Embodiment Construction

[0013] like figure 1 and figure 2 As shown, a high-voltage and low-voltage overhead cable of deicing carbon fiber comprises a high-voltage cable 1. The high-voltage cable 1 is composed of an internal high-voltage cable 11 and an insulating layer 12 on the surface. The surface of the insulating layer 12 of the high-voltage cable 1 is provided with a carbon fiber heating wire 2. Several carbon fibers 22 are arranged inside the insulation layer 21 of the carbon fiber heating wire 2 , and the carbon fiber heating wire 2 is placed on the surface of the insulation layer 12 of the high voltage cable 1 in parallel.

[0014] The working principle of the present invention is: the carbon fiber in the carbon fiber heating wire is a black body material, the electrothermal conversion efficiency is 30% higher than that of metal heating, and the electrothermal efficiency is about 100%. When the surface of the high-voltage cable freezes, the high-voltage cable can be The carbon fiber heating...

Abstract

The invention relates to a deicing carbon-fiber-based high-low-voltage overhead cable comprising a high-voltage cable. The high-voltage cable is formed by an internal high-voltage cable wire and an insulating layer arranged on the surface; a carbon-fiber heating wire is arranged on the surface of the insulating layer of the high-voltage cable; and a plurality of carbon fibers are arranged inside the insulating layer of the carbon-fiber heating wire. According to the invention, because the carbon-fiber heating wire that can be electrified and carry out heating is arranged on the surface of the high-voltage cable and the electric energy can be converted into heat by the carbon fiber, the high-voltage cable can work normally and effectively at a severe cold area or in winter. The cable has advantages of simple structure, convenient usage, low cost, and high safety and reliability.

Description

technical field [0001] The invention relates to the technical field of power line deicing, in particular to a deicing carbon fiber high and low voltage aerial cable. Background technique [0002] With the rapid development of the economy, overhead lines are widely used. Overhead lines have the advantages of economical erection, high load capacity, and convenient maintenance. However, in winter, when the conductor is cooled at 0 ℃ or below, the clouds or water droplets in the fog When the wire surface of the transmission line collides with and freezes, the phenomenon of wire icing occurs, such as the loss of power lines caused by the large-scale freezing rain in my country in 2008. icing on the surface of the wire. The icing on the wire first grows on the windward side, and if the wind direction does not change sharply, the thickness of the ice on the windward side will continue to increase. When the ice on the windward side reaches a certain thickness and its weight is enoug...
