摘　　要：在恶劣气象条件下,如强风、冰雹等,输电线路尤其是分裂导线容易发生舞动现象,这不仅严重威胁到电网的安全运行,还可能造成导线断股、金具磨损、铁塔损坏等严重后果。因此,探索有效的防舞措施成为当前电力领域研究的热点之一。带电加装双分裂相间间隔棒作为一种新型的防舞技术,具有显著的防舞效果、良好的经济性和适用性。文章从地形、气象条件及输电线路的特点方面,对一条220kV处于山区地段的线路多次舞动事故原因进行了分析,根据输电线路的特点和现行的防舞动经验提出了简单易行的防舞动措施,旨在为输电线路舞动治理提供新的思路和方法,保障电网的安全稳定运行。Under adverse weather conditions such as strong winds,hail,etc.,transmission lines,especially split conductors,are prone to dancing,which not only seriously threatens the safe operation of the power grid,but may also cause serious consequences such as wire breakage,hardware wear,and tower damage.Therefore,exploring effective anti dancing measures has become one of the hot topics in the current research of the power industry.As a new type of anti dancing technology,the installation of double split interphase spacers with electricity has significant anti dancing effects,good economy,and applicability.The article analyzes the causes of multiple dancing accidents on a 220kV transmission line located in mountainous areas from the perspectives of terrain,meteorological conditions,and the characteristics of transmission lines.Based on the characteristics of transmission lines and current anti dancing experience,simple and feasible anti dancing measures are proposed,aiming to provide new ideas and methods for the treatment of dancing on transmission lines and ensure the safe and stable operation of the power grid.
