摘要
近年来,我国输电线路舞动事故频繁发生,舞动影响的区域呈逐年扩大的趋势,因此绘制舞动分布图对于从技术性和经济性方面实现差异化的防舞设计具有重要的指导作用。本文通过对舞动频次法和气象法绘制舞动图的不同进行分析,得出了舞动图绘制的方法,并结合河南历史舞动情况的统计,对河南近10年舞动的气象要素分析,提出参考舞动气象特征绘制舞动图的方法。
In recent years, the accidents caused by gallop- ing of power transmission lines frequently occurt, and the area affected by galloping is increasing. Thus it is important to make a galloping distribution map for differential anti-galloping design both in technical and economic aspects. This paper in- troduces the galloping frequency method and galloping ; meteo- rological method and compares their application ranges and their merits and disadvantages. Based upon the statistics for the last ten years of provincial power grid transmission line gsllop- ing data the paper gave the dividing principle of power line gal- loping region on the basis of galloping occurrence rates. The provincial power grid galloping distribution map has been formed according the principle.
