Product Introduction:

1. Variable Pitch wind turbine Introduce

3kw pitch controlled wind turbine adopts:  

Wind speed control blades angle changing. The blades angle twists according to the wind speed, this will change the blades itself aerodynamic characteristic to control wind turbine rotation speed. This will make the generator output power constantly. 

2. Variable Pitch wind turbine features

A.      Blades rotor: Blades rotor efficiency can reach 0.42. Noise level is less than 65db, and balance adjustment has been carried out strictly before leaving factory. 

B.       Generator: Blades rotor drives directly. Lower rotation speed, PMG synchronous generator, over load capacity is 150%. 

C.       Pitch controlled wind turbine: Adopt stable pitch controlled system, can be used in variable environments

D.      Low failure rate

E.       Speed regulates Performance: The precision of pitch controlled system is 10 r/min, and never over speed at gale. 

F.       Low Start-up Wind Speed: According to different wind conditions, adjust the blade initial angle to make wind turbine start up at low wind speed. 

G.      The start-up wind speed is ≤3m/s.

H.      Manual brake: Reliable braking system, easy to operate, can stop wind turbine at any time.  Automatically undo cable: slip rings undo the cable automatically. Ensure the cable has not twist. Double carbon brushes structure make sure power transfer without failure.

I.        Well-adapted Wind turbine: The operation wind speed is 3-30m/s.

4. Noise level. (9m height tower)

Under the tail rod, 6m/s, 50-55dba;

0-25m, wind speed 8m/s--12m/s, 35-45dba;

Distance longer than 25m, background noise is larger than wind turbine speed;
