摘要:

架空输电线路导线覆冰可能导致电网系统发生机械或电气故障,因此,确定导线设计冰厚对电网的安全稳定运行具有十分重要的作用。确定架空输电线路导线设计冰厚时,需要通过线径订正公式将不同导线直径上的标准冰厚折算至设计导线上。通过人工气候室内覆冰试验获取相关覆冰数据,针对不同覆冰类型分别拟合了导线的直径订正系数。结果显示:雾凇和混合凇的导线直径订正系数随着线径的增加而减小,且雾凇减小的趋势较混合凇明显;雨凇的导线直径订正系数随着线径的增加而增加。

Abstract:

Accreted ice on conductors in transmission lines may cause mechanical and electrical faults to power grid system, leading to the fact that the determination of designed ice thickness on conductors plays an important role for the safe operation of power grid. When determining the designed ice thickness of conductors in transmission lines, the standard ice thickness on different diameters should be computed to the specific diameter with using diameter correction formula. Related ice data was acquired through experiments in artificial climate chamber, and the diameter correction coefficients of conductors were fitted respectively according to different types of accreted ice. The results show that the conductor diameter correction coefficients of rime and mixed-phase icing decrease with the increase of conductor diameter, and the decreasing trend of the correction coefficient of rime is larger than that of mixed-phase icing; the conductor diameter correction coefficients of glaze icing increases with the increase of conductor diameter.
