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
The present invention relates to power line deicing technical field, be specifically related to a kind of deicing carbon fiber high-low pressure aerial cable.
Background technology
Along with the develop rapidly of economy, overhead transmission line is widely adopted, it is economical that overhead transmission line has erection, on-load can high, maintenance easily a little, but the time in winter can work as wire cooling in 0 DEG C and following cloud or in mist water droplet and transmission line wire surface collision and freeze time wire icing phenomenon produce, the power circuit loss that such as China's large area sleet in 2008 causes, this is that in transmission line wire because water droplet surrounds and air-flow, supercooling water droplet collides, and is frozen in conductive line surfaces and forms icing.First wire icing grows on windward side, and as wind direction does not occur sharply to change, on windward side, ice covering thickness will continue to increase.When windward side, ice reaches certain thickness, and when its weight is enough to wire is reversed, wire twists phenomenon; Wire reverses again, and icing will continue to grow up and become large, finally on wire, forms circular or oval icing.
The mechanical load that wire icing increases exceed design permissible value to a certain extent time, cause broken string, the accident of falling shaft tower; Up and down or horizontal wire, there is asynchronous jump wave because wire icing come off, cause up and down or horizontal wire close to phase fault tripping operation occurs.
Summary of the invention
The invention provides a kind of deicing carbon fiber high-low pressure aerial cable, the cable existed to solve prior art freeze cause breaking, short circuit tripping operation and the problem of shaft tower of falling.
The present invention includes high-tension cable, high-tension cable is made up of the high-voltage cable of inside and the insulating barrier on surface, solving technical scheme that its technical problem adopts is that the surface of insulating layer of high-tension cable arranges carbon fiber heating line, and the insulating barrier inside of carbon fiber heating line arranges some carbon fibers.
Above-mentioned carbon fiber heating line parallel is placed on the surface of insulating layer of high-tension cable.
Operation principle of the present invention is: the carbon fiber in carbon fiber heating line is a kind of black matrix material, electric heating conversionization efficiency is than metal heating improve 30%, electrothermal efficiency about 100%, when there is icing phenomenon in high-tension cable surface, the carbon fiber heating line of the surface of insulating layer of high-tension cable can be switched on power, convert electrical energy into heat energy by carbon fiber, thus the ice on high-tension cable surface is melted rapidly, ensure the normal work of high-tension cable.
The present invention can the carbon fiber heating line of heating power by arranging on high-tension cable surface, carbon fiber is utilized to convert electrical energy into heat, thus effectively ensure that high-tension cable normally runs in severe cold area or in winter, there is the advantage that structure is simple, easy to use, cost is low and safe and reliable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is appearance schematic diagram of the present invention;
Fig. 2 is cross-sectional view of the present invention.
1 high-tension cable, 2 carbon fiber heating lines, 11 high-voltage cables, 12 insulating barriers, 21 insulating barriers, 22 carbon fibers in figure.
Embodiment
As depicted in figs. 1 and 2, a kind of deicing carbon fiber high-low pressure aerial cable, comprise high-tension cable 1, high-tension cable 1 is made up of the high-voltage cable 11 of inside and the insulating barrier 12 on surface, insulating barrier 12 surface of high-tension cable 1 arranges carbon fiber heating line 2, insulating barrier 21 inside of carbon fiber heating line 2 arranges some carbon fibers 22, and carbon fiber heating line 2 is parallel is placed in the insulating barrier 12 of high-tension cable 1 on the surface.
Operation principle of the present invention is: the carbon fiber in carbon fiber heating line is a kind of black matrix material, electric heating conversionization efficiency is than metal heating improve 30%, electrothermal efficiency about 100%, when there is icing phenomenon in high-tension cable surface, the carbon fiber heating line of the surface of insulating layer of high-tension cable can be switched on power, convert electrical energy into heat energy by carbon fiber, thus the ice-out on high-tension cable surface is fallen, ensure the normal work of high-tension cable.
