Method for removing accumulated snow on high-altitude power transmission lines

Abstract

The invention provides a method for removing accumulated snow on high-altitude power transmission lines. The method includes measures of connecting various sections of power transmission lines with one another by load tap switches; enabling controllers of the load tap switches to control the load tap switches to act in a certain mode when ice and the snow cover the power transmission lines, to be more specific, sorting a plurality of groups of power lines in the ice and snow covered sections of power transmission lines, and sequentially and alternately concentrating total currents in the sections of power transmission lines into one of the groups of power lines until the ice and the snow which cover the various groups of power lines are melted. The method has the advantage that normal power supply of the power transmission lines to users can be unaffected in snow melting procedures.

Description

[0001] technical field

[0002] The invention relates to the field of power facility construction, in particular to a method for eliminating snow on high-altitude transmission lines.

[0003] Background technique

[0004] The high-altitude power line is the basic power facility for remote power transmission; during the power transmission process, it needs to withstand the climate test of various regions, for example, in some cold mountainous areas, the high altitude where the transmission line is located has extremely cold temperatures and often encounters rain Weather, at this time, the surface of the transmission line is very easy to accumulate snow and ice, resulting in a sharp increase in the weight of the transmission line, and then the power line is likely to break and fall when the wind blows. The current high-altitude power lines are twisted by steel wires, and basically all face this problem, which causes great troubles for the electric power construction departmen...
