The structure of the wind turbine The <br>nacelle <br>contains the key equipment of the wind turbine, including the gearbox and the generator. 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. <br>Rotor blades <br>The rotor blades capture the wind and transfer it to the rotor shaft. On a modern 600 kilowatt wind turbine, each rotor blade measures about 20 meters in length and is designed to resemble an airplane wing. <br>The axial rotor <br>axis is attached to the low speed shaft of the wind turbine. <br>The low-speed shaft of a low-speed shaft <br>wind turbine connects the rotor shaft to the gearbox. On a modern 600 kW wind turbine, the rotor speed is fairly slow, around 19 to 30 revolutions per minute. There are conduits in the shaft for the hydraulic system to activate the operation of the aerodynamic brakes. <br>Gearbox <br>The left side of the gearbox is the low-speed shaft. It can increase the speed of the high-speed shaft to 50 times that of the low-speed shaft. <br>The high-speed shaft and its mechanical brake <br>The high-speed shaft runs at 1500 rpm and drives the generator. It is equipped with emergency mechanical brakes, which are used when the aerodynamic brakes fail, or when the wind turbine is being repaired.
