Description
Technical field
The utility model relates to a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT), particularly relates to a kind of constant DC electric generator.
Background technology
At present, widely used generator is alternating current generator substantially, and some so-called DC generator are all rely on alternating current generator to adopt commutator to obtain direct current to export, and Constant Direct Current then also just can obtain with circuit rectifies.Brush in commutator repeatedly rubs in generator operation, easily damages, and can produce heat when conduct electrical power, and the mechanical energy reducing generator becomes the transformation efficiency of effective electric energy.Now, though there are some there is no the design of the DC generator of commutator, but they all well solve the problem that many group coils connected in series generation high voltages export, all by increasing magnetic field intensity, rotating speed or this three of cutting zone conductor size increases induced electromotive force, but when these variables cannot increase by external condition restriction, induced electromotive force also just can not add again.In existing DC motor structure, although there is the conductor of multiple cutting magnetic field, they are all parallel relationship, and the voltage source of parallel connection can not superimposed voltage, and the induced electromotive force finally obtained is the same with the size that single conductor produces.
Utility model content
It is simple, cheap for manufacturing cost that technical problem to be solved in the utility model is to provide a kind of structure, do not need commutator and circuit rectifies just directly can export Constant Direct Current, and the series connection of multiple cutting magnetic field conductor can be realized, complete the overlapped in series of voltage source, when magnetic field intensity, rotating speed, cut lengths are invariable, larger induced electromotive force and the constant DC electric generator of output voltage can be obtained.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of constant DC electric generator, comprise symmetrical cylindrical magnet, and the coil brace be arranged between symmetrical cylindrical magnet, symmetrical arc mounting structure is provided with in described coil brace, described symmetrical arc mounting structure coordinates with concentric wheel shaft to install and realizes the not exclusively fixing of coil brace, and described concentric wheel shaft two ends are fixedly connected with symmetrical cylindrical magnet respectively.
On the basis of technique scheme, the utility model can also do following improvement.
Further, described cylindrical magnet is permanent magnet material, and under difficult environmental conditions, permeability change is less, therefore can produce constant magnetic field intensity for described permanent magnet material, finally realizes constant direct current and exports.
Further, described coil brace is provided with multiple symmetrical arc connected in star, each symmetrical arc connected in star is provided with coil windings, described coil windings in fall 8-shaped be looped around on symmetrical arc connected in star, be connected in parallel between described coil windings, for realizing conductor perpendicular cuts magnetic induction line to produce induced electromotive force.
Described symmetrical arc connected in star inwall is provided with the extremely low material coating of permeability, for changing the direction of transfer of magnetic induction line.When magnetic induction line is passed to coil brace, because symmetrical arc connected in star inwall permeability is low, magnetic induction line is walked around symmetrical arc connected in star and is transmitted, and makes magnetic induction line density outside coil brace much larger than the magnetic induction line density in symmetrical arc connected in star, is conducive to obtaining larger induced electromotive force.
Further, described coil brace is made up of the material that permeability is high, and the high material of described permeability has higher permeability, is conducive to the transmission of magnetic induction line, improves induced electromotive force, thus improves the machinery of constant DC electric generator and the conversion efficiency of electric energy.
Further, described concentric wheel shaft is that the high-abrasive material that permeability is extremely low is made, and for preventing magnetic induction line from transmitting from concentric wheel shaft, producing the induced electromotive force of different directions, reducing total induced electromotive force, thus the direct current reducing constant DC electric generator exports.
Utility model works principle is as follows: when symmetrical cylindrical magnet rotates, produce the motion of perpendicular cuts magnetic induction line, the induced electromotive force that described motion is maximum under can making coil produces situation at that time, the electromotive force that described each solid conductor produces is a voltage unit, is designated as V
raw, the electromotive force direction produced due to each solid conductor is different, and forward is designated as V
raw +, be oppositely designated as V
