监测数据,并开展大跨越导、地线微风振动的疲劳特性、振动特性及防振方案的研究,对保障线路安全运行具有重要的意义。

With the rapid development of electricity industry, the adoption of bundle conductor, long-distance transmission lines have become inevitable. Aeolian is a risky problem of overhead due to the conductor wire broken off sometimes for it. ment for Songhua River long span of Yongyuan-Xingfu This paper introduces the 550 kV transmission line. design of on-line high-capacity and transmission lines monitoring equip- Research on fatigue property, aeo- lian vibration performance, anti-vibration method, which will be significant to assure transmission lines safety.
