摘要
以神木—忻州II、I回500kV输电线路为例,根据覆冰形成机理和统计特性,分析山区导线覆冰规律,由当地实测资料确定覆冰参数。联系沿线气候与地形地貌特点划分冰区,并论证分区的合理性和必要性。在此基础上对线路路径进行优化,为线路防冰设计的安全性和经济性提供保证。
Using the Ⅰ and Ⅱcircuits of Shenmu -Xinzhou 500 kV transmission line as an example, based on icing mechanism and statistic characteristics, this paper analyzes the rules of conductor icing in mountain areas, and determines icing parameters with local measurements. Icing zones are plotted based on the weather and topography characteristics along the line, and its rationalities and necessities are also explained. Based on these analysis, route optimization of transmission line is performed to ensure the safety and economy of icing prevention design.
