Technical field
The present invention relates to technical field of generators, more specifically say the frequency conversion generator that adopts permanent magnet, be applicable to firepower wind-force or hydroelectric power generation.
Background technology
The conventional electric generators of using both at home and abroad at present is that synchronous generator is taken as the leading factor.This synchronous generator, exist larger Energy Consumption Factors in internal structure, have influence on the discharge capacity of the coal consumption of heat power factory and carbon dioxide, mainly be the manufacture craft of this synchronous generator, always all strictly following rotor and the static motor stator that does not rotate of the rotating part of generator, the number of pole-pairs of the electromagnetic field that its coil winding becomes, the frequency dimension of the output electric energy that both are consistent in must the maintenance machine just can play synchronous operation the time is held in 50 He Zhi or the external frequency 60 He Zhi scopes of domestic electrical network and obtains the fully loaded generating capacity, if and normally supply out production to electricity consumer. life electric energy. run counter to this rule, then form the asynchronous of generator, the power output of motor can't normal power supply.Tracing it to its cause mainly is that the rotating speed of synchronous generator calculates designing program, and must meet consistent formula of generally acknowledging both at home and abroad; Rotation speed n=(120 * frequency f) ÷ number of poles p (rev/min), therefore in the ordinary course of things, the rated speed of synchronous generator is 3000 rev/mins when motor is a pair of magnetic pole, and synchronous speed is 1500 rev/mins during two pairs of utmost points, three pairs of utmost points need 1000 rev/mins, four pairs of utmost points are wanted 750 rev/mins ... etc. rule, so it seems accordingly this class motor, its rotating speed is lower, the magnetic pole logarithm is more, volume will be larger, and weight is more, and manufacturing cost is higher.But the manufacturer that has formed synchronous generator since consistent all follows this rule and prepares, and can't change.
The general performance condition of synchronous generator in view of the above in the go back to nature enforcement of regenerative resource of current energy-saving and emission-reduction, in reply new situations development trend, seems that really some is inadaptable, and backward sensation has been arranged.If because will use the nature minimizing to the wind-force of the pollution resource of gas. waterpower is used for generating. power supply, these renewable energy resources are come in the Nature, exist utmost point factors of instability reason, real difficulty is kept constant high rated speed, if will can produce frictional resistance again and increase manufacturing cost and the transfer power that reduces electric energy with gear graduation, if take into account both, the transformation of synchronous generator is innovated very urgent.
How could allow electric generator energy-conserving reduce discharging, a lot of people are studied this problem, open source literature also has some reports, for example: Chinese patent:＜application number〉200820065818＜notification number〉201167273＜denomination of invention〉the common armature asynchronous electric permanent magnetic frequency increase power machine,＜applicant〉Taihao Science and Technology Co., Ltd, Taihao Building, Gaoxin Road, High-Tech Development Zone, Nanchang, Jiangxi Province＜postcode〉330029＜inventor〉Lin Zhengan,＜summary〉a kind of common armature asynchronous electric permanent magnetic frequency increase power machine, the bottom of stator slot arranges the power frequency motor winding in stator core, the upper part of stator slot arranges the intermediate frequency generator winding, at rotor core the power frequency motor dboule squirrel-cage winding is set, the rotor top of rotor core arranges permanent magnet, the rotor core two ends are copper coin, damper rod and conductive copper bar are welded on the copper coin of two ends, damper rod penetrates in the damping hole of punching, the trench bottom that the conductive copper bar places punching to form, permanent magnet places groove top, fixed by the slot wedge wedging, support is passed through in punching, fixed lever and two end plates are fixed on the machine shaft with the rotating shaft location.Its technique effect is: power frequency asynchronous motor and permanent magnetism intermediate frequency generator share a stator core and rotor core, make the axial length of motor short, save the confined space, are applicable to variable-frequency power generation.
