Copper litz wire to be or polyvinyl chloride cable ground connection, but along with the increase of installed capacity, and the development of offshore wind farm, this
Transmission capacity and the Seawater durability of planting lightning-protective cable will be unable to meet requirement.
Therefore those skilled in the art endeavour to develop the Wind turbines lightning-protective cable that a kind of impact resistance electric current is high.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is to provide a kind of impact resistance electric current
High Wind turbines lightning-protective cable.
For achieving the above object, the invention provides a kind of Wind turbines lightning-protective cable, including leader cable, leader cable passes through
Metal connecting tube is provided with branch cable, and branch cable is identical with the structure of leader cable；Metal connecting tube is arranged in insulation booth body；Absolutely
It is injected with insulating cement in edge box body；
Leader cable includes center conductor, and the outside of center conductor is provided with the first conductor, and the first conductor includes six first
Conductor thread core, each first conductor thread core is stranded with center conductor；First conductor is outside equipped with the second conductor, and the second conductor includes ten
Two the second conductor thread cores, each second conductor thread core and the first conductor strand；Internal shield, interior screen it is provided with outside second conductor
The outside covering layer is provided with insulating barrier, and the thickness of insulating barrier is 4.8mm-5.2mm.
For improving the impact resistance electric current of Wind turbines lightning-protective cable, the most for no reason increase cost, the thickness of insulating barrier simultaneously
For 5.0mm.
In order to improve the impact-resistant block-water effect that improves further simultaneously, between center conductor and the first conductor, it is provided with resistance
Water yarn and waterstop.
Dismantling maintenance for convenience, insulation box body is fastened by upper cartridge body and lower box body and forms.
I is easy to inject insulating cement insulation zoarium, and upper cartridge body arranges hole for injecting glue.
As preferably, the number of hole for injecting glue is two.
As preferably, upper cartridge body is screwed with lower box body.
The invention has the beneficial effects as follows: one aspect of the present invention, it is possible to meet wanting of transmission capacity and Seawater durability
Ask；On the other hand, impact resistance is effectively raised.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the concrete structure schematic diagram of leader cable in the present invention.
Fig. 3 is upper cartridge body structural representation of the present invention.
Fig. 4 is lower box body structural representation of the present invention.
Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings:
As shown in Figures 1 to 4, a kind of Wind turbines lightning-protective cable, including leader cable 1, leader cable 1 passes through metal connecting tube
7 are provided with branch cable 8, and branch cable 8 is identical with the structure of leader cable 1；Metal connecting tube 7 is arranged in insulation box body 10；Insulation
Box body 10 is fastened by upper cartridge body 12 and lower box body 13 and forms, and in the present embodiment, upper cartridge body 12 is screwed with lower box body 13.
It is injected with insulating cement 11 in insulation box body 10；In the present embodiment, in insulation box body 10, inject insulation for convenience
Glue 11, upper cartridge body 12 arranges hole for injecting glue 14, and wherein the number of hole for injecting glue 14 is two.
Leader cable 1 includes that center conductor 2, the outside of center conductor 2 are provided with the first conductor 3, and in the present embodiment, center is led
It is provided with water blocking yarn 15 and waterstop 16 between body 2 and the first conductor 3.
First conductor 3 includes six the first conductor thread core 3a；First conductor 3 is outside equipped with the second conductor 4, the second conductor 4
Including 12 the second conductor thread core 4a；Being provided with internal shield 5 outside second conductor 4, the outside of internal shield 5 is provided with absolutely
Edge layer 6, the thickness of insulating barrier 6 is 4.8mm-5.2mm.In the present embodiment, the thickness of insulating barrier 6 is 5.0mm.
In use, the number of branch cable 8 is indefinite, and the number of branch cable 8 is according in wind turbine blade (not shown)
The flash-point that connects determine, in the present embodiment, the number of branch cable 8 is two, and two branch directions are reversed.The present invention is main
Use for multiple flash-points that connect.
Owing to branch cable 8 is connected with the flash-point that connects on wind turbine blade, therefore numbers of branches and the regularity of distribution can be according to wind
The design connecing flash-point on motor blade selects flexibly；Conductor is single group；Insulating barrier be the most of good performance absolutely
Edge material.
For improving the field uniformity of Wind turbines lightning-protective cable, improve service life, described conductor and insulating barrier it
Between extrude internal shield.For being applicable to offshore wind farm unit, described insulating barrier is Salt corrosion insulating barrier；For improving cable water preventing ability
