Description
Technical Field
The invention relates to the technical field of temperature control of wind driven generators, in particular to a multifunctional temperature control heating system.
Background
Wind power generation is one of the more readily available clean energy sources that can convert wind energy into electrical energy. When the wind wheel rotates, the wind wheel rotates under the action of wind force, the kinetic energy of the wind is converted into mechanical energy of a wind wheel shaft, and the wind wheel shaft drives the generator to rotate through the gear transmission structure to generate electricity after rotating. In order to reduce the influence of the surrounding environment on wind power, wind power generators are usually arranged in open fields, buildings in the surrounding environment are few, the generators are still at high altitude, and the wind cannot be weakened due to the influence of the buildings. In this way, in cold weather, the temperature of the nacelle begins to decrease, the temperature of the generator located inside the nacelle also decreases, and once the temperature of the generator decreases, the frost or dew formation phenomenon may easily occur inside the generator, which may affect the electrical insulation performance of the generator.
Furthermore, in the power generation process of the generator, the rotation of the wind wheel shaft drives the rotor shaft of the generator to rotate through the gear transmission structure, the permanent magnet on the rotor shaft rotates along with the rotor shaft, the coil on the stator generates current when the permanent magnet rotates, the rotor is positioned in a current magnetic field generated by the stator coil, and heat loss exists in the rotation process, so that the permanent magnet generates heat. In order to dissipate heat, in the existing wind driven generator, air is blown into the generator to take away heat in the generator, so that the temperature of the permanent magnet is reduced, and loss of the permanent magnet caused by high-temperature demagnetization is reduced.
Therefore, in order to ensure the normal use of the permanent magnet, effective heat dissipation of the generator is also required. In order to improve the heat dissipation effect of the conventional generator, chinese patent No. CN102447327A, issued to siemens corporation, discloses a generator in which heat of a permanent magnet is conducted out by a heat sink provided on the outer side of a rotor yoke, thereby improving the cooling effect of the permanent magnet. In view of the above patent, the inventor of the present application believes that, because the wind power generator converts wind energy into electric energy, when the wind speed is high, the rotating speed of the wind wheel is increased under the action of wind force, the rotating speed of the rotor shaft of the generator is increased, the rotating speed of the permanent magnet is increased, the current generated on the coil is increased, and after the current is increased, the magnetic field strength around the current is increased, so that the heat loss on the rotor in the magnetic field is increased, the temperature of the permanent magnet is increased, and the probability of demagnetization of the permanent magnet due to high temperature is increased. However, since the natural phenomenon of wind is not artificially controllable, and most wind power generators are arranged in open areas, and no shelter is arranged around the wind power generators to reduce the wind power, the phenomenon of high rotation speed of the rotor shaft of the generator caused by high wind power cannot be eliminated, and therefore, a new solution is required to reduce the possibility of high temperature of the permanent magnet caused by high wind speed.
