Description
Technical field
The present invention relates to a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT), especially have cost low, the brushless threephase alternator that generating efficiency is high.
Background technology
Existing high-rating generator is two pole threephase alternators at present, and it has rotor and brush, exists and affects generating efficiency because rotor weight is large.Known CN102064620B brushless AC generator and the present invention more close, it is primarily of compositions such as stator, field core, rotating cylinders, and wherein field core has two groups side by side, and the iron core and the line bag consumable material that there is stator and field core will be many, weight is also large, and cost is just high.Also have its rotating cylinder to arrange the magnetic circuit of field core in order to staggered conducting two, must have the magnetic conduction iron of two misarrangement positions, this rotating cylinder can only make 4 extremely above generators, can not make two large generators.
Summary of the invention
The deficiency have that cost is high to overcome known brushless AC generator, weight is large, can not made two pole generators, object of the present invention provides one to have cost low, the brushless threephase alternator that generating efficiency is high.
The present invention's adopted technical scheme of dealing with problems is: it comprises stator, electromagnet, rotating cylinder, switching circuit board, transducer, axle bed, base, electromagnet comprises iron core, coil, axle, rotating cylinder comprises cylinder, magnetic conduction iron, permanent magnet, end plate, gear, one group of electromagnet is provided with in stator hole, axle connects one piece of iron core, coil is contained on core magnetic pole, the semicircle magnetic pole of electromagnet is a kind of polarity, another semicircle magnetic pole is another kind of polarity, electromagnet is contained on axle bed, electromagnet pole is corresponding with magnetic pole of the stator position, a rotating cylinder is provided with between electromagnet and stator, the barrel symmetric position of the cylinder that non-magnet material is made connects a row a pair magnetic conduction iron, cylinder two end connects two pieces of end plates, gear is contained on one piece of end plate, N, S pole two block permanent magnet is contained in the symmetric position of another block end plate respectively, rotating cylinder is contained on axle, two transducers are connected in stator side plate symmetric position, transducer is corresponding with permanent magnet position, switching circuit board is contained on stator, axle bed and stator are contained on base, transducer is electrically connected with switching circuit board, DC power supply is electrically connected with coil through switch electrode plate, rotating cylinder turns half-turn and connects forward magnetic flux, turning half-turn again because of electromagnet power supply is commutated, turn-on reversal magnetic flux.When rotating cylinder half rotation, on rotating cylinder, a pair magnetic conduction iron is firm with the pole pair of electromagnet respectively, flows through forward magnetic flux, induce half sine wave at stator core; Again when rotating cylinder rotates another half-turn, because transducer is to another block permanent magnet of jail, reversing, transducer exports high level, makes reverser conducting on switching circuit board.Flow through counter magnetic flux at stator core, induce down half sine wave.Such rotating cylinder turns around and induces a sine wave alternating current.The present invention adopts a pair magnetic conduction iron on rotating cylinder, go one by one when rotated firm electromagnet and magnetic pole of the stator, go to connect and cut off magnetic circuit, play and change main flux size, adopt the mains inverter be made up of permanent magnet, transducer and switching circuit board, rotating cylinder turns around and changes secondary main flux direction, thus sends alternating current.Because rotating cylinder only has a row a pair magnetic conduction iron, electromagnet only needs one group, copper material and steel consumption few, cost is low; Two substitute heavy rotor, moment of torsion little province power because of rotating cylinder; Three do not need brush because of mains inverter, thus reach the present invention and have cost low, the object that generating efficiency is high.
The invention has the beneficial effects as follows: have cost low, generating efficiency is high, can also make two pole brushless generators, also because only having one group of electromagnet, volume is little.
