Automatic adjustment of 1800 watts DC does not require a regulator and costs more than 100 yuan. If your car does not have an electric starting device, use a 1,500-watt AC generator. The price is around 70-80. Agricultural machinery accessories are available, but I suggest you use the first self-adjusting DC generator, because this type of generator is available. The generator automatically stabilizes the voltage and does not burn out the bulb. I'm a repairman, trust me!
The concept of the number of wind turbine blades - the strength of the wind turbine. The ratio between the total surface area of the wind turbine blades (projected in the direction of the wind) and the surface area where the wind passes through the rotor (swept rotor surface) is called solidity (or solidity ratio, volume ratio), and constitutes a reference data for wind turbines. ?
These are several types of horizontal axis wind turbines, with diagramss schematics showing four types of wind turbines: single blade, double blade, three blade and multi blade. The method of calculating solidity. of the wind turbine is as follows: S is each the projected surface of the blades in the direction of the wind, R is the radius of the wind wheel, B is the number of blades and σ is the realism ratio. σ=BS/πR2 ?
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. Generally speaking, wind energy is also solar energy, so we can also say that a wind turbine is a thermal energy generator that uses the sun as a heat source and the atmosphere as a heat fluid. work.
