摘要
架空输电导线的覆冰舞动是一种低频、大振幅的自激振动,严重威胁着架空输电线路的安全。文章对导线舞动的模式、产生条件及防舞方法进行了概述,介绍了一种由具有刚性、耐腐蚀性和热塑性的非金属或金属材料预绞成型的架空输电导线覆冰防舞装置——扰流防舞器的组成及工作原因,并给出了其实际应用效果。
The overhed transmission line oscillation caused by ice coating is the self-excited vibration with low frequency and big amplitude, and it is serious to threaten the safety of transmission network.The paper described the patterns and producing condition of line oscillation,and anti-oscillation method.The composition and working principles of a device of anti - oscillation with disturbing flow were introduced,which has installation of anti - oscillation for ice coating of overhead transmission line with pre - twisted nonmetal or metal material of rigidity,corrosion resistance and thermoplastic.Its actual application effect was also given.
