高压架空输电线自动防冻方案

zhaogy2006

摘要: 介绍一种高压架空输电线自动防冻的方案，即在架空输电线上附着防冻自动控制器及其相连的发热电
& z$ E5 o" z9 g) j: Z线。当架空输电线温度低于3°C 时，防冻自动控制器将开启通电，使发热电线升温，提高架空输电线的温度，
所以不产生冰冻; 当升温到12°C 时，防冻自动控制器将关闭，停止通电。这样就可避免架空输电线冰冻的
危害。

Abstract: Introduce a plan of preventing the high voltage overhead transmission line from being frozen． In other
words，A antifreeze automatic controller and the heating line are attached with the high voltage overhead transmission
line． When the temperature is below 3 degree，the antifreeze automatic controller will be opened，the heating-line’s
temperature is begin to rise，the high voltage overhead transmission’s temperature is begin to rise． When the temperature
is higher than 12 degree，the antifreeze automatic controller is closed． Consequently，the high voltage overhead
transmission line will not be frozen any longer． So according the plan，the disaster which is caused by the frozen high
% U4 g" u, _  N: j1 Kvoltage overhead transmission line can be avoid．
Key words: the high voltage overhead transmission line; an antifreeze plan; an automatic antifreeze controller; the
heating line
