摘要:
在中重覆冰区的线路设计中,覆冰厚度的取值直接影响线路的安全性和经济性.以神农架某110 kV输电线路设计为例,分析附近已有线路的覆冰情况,探讨影响覆冰厚度的因素,主要包括气象条件的差异、海拔高程的影响、地形条件、导线悬挂高度、导线的截面和直径等.根据不同的海拔高度对设计线路进行冰区划分,并对覆冰过载能力进行计算,所得结果满足覆冰厚度要求.
Abstract:
The value of Ice thickness has a direct bearing on the safety and economy of transmission lines when it comes to designing transmission lines in medium and heavy ice areas. The design of 110 V transmission lines in Shennongjia region was taken as an example to study the operation and ice of the existing lines in the neighborhood during ice thickness partition. To be more exact, the factors contributing to ice thickness were researched, including differences in weather, influence of altitudes, terrain conditions, as well as height, cross-sections and diameter of conductors. Ice regions of transmission lines were divided according to altitudes, and the overload capacities of ice were also calculated. The results meet the demands of ice thickness.
