Problems solved by technology
Wind generators are necessary equipment for wind power generation. However, the protection performance of existing wind generators is poor. When the wind is too strong, the blades will rotate faster, which will easily cause the power generation to exceed the set value and cause the circuit to burn out, and the generator and The gear box generates heat due to shaft rotation, which leads to an increase in the internal temperature of the wind turbine casing and the temperature of the gearbox oil, which affects the service life

The invention belongs to the technical field of wind power generation and particularly relates to a wind power generator with a speed-limiting protective switch. To solve the problem that when wind istoo big, blade rotating speed is too high, and burnout of circuitry due to power generation exceeding a set value is easily caused, the wind power generator with the speed-limiting protective switchis disclosed. The wind power generator comprises a housing; a tower vertically arranged is welded to the middle of the bottom outer wall of the housing; a circulation water pump is fixed to the outertop end of one side of the housing via screws; a support plate horizontally arranged is welded to the middle of the outer wall of one side of the housing. an anemometer provided herein can detect windspeed around the housing; when the wind speed exceeds the set value, a hydraulic cylinder is started under control of a controller; a rubber pad approaches and contacts and rubs the outer wall of a steel ring; under the action of frictional force, rotation of a wind wheel shaft is reduced, and rotation of a generator shaft can be decreased via a gearbox, power generation quantity is limited, burnout of circuitry due to too high power generation quantity is avoided, and good protection is provided.
Description
technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind power generator with a speed limiting protection switch. Background technique [0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind is a pollution-free energy source. The use of wind power generation is very environmentally friendly and can generate huge electric energy. Therefore, more and more countries pay more attention to wind power generation. As a As a clean and renewable energy, more and more countries in the world pay attention to it. Its reserves are huge. The global wind energy is about 2.74×10^9MW, of which the usable wind energy is 2×10^7MW, which is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. Wind has long been People use - mainly to pump water, grind flour, etc. through windmills, and now, people are interested in how to use wind to...
