Abstract
The invention discloses an ice-melting type overhead earth wire comprising a galvanized steel wire, a conducting element concentrically stranded on the galvanized steel wire, a galvanized steel strip concentrically lapped with a butt gap on the conducting element, and a reinforcing element concentrically stranded on the galvanized steel strip, wherein the conducting element is a copper core insulated wire, insulation of the copper core insulated wire adopts weather resistant cross-linked polyethylene, and the reinforcing element is a plurality of galvanized steel wires. The invention has the advantage that when a sheet of ice and snow is frozen on the ice-melting type earth wire, the insulated copper core is charged, and the outer layer galvanized steel wires generate eddy heat to melt the covered ice and snow, thereby protecting the overhead earth wire to be in safe operation.
Description
Technical field:
The present invention relates to a kind of cable technology field, particularly a kind of aerial condutor relates in particular to the ice-melt type overhead ground wire with ice-melt function.
Background technology:
Overhead ground wire does not nearly all possess from the ice-melt function at present, very easily causes accidents such as overhead transmission line collapses, broken string in case extreme ice and snow weather takes place, and causes large-area power-cuts.
Summary of the invention:
Technical problem to be solved by this invention is do not have the ice-melt function and a kind of ice-melt type overhead ground wire is provided to existing overhead ground wire.When the extreme low temperature bad weather occurring; The phenomenon of freezing appears in the overhead ground wire surface; At this moment promptly in the copper conductor of this ice-melt type overhead ground wire, fill the electric current with certain load, so outer zinc-coated wire produces the eddy-current heating phenomenon, temperature reaches as high as 90 ℃; Thereby the melting point that is much higher than ice is realized the deicing of circuit.
Technical problem to be solved by this invention can realize through following technical scheme:
Ice-melt type overhead ground wire comprises that zinc-coated wire, a concentric type are stranded in the wrapped reinforcing element on galvanized steel strip on the said wire element and the stranded said galvanized steel strip of concentric type in conducting element, concentric type gap on the zinc-coated wire.
In a preferred embodiment of the invention, said conducting element is a copper core insulation line, and the weatherability crosslinked polyethylene is adopted in the insulation of said copper core insulation line.
Said reinforcing element is some zinc-coated wires.
Advantage of the present invention is when condensing one deck ice and snow on the ice-melt type ground wire, in the insulated copper heart yearn, charges, and utilizes outer zinc-coated wire eddy-current heating with the ice dissolution that covers, thus protection overhead ground wire security of operation.
Description of drawings
Fig. 1 is an ice-melt type overhead ground wire radial cross-section of the present invention;
Embodiment:
The present invention combines specific embodiment to further specify as follows referring to accompanying drawing:
Referring to Fig. 1, the ice-melt type overhead ground wire shown in the figure comprises a zinc-coated wire 1, and this zinc-coated wire 1 adopts the mode of keeping flat to arrange, zinc-coated wire 1 adopts φ 2.5mm regular tenacity zinc-coated wire.
Concentric type is stranded on zinc-coated wire 1 has 6 conducting elements, and every conducting element is a copper core insulation line, and the conductor 2 of this copper core insulation line adopts φ 1.65mm, and purity is not less than 99.95%, resistivity is not more than 0.017241 Ω .mm
2/ m, elongation at break are not less than 25% stranded the forming of anaerobic annealed copper wire.The insulating barrier 3 of this copper core insulation line adopts black weather resistant crosslinked polyethylene insulation material, and insulating barrier 3 nominal thickness are: 0.4mm.The external diameter of copper core insulation line is between φ 2.3～φ 2.4mm.The differentiation of copper core insulation line adopts the black insulating surface to print different white numerals, as: 1,2,3,4,5,6.6 copper core insulation lines are to be not more than 14 times of pitch strandings of the stranded external diameter of copper core insulation line, and direction is a left-hand.
The concentric type gap is surrounded with galvanized steel strip 4 on 6 conducting elements, and galvanized steel strip 4 adopts cable armouring to use the low-carbon (LC) galvanized steel strip, and thickness is 0.2mm.
Concentric type is stranded in the outside of galvanized steel strip 4 has 12 zinc-coated wires to adopt φ 2.5mm regular tenacity zinc-coated wire as 5,12 zinc-coated wires of reinforcing element, adopts dextrad stranded, and twisting pitch is 10～14 times of stranded external diameters of this layer.
In sum; Ice-melt type overhead ground wire of the present invention has solved overhead transmission line under exceedingly odious meteorological condition; When the icing phenomenon appears in overhead ground wire; Adopt ice-melt type overhead ground wire of the present invention can effectively solve the icing phenomenon of overhead ground wire, thereby guarantee that overhead transmission line is effective, reliable, safe operation.It is a kind of desirable kind that is widely used in the overhead ground wire circuit.
