Strong breeze resisting minitype wind driven generator

Abstract

The invention provides a strong breeze resisting minitype wind driven generator which comprises a generator main shaft, a blade, a shell, a generator rotor and a generator stator, wherein the blade is fixed on the generator main shaft; the shell supports the generator main shaft through a bearing; the shell comprises a stator shell, a front end cover which is positioned at the front end of the stator shell and a rear end cover which is positioned at the rear end of the stator shell; the generator rotor is positioned in the shell and fixed on the generator main shaft; the generator stator is fixed on the inner surface of the stator shell of the shell, corresponding to the generator rotor. The wind driven generator is characterized by also comprising a controller and a mechanical electromagnetic brake which are connected, wherein the mechanical electromagnetic brake is installed on the generator main shaft; and the controller is used for controlling the mechanical electromagnetic brake to brake. The strong breeze resisting minitype wind driven generator provided by the invention can not be forced to rotate by strong breeze, thus the safety of the minitype wind driven generator is ensured.

Description

technical field [0001] The invention relates to a small wind power generator, in particular to a strong wind resistant small wind power generator. Background technique [0002] As a natural resource with abundant reserves, wind energy has been widely used and developed rapidly all over the world due to its convenient use, renewable, low cost, and non-polluting characteristics. huge. In recent years, the market of small wind turbines has also developed very rapidly, and the application areas are becoming wider and wider. However, as the global climate warms, extreme climates continue to appear. Taking China as an example, sandstorms in the north occur more frequently and more intensely every year; the probability of super typhoons above 16 in the south is increasing higher. All these realities have put forward higher requirements for the safety of small wind turbines. At present, small wind turbines below 5 kW at home and abroad basically use mechanical yaw, generator sho...

AI Technical Summary

Problems solved by technology

At present, small wind turbines below 5 kilowatts at home and abroad basically adopt the main braking methods such as mechanical leading yaw, generator short circuit (generating electromagnetic braking force) and unloader, but all these traditional safety braking methods , cannot safely withstand severe weather like a super typhoon
