摘要
基于110 kV连南线同塔双回垂直排列线段现状和舞动模型调查,分析了导线的舞动原因,研究了导线发生舞动机理,提出了无覆冰的邓哈托舞动模式。并比较分析了集中安装重锤和相间间隔棒两种方案。结果表明,选择相间间隔棒方案可治理导线舞动,提高了输电线路的供电可靠性和健康运行水平,为输电线路因特殊风向诱发的邓哈托舞动模式治理提供了参考依据。
Based on investigation of the status of 110 kV Liannan transmission line double circuit section where the line is vertically arranged on the same tower,and the swaying pattern,the main cause of the wire swaying is analyzed.Then,the swaying mechanism of the wire is studied,and the Den Hartog swaying pattern without ice coating is put forward.Specifically,two schemes,centralized heavy-punch installation and inter-phase spacers,are compared.The results show that the scheme of inter-phase spacers can bring the wire swaying under control and enhances the reliability and safety of the power supply transmission lines,which provides basis for regulation of the Den Hartog pattern swaying induced by particular wind directions in transmission lines.
