Abstract
The invention relates to a triangular carbon fiber photoelectricity composite overhead conductor which comprises a photoelectricity composite structure and a high temperature resistant insulation material layer, wherein the photoelectricity composite structure is composed of a carbon fiber strength bearing part, a stainless steel optical unit and duralumin round lines. The cross section of the high temperature resistant insulation material layer is triangular, each corner of the triangular cross section contains one duralumin round line, the center of the cross section of the high temperature resistant insulation material layer contains the carbon fiber strength bearing part, and the stainless steel optical unit is contained in the gap among the duralumin round lines and the carbon fiber strength bearing part in the high temperature resistant insulation material layer. Compared with the prior art, the triangular carbon fiber photoelectricity composite overhead conductor has the advantages of being good in soft property and improved in strength of extension, meanwhile, the windage resistance of the triangular cross section is smaller than that of a round section, and therefore the reduction of waving of the overhead conductor is facilitated.
Description
Technical field
The present invention relates to the electric wire field, relate in particular to a kind of a kind of carbon fiber complex core times capacity electric power optical cable with electric power transfer and optical communication dual-use function of electric power transfer and power communication system, particularly city, rural area distribution network systems.
Background technology
Along with developing rapidly of China's economy, the obvious quickening of process of modernization, the continuous expansion of city size and the fast development of new countryside construction, electricity needs rapid growth.And, due to can source distribution and the imbalance of the western and eastern's development, be badly in need of solving the bottleneck problem that high-power, the long distance of the energy is carried.Although the construction parts of superhigh pressure has been alleviated this contradiction, be limited by the restriction of conventional steel core aluminum stranded wire bearing capacity, transmission line can't bear to bear the demand of the quick dilatation of transmission capacity, and electric power transfer becomes " bottleneck " of electric power industry development.At present, countries in the world are all at the novel built on stilts used for transmission line carrier of research, to replace traditional conventional steel reinforced aluminium conductor.The development of aluminium twisted wire with carbon fiber composite core, exploitation will greatly improve the conveying capacity of transmission line, and aluminium twisted wire with carbon fiber composite core is compared with conventional steel reinforced aluminium conductor, has the following advantages:
1. intensity is large, and aluminium twisted wire with carbon fiber composite core intensity is 2 times of conventional steel reinforced aluminium conductor.
2. conductance is high, and the conductivity of aluminium twisted wire with carbon fiber composite core is 63.2%, than conventional steel-core-aluminium hinge line conductivity, improves 3-4%.
3. low arc drop, aluminium twisted wire with carbon fiber composite core are compared with conventional steel reinforced aluminium conductor has significant low sag characteristic, and sag, less than 1/10 of conventional steel reinforced aluminium conductor, has improved the safety and reliability of wire operation at normal temperatures.
4. high temperature resistant, the serviceability temperature of conventional steel reinforced aluminium conductor is below 100 ℃, and aluminium twisted wire with carbon fiber composite core can effectively move under 180 ℃ of high temperature, and the short time can arrive 200 ℃.
5. lightweight, the proportion of carbon fiber plug is about 1/4 of steel, and the aluminium twisted wire with carbon fiber composite core unit weight is about the 60%-80% of conventional steel reinforced aluminium conductor.
6. corrosion-resistant, aluminium twisted wire with carbon fiber composite core is 2 times of conventional steel reinforced aluminium conductor useful life.
7. integrated cost is low.Because the aluminium twisted wire with carbon fiber composite core capacity can strengthen operation, and tensile strength is high, sag is little, the characteristics such as lightweight, and the span between bar, tower is increased, highly reduce, because intensity is high, can strengthen the span between bar, tower, reduce bar, tower more than 20%.Same capacity line cost is lower than plain conductor integrated cost.
8. save the consumption of half aluminium.From protection of the environment, energy savings, improve the human ecological environment aspect, have epoch-making meaning.
Although carbon-fibre wire has above plurality of advantages, can not realize communication function, also need separately to establish a communication line and could meet communication function, cause and repeat wiring.The wire wind resistance weak effect of existing circular cross-section in addition, the amplitude of waving is large.

Summary of the invention
Technical problem to be solved by this invention is to provide a kind of relative cost lower for the deficiencies in the prior art part, and the triangle carbon fiber photoelectric composite overhead wire of electric power transfer and communications dual-use function can be provided, and have good Anti-galloping effect.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of triangle carbon fiber photoelectric composite overhead wire, is characterized in that, comprises photoelectric composite structured, high-temperature insulation material layer that carbon fiber bearing member, stainless steel light unit and hard aluminium round wire form; The cross section of described high-temperature insulation material layer is triangle, each place, angle of its triangular-section respectively holds a hard aluminium round wire, cross-section center place at described high-temperature insulation material layer holds the carbon fiber bearing member, and the gap in described high-temperature insulation material layer between hard aluminium round wire and carbon fiber bearing member holds described stainless steel light unit; Described carbon fiber bearing member is the compound ultra-high strong heart yearn, the high-performance carbon fibre bundle, the high-strength basalt fibre bundle master core that comprise longitudinal extension, the high-strength S glass fiber bundle of continuous winding master core in the shape of a spiral, and with high-performance carbon fibre bundle, high-strength basalt fibre bundle, the fixed modified thermoplastic resin that is integrated of high-strength S glass fiber bundle; Described stainless steel light unit forms for by some optical fiber, being placed in a stainless steel protection pipe, and the stainless steel protection pipe adopts loose tube structure, the water-blocking material of filling continuously in stainless steel protection pipe space, and the stainless steel protection pipe extrudes one deck aluminium lamination outward.
Described carbon fiber bearing member is 7 bursts of stranded forming of carbon fiber.
The carbon fiber bearing member that the present invention adopts is by 7 bursts of stranded forming of carbon fiber, has compared to existing technology the characteristics that softness is good, tensile strength improves.The stainless steel tube that adopts extrudes one deck aluminium outward, can prevent the potential corrosion that different materials forms.Simultaneously, the windage of leg-of-mutton cross section is less than the windage of circular cross-section, is conducive to reduce waving of aerial condutor.
