输电线路导线覆冰舞动机理的讨论与研究

Discussion and research on mechanism of transmission line conductor icing

输电导线用来输送电力,一般由钢芯铝绞线制成,输电导线的结构与空气中的对流形成了振动。对物体振动的三种不同类型进行了介绍,从输电导线覆冰、风给予的激励、导电线路的参数和结构三方面入手,对覆冰导线产生舞动的原因进行了分析,对覆冰导线产生舞动的机理进行了分析。

The transmission wire is used to transmit power and is generally made of ACSR.The structure of the transmission wire and the convection in the air form a vibration.Three kinds of vibration of the object are introduced.The reasons of the galloping of the icing conductor are analyzed from the aspects of the icing of the transmission line,the excitation of the wind,the parameters and the structure of the conducting line.The mechanism of galloping was analyzed.
