摘    要:基于大量文献分析总结了输电导线舞动的形成因素、舞动机理、防舞措施及舞动试验研究方法。结果表明:导线的舞动主要取决于覆冰、风激励、线路结构和参数;Hartog垂直及Nigol扭转舞动机理目前应用较广泛但不能解释各种类型的舞动现象;采取避舞、抗舞和抑舞措施可有效防止舞动危害;风洞和试验线路的试验是舞动研究的2种重要方法。最后提出了导线舞动研究中尚待解决的问题和进一步研究方向。

关 键 词:输电线路  舞动  防舞  机理  试验研究

Abstract:Based on analysis of a mass of references, this paper summarizes and analyzes the formative factors and mechanisms of conductor galloping, anti galloping measures, and methods for experimental investigation into conductor galloping. The results show that the formation of conductor galloping mostly depends on icing, wind as well as configuration and parameters of transmission lines. Den. Hartog mechanism and O. Nigol mechanism are two galloping mechanism which are relatively widely used at present, hut neither of them can interpret all different types of galloping phenomena. The harm resulting from conductor galloping can he effectively avoided, resisted or restrained if some measures are taken. Testing in wind methods for experimental investigation into conductor the research of conductor galloping and points out the tunnels and testing on transmission lines are two important galloping. Besides, this paper puts forwards the problems in orientation for further investigation.
Keywords:transmission line  galloping  anti-galloping  mechanism  experimental investigation
