Abstract
The invention discloses a rubber jacketed flexible cable for single-core medium-voltage wind power generation. The voltage class of the rubber jacketed flexible cable ranges from 6kV to 35kV. The rubber jacketed flexible cable comprises a power line core conductor arranged in the center of the cable, the outer side of the power line core conductor is wrapped by a conductor shielding layer, an insulation layer and an insulation shielding layer in sequence in a three-layer co-extrusion mode, a metal braided shielding layer is braided outside the insulation shielding layer, and the outer side of the metal braided shielding layer is wrapped by an outer protection sleeve in an extrusion mode. The rubber jacketed flexible cable is suitable for being used in a megawatt fan and has the advantages of being resistant to low temperature and cracking and long in service life, and meanwhile compared with a cable which is provided with the identical section and used for low-voltage wind power generation, the rubber jacketed flexible cable has the advantages of being high in power, large in current-carrying capacity, large in electric energy conveying capacity, capable of reducing the number of adopted cables, capable of lowering cost, and convenient to maintain.
Description
?
Technical field
The present invention relates to electric wire field, in especially a kind of single core, press rubber jacketed flexible cable for wind power generation.
Background technology
The wind-powered electricity generation industry development speed of China is very swift and violent, the installation total capacity of China Wind Power generating equipment is the first in the world at present, technological accumulation and fund input through wind power equipment for many years, the domestic wind power equipment level of production improves constantly, the rucial scientific and technological problems of Megawatt fan are broken through, existing such blower fan comes into operation, along with coming into operation of such blower fan, for the important auxiliary products of wind turbine generator---cable for wind power generation also rests on former technical merit.The cable using on existing blower fan mostly is low pressure cable for wind power generation, and its electric pressure is 0.6/1kV.
The electric energy that the blower fan of MW class produces is more, and therefore for transmission of electric energy, the cable that the low-voltage of using in such blower fan, heavy in section cable for wind power generation are used than other wind turbine generator is many.Mainly have the shortcoming of following several respects:
1, the prime cost of cable is copper, along with using the increase of number of cables, can increase the cost of wind-powered electricity generation enterprise,
2, the increase of number of cables, makes the maintenance of cable become difficult;
3, the power of fan of MW class is large, and instant starting currents is large, and low pressure cable for wind power generation voltage is compared with middle pressure cable for wind power generation, and little with power in the situation of cross section, ampacity is less, and power delivery amount is few;
4, common insulating material does not belong to low medium second the third, can cause the high use that affects cable of dielectric loss due to insulating material.
Summary of the invention
The present invention presses rubber jacketed flexible cable for wind power generation for the problem that solves prior art and exist provides in a kind of single core, be suitable for using in Megawatt fan, there is low temperature resistant, cracking resistance, the advantage that life-span is long, compares that to have power large simultaneously with the low pressure cable for wind power generation in same cross section, ampacity is larger, power delivery amount is large, can reduce the use amount of cable, not only can reduce cost, and have easy to maintenance.
For solving above technical problem, in a kind of single core of the present invention, press rubber jacketed flexible cable for wind power generation, comprised the power line core conductor that is positioned at cable center, outside power line core conductor, by three-layer co-extruded mode, extrude successively conductor shield, insulating barrier, insulation screen, the outer braided metal woven shield of insulation screen, metal knitted screen extrudes oversheath outward.
Further improve, described power line core conductor is twisted and forms again again by the first synnema of six class monofilament, and synnema pitch ratio is 18 times, and twisting again pitch ratio is 12 times.
Further improve, described power line core conductor adopts six class monofilament structures, 35mm again
2with lower section, adopt 0.2mm monofilament, 50 mm
2～150 mm
2adopt 0.3 mm monofilament, 185mm
2with upper section, adopt 0.4mm monofilament.
Compared with prior art, beneficial effect of the present invention:
(1) flexility:
What original conductor adopted is five class lay configuration, 50mm
2with lower section, adopt 0.4mm monofilament, 70mm
2with upper section, adopt 0.5mm monofilament; Now adopt six class monofilament structures, 35mm
2with lower section, adopt 0.2mm monofilament, 50 mm
2～150 mm
2adopt 0.3 mm monofilament, 185mm
2with upper section, adopt 0.4mm monofilament, the external diameter of monofilament is less, and pliability is better.
(2) warp resistance function:
Original general 25 times of synnema external diameters of synnema pitch that adopt, twist again pitch and are generally 14 times and twist again external diameter.The existing general 18 times of synnema external diameters of synnema pitch, twist again pitch and are generally 12 times and twist again external diameter.Stranded tightr of present conductor, rounding property is better, and conductor is not easy when crooked to occur whole burst of loose situation, and conductor flexibility, good bandability, improved greatly the resistance to performance of turning round of cable.
(3) low temperature resistant, cracking resistance function
In rubber-covered and protective cover material, add low temperature resistant plasticizer, and increase pine tar/steam cylinder oil and coupling agent, thereby realized low temperature resistant, the cracking resistance function of cable.
(4) low dielectric loss insulation
The insulating material of cable is low dielectric loss insulating material, and cable in use dielectric loss is low, so cable physical life is long.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further elaborated:
As shown in Figure 1, in a kind of single core of the present invention, press rubber jacketed flexible cable for wind power generation, comprised the power line core conductor 1 that is positioned at cable center, outside power line core conductor 1, by three-layer co-extruded mode, extrude successively conductor shield 2, insulating barrier 3, insulation screen 4, the outer braided metal woven shield 5 of insulation screen 4, the outer oversheath 6 that extrudes of metal knitted screen 5.Described power line core conductor 1 is twisted and forms again again by the first synnema of six class monofilament, and synnema pitch ratio is 18 times, and twisting again pitch ratio is 12 times.
Above-mentioned is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvement and adjustment, these improvement and adjustment also should be considered as protection scope of the present invention.
