The present invention is a kind of new-type generator, adapts to require generator can be fully loaded with the output generating under the slow-speed of revolution, requires the output work ratio, presents the electric energy ratio, and electromechanical conversion efficiency is higher than existing generator.This generating function is made ac square wave, sinusoidal wave dual-purpose form.Adopt the comparable sinusoidal wave more electric energy that sends of ac square wave, square wave incompatibility inductive load and transformer transmission of electricity, but can adapt to resistive load and rectified load, as the direct current electric system of family expenses, industrial electric heater, high voltage direct current transmission and the various types of vehicles.Can improve whole generating-transmission of electricity, the cost of the efficient of using electricity system and reduction system.
Description
The distinguished key technology of this generator is to have adopted high efficiency continuous ac square wave to send generating, and the each harmonic composition of sinusoidal ac has the trend of increase under the saturated situation of armature coil magnetic flux.The present invention utilizes this point, and single-phase or three-phase electric work output line seals in the magnetic flux that changes in the capacitor of suitable capacity and the current cycle process and voltage and forms abundant multi-harmonic-oscillations composition and all change the energy of electromagnetic conversion into square wave ac and send out to sending outside at generator.To be still sinusoidal wave way different with sealing in capacitor compensation power factor current waveform for these.And sealing in capacitor, to obtain continuous ac square wave be the simplest a kind of, method that cost is minimum, obtained following technique effect:
One, when same output voltage, adopts the comparable sine wave of square wave to send more and send out 1/5 or 1/3 electric energy.Motor merit ratio, electric efficiency and electromagnetic conversion efficient are higher than sine wave, and this point is more outstanding at low-power machine.
Two, generator adopts square wave to have the fully loaded output performance of the excellent slow-speed of revolution.Square wave ac does not have maximum, the branch of mean value, effective value.Compare its electric current envelope component of square wave less than square wave with sinusoidal wave maximum.Compare power factor (PF) less than square wave with effective value mean value and square wave, with the corresponding square wave of mean value effective value, its maximum must be higher than square wave, that is to say: the square wave power factor draws with the product of power divided by voltage and current.Sinusoidal wave power factor must draw with the product of active power divided by voltage and current.Because generator voltage is proportional to rotating speed, that is to say that the rotating speed that sinusoidal wave generating must be bigger just can reach current/voltage value and the power factor that is equivalent to square wave, equaling square wave can fully loaded output under lower than sine wave rotating speed.The motor that this slow-speed of revolution can be fully loaded with generating is very important for wave power, wind-force, tidal force, the ocean current power of utilizing low flow velocity and the various thermo-mechanical power generations that often are in low-speed running.Because gear can be simplified or omit to this motor, reduce the cost of power one Blast Furnace Top Gas Recovery Turbine Unit (TRT).Improve probability and utilance.According to single-phase 220 volts 60 watts of the permanent magnet excitations of making, 120 watts and excitatory 380 volts of 400 watts of three kinds of The prototype test results of three-phase electricity.Can accomplish: one, the employing square wave is comparable exports at full capacity with sinusoidal wave low 1/3 or 1/2 rotating speed.Two, depress comparable sine wave with square wave in same electrical and send 1/5 or 1/3 electric energy more.Three, be higher than sinusoidal wave generating with square wave motor electromagnetic one mechanical energy conversion efficiency and motor merit ratio.Above-mentioned experimental prototype seals in electric capacity between motor and load can do the use of square wave generator.Be not connected in series electric capacity and can make sine wave generator usefulness, so model machine has the function that sends two kinds of waveform alternating currents, can adapt to resistive, rectification and inductive unequally loaded needs.With 60 watts of permanent magnet excitation prototype test simulation wind power generations,, be equivalent to wind slurry per second two commentaries on classics (about fresh breeze) 220 volts of fully loaded outputs of 60 watts of ac square waves with 1: 8 gear graduation.Because the saturated pressure stabilization function of magnetic flux, electric capacity is to the metering function of superpotential absorption and AC machine itself, and the full load rotating speed rises to 3 times, and voltage rises and do not cross 20%, 1/3 load above 25%
Even short circuit current does not increase yet, general P=I
2R, the voltage of increase can not become active power, can not cause overload to damage to electrical equipment, and 220V, 60W model machine use 45W, and 6V hand tractor fly wheel generator makes into, seals in 4 microfarad electric capacity and transforms square wave generating increase 15W power into, and it is fully loaded to reduce by 1/3 rotating speed.400W three-phase square wave generator adopts electricity to swash its output voltage of electromagnetism and can adjust.Be to change 350 watts of 12V automobile claw pole formula generators with 2500 to make into, when sending generating 1500 to change with square wave 380 volts, 400 watts watts fully loaded, relatively reduces by 1/3 rotating speed with the primary sinusoid generation mode and be fully loaded with.Increase and export electric work more than 50 watts.120 watts of single-phase 220 volts of model machines of permanent magnet excitation are changed a social system with former 90 watts of 12V magneto alternators.With square wave at former rotating speed one half 220 volts 120 watts fully loaded outputs.Comprehensive above-mentioned result of the test proof square wave sends electricity and lies prostrate in sine wave.
Utilize this technology to make and produce following generator
One, makes magneto or the electric excitation type household wind-driven generator that single household uses.With this energy of being convenient to draw of development and utilization wind energy, make the special-purpose high merit ratio of all kinds vehicles, slow-speed of revolution rectangular-wave alternating-current generator.Make the high merit ratio in the movable type of various different capacities, voltage, fixed power station, square wave, sinusoidal wave dual-purpose generator.
Two, in this invention generator because condenser capacity Q
C, voltage V, electric current I, magnetic flux φ, frequency f
nAll be the proportional variation of variable that links mutually, so this generator has the characteristic of a preciousness: the rotating speed of the high more fully loaded needs of the voltage that sends is also just low more with regard to cost and cost more little, unit.This specific character makes the generator of this technology manufacturing generate electricity wind power generation, wave power generation, generating electricity by natural energy such as ocean current power, tidal force than the inland river weir low-head hydraulic that other generator more can adapt to the slow-speed of revolution, high pulling torque power.Equally also adapt to and utilize the low temperature difference, be in Stirling engine and titanium promise memorial alloy engine difficult to understand and other thermo-mechanical power generation of slow-speed of revolution running.By formula: I=(U)/(R) and Q=(ω
OL)/(R)=1/ (ω
0CR); Utilize this technology capacitor to be made the form and the superconducting generator armature coil polyphone of superconduction, so just can be formed in fully loaded generating under the utmost point slow-speed of revolution, efficient approaches 1 superconduction rectangular-wave alternating-current generator, and the high-power square wave ac that above-mentioned each machine sends can directly utilize high-power high voltage voltage multiplying rectifier device to become high voltage direct current and outwards present.
