Abstract
The invention relates to a low-swinging carbon fiber composite core photoelectric composite overhead conductor which sequentially comprises a stainless steel optical unit, a carbon fiber composite core and a duralumin molded line outer layer from inside to outside. The stainless steel optical unit is composed of a plurality of optical fibers which are arranged in a stainless steel protection pipe. The carbon fiber composite core is a high-strength conductive composite material composed of epoxy resin, nanometer expanded graphite with the expansion multiple more than 100 and reinforcing carbon fibers. Spiral surrounding stripes are arranged on the outer contour of the duralumin molded line outer layer. Compared with the prior art, the low-swinging carbon fiber composite core photoelectric composite overhead conductor has the advantages of being good in softening performance and improving tensile strength. Meanwhile, the spiral surrounding stripes are arranged on the outer contour of the duralumin molded line outer layer, and therefore reduction of swinging 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.Existing wire wind resistance weak effect 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 low overhead lead having carbon fiber complex core photoelectric composite structure of waving 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 hanging down waved overhead lead having carbon fiber complex core photoelectric composite structure, it is characterized in that, comprises successively from inside to outside stainless steel light unit, carbon fiber complex core, duralumin molded line skin; 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 complex core consists of at the high-strength conducting composite material that the nano expanded graphite more than 100 times and reinforcement carbon fiber form epoxy resin, expansion multiple, described reinforcement carbon fiber is that carbon fiber wire, ceramic fibre silk and glass mat are made by thermosetting resin cured typing, and described carbon fiber wire is the filament of being made by polyacrylonitrile-based carbon fibre cellulose mixture carbon fiber; On the outer field outline of described duralumin molded line, the spiral surrounding striped is set.
The carbon fiber complex core that the present invention adopts, have the characteristics that softness is good, tensile strength improves compared to existing technology.The stainless steel tube that adopts extrudes one deck aluminium outward, can prevent the potential corrosion that different materials forms.Simultaneously, arrange on the outer field outline of duralumin molded line around barber-pole stripes, the aerodynamic shape at this flow guiding casing tube position of spiral-shaped change, the wind-engaging cross section that duralumin molded line skin is gone up along its length constantly changes; It is irregularly shaped can also making icing profile outside duralumin molded line skin under clammy weather, cross section is changed along the hand of spiral, so that the mutual interference of aerodynamic effects phase and restriction that wind-force produces, thereby destroyed the condition of dancing: its lift coefficient is reduced, the lift coefficient curvilinear motion tends to be steady, the increase of its resistance coefficient can make wire consume more energy in motion process, is conducive to reduce the transmission line galloping probability and reduces the transmission line galloping amplitude.Owing to having adopted such scheme, make the present invention in use, can reduce windage, and reduce the transmission line galloping probability and reduce the transmission line galloping amplitude.
