After the wind power generator is installed, it is always in the severe test of nature. In addition to being attacked by wind, frost, rain, and snow, it may be attacked by lightning, hail and wind sand. The working environment of wind turbines is very bad, so the correct use and maintenance of wind turbines […]
Small wind turbines are suitable for areas where the annual average wind speed is above 3m/s, and the cumulative annual effective wind speed of 3~20m/s is above 3000h: the annual average effective wind energy density of 3-20m/s is above 100W/㎡. Small horizontal axis wind turbines generally consist of the following parts: wind wheel, generator, rotating […]
① Output characteristics of wind turbineThe torque produced by a horizontal-axis wind wheel with a fixed pitch varies with wind speed and rotation speed. If the rotation speed of the blade is too low, the blade will stall and the torque output by the wind wheel will decrease. Therefore, in order to obtain the maximum […]
A wind turbine whose installation position of the wind wheel axis and the horizontal plane is not greater than 15° is called a horizontal axis wind turbine. The wind wheel of a horizontal axis wind turbine rotates around a horizontal axis. The blades are arranged radially, perpendicular to the axis of rotation, and at an […]
