Description
Technical field
The utility model relates to the electric power transportation art, relates in particular to a kind of carbon fiber photoelectricity composite cable with temp sensing function.
Background technology
Along with China's rapid economic development, the obvious quickening of process of modernization, the continuous expansion of city size and the fast development of new countryside construction, electricity needs increases fast.And because the imbalance of ability source distribution and the western and eastern's development, urgent need solves the bottleneck problem of high-power, the long distances of the energy.Though 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, carrier is all used at the novel overhead transmission line of research in countries in the world, to replace the traditional conventional steel reinforced aluminium conductor.The development of carbon fiber complex core aluminium stranded conductor, exploitation will greatly improve the conveying capacity of transmission line, and the carbon fiber complex core aluminium stranded conductor is compared with conventional steel reinforced aluminium conductor, has the following advantages:
1. intensity is big, and carbon fiber complex core aluminium stranded conductor intensity is 2 times of conventional steel reinforced aluminium conductor.
2. conductance is high, and the conductivity of carbon fiber complex core aluminium stranded conductor is 63.2%, improves 3-4% than conventional steel core aluminium hinge line conductivity.
3. low arc drop, carbon fiber complex core aluminium stranded conductor are compared with conventional steel reinforced aluminium conductor has significant low sag characteristic, and sag has improved the fail safe and the reliability of lead operation less than 1/10 of conventional steel reinforced aluminium conductor at normal temperatures.
4. high temperature resistant, the serviceability temperature of conventional steel reinforced aluminium conductor is below 100 ℃, and the carbon fiber complex core aluminium stranded conductor can effectively move under 180 ℃ of high temperature, and the short time can arrive 200 ℃.
5. in light weight, the proportion of carbon fiber plug is about 1/4 of steel, and carbon fiber complex core aluminium stranded conductor unit weight is about the 60%-80% of conventional steel reinforced aluminium conductor.
6. corrosion-resistant, the carbon fiber complex core aluminium stranded conductor is 2 times of conventional steel reinforced aluminium conductor useful life.
7. integrated cost is low.Because carbon fiber complex core aluminium stranded conductor capacity can strengthen operation, and characteristics such as tensile strength is high, sag is little, in light weight, the span between bar, the tower is increased; Highly reduce; Because intensity is high, can strengthen the span between bar, the tower, reduce bar, tower more than 20%.Same capacity line cost is lower than plain conductor integrated cost.
8. practice thrift the consumption of half aluminium.From protecting environment, energy savings, improving the human ecological environment aspect, has epoch making significance.
Though the carbon fiber lead has above plurality of advantages, can not monitor the temperature of lead in real time, take place easily to cause the phenomenon of whole cable bad because of electrical lead load increase causes to heat up.。
Summary of the invention
The purpose of the utility model provides a kind of carbon fiber photoelectricity composite cable that temp sensing function is arranged; Can carry out monitoring to the intensification situation of operating optoelectronic composite cable; In case find cable temperature overshoot value; Can in time reduce the electrical lead load, avoid the damage of cable, and have advantages such as the carbon fiber wire weight is light, intensity big, low arc drop.
To achieve these goals, the technical scheme of the utility model is:
A kind of carbon fiber photoelectricity composite cable with temp sensing function; Said cable from the center outwards be provided with successively carbon fiber complex core, conductor shield, insulating barrier, insulation screen, semi-conductive buffer water blocking layer, thermometric optical fiber, semi-conductive buffer water blocking layer, metal sheath layer, anticorrosive coat, plastic sheath and outside conductive electrode; Be provided with thermometric optical fiber between described insulating barrier and the restrictive coating, thermometric optical fiber in the shape of a spiral shape or snake laying in cable; Said thermometric optical fiber is selected from the armoured soft optical cable or stainless steel is strengthened optical fiber; Said carbon fiber complex core by epoxy resin, expansion multiple at the nano expanded graphite more than 100 times with strengthen the high-strength conducting composite material that the body carbon fiber forms and constitute; Said enhancing body carbon fiber is that carbon fiber wire, ceramic fibre silk and glass mat are processed by thermosetting resin cured typing, and said carbon fiber wire is the filament of being processed by polyacrylonitrile-based carbon fibre cellulose mixture carbon fiber.
The beneficial effect of the utility model is: not only have the complex function of optical fiber communication and electric power transfer concurrently, and can carry out monitoring to the temperature rise situation of operating optoelectronic composite cable, in case find cable temperature overshoot value; Can in time reduce the electrical lead load; Avoid the damage of cable, and have corrosion-resistantly, thermal coefficient of expansion is little; Low arc drop, the beneficial effect of light weight.
