Abstract
The utility model provides a kind of environmental-protection flame-retardant resistance to torsion wind energy power cable, belong to power transmission cable technical field used for wind power generation, be intended to solve existing power transmission cable structural design used for wind power generation unreasonable, be easy in application turn round damage, fracture, the problem of line body corrosion.The cable body that its adopts is the three-core cable body that forms of cable that three line hearts become the stranded conductor heart yearn of positive delta arrangement outside and are coated with insulating barrier, band is coated with in three-core cable external body, be filled with obturator between band and three-core cable body, band outside is coated with external sheath layer.It is simple and practical, and bulk strength is high, is applicable to the delivery of electrical energy of wind power plant.
Description
Technical field
The utility model belongs to a kind of power transmission cable used for wind power generation in field of cable technology.
Background technology
The energy is lifeblood and the blood of national development, and the conventional energy resource of extensive use such as oil, natural gas, coal and nuclear energy etc. are limited and can produce pollution.A kind of clean free of contamination regenerative resource of wind energy system, wind power generation plays an important role to the adjustment of electric structure and environmental protection.Due to the critical component that wind energy cable and power cable for wind power generation are wind power generation transmission electric energy, therefore, along with wind power generation development and technological progress, also more and more higher to the technical requirement of wind energy cable.In known technology, three respective independently conductor core wire outsides that existing wind energy cable mainly adopts are coated with the cable that insulating barrier is made, because wind energy cable operates mainly in outdoor, vertically unsettledly to lay, frequently reverse by wind action, what have also affects by sea wind, Long-term service temperature is in-40 DEG C ~+180 DEG C environment again, limit by its structure, its structural design is unreasonable, be easy in actual applications turn round damage, fracture, line body heavy corrosion, cause useful life short, change frequent, also the normal operation of wind power plant is often had influence on, make troubles to use.
Utility model content
In order to overcome the deficiencies in the prior art, solving existing power transmission cable structural design used for wind power generation unreasonable, being easy in application turn round damage, fracture, the problem of line body corrosion.The object of the utility model is to provide a kind of simple and practical, and bulk strength is high, fire-retardant resistance to torsion, corrosion-resistant, and application life is long, new type wind power generation power transmission cable easy to use.
The technical scheme in the invention for solving the above technical problem is:
A kind of environmental-protection flame-retardant resistance to torsion wind energy power cable, it is provided with: cable body, obturator, band, external sheath layer, cable body is the three-core cable body that forms of cable that three line hearts become the stranded conductor heart yearn of positive delta arrangement outside and are coated with insulating barrier, band is coated with in three-core cable external body, be filled with obturator between band and three-core cable body, band outside is coated with external sheath layer.
Above-mentioned environmental-protection flame-retardant resistance to torsion wind energy power cable, described stranded conductor heart yearn is the zinc-plated multiply tinned copper wire stranded conductor of anneal soft copper conductor.
When the utility model uses, according to designing requirement, carry out laying at wind energy generating plant.Product operating characteristic: 1, the rated operational voltage of cable is 0.6/1kV; 2, the long-term permission working temperature of cable conductor is-40 DEG C ~+180 DEG C; 3, mechanical strength is high, long-time running can lay in outdoor, vertically unsettled, can bear high drop, resistance to frequent torsion (driftage is to wind automatically), contact resistance greasy dirt, seawater corrosion resistance, vibration resistance etc.
Because the utility model design have employed technique scheme, efficiently solve existing power transmission cable structural design used for wind power generation unreasonable, be easy in application turn round damage, fracture, the problem of line body corrosion.Also show through for several times test result on trial, it compared with prior art, have simple and practical, bulk strength is high, fire-retardant resistance to torsion, corrosion-resistant, and the advantages such as application life is long, easy to use, are applicable to the delivery of electrical energy of wind power plant.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Accompanying drawing 1 is the structure diagram of the utility model embodiment.
In accompanying drawing, each label is: 1 stranded conductor heart yearn; 2 insulating barriers; 3 bands; 4 obturators; 5 external sheath layers.
Embodiment
Attached embodiment illustrated in fig. 1, the utility model is provided with: cable body, obturator 4, band 3, external sheath layer 5, cable body is the three-core cable body that cable that three line hearts become stranded conductor heart yearn 1 outside of positive delta arrangement to be coated with insulating barrier 2 forms, band 3 is coated with in three-core cable external body, be filled with obturator 4 between band 3 and three-core cable body, band 3 outside is coated with external sheath layer 5; Stranded conductor heart yearn 1 is the zinc-plated multiply tinned copper wire stranded conductor of anneal soft copper conductor; The Thermoplastic elastomer that it is base-material that insulating barrier 2 adopts with SBS (SBS) is also made for thermoplastic elastomer (Thermoplastic Rubber-TPR) type Insulation Material; External sheath layer 5 adopts TPUE (Thermoplastic Urethane-TPU) to make.
