Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Embodiment
Referring to Fig. 1, the utility model provides a kind of technical scheme：A kind of permanent magnet synchronous wind generator lightning protection device,
Including arrester 13, the arrester 13 is connected with blade downlead 1 and blade 2, and the blade downlead 1 is connected with drainage and turned
Contact pin 6, the drainage switching piece 6 is connected with second electrode 8, and the blade 2 is connected with kuppe 3 and wheel hub 4, the wheel hub 4
Connect provided with electromagnetic shielding net 5 and first electrode 7 in the shell of generator amature, the electromagnetic shielding net 5 is connected with cabin 10,
The cabin 10 is provided with pylon 12, and the first electrode 7 is connected with insulating barrier 11 and motor downlead 9, under the motor draws
Line 9 is connected with earth cable 15, and the earth cable 15 is provided with deconcentrator 14, and the arrester 13 uses metallic conduction material
Material, and needle-shaped tip structure is used, blade downlead 1 and motor downlead 9 surface scribbles insulated paint, and the wheel hub 4 is adopted
With composite insulating material, the electromagnetic shielding net 5 uses metal material, network structure, the first electrode 7 and second electrode 8
It is cylindric, the first electrode 7 is arranged on the inner surface of wheel hub 4, the second electrode 8 is nested on motor bearings.
Operation principle of the present utility model：Under thunder and lightning environment, thunder is attracted by the arrester 13 installed in the top of blade 2
Electricity, so as to ensure that thunder and lightning does not hit cabin 10 directly, or other generator components cause to damage, while blade downlead 1 is by thunder
