| 摘 要： | 介绍了线路覆冰的形成及危害。根据对覆冰线路所取得的经验,提出对重冰线路防护对策采取"避、抗、融、改、防"5项措施。对新建线路,指出设计覆冰线路的要点是合理划分冰区,选取不同的设计冰厚进行线路设计;而对设计冰厚取值偏低,抗冰能力弱的已运行线路,提出了一些行之有效的抗冰措施,力求做到确保线路安全运行。

| Abstract: | The paper introduced the form and harm of icing on power transmission line.According to the experience of icing on line,the 5 measuresto avoid,fight,melt alter,guard against were put forward for preventing icing on power transmission line.It is pointed out that the key point for new built line to design icing line is reasonably to partition ice district and to select different ice thick to carry out line design;and the measures for effectively fighting icing are put forward to make great effort to ensure th... |
