Technical field

The utility model relates to a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT), exactly is a kind of induced variable-reluctance alternating-current generator.

Background technology

Traditional generator has the following disadvantages: first, because the conventional electric generators rotor is a magnetic pole, with stator be coil, do between the two in the relative circular motion process, the magnetic line of force is done relative cutting movement with coil, and the rotating magnetic field that the induced current of coil produces plays inhibition to rotor, and the position of the coil and magnetic line of force angle between 0 to 90 degree is big more, the resistance of the magnetic line of force is big more, and the energy of consumption is big more.This generation mode has just been finished the conversion of energy, and transformation efficiency is low, and energy consumption is bigger.The second, be easy to generate leakage field in the iron core of conventional electric generators, increase resistance, waste power also produces harmonic wave, and electrical network is had harm.

Summary of the invention

The purpose of this utility model, provided a kind of induced variable-reluctance alternating-current generator, it produces induced electromotive force by the mode that changes the size of magnetic flux in the iron core, but not pass through coil cutting magnetic line, the magnetic line of force is vertical with coil on the iron core all the time, and direction is also vertical with the magnetic line of force in relative rotation with magnet for iron core, therefore, the rotating magnetic field that induced current in the coil produces not can to iron core and magnet relatively rotate the generation inhibition, can save the required energy consumption of generating electricity; Be difficult in its iron core producing leakage field and harmonic wave, can not work the mischief electrical network, thereby, the deficiency that existing generator exists can be solved.

The purpose of this utility model is achieved through the following technical solutions: induced variable-reluctance alternating-current generator, comprise the iron core support, on the iron core support rotating shaft is installed, the two ends of rotating shaft are installed first rotating disk and second rotating disk respectively, and first iron core is installed on the iron core support, and the periphery of first iron core is installed first coil, first magnet is installed on first rotating disk, the 4th magnet is installed on second rotating disk, and first magnet is corresponding with the two ends of first iron core with the 4th magnet, and first magnet is relative with the heteropole of the 4th magnet.

For further realizing the purpose of this utility model, can also realize by the following technical solutions: second iron core and the 3rd iron core are installed on the iron core support, first iron core, second iron core and the 3rd iron core are uniformly distributed in the periphery of rotating shaft, first iron core, the center of second iron core and the 3rd iron core is concyclic, the periphery of second iron core is installed second coil, the periphery of the 3rd iron core is installed tertiary coil, second magnet is installed on first rotating disk, second magnet and first magnet equate with the spacing of rotating shaft, second magnet and first magnet be separated by 180 the degree, the 5th magnet is installed on second rotating disk, the 5th magnet and the 4th magnet equate with the spacing of rotating shaft, the 5th magnet and the 4th magnet be separated by 180 the degree, the 5th magnet is relative with the second magnet heteropole.The end surface shape of first iron core, second iron core, the 3rd iron core, first magnet, second magnet, the 4th magnet and the 5th magnet is identical with size.The pole orientation of first magnet and second magnet is opposite.

Good effect of the present utility model is: it is to produce induced electromotive force by the size that changes magnetic flux in the generator iron core in coil, and the size of generation induced current is relevant with the resistance sizes of the rate of change of magnetic flux and conductor loading.During the work of this generator, iron core and magnet relatively rotate in the process, the magnetic line of force of magnet is all the time perpendicular to the iron core end face, the direction of rotation that promptly changes magnetic flux size in the iron core becomes an angle of 90 degrees all the time with the direction of the magnet magnetic line of force all the time, with this frame mode generating, can significantly reduce the resistance that rotates between the generator stator rotor, also can improve generating efficiency simultaneously, good energy-saving effect is arranged.This Blast Furnace Top Gas Recovery Turbine Unit (TRT) does not produce leakage field in iron core, do not have harmonic wave to produce, and also can reduce a part of resistance, energy savings, and electrical network do not produced harm.
