Description
Technical field
The utility model relates to the rare wire of a kind of graphite used for intelligent electric network.
Background technology
Along with the progress of science and technology, the electric pressure of circuit is more and more higher, and the fast development of the distribution of china natural resources and east economy, determine the transportation characteristics that China's transmission line presents ultra high voltage, long distance.Wire through different climatic provinces, all can should think better of the anti-disaster ability etc. of electrical grid in long distance delivery process from power transmission engineering design, conductor selection, construction and operation.And powerline ice-covering, snow are the main natural calamities of power transmission network in winter in spring, the accidents such as bar (tower), broken string and conductor galloping of falling caused are the major reasons causing transmission of electricity to interrupt.Along with the deterioration of global climate condition, there is larger fluctuation in China's most area weather in recent years.When often there is the terrible weather situations such as sleet, sleet, dense fog, very easily there is icing phenomenon in transmission line.After wire generation icing, when temperature is lower, sleet continues, icing cannot melt, and ice constantly condenses in around wire, increases continuously.Once the ice load of electrical lead is overweight, line-sag strengthens, and transmission pressure ground short circuit will occur, cause line tripping, serious icing will cause transmission tower distortion and collapse.People have thought that various way is to reduce ice damage, as applicant has successively applied for 20072036925.4 " ice-and-snow removing conductors " and 200820041021.8 " Anti-ice-and-snow wire ", these two kinds of wires can reduce ice damage to a certain extent, but the ice melting technology that these two kinds of wires adopt, the ice sheet of conductive line surfaces is needed to melt, its major defect existed is: one is need high-resistance material energising to heat up, and adds circuit operating cost; Two is them is carry out ice-melt again after conductor glaze formation, actual wire freeze after the weight of wire greatly increase, its fail safe reduces greatly.Therefore, need to develop a kind of non-icing wire at low ambient conditions and comprehensively solve the problem that wire applies in heavy icing area.
Utility model content
The purpose of this utility model comprehensively solves wire to apply the problem run in heavy icing area, provides a kind of not-easy-to-freeze, good corrosion resistance, Anti-galloping, withstands corona and radio interference, make the wire of transmission line Anti-ice-and-snow wire that is safer, more environmental protection.
The technical scheme realizing the utility model object is: the rare wire of a kind of graphite used for intelligent electric network, is characterized in that: be followed successively by strengthening core, inner conducting layer and outer conducting layer from the inside to the outside; Described outer conducting layer is stranded aluminum or aluminum alloy single line; At the outer surface of described outer conducting layer or have hydrophobicity Graphene coating at the outer surface of the every root single line of described outer conducting layer; The thickness of described hydrophobicity Graphene coating is 0.2 μm ~ 0.2mm.
The aluminium single line of described outer conducting layer is molded line.
Described outer conducting layer is by trapezoidal or S shape is Z-shaped or lambdoid molded line is stranded forms a ganoid cylinder.
Described inner conducting layer is one deck aluminum or aluminum alloy single line, or is the stranded aluminum or aluminum alloy single line of multilayer.
Have employed technique scheme, the utility model has following beneficial effect: (1) the utility model scribbles one deck grapheme material due to outer conducting layer surface, Graphene is the material with carbon element with two-dimensional nanostructure, there is ultra-high conductivity and good hydrophobicity, wire does not freeze, can well ice damage be reduced, improve the security reliability that transmission line runs.Therefore this wire not only has anti-freeze, corrosion resistance characteristic, reduces aeolian vibration and the harm of waving simultaneously, while also can reduce the level of corona and radio interference, make that the wire of transmission line is safer, more environmental protection.
(2) the utility model has widened all kinds of wire range of application, without the need to selecting the aerial condutor of Extra High Strength for heavy icing area, reduces transmission line construction cost.
(3) conductive line surfaces of the present utility model is very smooth, can well reduce the level of corona and radio interference, makes that the wire of transmission line is safer, more environmental protection.
(4) Graphene coating has good electric conductivity simultaneously, under same cross-sectional, can reduce conductor resistance, thus reduces line loss, realizes energy-conserving and environment-protective,
(5) wire of the present utility model has good weatherability, greatly can improve wire useful life.
