The wind power generation cable is simple and reasonable in structure, easy in production and low in cost without pollution. The cable has high flexibility, elasticity, recoverability and tensile property, and can effectively prevent ultraviolet light.
Description
Technical field:
The utility model relates to a kind of cable technology, particularly a kind of construction of cable that is used for wind power generation field.
Background technology:
Wind energy more and more is subjected to the attention of countries in the world as a kind of regenerative resource of cleaning.Its amount of accumulateing is huge, and the wind energy in the whole world is about 2.74 * 109MW, and wherein available wind energy is 2 * 107MW, and is also bigger 10 times than the water energy total amount that can develop on the earth.The Chinese feature energy storage capacity is very big, distribution is wide, and only the wind energy content of land is about 2.53 hundred million kilowatts.Along with development of global economy, wind energy market also develops rapidly.Over nearly 5 years, wind energy market, world every year is all with 40% speed increment.Estimate in the following 20-25 that wind energy market, the world will increase progressively 25% every year.Now, the wind power generation cost dropped to 1980 1/5.Along with the development of technological progress and environmental protection cause, wind power generation will can be competed with coal fired power generation fully commercial.
Domestic wind-powered electricity generation industry development is rapider, also there is a big difference but with the development level of international wind-powered electricity generation industry, domestic wind power equipment mainly relies on import, externally dependence is strong, though wind power cost has descended much, but the advantage of comparing the thermoelectricity cost can't obviously be given prominence in a short time, and the development of wind-powered electricity generation industry also has a lot of hindering factors.Wherein the manufacturing expense of wind energy cable is not down one of key factor that hinders China's wind power generation development according to height yet.
The utility model content:
The utility model provides a kind of cost low at the above-mentioned existing existing problem of cable that is used for wind power generation, can uvioresistant, and the strong cable of environmental resistance.
In order to achieve the above object, the technical solution adopted in the utility model:
Wind electric power generation cable is made up of cable core, packed layer, band, inner sheath, armouring and oversheath; Described cable core thoroughly does away with stranded the forming of edge core by two, and insulated wire cores is made up of the conductor insulating barrier outer with being extruded in conductor, and fill by packed layer in the space between insulated wire cores; On the outer surface of insulated wire cores and packed layer, coat with the halogen-free flameproof band; Extrude one deck inner sheath on the band outer surface, this inner sheath covers one deck armouring outward, and extrudes one deck oversheath on the outer surface of this armouring.
Described conductor adopts copper wire or tinned copper wire, and adopts the 5th class formation of GB3956 standard code, thereby makes the cable flexibility good.
Described insulating barrier adopts crosslinked polyethylene insulation material to make, and by improved formulations, has effectively suppressed concentrating of space charge, prolongs the useful life of cable.
Described packed layer is the halogen-free flameproof oxygen barrier layer.
Described armouring is formed by metal wire knitted, and its intensity height, flexibility are good, has guaranteed the tensile property and the softness of cable.
Described sheath adopts high-strength polymer, and adds wide screener, thereby effectively suppresses the infringement of ultraviolet ray to cable cover(ing), makes cable have characteristics such as wear-resisting, resisting environmental stress and cracking.
The utility model that obtains according to technique scheme is rational in infrastructure simple, and the manufacturing is easy, cost is low, pollution-free.Cable has stronger flexibility, elasticity, restorability, pull resistance, can effectively suppress ultraviolet ray; Construction of cable compactness, rounding, safe in utilization, can satisfy the performance requirement of current wind energy cable fully, this product is exclusively used in domestic and international wind energy turbine set, has environmental benefit and economic benefit preferably.
Description of drawings:
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
Embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
The cable that is used for wind power generation, because environment of living in is special, this cable generally need reach following specification requirement:
(1) in order to reduce the investment that power transformation brings, wind power generation is used the 20kV DC generator usually, and this just requires the generator windings line to adopt the 20kV direct current cables.
(2) cable of used for transmission line also is a high voltage direct current cable.
(3) consider the field of employment of wind electric power generation cable, characteristics such as cable should have UV resistant, and flexibility is good, and environmental resistance is superior.
In order to reach above-mentioned specification requirement, the utility model has adopted structure as shown in Figure 1:
This cable is made up of cable core, packed layer, band, inner sheath, armouring and oversheath; Described cable core thoroughly does away with stranded the forming of edge core by two, insulated wire cores is made up of conductor 1 insulating barrier 2 outer with being extruded in conductor, conductor 1 adopts copper wire or tinned copper wire, and the 5th class formation of employing GB3956 standard code, thereby make the cable flexibility good, insulating barrier 2 adopts crosslinked polyethylene insulation material to make, and passes through improved formulations, effectively suppress concentrating of space charge, prolonged the useful life of cable.
Fill by halogen-free flameproof oxygen barrier layer 5 in space between insulated wire cores.
Coat with halogen-free flameproof band 3 on the outer surface of insulated wire cores and halogen-free flameproof oxygen barrier layer 5, extrude one deck inner sheath 4 on the outer surface of this band 3, this inner sheath covers one deck armouring 6 outward, and extrudes one deck oversheath 7 on the outer surface of this armouring; Armouring is formed by braided steel wire in this structure, and its intensity height, flexibility are good, has guaranteed the tensile property and the softness of cable; Inside and outside sheath adopts high-strength polymer, and adds wide screener, thereby effectively suppresses the infringement of ultraviolet ray to cable cover(ing), makes cable have characteristics such as wear-resisting, resisting environmental stress and cracking.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
