| 摘 要： | 采用ABAQUS软件建立500 kV超高压输电线路的有限元模型,计算分析具有不同结构参数的耐张线路段在各种脱冰工况下导线的动力响应,获得导线冰跳高度和张力随时间的变化,进一步得到脱冰率、覆冰厚度、耐张段档数、档距以及高差等对导线脱冰后最大冰跳高度的影响规律,为重冰区超高压输电线路电线的间隙设计以及杆塔设计提供依据.

| Abstract: | Numerical models of typical 500 kV ultra-high voltage(UHV) transmission lines are set up in ABAQUS/CAE software.The dynamic response of the transmission lines with different structure parameters under various ice-shedding load cases are analyzed,and the variations of jump height and conductor tension with time after ice-shedding are obtained.The effects of different parameters(such as the number of spans,span length,height differences,the ice shedding rate,and initial thickness of the ice covering the condu... |
