1. The main shapes of wind turbine blades are 126/110/114, etc., and the corresponding blade sizes are 68m, 54m, 56m. Now the diameter of the largest wind turbine blade has exceeded 70 meters; , which is equivalent to the wingspan of a Boeing plane.
2. Blades are an industry with high certainty, large market capacity and a clear profit model among wind power components. As the tense supply and demand situation eases, the wind power blade industry will also undergo a transformation, from a melee between a group of heroes to a struggle for hegemony between some powerful actors. redesign and integration.
3. As the wind turbine blade market expands, costs and sales prices will decrease. However, companies with scale, technology and cost advantages will see their costs fall faster than their prices.th sale. their profits will exceed the average level. The future competitive landscape of the industry requires manufacturers to expand their scale, reduce costs and maintain certain technological advantages.
The conductor is usually a coil of copper wire. In the generator, the rotating shaft is connected to a permanent magnet wrapped in the coil. In the process of electromagnetic induction, if there is a magnet around a conductor, then when the relative rotation between the magnet and the conductor occurs, a voltage will be induced in the conductor. When the rotor turns the shaft, the magnetic component is rotated by the shaft, creating voltage in the coil. The voltage causes current to flow through the wires for power distribution, and the resulting current is usually alternating current.
For example, a wind turbine consists of three blades, each blade is 77 meters long. She likence to produce electricity when the wind speed reaches 3 meters/second. The fan blades can rotate 20 times per minute and one revolution covers an area of 4,600 square meters. When the wind speed reaches 15-25 meters/second, the fan is under full load and can generate 1,500 kilowatts of electricity per hour, which means 1,500 1,000 watt electric kettles can be plugged in at the same time to to boil the water. Of course, not all winds can be used for wind power generation, such as typhoons and hurricanes that we often encounter in summer and autumn. Although wind power is huge, it is inefficient and cannot be used for wind power generation.
