Description

Wind power generator

This creation is about a wind kinetic energy conversion unit, especially a wind power generation device that can resist the damage of instant strong wind.

The conventional wind power generation device relies on the natural wind to push the fan blades and make the fan blades turn to work for the generator. It can convert wind energy into electrical energy for convenient storage or transmission of energy, which is used to meet the energy needs in life. However, the strength of the wind in nature is unstable and uncontrollable. When the wind is weak enough to push the blade, the generator stops outputting electricity; when the wind is strengthened to exceed the structural strength of the blade or the load of the generator, it may cause the blade Problems such as reduced life or overheating damage to the generator circuit.

The conventional wind power generation device overcomes the problem of unstable wind by adding a gearbox. The gearbox can increase the rotation speed when the wind kinetic energy is insufficient, to avoid the generator from stopping, and reduce the generator efficiency when the kinetic energy increases, to avoid Motor overload. However, the conversion and transmission of energy through the gearbox results in additional energy consumption. In addition, the gearbox can only protect the generator, and cannot reduce the instantaneous wind pressure on the fan blades.
