Abstract

The utility model discloses a kind of wind power generation lightning protection flexible cable, on the one hand the setting of first screen layer and secondary shielding layer can prevent the electromagnetic interference between conductor, on the other hand can be that the powerful Electromagnetic Field generated generates the double-deck buffer action to lightning stroke;The setting of ground plane, when being struck by lightning, the instantaneous calorific value meeting very little of ground plane avoids cable from being blown;The bituminous coating being arranged outside nanocomposite elastomer sheath, can effectively anti-corrosion and the aging for preventing nanocomposite elastomer sheath;External several triangular hills being arranged of bituminous coating, when use, cable is easily fixed on wall, on the ground or on other objects after fixation hole can be passed through by rivet, since the cable majority is for open air and to carry out lightning protection, so the safety that cable uses can be improved by being fixed;Using nanocomposite elastomer sheath, the performances such as impact resistance, cold-resistant, anti-tensile strength, anticorrosion can be increased.

Description

A kind of wind power generation lightning protection flexible cable
Technical field
The utility model belongs to clean energy technology field, and in particular to a kind of wind power generation lightning protection flexible cable.
Background technique
Wind-driven generator is generally located on the highland in field, and fan blade is easily struck by lightning;Existing general lightning protection Technology is focused on by how lightning current quickly to be introduced the earth when being struck by lightning, and is reduced as far as importing equipment by thunder and lightning Electric current, to the maximum extent ensure equipment and personnel safety, make loss be reduced to the smallest degree;In the design mainly by leaf Piece arrester, blade interior lead the composition such as thunder channel, complete machine Grounding;With the increase of Wind turbines single-machine capacity, blade Length is also being continuously increased, and some blade diameters are up to more than 150 rice, in addition blower fan pylon constantly increases, so that blade is more Far from ground;There is no the researchs that the cable for wind-driven generator carries out lightning protection test at present.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of wind power generation lightning protection flexible cable.
To achieve the above objectives, the present invention adopts the following technical solutions: a kind of wind power generation lightning protection flexible cable, including It is compound to be successively enclosed with insulated wire cores wrapping layer, polyvinyl chloride outside the insulated wire cores from inside to outside for several insulated wire cores Layer, insulating layer, first screen layer and glide lamella, the polyvinyl chloride composite layer with a thickness of 0.30~2.00mm, the sliding Layer is the macromolecule material film layer of low friction coefficient, and several insulated wire cores mutually twist together;It is described it is several with The outside of insulated wire cores include from inside to outside composite fire layer, inner sheath, soft structure lightning protection layer, secondary shielding layer, ground plane, Nanocomposite elastomer sheath and bituminous coating, the soft structure lightning protection layer are wire and fiber filament mixed weaving layer, the two Orthogonal weave reticulates, and is provided with high resiliency gasket for packing and fiberglass plastic in the gap between several insulated wire cores Ball, both the high resiliency gasket for packing and fiberglass plastic ball are in be staggered;If the outside of the bituminous coating is provided with Dry triangular hill, several triangular hills are provided on each triangular hill in being symmetrical arranged two-by-two Fixation hole.
Further, the quantity of the insulated wire cores is at least three.
Further, it is described it is netted for trapezoidal netted, triangular mesh or hexagon it is one of netted.
Further, the quantity at least two of the triangular hill.
Further, the fixation hole is one of peach-shaped fixation hole, six prismatic fixation holes or fan-shaped fixation hole.
By adopting the above technical scheme, beneficial effects of the present invention:
On the one hand a kind of wind power generation lightning protection flexible cable, the setting of first screen layer and secondary shielding layer can prevent from leading On the other hand electromagnetic interference between body can be that the powerful Electromagnetic Field generated generates the double-deck buffer action to lightning stroke;Ground connection The setting of layer, when being struck by lightning, the instantaneous calorific value meeting very little of ground plane avoids cable from being blown;Nanocomposite elastomer The bituminous coating being arranged outside sheath, can effectively anti-corrosion and the aging for preventing nanocomposite elastomer sheath;Bituminous coating External several triangular hills being arranged, in use, cable easily be fixed after fixation hole can be passed through by rivet In on wall, on the ground or other objects on, since the cable majority is for open air and to carry out lightning protection, so being fixed The safety that cable uses can be improved;Using nanocomposite elastomer sheath, impact resistance, cold-resistant, tension Zhang Qiang can be increased The performances such as degree, anticorrosion;Its with it is light it is soft, conduct electricity very well, that corrosion resistance is strong, it is fixed to be easy to, manufacturing cost is low is excellent Point.
