摘　　要：依据架空输电线路导线舞动产生的原因及形成机理,对西北某110 kV输电线路舞动故障原因和特点进行了分析,提出了采用失谐摆进行防舞的措施,并应用Den Hartog垂直舞动机理和O Nigol扭转舞动理论进行了相关设计,确定了失谐摆的参数(摆长和重量)和安装位置,并通过计算从理论上验证了其有效性.According to the cause and principle of overhead transmission line galloping,the reason and features of galloping of certain 110kV transmission lines in Northwest China are analyzed.Then an anti-galloping device by using detuning pendulums is designed.Furthermore,Den Hartog vertical galloping principle and O Nigol torsion galloping theory are used to identify the parameters（pendulum length and weight） of detuning pendulums and to locate installation position of the detuning pendulums.The result of the calculation shows that the approach is theoretically effective.
