Abstract
A kind of composite construction automatic defrosting overload conductor, the internal layer stranded core quick sensing layer of outer cladding power, power quick sensing layer outer cladding temperature-sensitive heating layer, the temperature-sensitive heating layer stranded core of outer cladding outer layer.This wire is mainly used in snow disaster or the more serious area of sleet disaster, has stronger ice and snow defensive ability/resistance ability, and integrated cost is low, and line loss is little, and without later maintenance.
Description
Technical field
The present invention relates to a kind of wire, be specifically related to a kind of composite construction automatic defrosting overload conductor.
Background technology
Existing aerial condutor mainly based on steel-cored aluminium strand, this wire outer surface curl, without snow disaster, freeze
In the case of the natural disasters such as rain, the requirement of safety power transmission can be met, but in the case of meeting with heavy snowfall, sleet weather, lead
Line surface is susceptible to accumulated snow, hangs ice even icing phenomenon, and wire weight is significantly increased and causes conductor cord disconnection or shaft tower to collapse,
Heavy damage supply network.2008, there is lasting heavy snowfall and sleet weather in south, and a large amount of transmission towers are the thickest because of icing snow,
Can't bear the heavy load and collapse, cause 17 provinces and regions circut breaking occur, some areas electric power system is paralysed, and government department can only light
Wax candle meeting commander combat a natural disaster, and the common people and country have all thus suffered from huge loss.Therefore, it is necessary to existing aerial condutor is entered
Row improves, and strengthens its anti-ice-snow ability.
For above-mentioned background, in industry, propose a lot of scheme tackling aerial condutor icing, but due to ice disaster
Uncertainty, input cost and the equilibrium problem of risk, these schemes have the defect that comparison is great, mainly have following several side
Case: (1) wire uses special-shaped single line stranded, such as Z-type single line, reduces the gap between core and core, reduces ice and snow attachment
Probability, the reliability of this scheme is low, and the anti-icing ability of anti-sleet is more weak.(2) one layer of hydrophobic material of conductive line surfaces coating, as
The macromolecular materials relatively low to ice sheet adhesive force such as organosilicon, fluorine Si acrylate copolymer, this scheme later maintenance workload
Greatly.(3) high-thermal conductive metal material or nonmetallic materials are importing directly in circuit, by applying reactive power, increase office
The modes such as portion's electric current, high temperature eliminates ice and snow, and this scheme line loss is big, and increases wire deadweight, does not have practicality.(4)
Introducing the PTC exothermic material of lighter in weight in wire outermost layer, when temperature is less than certain value, ptc material resistance value is relatively low,
Material is in "on" position and starts heating, and during persistent fever to its Curie temperature, resistance value drastically raises, and material becomes insulation shape
State, after failure of current, exothermic material is gradually cooling to below Curie temperature, and the Curie temperature slightly above zero that only need to control material is taken the photograph
Family name's degree can ensure that cable surface temperature will not be constantly in below zero degrees celsius, thus prevents its surface accumulated snow or icing.This
As long as the defect of kind of scheme is ambient temperature is less than temperature in the office of ptc material, even if not having snow disaster or sleet, ptc material
Still can Automatic Cycle generate heat, a large amount of electric energy are converted into heat energy, and line loss is bigger.
Summary of the invention
It is an object of the invention to provide a kind of composite construction automatic defrosting overload conductor that can effectively solve the problems referred to above.
For reaching above-mentioned purpose, the solution that the present invention takes is: a kind of composite construction automatic defrosting overload conductor,
The internal layer stranded core quick sensing layer of outer cladding power, power quick sensing layer outer cladding temperature-sensitive heating layer, temperature-sensitive heating layer outer cladding outer layer twists
Zygonema core.
This wire is mainly used in snow disaster or the more serious area of sleet disaster, has stronger ice and snow defensive ability/resistance ability, comprehensively
Low cost, line loss is little, and without later maintenance.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of the present embodiment.
In figure: 1, the stranded core of internal layer, 2, the quick sensing layer of power, 3, temperature-sensitive heating layer, 4, the stranded core of outer layer.
Detailed description of the invention
Below in conjunction with illustrative embodiments and accompanying drawing thereof, further illustrate the present invention, but embodiment should not be construed as this
The concrete restriction of invention.
See Fig. 1, a kind of composite construction automatic defrosting overload conductor, the internal layer stranded core 1 quick sensing layer of outer cladding power 2,
Power quick sensing layer 2 outer cladding temperature-sensitive heating layer 3, the stranded core of temperature-sensitive heating layer 3 outer cladding outer layer 4.
See Fig. 1, if the stranded core of described internal layer 1 stranded is formed by carried interest round conductor is regular.
Seeing Fig. 1, described round conductor is copper, aluminum or aluminum alloy material.
Seeing Fig. 1, the quick sensing layer of described power 2 is made up of force-sensitive silicon rubber.
Seeing Fig. 1, described temperature-sensitive heating layer 3 is made up of polymer matrix PTC material.
Seeing Fig. 1, the stranded core of described outer layer 4 is formed by some Z-type single lines are stranded.
This wire compared with prior art has some advantage following: (1) only uses Z-type single line stranded at outermost layer, its
Remaining single line uses conventional circular configuration, can reduce the probability of ice and snow attachment to a certain extent, and the most beneficially control is manufactured into
This；(2) the quick sensing layer of power 2 and temperature-sensitive heating layer 3 bilayer combination ice-melt snow structure are used, only outside wire is by ice and snow etc.
When power effect exceedes certain value and temperature less than ptc material Curie temperature, temperature-sensitive heating layer 3 automatic heating that just can be energized melts ice
Snow, solves the problem that low temperature also can produce certain loss without heating layer during snow；(3) non-ice-melt snow state is descended, the quick sensing layer of power
2 and temperature-sensitive heating layer 3 Inside and Outside of Conductor layer is dielectrically separated from, increase the surface area of conductor, reduce the AC resistance of conductor,
Reduce transmission losses.
The above is only the preferred embodiment of the present invention, for those skilled in the art, not
On the premise of departing from the principle of the invention, it is also possible to making some improvement, these improvement also should be regarded as protection scope of the present invention.