Another Chinese patent:＜application number〉200610106593＜publication number〉101106294＜denomination of invention〉high-speed self started frequency conversion generator＜applicant〉Wan Dehong, ten thousand red＜contact addresses〉the new small stream bridge in the Nanchang City, Jiangxi Province 4 districts No. 8＜postcode in 40 the 2nd buildings〉330024＜inventor〉Wan Dehong, ten thousand red＜summaries〉a kind of high-speed self started frequency conversion generator, consisted of by the concentrated winding 2 on external stator core 1, the stator tooth, rotor core 3 and deep embeded type rare-earth permanent magnet 4.For realizing self-starting function, at the adjacent notch of motor stator, place three Hall element IC, make this generator may operate in motor self-starting operating mode.Two kinds of structures are arranged, i.e. 12 grooves, 8 utmost points and 6 grooves, 4 utmost points.The buried purpose that enters in the rotor core of permanent magnet, can obtain the permanent magnet generator (more than the 10000r/min) of high rotating speed safe handling.For making generator be output as sinusoidal wave electromotive force, air gap between rotor core and stator core should keep the close distribution of sine magnetic.This motor and the coaxial installation of high-speed fuel oil engine, when the control engine rotation speed change, the output of generator can obtain three-phase alternating current V/F variable frequency power supply, for making engine start, utilize the Hall signal in the generator, make motor against operating in motor working condition, reach the self-starting purpose.Be applicable on hybrid power HVE automobile or the motorcycle.

Summary of the invention
Purpose of the present invention provides and a kind ofly can overcome the deficiencies in the prior art part, can adjust generator speed, has alleviated volume, and the frictional resistance during operation is little, frequency conversion firepower, wind-force or the hydroelectric generator of the permanent magnet that efficient is high.
The present invention adopts converter technique and magnetic pole two like magnetic poles repel each other, there is a natural attraction between the sexes and produce magnetic suspension and magnetic recommend principle of dynamics in conjunction with and be prepared into generator.Concrete summary of the invention is:
Permanent magnet frequency conversion generator of the present invention comprises shell, main shaft, bearing and coil, be characterized in: enclosure is pasted with permanent magnet blocks, main shaft is hollow structure, be fixed on the bearing, some groups of coils are on main shaft, wire is drawn in the main shaft of hollow, that is to say, main shaft does not rotate, by wind-force, waterpower, firepower or other power shell is driven around the main shaft rotation, coil in the process of permanent magnet rotation cutting magnetic line and send voltage, electric current outputs to power consumption equipment or stores electrical equipment from the wire in the middle of the main shaft.
Described enclosure is by being pasted with permanent magnet blocks and the plate shaped device that becomes full magnetic suspension and magnetic to recommend combination being installed.
The device that above-described full magnetic suspension and magnetic are recommended combination is that a side is equipped with the dull and stereotyped A that an iron or steel processing obtain in the enclosure, the permanent magnet blocks that the upper surface of dull and stereotyped A is being pasted monolithic S-N magnetic checker, evenly be covered with whole dull and stereotyped A upper surface, dull and stereotyped A permanent magnet blocks that lower surface is pasted is to be one group by two same polarities, with adjacent two Magnetic Phases another group of permanent magnet together, group with organize between the opposite checker of polarity, evenly be covered with whole dull and stereotyped A lower surface, the number of the S.N of its permanent magnet equates; The below of dull and stereotyped A is symmetrical arranged the dull and stereotyped B of an equal volume too, and dull and stereotyped B and main shaft are fixed into one, and the upper surface of dull and stereotyped B is also pasted the permanent magnet blocks of full S-N magnetic checker; The upper surface permanent magnet blocks of A, two flat boards of B is opposite with the permanent magnet blocks magnetic pole (S-N) of enclosure, and when external force drove the shell rotation, dull and stereotyped A rotated synchronously, can send induced potential, electric current and be in two kinds of coil windings between magnetic pole.Dull and stereotyped B (8) that main shaft do not rotate produces magnetic suspension in opposite directions and magnetic is recommended effect because dull and stereotyped A (7) rotates and is fixed in shell.
Above-described permanent magnet blocks is to contain the permanent magnet that the compound of rare earth lanthanide composition and iron, boron consists of.
Permanent magnet frequency conversion generator of the present invention is applicable to firepower, wind-force, morning and evening tides or hydroelectric power generation.
