摘要:
紧凑型输电线路由于相间距离小,导线覆冰舞动造成的相间闪络等危害已经成为紧凑型线路最主要的一种灾害形式.用有限元方法建立了特高压紧凑型连续三档线路相间间隔棒防舞计算模型,给出了4种档距情况下紧凑型线路相间间隔棒一般布置方案及加密布置方案.在4种不同档距及不同风速条件下,通过数值分析得到了相间间隔棒布置方法对舞动幅值及相间距的影响.根据数值计算得到的结果对紧凑型线路的防舞设计具有重要的指导意义.
Abstract:
Inter-phase flashover caused by galloping of transmission lines has become one of the most main disasters of compact type lines, due to the small phase distance of compact type transmission lines. In this paper, a continuous three-span analysis model of galloping was established by using the finite element method for compact type transmission lines. Two types of arrangement schemes of both general scheme and in thick scheme of interphase spacers have been provided four different spans. The effects on amplitude and the phase distance were acquired, which are caused by different arrangement scheme of interphase spacers, by numerical analysis for the ultra-high voltage compact type power transmission line under different spans and wind speeds. The numerical analysis results has certain instructive meaning on anti-galloping of the ultra-high voltage compact type power transmission line.
