Abstract
The utility model relates to an improvement of a combined optical fiber conductor. The combined optical fiber conductor is characterized in that optical fibers and/or optical cables with a protecting tube are arranged in the center of a stranded aluminum conductor, so as to form a diameter-expanding aluminum conductor. With the sleeve tube structure, the optical fibers have a certain excess length inside the sleeve tube, which facilitates overhead installation, prevents the optical fibers from being broken during overhead line construction and in case of temperature rise, sag increase or wind action, and effectively protects the internal optical fibers. Besides, the optical fibers with the sleeve tube structure can be conveniently pulled out for repair and replacement. The optical fiber unit, as the diameter-expanding structure of the aluminum conductor, achieves the combination of the conductor and the optical fibers and forms the diameter-expanding unit, so that the extra diameter-expanding unit is not needed and the conductor can be used in the medium/high power transmission lines. Furthermore, the diameter-expanding conductor increases the current-carrying capacity of the conductor and reduces the skin effect. The combined optical fiber conductor is applied to both power transmission and signal transmission, and can monitor the operating condition of the line to ensure circuit security.
Description
Technical field
Utility model is the improvement to the combination of fiber-optic lead, relates in particular to a kind of in light weightly, and cost is low, is fit to mesohigh and above transmission line, can transmission of electric energy again can transmission signals the combination of fiber-optic lead.
Background technology
There is 70% family in China in the rural area, and China territory is vast, and it is very scattered again that the rural area distributes, and then to set up cost separately bigger because of optical cable for broadband internet and cable TV, is difficult to spread to rural area particularly mountain area, northwest village.Set up cost separately for saving, prior art have by with optical cable in advance in cable, constitute band optical fiber power cable, for example Chinese patent CN2708456 optoelectronic composite cable has optical cable core and packed layer between the electric power core.Chinese patent CN2689409 has the optical fiber power cable, stranded or when making electric-cable core, twist into optical fiber simultaneously or is installed with ferrule at electric power core gap location.Yet the power cable of existing band optical fiber all adopts copper conductor, and its core is from great, and the built on stilts sag that lays causes that easily optical fiber breaks, and therefore can not be used for built on stilts laying, and can only be used for buried-pipe laying.And buried-pipe laying, not only self cost is bigger, be about about 2 times of overhead wire, and laid down cost height, be 3～5 times of overhead wire approximately, the complex-terrain laid down cost is higher, so such cable generally can only be used for the city and lay, and is difficult to be generalized to especially distance outlying rural area far away, vast rural area.
The applicant formerly applies for a patent 200520074008.9, with the parallel boundling multicore aerial insulated cable of forming of some aluminium conductors, has in wherein at least one core to include the fiber unit of non-magnetic conductive metal pipe in addition.Though adopt aluminium conductor to alleviate weight, and simplified cable laying operation and laid down cost.But bundle structure when optical fiber or optical cable run into fault, is difficult to realize maintenance; Secondly, owing to adopt insulation system, incorporate into and be with the optical cable of protection tube to increase external diameter, thereby increased the insulating material consumption; Its three, bunched aerial insulated cable generally is only applicable to can not satisfy usually remote conveying circuit requirement 35kv and above middle pressure and high pressure electric line in 1kv and the following transmission line.
Above-mentioned deficiency still has is worth improved place.
The utility model content
The utility model purpose is to overcome above-mentioned the deficiencies in the prior art, provides a kind of in light weight, and cost is low, is fit to the combination of fiber-optic lead of mesohigh and above transmission of electricity.
The utility model purpose realizes that main improvement is directly to utilize the optical fiber of band protective casing and/or optical cable as the hole enlargement unit of aerial condutor, makes the naked aluminium stranded conductor of hole enlargement, thereby overcomes above-mentioned prior art deficiency, realizes the utility model purpose.Specifically, utility model combination of fiber-optic lead comprises stranded transmission of electricity aluminum conductor, it is characterized in that there is the optical fiber and/or the optical cable of band protection tube at stranded aluminum conductor center, constitutes the hole enlargement aluminum conductor.
Utility model is said:
The hole enlargement fiber unit is meant the fiber unit of being with protection tube, uses as hole enlargement, and can be a fiber unit as required, also can be the stranded arrangement of several fiber units.Optical fiber protective tube, same prior art can be a non-metallic pipe, also can be metal tube.Be the bending property of raising stranded conductor, optical fiber protective tube, better adopting to roll has the embossing of annular line pipe.For making built-in fiber that certain surplus be arranged, adapt to and set up stretch-draw, and heat expansion increase sag and wind loading rating, do not make optic fibre force, a kind of better is that optical fiber protective tube has relatively large bore, and pine is placed in outside the optical fiber, and promptly managing inner fiber has certain loose surplus.
Outer stranded aluminium conductor can be the aluminium round conductor, also can be various molded lines conductors.In addition, can also between stranded aluminium conductor layer and optical fiber tube, increase the hole enlargement layer again, to obtain bigger hole enlargement effect.
In addition, be laid in the occasion that frequently contacts with the crowd, use for greater safety, can also extruded insulation.
Utility model combination of fiber-optic lead, with respect to prior art, make the hole enlargement unit of stranded conductor owing to adopt optical fiber with well, sleeve structure not only makes optical fiber can leave certain surplus length in sleeve pipe, be used for built on stilts laying, increase or wind-force is done the time spent and can not broken optical fiber at lead stringing and temperature rising sag, effectively protected built-in fiber; And sleeve structure optical fiber, maintenance easily can be by pulling out maintain and replace.Fiber unit had both made as the hole enlargement structure of aluminum conductor that lead had made up optical fiber, constituted the hole enlargement unit again, added the hole enlargement unit in addition thereby omit, and made lead can be used for middle and high transmission line; Secondly, expanded conductor has also improved the lead current capacity simultaneously, has reduced kelvin effect.The combination of fiber-optic lead, both electric energy transmittings, transmission signals again again can monitoring circuit ruuning situation, guarantees circuit safety.Utility model combination of fiber-optic lead is made simply, and cost is low, sets up cost with common aerial condutor, is a kind of novel built on stilts combination of fiber-optic lead.
Optimize specific embodiment below in conjunction with several; utility model essence is further understood in exemplary illustration and help; but the embodiment detail only is for utility model is described; do not represent utility model design whole technical schemes down; therefore should not be construed as the total technical scheme of utility model is limited; some are In the view of the technical staff; the unsubstantiality that does not depart from the utility model design increases and/or change; for example change or replace, all truely use novel protected scope so that technical characterictic with same or similar technique effect is simple.