The principle of magnetic suspension of the present invention and magnetic push-pull arrangement is as follows:
As dull and stereotyped A, when dull and stereotyped B magnetic sheet is in static state, magnet magnetic is owing to the repulsion of the same sex exists the suspension situation, stator and rotor-position change occur if motor drives in external force, the magnetic pole of two groups of magnetic sheets will change, if the rotor of meeting repulsion motor was tangentially advanced forward and is arrived the heteropole interval when polarity of magnetic circuit was identical relatively, the suction drafting ability of opposite pole also can make rotor continue to move ahead, and goes round and begins again, and generator can constantly turn round under external force drives and power.Permanent magnet be installed in relatively to two iron plates form the up and down fully permanent magnet suspension state of the same sex, can make motor do running without frictional resistance, can realize that little external force driving also can quota decide Power operation.
In this generator, the stator winding coil of synchronous generator and the magnetic circuit number of pole-pairs between rotor have been changed with permanent magnet, the anglec of rotation of motor is morphed, the speed of service of generator is minimized and keeps quota to decide power stage electric energy And and form suspending power by the magnetic repulsive force that produces between the permanent magnet in generator frame, frictional resistance when having reduced operation, also so that the active force of mutually recommending of magnetic force helps generator to reduce driving power consumption when operation, realize that the electric weight that little outer power-actuated slow-speed of revolution can both send rated power is independently-powered.
The magnetic pole that contains the permanent magnet that rare earth lanthanide and iron boron compound be combined into, have " two like magnetic poles repel each other. there is a natural attraction between the sexes " characteristic.If find expression in two permanent magnets when being both S or being all the N polarity chron, its meet will produce each other because of repulsive force between the two artificially firmly to push away near both but can reserve eventually the certain intervals distance and can not make them receive a place, Here it is, and both repulsion makes so, if and when both respectively be S or N polarity chron respectively, then when both namely can be integrated the other side's drawing behind the certain distance, Here it is magnetic drafting ability.
Abroad take the lead in the repulsive force principle of magnetic pole is used at the high ferro train, made the frictional resistance when magnetic suspension overcomes train operation, thereby the repulsive force of energy-conservation again high speed, safety, magnetic force is permanent magnet at all and tries hard to keep the minimum static balancing of magnetic energy of magnetic, allow in the magnetic field magnetic flux quantity the most sufficient, be tending towards again the minimum basic situation of loss of excitation, the relative repulsion existence by magnetic force in the magnetic circuit has just produced fully permanent magnet suspension naturally.Object can movement will be eliminated frictional resistance on magnetic suspension force, naturally also removed large driving force from, reaches energy-saving run.This project has been added one group of permanent magnet that can change with the movable alternately S.N of rotor operation at generator, corresponding at the fixing permanent magnet S .N magnetic pole that does not participate in the moving variation magnetic circuit device that alternates again, make generator acquire fully permanent magnet suspension and along the non-resistance operation of garden week.
Frequency conversion generator rotational shell of the present invention is for so that the permanent magnet that is assigned on the body gives full play of the thrust of magnetic pole and the specific function of drafting ability, this frequency conversion generator is equipped with permanent magnetism and is arranging and need arrange especially, when its crux is moving and quiet stickup, an assembly wherein is to paste magnetic by single S-N magnetic pole checker, it is different to form adjacent magnetic pole, one group of corresponding magnetic circuit then is to link to each other with two sheets that alternately to become magnetic pole adjacent again, two is homopolarity (for example S utmost point), then apart replace two of next side should become the N utmost point, so just can obtain moving section and the quiet part magnetic suspension force of two groups of permanent magnets, will obtain again in addition to drive the little displacement of rotor in faint external force has magnetic thrust constantly to move forward with drafting ability, the magnetic suspension of Here it is frequency conversion generator of the present invention, magnetic force is recommended the whereabouts of action principle.
For the unsteadiness factor to the energy that derives from the Nature of capturing that synchronous generator exists, normally send electric energy thereby have influence on, also can keep stable voltage for making generator reach the slow-speed of revolution, the rated power of electric current and flow to electricity consumer and normally use this difficult point, through studying for a long period of time and putting into practice, the inventor is engaged in the motor design for many years originally, produce and carry out for a long time concentrating on studies by dark one deck again on the experience accumulation basis of maintenance practice of radio set and putting into practice, concentrated decidedly frequency conversion. magnetic suspension, magnetic force push-pull technique principle organically is incorporated on the same body of generator and uses.Constantly adjustment in R﹠D process. consolidate, substantial innovation obtains significantly to generate electricity effect to improving eventually, has obtained success!
