Abstract
The utility model discloses a power cable for wind power generation, which comprises a plurality of conductors and insulating layers, wherein each conductor is coated with the insulating layer; filler is filled among the outside gaps of the conductors and the insulation layers; belting layers are coated outside the insulating layers; jacket layers are coated outside the belting layers; the conductor material is drawn by an oxygen-free copper rod and has the cross section of 1.0-400mm2; the insulating material adopts silicone rubber; and the jacket layers adopt thermoplastic polyurethane elastomer. The utility model has the advantages of simple structure and favorable strength, is convenient for manufacture and easy for laying, resists torsion and bending at low temperature, moisture, cold, salt haze, oil, ultraviolet rays and high temperature and is flexible and movable; and in addition, the utility model can meet the requirement that basic performances of products can be maintained under the environments of cold whether, hydrolysis or mechanical damage, is green and environment-friendly and embodies the idea of low-carbon society.
Description
Technical field:
The utility model relates to the power cable field, relates in particular to a kind of used for wind power generation power cable.
Background technology:
The green tide that current energy revolution and low-carbon economy are the theme have swepts the globe, and wind-powered electricity generation is enormously potential new forms of energy industry.In September, 2009, China represented on U.N. climate change summit, win the year two thousand twenty China " non-fossil energy " and account for primary energy consumption proportion and reach 15%, in the United Nations's weather conference, propose the year two thousand twenty China per GDP carbon emission and on basis in 2005, reduce by 40%～45% target.
The wind energy resources of China occupies the third place in the world, and only the available wind energy resources total amount in land promptly reaches 2.53 hundred million kilowatts, roughly is equivalent to 250 million kilowatt fossil capacities.The available wind energy density of coastal area of southeastern China surpasses 200W/m
2, the available wind energy density of offshore islands reaches 300W/m
2More than, the available wind energy utilization is for up to more than the 6000h.Northeast and area, Inner Mongol available wind energy density are at 200～300W/m
2, whole year effective wind duration, effective energy output of every square metre of area reached more than the 245kWh more than 4000h.But advanced country compares with wind-powered electricity generation, compares with huge wind energy reserves, and Chinese feature Denso machine capacity is too little really, and the wind energy turbine set single-machine capacity that has built up is also less than normal, on average has only the 591.79kW/ platform.Therefore, the Chinese feature electric industry also is in the starting stage, does not satisfy the demand in market far away.So wind power plant is still very big with the potentiality of all kinds of cables in the long term.
The used for wind power generation special cable since long-time running in outdoor, vertically unsettledly lay, frequently reverse (positive and negative around each for once, number of times is no less than 3600 times antitorque commentaries on classics performance), contact greasy dirt (part), seawater corrosion (particular surroundings), require its mechanical strength height, anti-turning round (softness), vibration resistance and oil resistant etc., be used in the cable also low temperature resistant (40 ℃) of cold district in addition.Because the environment of wind power generation is abominable, blower fan is longer service life, and cable is higher to the performance requirement of cable with characteristics such as the continuous rotations of blower fan, all the time, all is a large amount of dependence on import.
At present, the research and development of used for wind power generation cable also belong to the starting stage, progressively ripe along with domestic special cable production technology in recent years, and domestic wind-powered electricity generation has begun gradually like product outside the subrogate country with cable.
The utility model content:
The purpose of this utility model provides a kind of used for wind power generation power cable, and it is local under subzero 60 ℃ to have solved the polyvinyl chloride insulation power cable, and the cable embrittlement can not be installed and frequent torsion problem.
Technical scheme of the present utility model is as follows:
A kind of used for wind power generation power cable, comprise many conductors, insulating barrier, it is characterized in that: described every conductor is wrapped with insulating barrier, be provided with filler as filling between many Inside and Outside of Conductor side clearances and the insulating barrier, described insulating barrier is wrapped with belting layer, and belting layer is wrapped with restrictive coating.
Described used for wind power generation power cable is characterized in that: described conductor material adopts oxygen-free copper bar to draw, and area of section is 1.0～400mm
2, described insulating layer material adopts silicon rubber, and described restrictive coating material adopts TPUE.
Material that the utility model adopts is:
(1) conductor: conductor material is that oxygen-free copper bar draws the lead that forms.Conductor should adopt the 5th kind of copper or the tin-coated copper conductor of stipulating among the GB/T3956.Cross-sectional area of conductor is generally 1.0～400mm
2
(2) insulation: according to environment for use and cable normal operating temperature, select silicon rubber as insulating material, because insulating requirements has certain mechanical property, common silastic material mechanical property is relatively poor, especially tear resistance is poor, can not satisfy the normal mounting operation of cable,, select for use tension to tear the silicon rubber insulation material and can satisfy serviceability through test, checking.Silastic material has good pliability, make the working temperature of cable bring up to 180 ℃ Celsius, improve the voltage-resistent characteristic of product simultaneously, also have very high thermal endurance, excellent cold resistance, excellent electric insulation performance, good aging properties, excellent oil resistance, and nontoxic odorless.It is a kind of desirable wind-powered electricity generation cable insulation clad material.Insulation should closely be extruded on the conductor, and section does not have visible bubble of eyesight and impurity, the outward appearance rounding and easily and conductor peel off.
(3) stranding and cable core are wrapped: cable stranding outermost layer direction of lay is a dextrad, and insulated wire cores should twist together.The stranded lay ratio of stranding outermost layer should be not more than 12 times; Twining package tape is selected Halogen material twining package tape for use.
(4) sheath: sheath adopts TPUE (TPU) material.Jacket surface should be smooth, rounding, color and luster basically identical, and section should not have visible bubble of eyesight and impurity.
The utility model has the advantages that:
Of the present utility model simple in structure, cable intensity is good, and is easily manufactured, lays easily; Low temperature is anti-to be turned round, the antitorque cold-resistant fire-retardant extraordinary flexible electric power cable series of products of used for wind power generation of anti-curved, the moisture-proof of low temperature, cold-resistant, salt spray resistance, oil resistant, UV resistant, characteristics such as high temperature resistant, soft removable, can satisfy the product demand that keeps Essential Performance Requirements under the environment of weather, hydrolysis or mechanical damage in cold; Environmental protection, having embodied is the theory of low-carbon (LC) society.
