Problems solved by technology
The wind power generator mainly relies on the wind to drive the wind rotor to rotate to realize its power generation function, but once the wind speed is too high, the speed of the wind rotor will be greatly accelerated, and the operation will be unstable, resulting in damage to the blades, generator and control system, etc., resulting in wind power failure. The generator cannot be used, which limits the scope of application of wind speed; in view of the above problems, some wind generators use hydraulic electronic control speed regulation to control the speed of the wind wheel, but the structure is more complicated and it is more difficult to manufacture

Description
technical field [0001] The invention relates to a wind power generator, in particular to a pitch-variable wind rotor of the wind power generator. Background technique [0002] At present, the generators commonly used in the market mainly include diesel generators, solar generators and wind generators. The wind power generator mainly relies on the wind to drive the wind rotor to rotate to realize its power generation function, but once the wind speed is too high, the speed of the wind rotor will be greatly accelerated, and the operation will be unstable, resulting in damage to the blades, generator and control system, etc., resulting in wind power failure. The generator cannot be used, so that its scope of application for wind speed is limited; in view of the above problems, some wind generators use hydraulic electronic control speed regulation to control the speed of the wind wheel, but the structure is more complicated and the manufacture is more difficult.
