A core portion of the lead is a lead core rod of a high-temperature-resistant carbon fiber complex material; and conductors are arranged outside the core portion, and divided into an inner layer and an outer layer, wherein each layer of conductors is formed by stranding multiple single-strand conductors, the cross section of each single-strand conductor in the inner layer is trapezoid, and the cross section of each single-strand conductor in the outer layer is circular. The lead of the utility model can improve current-carrying capacity of power transmission lines, is characterized by scratch and wear resistance during construction, and can be used as super-high voltage and ultrahigh voltage power transmission leads.
Description
Technical field
The utility model belongs to production and the application of high voltage electricity transmission conductive wire, specially refers to the new structure carbon fiber composite core wire.
Background technology
Carbon fiber composite core wire is a kind of energy-saving capacity-improving conducting wires of brand new, with conventional wires, compare, have lightweight, intensity is large, heat resistance is good, thermal coefficient of expansion is little, the high temperature sag is little, conductance is high, line loss is low, ampacity is large, corrosion resistance and good, be difficult for the series of advantages such as icing, comprehensively solved every technical bottleneck that the overhead power transmission field exists, represented the technology trends of following aerial condutor, contribute to construct safety, environmental protection, the efficient economizing electric power transmission network, can be widely used in old circuit and the transformation of power station bus capacity-increasing, new line is built, and can be used for large leap, large drop, heavy icing area, the circuit of the special climates such as high pollution and geographical occasion.
Carbon fiber composite core wire is divided into trapezoidal soft aluminium carbon fiber composite conductor and circular aluminum conductor carbon fiber composite conductor two classes by the kind difference of aluminium stranded conductor.The structure of circular aluminum conductor carbon fiber composite conductor is to take carbon fibre composite as plug, and at the two-layer certain thickness aluminium conductor of the coated with uniform of plug, the aluminium conductor cross section is circular; Trapezoidal soft aluminium carbon fiber composite conductor is comprised of light-duty carbon fiber composite core rod and certain thickness two-layer trapezoidal soft aluminium.
Than circular aluminum conductor carbon fiber, the compound wire trapezoid cross section is compacter than circular structure, can make wire minimizing icing and wind carry, and less diameter and more level and smooth outer surface can reduce aerodynamic coefficient, the harm that reduces aeolian vibration and wave.Be conducive to improve the corona inception voltage of wire, can reduce corona loss, reduce corona noise and radio interference level.Under same outer diameter as, close Unit Weight condition, trapezoidal shape makes the aluminium sectional area of ACCC reach 1. 29 times of conventional ACSR closely.Therefore can improve ampacity 29% left and right.Under 180 ℃ of conditions, move, the ampacity of ACCC is the twice of conventional ACSR in theory.But also there are many weak points in the ladder type soft aluminum conductor, the rear easy generation that rubbed of soft aluminium damages, and makes impaired place resistance increase and easily cause local overheating, causes the aluminum steel strength decreased; Easily be out of shape in work progress and produce pine strand, there will be the ring phenomenon under the high temperature thermal cycle, this has just increased difficulty of construction and cost to a certain extent.
The utility model content
The purpose of this utility model is to address the above problem, and a kind of new structure carbon fiber composite core wire is provided, and has both met the cross section compactedness of carbon fiber composite core wire, improve ampacity, can strengthen the wire external layer resistance to wear again, reduce the difficulty of work progress, cost-saving.
For achieving the above object, the utility model adopts following technical scheme:
A kind of new structure carbon fiber composite core wire, its minute three-decker, its core is high-temperature resistance carbon fiber composite conductor core bar, outside is electric conductor, conductor construction divides inside and outside two-layer, every layer of electric conductor forms by a plurality of sub-thread electric conductor strand systems, and the cross section of internal layer sub-thread electric conductor adopts trapezoidal, and the cross section of outer sub-thread electric conductor adopts circular.
Described core bar adopts carbon fiber to strengthen the continuous pultrusion of fire resistant resin, and resin system is thermoplasticity or thermosetting, and heat resisting temperature is more than 200 ℃.
Described electric conductor material is fine aluminium or aluminium alloy or copper or copper alloy or silver or silver alloy; Twist sub-thread when processed and independently twist system, or multiply is first after preformed plying, then make by the strand of the strand after plying.
Core of the present utility model is the carbon fiber enhancement resin base composite material body of rod, and the outside strand of the body of rod is shaped with two-layer electric conductor strand.
The rear easy generation that rubbed of the soft aluminium of skin of the soft aluminum complex lead of trapezoidal soft aluminium carbon fiber damages, impaired place resistance is increased and easily cause local overheating, cause the aluminum steel strength decreased, just effectively avoided this situation after changing the circular section aluminium conductor into, internal layer adopts trapezoidal soft aluminium structure simultaneously, makes again overall structure more compact.The carbon fiber composite core wire set of this new structure the advantage of trapezoidal soft aluminium and circular aluminum conductor, avoided cleverly again both deficiencies simultaneously.
The beneficial effects of the utility model are: the common carbon fibers composite conductor is lightweight, coefficient of linear expansion is little except having for the new structure carbon fiber composite core wire of preparation, without the excellent properties such as magnetic loss and thermal effect, has also possessed the incomparable advantages of other wires such as internal layer high current-carrying capacity and outer high-wearing feature.
After outer contact adopts the circular section aluminium conductor to replace trapezoidal soft aluminium, can effectively prevent that trapezoidal soft aluminum conductor soft aluminium in work progress from producing pine strand because of distortion, the ring phenomenon occurred under the high temperature thermal cycle, this has just reduced difficulty of construction to a certain extent, reduce construction cost, improved efficiency of construction; Internal layer adopts trapezoidal soft aluminium structure simultaneously, avoided again the not compactedness of circular configuration, improved ampacity, the rising of operating temperature has simultaneously also improved the anti-ice-snow of wire, freezing ability greatly, contribute to construct safety, environmental protection, efficient economizing electric power transmission network, there is larger economic and social benefit, especially in country instantly, with all strength in the controlling the trend of Resources for construction economizing type and friendly environment society, more demonstrate powerful realistic meaning.Be especially suitable for use as the electric power delivery guidewire under superhigh pressure, ultra high voltage and extreme weather conditions.
