460 tonnes.
A large wind turbine weighs between 400 and 500 tonnes. The blades of a 6 MW wind turbine weigh around 70 tonnes and the generator rotor weighs around 100 tonnes. The weight of the generator stator is approximately 140 tons. Including the weight of the cabin and the weight of the tower, it is approximately 460 tonnes.
A wind turbine is an electrical device that converts wind energy into mechanical work, which causes the rotor to rotate and ultimately produces alternating current. Wind turbines generally consist of components such as a wind wheel, a generator (including devices), a steering (tail), a tower, a speed-limiting safety mechanism, and an energy storage device.
A large wind turbine weighs between 400 and 500 tonnes.
The blades of a 6 megawatt wind turbine weigh about 70 tons, the generator rotor weighs about 100 tons, and the generator stator weighs about 140 tons. Inincluding the weight of the cabin and tower, it is approximately 460 tonnes.
Due to the unstable air volume, the wind turbine produces 13-25V alternating current, which needs to be rectified by the charger, and then the battery is charged, so that the electrical energy generated by the wind turbine is converted into chemical energy.
Generator Structure:
Nacelle: The nacelle contains the key equipment of the wind turbine, including gearboxes and generators. Maintenance personnel can enter the nacelle through the wind turbine tower. The left end of the nacelle is the wind turbine rotor, that is, the rotor blades and shaft.
Rotor blades: capture the wind and transmit the wind force to the rotor shaft. On a modern 600-kilowatt wind turbine, each rotor blade is about 20 meters long and designed to resemble an airplane wing.
Axis: The rotor axis is attached to the low speed shaftof the wind turbine.
Low speed shaft: The low speed shaft of the wind turbine connects the rotor axis and the gearbox. On a modern 600 kW wind turbine, the rotor turns quite slowly, around 19 to 30 rpm. There are conduits in the shaft for the hydraulic system to activate the operation of the aerodynamic brake.
