Abstract
The utility model relates to a transmission cable for wind power farms, which comprises an external protection layer and three internal wires wrapped in the external protection layer, wherein the external protection layer consists of an outer sheath, a PE (Poly Ethylene) sheath, an aluminum-plastic composite belt and a wrapping belt from the outside in, and each internal wire consists of a metallic shielding layer, an insulation shielding layer, a water-resistant tree crosslinked polyethylene insulation layer, a conductor shielding layer and a conductor from the outside in. According to the transmission cable for the wind power farms, a cable structure is designed, and high-quality water-resistant tree insulation material layers and corrosion-resistant polyvinyl chloride butyronitrile composite sheath materials are adopted, so that the low temperature resistance, water resistance and corrosion resistance of the transmission cable are realized. The transmission cable can replace the ordinary crosslinked cable to be applied to power transmission networks of the wind power farms, the service life of the cable is prolonged, and the safety and reliability of the networks are improved. The realization of performances, the producing practicability, the reasonable cost control and other factors are fully taken into consideration for the design of the cable, and convenience is brought for the production and realization of a product.
Description
Technical field
The utility model belongs to the cable technology field, relates to a kind of transmission cable, especially a kind of wind power plant transmission cable.
Background technology
Wind energy is subject to the favor of countries in the world more and more as a kind of renewable resource, and wind power generation is becoming in the world fastest-rising new forms of energy project.At present wind power generation is widely used and obtains a lot of experiences in countries such as Germany, Denmark, the U.S..The Wind Energy In China reserves are abundant, it is wide to distribute, and the development wind-powered electricity generation is had wide market prospects, and China has implemented to promote the national wind-powered electricity generation royalty right demonstrative project of Wind Power Development simultaneously, the regulation blower fan localization rate of parts and components is not less than 70%, and general assembly must be finished at home.Country has proposed the year two thousand twenty wind-powered electricity generation and has realized total installed capacity 3,000 ten thousand kW.But from present development speed, the wind power generation installed capacity meeting of China surpasses the predetermined development plan of country out and away.
Wind power plant is built desert, grassland or Degraded Pastures and the Southern Coast area in the north usually.Wind energy turbine set is because environment is harsh, the characteristics such as that the transmission cable of use requires to possess is low temperature resistant, waterproof.And the transmission cable that present many wind energy turbine set is used remains traditional crosslinked cable, can not fully satisfy the instructions for use of environment, in cable laying, use procedure, the sheath cracking can occur, and the problems such as cable water inlet affect the safety in utilization of cable.For this reason, according to the instructions for use of wind energy turbine set transmission cable, developed the transmission cable that is incorporated into the power networks that is applicable to wind energy turbine set.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of wind power plant transmission cable is provided, this transmission cable is according to the needs of environment for use, adopt water-tree retardant insulating materials and polyvinyl chloride butyronitrile compound oversheath, and by rational structural design, make cable have excellent mechanical performance, and intensity is high, extrusion performance is good, and environmental stress resistance is good, can lay at low temperatures.
The purpose of this utility model solves by the following technical programs:
This wind power plant transmission cable comprises external protection and is wrapped in three interior inside conductors of external protection; Described external protection is comprised of oversheath, PE sheath, aluminium-plastic tape, band from outside to inside; Every inside conductor is comprised of metal screen layer, insulation screen, the crosslinked polyetylene insulated layer of anti-water tree, conductor shield and conductor respectively from outside to inside.
Above-mentioned three inside conductor triangularity clusters are arranged in the external protection.
Further, in the space between described external protection and inside conductor the material water-proof material filler is arranged.
The utlity model has following beneficial effect:
Wind power plant transmission cable of the present utility model passes through the design to the construction of cable, and selects the water-tree retardant insulating materials layer of high-quality and resistance to low temperature, block-water performance and the decay resistance that corrosion resistant polyvinyl chloride butyronitrile compound sheath material has been realized cable.Can replace common crosslinked cable to be applied to prolong the useful life of cable in the electric power transmission network of wind energy turbine set, improve the security reliability of network.Cable fully takes into account the factors such as the realization of performance, the feasibility of production, rational cost control in design, is convenient to production and the realization of product.The development and production of product meets the industrial development direction of country.
Description of drawings
Fig. 1 is the cross-sectional structure schematic diagram of the utility model cable.
Wherein: 1 is conductor; 2 is conductor shield; 3 is insulating barrier; 4 is insulation screen; 5 is metal screen layer; 6 is the material water-proof material filler; 7 is band; 8 is aluminium-plastic tape; 9 is the PE sheath; 10 is oversheath.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1, wind power plant transmission cable of the present utility model comprises external protection and is wrapped in three interior inside conductors of external protection; Described external protection is comprised of polyvinyl chloride butyronitrile compound oversheath 10, PE sheath 9, aluminium-plastic tape 8, band 7 from outside to inside; Every inside conductor is comprised of metal screen layer 5, insulation screen 4, the crosslinked polyetylene insulated layer 3 of anti-water tree, conductor shield 2 and conductor 1 respectively from outside to inside.Described three inside conductor triangularity clusters are arranged in the external protection.Material water-proof material filler 6 is arranged in the space between described external protection and inside conductor.
In the design of the construction of cable of the present utility model, special circumstances for the environment for use of cable, carried out considering of each side, fully take into account construction of cable block-water performance, the low temperature resistant cracking of sheath, the sheath decay resistance, the realization difficulty of technique, the many factors such as rational manufacturing cost.The anti-water crosslinked polyetylene insulated layer of tree (TR-XLPE) that the utility model adopts DOW Chemical to produce, TR-XLPE have high degree of purity and excellent water tree resistant property, can reduce the generation of water tree in the insulating barrier, delay the growth of water tree.Also have the identical mechanical and physical performance of plain edition crosslinked polyethylene insulation material and electric property, have low dielectric constant and dielectric loss.And the utility model adopts polyvinyl chloride butyronitrile compound oversheath 10, and polyvinyl chloride butyronitrile compound protective cover material has good acid-alkali-corrosive-resisting ability and resistance to low temperature, particularly at low temperatures, has excellent mechanical performance.And intensity is high, and extrusion performance is good, and environmental stress resistance is good, can lay at low temperatures and use.
