摘要
采用ABAQUS有限元软件建立覆冰双分裂导线特征段线路模型,针对三角形、垂直和水平三种导线排布方式,数值模拟特征段线路的舞动过程,以及在安装相间间隔棒后的动力响应过程。基于线路在安装相间间隔棒前后的动力响应结果,对三种导线排布方式下相间间隔棒的防舞效果进行对比分析,得到相间间隔棒对垂直和三角形排布线路有较明显的防舞效果,而对水平排布线路几乎无效果的结论。
The numerical models of typical transmission line sections of iced double split conductors are set up by means of the finite element software ABAQUS.The galloping process of the line sections with different conductor arrangement,i.e,the triangle,vertical and horizontal arrangement,and the dynamic responses of the lines installed interphase spacers are numerically simulated.Base on the dynamic responses of the transmission lines without and with interphase spacers,the anti-galloping efficiency of the interphase spacers for the transmission lines with different conductor arrangement is assessed.It is shown that the anti-galloping efficiency of the interphase spacers for the lines with triangle and the vertical conductor arrangement is obvious and nearly nought for the line with horizontal arrangement.
