Model: SWT-3kw pitch wind turbine
3kW pitch wind turbine is an high efficient wind power generation model, and its power output is very stable. Installation site does not need human monitoring, the system is equipped with remote monitoring system.
Variable Pitch Wind Generator
The variable pitch wind turbine generator 3kw adopts rotating speed of generator to control the angle changing of blade, as the changing of rotating speed, the blade twist the angle accordingly to change the aerodynamic characteristics of blade, controlling the rotating speed of the wind turbine generator, and changing the internal mechanism to get displacement , realizing generator constant power output. Before the turbine leave the factory, the controlling parameters of turbine pitches have been went through the strictly commissioning.
The features of wind generator:
Rotor: High-quality steel precision molding, blade is made of Reinforced Fiber Glass. High Flexural strength, high resistance to erosion and long service life.
Generator: Rotor drive directly. Low-speed permanent magnet synchronous generator, overload rate 150%
Speed adjusting performance: System control accuracy +10r/min, not overspeed when encounter gale. Rotor efficiency can reach 42%,noise level less than 65DB
Low-speed start： According to the wind condition, adjusting initial angle of blades and it can make the wind generator start at low speed , start wind speed 2mtr/s
Manual brake: Reliable manual brake institutions, it can achieve manually change the pitch and manual brake,convenient operation,shut down can be realized at any time.
Self-releasinghook: Collection ring releasinghook automatically,ensure cable without winding,double carbon brush structure to ensure power without transmission fault.
Adaptability: Application wind speed scope 3-30m/s, Convering the land common wind speeds.
