摘要: 覆冰舞动灾害是严重威胁输电线路安全稳定运行的自然灾害之一。为了评估不同方案下防舞器的防舞效果,在线路现场观测以及基于曲梁建模并考虑防舞器分布的导线覆冰舞动方程基础上,利用平均法对2010年事故中双信5465线和安龙5466线出现的非线性振动现象进行了理论分析。对单独使用阻尼间隔棒和阻尼间隔棒-双摆防舞器配合使用的2类方案进行了效果评估。结果表明,2种方案的线路均体现出一定的抑制舞动效果,但总体来说,二者配合使用的效果更为明显。

Abstract: In order to better understand effects of different anti-galloping fittings arrangements, the nonlinear vibration properties of Shuangxin 5465 line and anlong 5466 line are analyzed theoretically through galloping equations with curved beams and anti-galloping fittings arrangements. Performances of two fitting scheme, namely spacers only and double-spacer pendulum damper combination, are evaluated. Results show that both arrangements have ability to suppress line galloping. However, combination of two schemes are more effective.

Key words: damp spacer, double pendulum damper, galloping of iced overhead transmission line, overhead transmission line, nonlinear dynamics
