Description
Technical field:
The utility model relates to control cable, relates in particular to a kind of control cable of used for wind power generation.
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, won the year two thousand twenty China " non-fossil energy " and accounted for primary energy consumption proportion and reach 15%: propose the year two thousand twenty China per GDP carbon emission and reduce by 40%～45% target in the United Nations's weather conference on basis in 2005.
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, China also belongs to the starting stage to the research and development as the used for wind power generation cable of one of wind-powered electricity generation critical elements.Because the performance requirement of used for wind power generation cable is higher, a large amount of always dependence on import of state's Related product and costing an arm and a leg still.But progressively ripe along with domestic special cable production technology in recent years, 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 control cable of used for wind power generation, and it is local under subzero 60 ℃ to have solved the polyvinyl chloride insulation control cable, and the cable embrittlement can not be installed and frequent torsion problem; In addition, improved the cable pliability, made the working temperature of cable bring up to 180 ℃ Celsius,, improved the intensity of cable keeping cable to have under the situation of pliability preferably.
Technical scheme of the present utility model is as follows:
A kind of control cable of used for wind power generation, comprise many conductors, insulating barrier, described conductor outer wrapping insulating barrier, insulating barrier outer wrapping screen one, the conductor outside of many parcel screens one is enclosed with belting layer, it is characterized in that: described belting layer outer wrapping screen two, screen two outer wrapping restrictive coatings.
The control cable of described used for wind power generation, it is characterized in that: described conductor material is that oxygen-free copper bar draws the lead that forms, described insulating layer material adopts silicon rubber, described screen adopts the tinned copper wire shielding, shielding density is greater than 80%, 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 0.75～2.5mm
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: the common core number of control cable is more, keeps the cable rounding the most key.Insulated wire cores should twist together, and cable stranding outermost layer direction of lay is a dextrad.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) shielding: the tinned copper wire braid shielded is adopted in shielding, and shielding density is greater than 80%.
(5) sheath: sheath adopts TPUE (TPU) material.
The utility model has the advantages that:
Of the present utility model simple in structure, cable intensity is good, easily manufactured, lay easily, advantages of good shielding performance: low temperature is anti-to be turned round, anti-curved, the moisture-proof of low temperature, cold-resistant, salt spray resistance, oil resistant, UV resistant, high temperature resistant, softness characteristics movably, satisfies simultaneously under the environment of weather, hydrolysis or mechanical damage in cold to keep the cable key property; Environmental protection.
