Background
With the continuous development of economy in China, the coverage area of a power grid is increasingly wide, the load of the power grid is increasingly heavy along with the continuous increase of the transmission voltage level, and the difficulty in managing the transmission line is increased continuously. Because the electric power and the electric energy adopt a long-distance and large-capacity transmission mode, the transmission line is usually completed by supporting exposed wires by a high-voltage frame. Because the exposed wires are exposed for a long time, ice coating can be formed on the surfaces of the wires in the cold environment in winter, and the mechanical load of the power transmission line is increased. When the ice coating is serious, once the load of the power transmission line exceeds the self strain strength, the power transmission line can cause power grid disasters such as conductor galloping, line breakage, tower falling, ice coating and the like. This causes great harm to the safe operation of the power grid, and causes huge economic loss to the nation and people.
