A generator set suitable for both low-speed and high-speed wind

Abstract

The purpose of the present invention is to provide a kind of generating set applicable to both low-speed and high-speed wind power, including wind turbine, clutch, low-speed permanent magnet wind generator, high-speed permanent magnet wind generator; clutch includes hollow gear, solid gear, hollow gear shaft, the upper and lower ends of the hollow gear shaft are respectively installed with the first steel plate and the second steel plate, the outer side of the first steel plate is installed with the first electromagnet, the first spring, and the first armature in sequence, and the inner side of the first steel plate is installed with the second electromagnet in sequence , the second spring, the second armature, the inner and outer sides of the second steel plate have the same structure as the first steel plate, the inner wall of the hollow gear is located outside the first armature and the third armature, and the solid gear is arranged below the hollow gear; the wind turbine is connected to the hollow gear The shaft of the low-speed permanent magnet wind generator is installed between the second armature and the fourth armature, and the shaft of the high-speed permanent magnet wind generator is installed in the solid gear. The invention can complete normal operation under low wind speed and high wind speed.

Description

technical field [0001] The invention relates to a power generating device, specifically a wind power generating device. Background technique [0002] Wind turbines are in a natural environment, and the wind speed changes frequently and in a large range. The wind turbines currently in operation are equipped with a cut-out wind speed, that is, the wind turbines that exceed this wind speed will be cut off from the power grid, and the control system will take normal shutdown for protection. Otherwise, it will often It will cause the generator to overspeed, overheat and cause failure. In order to ensure the long-term normal operation of the wind turbine, overspeed and overheating protection devices must be installed on the wind turbine. But at present, the existing wind turbine overspeed protection generally adopts multiple instantaneous electric short-circuit braking devices. However, in the state of strong wind, high speed of wind rotor and large rotational torque, sudden inst...
