500kV平洛送电线大跨越微风振动测试

Field measurement of aeolian vibration of Pingwei-Luohe 500 kV transmission line

微风振动是造成架空线疲劳断股的主要原因 ,随着大跨越架空输电线路的广泛应用 ,微风振动现象越来越引起广大专业技术人员和科学工作者的极大关注。文章根据 IEEE架空线测振标准 ,对 5 0 0 k V平洛送电线路工程淮河大跨越风振水平进行现场测试 ,根据分析测振结果 ,确认该大跨越工程的防振措施是稳妥的。

With the extensive application of overhead transmission lines,the phenomenon of aeolian vibration is drawing more and more attention of professionals in the field.This paper deals with the field measurement of aeolian vibrations on Huaihe River crossing of Pingwei Luohe 500kV transmission line.Based upon the field measurement analysis, it is concluded that the design of preventing the project from aeolian vibration is effective.
