Its length varies from 40 to 90 meters.
Generally speaking, the length of wind turbine fan blades is between 40 meters and 90 meters. For example, the blade length of a 1.5 MW wind turbine is approximately 40 to 55 meters, the blade length of a 2 to 3 MW wind turbine is approximately 55 to 65 meters, and the length of the blades of a wind turbine of 5 MW and more is between 65 and 65 meters. and 90 meters.
Wind turbine fan blades are made of carbon fiber, glass fiber and other materials, light in weight and high in strength. Its working principle is to use wind energy to turn a generator and convert wind energy into electrical energy. Wind energy is not only clean and environmentally friendly, but also reduces dependence on traditional energy sources, which is of great importance for sustainable development.
A big starwind 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. Including 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.
Detailed information:
Invented almost simultaneously by China, Japan and Europe in the beginning of the 21st century A new type of wind turbine, different from the first vertical axis wind turbine (Darieu type), it is more efficient than the horizontal axis wind turbine, has no noise or steering mechanism and is simple to maintain.
It has become the first choice for wind turbinessmall and medium sized in European and American markets. The world's current highest power is the 50 kW vertical axis wind turbine produced by Shanghai Mushi Electronic Equipment Co., Ltd. (MUCE). The maximum power in Japan is 30 kW.
