At present,we or foreign have not dine out the universal general deicing ice's method to possibly apply to transmission line under the kinds of climate and micro-relief, this article have used the regelation load analysis and computation about the transmission line, we thought that it is passable to prevent the regelation effectively, to reduces the line compound stress and the non-uniform regelation rate the different span, about the different elevation difference and the non-uniform regelation when the appropriate position of line have finded the installment of deicing-device, to create the disaster to the transmission lines and the iron towers, and can guarantee the electrical network safely and steadiely operation.

目前，国内外还没有可以普遍通用的除冰方法可以应用于各种气候和各种微地形的输电线路，本文通过对输电线路覆冰荷载的分析计算，认为在线路适当位置安装除冰装置能有效防止不同档距、不同高差和不均匀覆冰线路的覆冰，减少线路综合应力和不均匀覆冰率，对输电线路及其铁塔造成灾害，保证电网安全稳定运行。

In this paper, the method system of using Fuzzy-AHP to make up the input - output form and to establish input - output mathematical model is advanced, and it is used to study theoretical electric-price for a regin.
