Protection system of wind generator against mechanical damage and overloading caused by the exaggerate wind speed

摘要

The object of the invention is a system to protect the wind generator, especially small and medium power, against mechanical damage and overload caused by excessive wind speed, both on land-wide open surfaces and in coastal zones of large water tanks. The system consists of a wind generator (1),which contains a beam (2) and three double propellers (3),of the support structure (4) of the generator, with current (5),control wing (6),Jarm (7) of the protective system, rotary axis (8) of the protective system, mass (9) of the wind generator and one release spring (10). One end of the towing spring (10) is fixed to the mass (9),above the axis of rotation (8) of the harness of the protective system and the other end of the towing spring (10) shall be fitted to the harness (7) of the protective system. Jarzmo (7) has a foot (11),Pressing the yoke (7) connected to the generator (1) to the mass (9) in the working position and pressing the yoke (7) connected to the generator (1) to the mass (9) in the maximum deviation position, as a total protection position. Distance "a" between the lower end of the lower propeller (3),and the axis of rotation (8) of the spring is less than the distance "b" between the top end of the upper propeller (3),and the axis of rotation (8) of the yoke, both in the working position and in the position of total protection.
