摘要

采用数值模拟方法研究三相双分裂导线三角形排布线路相间间隔棒防舞方案设计。针对300m档距双分裂线路,数值模拟分析在风荷载作用下导线的舞动特征,设计4种相间间隔棒安装方案,并对各种方案的防舞效果进行模拟研究,得到设计三相导线三角形排布线路相间间隔棒防舞方案时需同时考虑导线垂直和水平振动模式的原则。基于此原则,设计400m和500m档距线路相间间隔棒布置方案,数值模拟进一步验证了其防舞效果。

Abstract

Anti-galloping design of interphase spacers in three-phase conductor lines with triangle arrangement is numerically studied. Based on the galloping characteristics of transmission line with 300m-span under wind load, four installation schemes of interphase spacers are presented and their anti-galloping efficiencies are numerically investigated. It is suggested that both vertical and horizontal vibration modes during galloping have to be taken into account in the installation design of interphase spacers, based on which anti-galloping schemes of interphase spacers for the transmission lines with 400m-span and 500m-span are designed and their anti-galloping efficiencies are further numerically proved.