The present invention owing to used converter technique and magnetic pole two like magnetic poles repel each other, there is a natural attraction between the sexes produces and recommend principle of dynamics combination and be prepared into generator.Specifically in generator, changed the stator winding coil of synchronous generator and the magnetic pole logarithm between rotor morphs the anglec of rotation of motor with permanent magnet, the speed of service of generator is reduced and keeps at full capacity power stage, and the magnetic repulsive force formation suspending power by between the permanent magnet of generator frame, producing, frictional resistance when having reduced operation, also so that the active force of mutually recommending of magnetic force helps generator to reduce driving power consumption when operation, realize that little outer power-actuated slow-speed of revolution can both send rated power output face independence normal supply electric energy.
Generator application of the present invention is more convenient for the universal direct driving of Feng Li Vortex wheel fan blade in wind-driven generator.It can make the change of electric energy frequency the change forelock motor of this type, is that the outer rotation case of generator must not be formed by stacking with the silicon steel sheet jet-bedding again, and the copper insulated conductor that does not also re-use expensive cost turns to coil groups and rolls off the production line in the punching groove.Make it that the excitation by dc low-voltage generates an electromagnetic field in generator.
China's economic is contributed to global GDP and is taken up an area ball 8%, but to consume the iron and steel of the whole world 45.6% coal and 40% and 40% cement, therefore become the maximum discharging of global carbon dioxide state, implement in the whole world for reply " the United Nations's climate changes framework convention " energy-saving and emission-reduction, shoulders heavy responsibilities." the United Nations climate change framework convention " relevant leader once pointed out: " there is the natural resources that can reduce in a large number the dusty gas discharging in the whole world, but faces outmoded, out-of-date energy technology " risk of stagnation ... ".This is showing that the excavation of new technology of the present invention has potentiality more wide, more deep layer to hold research and development.
Compared with prior art, the substantive distinguishing features of the structure of generator of the present invention and significant progress are:
The present invention has changed the stator that changes to of traditional mid-generator rotor, because when traditional generator carries out the tangent line rotation, it will inevitably could be passed to the electric energy that produces in the electrical network through the connection relationship of carbon scrape along slip ring in generator operation just can send to electricity consumer, be difficult to like this power drive of the universal wind energy resource of occurring in nature all-weather, because the wind-force of four corners of the world direction, make motor tired in break-in continually should from, make sometimes the wire damage and dangerous.On the other hand, the wearing and tearing that electricity is wiped, powdered carbon pollute for Yong Tu Time in high pole street lamp illumination etc., are difficult to safeguard.It is fixing that the present invention has changed being changed into by mid-type motor rotating parts of traditional synchronous generator, do not remake to drive running.
Rotating part of the present invention is the shell body of motor, is more convenient for so the direct driving of the universal fan blade of wind turbine or waterpower.It can make the change of electric energy frequency this type frequency conversion generator, the shell that is the outer rotation of generator must not be overrided to form with the silicon steel sheet jet-bedding again, also need not expensive insulated copper wire scratch and make among the jet-bedding of nuzzling under the coil groups, make it to motivate electromagnetic field by increasing the dc low-voltage electric current with generation in generator, now change into the soft iron wooden handcart make be spaced in intervals with generator unit stator after, in the internal diameter of the plane of this ironware, directly paste and contain rare earth lanthanide composition and iron, the permanent magnet that the compound of boron consists of substitutes the excitatory magnetic pole winding of the motor And that the insulated copper wire turns to and is alternately to be separated by with the S.N monolithic to arrange and average the stickup garden week (sheet of certain S.N of attention is counted equal amount during stickup) in full this rotor thick and fast, and such rotor can be set as the many number of magnetic poles of several times and greater than the magnetic pole of the stator magnetic circuit of copper conductor coiling.Know therefrom, the rotor that is made of permanent magnet is whenever it moves a slice magnetic position, stator winding coil will obtain cutting one group of magnetic line of force and can produce induced potential and electric current, because the uniform number of magnetic poles of rotating part is significantly more than stator, like this whenever rotate one garden week radian then the electric energy frequency direct ratio numerical value will occur has increased, the electric energy output frequency of generator will change.So if frequency conversion generator is kept the transmission of electricity rated frequency power supply of 50 cycles, no longer demand is so high fast naturally for the rotating speed of driving generator, and this can overcome the necessary condition of occurring in nature regenerative resource destabilizing factor just.
