Abstract
The invention relates to a cable. A flexible wind energy cable comprises an insulating layer, an isolating layer and cable cores, wherein the number of the cable cores is at least two; each cable core comprises a fiber woven layer and an inner conductor; the cable cores are arranged in the isolating layer in parallel and are flat; and the inner conductor is formed by crossing a copper wire and a nylon fiber yarn. According to the technical scheme, the flexible wind energy cable has the advantages of high flexibility and bendability, capacity of moving frequently and the like.
Description
Technical field
The present invention relates to cable, be specifically related to a kind of flexibility cable.
Background technology
Wind energy cable is becoming the fastest cable kind of immediate development by the opportunity of clean energy resourcies such as national development wind energy.As the generation mode the most ripe, exploitation condition on the largest scale and commercialized development prospect of technology in the new forms of energy, Chinese wind power generation just is being explosive and is increasing.2005 to 2008, continuous 3 years of Chinese feature Denso machine capacity increased and surpasses 100%, during the new installed capacity of annual wind-powered electricity generation all be the summation in more than 20 year before this.2008; Chinese feature Denso machine capacity surpasses 5,000,000 kilowatts first, fulfiled the re-set target that National Development and Reform Committee proposes ahead of schedule, and the wind-powered electricity generation developing goal is improving constantly also; In 2006; The year two thousand twenty installation target of China is 3,000 ten thousand kilowatts, and media report is claimed recently, this target will by on be transferred to 10,000 ten thousand kilowatts to 15,000 ten thousand kilowatts.Along with the high speed development of wind-powered electricity generation, having become as the used for wind power generation cable of wind power plant auxiliary products has the cable of huge market potential new varieties, just by numerous cable enterprise's exploitations and put on market.One 50,000 kilowatts wind field, only the power cable just needs 40km.
The used for wind power generation cable is our usually said wind energy cable (the to call wind energy cable in the following text) engine room inside, cabin and the pylon top that are mainly used in wind generator system, change place of pylon bottom to tower under casing etc., is used for transferring electric power or signal.
For the requirement of wind energy cable is that cable can positive and negative rotation 720 degree, and product useful life is more than 30 years.Existing cable is difficult to reach above-mentioned requirements.
Summary of the invention
The objective of the invention is to, a kind of flexible wind energy cable is provided, to solve the problems of the technologies described above.
The technical problem that the present invention solved can adopt following technical scheme to realize:
Flexible wind energy cable comprises insulating barrier, separator, cable core, it is characterized in that said cable core has two at least, and said cable core comprises fibrage layer, inner wire, and said cable core is parallel and come in the said separator, and said insulating barrier becomes flat;
Said inner wire is knitted by copper wire and nylon fiber line strand and is formed.
Can adopt copper wire and nylon fiber line fine pith braiding structure strand to knit, under the prerequisite that guarantees ampacity, this structure makes conductor have certain retractility and intensity, and it is good to have flexibility, and tensile strength is good, and is in light weight.
Said flexible wind energy cable, because whole flexible cable is a flat, the bending of not easy fracture, so flexible cable, mobile with more convenient.
The composite material that said insulating barrier adopts rubber and polyvinyl chloride to constitute.Said composite material not only has high flexibility, also has oil resistant and characteristics such as wear-resisting simultaneously, makes made flexible cable be applicable to the frequent occasion that moves.
Said separator is isolated cable core and insulating barrier, and cable core evenly is arranged in the separator closely, the damage of protection cable core.
The fibrage layer that it is fiber that said fibrage layer can adopt cotton synthetic fibre silk; Adopt cotton synthetic fibre silk both to increase the mechanical strength of flexible cable; Can also make flexible cable quite soft; Have the high ventilation performance, said fibrage layer also can adopt the fibrage layer of diamagnetic metallic fiber braiding, makes it have the advantage of protection and electromagnetic shielding.
Said inner wire by copper wire with spin the synthetic fibre skein silk and knit and form; Can adopt copper wire and spin synthetic fibre silk fine pith braiding structure strand and knit; Under the prerequisite that guarantees ampacity, this structure makes conductor have certain retractility and intensity, has good flexibility, bendability; Good tensile strength makes flexible cable can adapt to different bending motions and moves with frequent.
Beneficial effect: owing to adopted technique scheme, the present invention to have flexibility, good bandability, advantage such as can frequently move.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a kind of structural representation of inner wire of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, further set forth the present invention below in conjunction with concrete diagram.
With reference to Fig. 1, flexible wind energy cable comprises insulating barrier 1, separator 2, cable core 3, and cable core 3 has two at least, and cable core 3 comprises fibrage layer 31, inner wire 32, and cable core 3 is parallel and come in the separator 2, and insulating barrier becomes flat.The quantity of cable core 3 can be set as required, with reference to Fig. 1, can select three cable cores closely and come in the separator 2, because whole flexible cable is a flat, so the bending of flexible cable, moves more convenient.Inner wire 32 is knitted by copper wire and nylon fiber line strand and is formed.
The composite material that insulating barrier adopts rubber and polyvinyl chloride to constitute.Composite material not only has high flexibility, also has oil resistant and characteristics such as wear-resisting simultaneously, makes made flexible cable be applicable to the frequent occasion that moves.Separator is isolated cable core and insulating barrier, and cable core evenly is arranged in the separator closely.The fibrage layer that it is fiber that fibrage layer 31 can adopt cotton synthetic fibre silk; Adopt cotton synthetic fibre silk both to increase the mechanical strength of flexible cable; Can also make flexible cable quite soft; Have the high ventilation performance, fibrage layer 31 also can adopt the fibrage layer of diamagnetic metallic fiber braiding, makes it have the advantage of protection and electromagnetic shielding.
With reference to Fig. 2; Inner wire by copper wire 4 with spin synthetic fibre silk 5 strands and knit and form, can adopt copper wire 4 and spin synthetic fibre silk 5 fine pith braiding structures strand and knit, under the prerequisite that guarantees ampacity; This structure makes conductor have certain retractility and intensity; Have good flexibility, bendability, good tensile strength makes flexible cable can adapt to different bending motions and moves with frequent.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection range to be defined by appending claims and equivalent thereof.
