Description

A kind of new type electric generator group

What the present invention relates to is a kind of new type electric generator group, belongs to technical field of generators.

Prior art such as small-sized internal combustion thermal power generation unit (patent No. is 96242156.1) and voltage stabilization permanent magneto generator (patent No. is 7235798.X), the former structure is by reacting furnace, heat exchanger, washing filter and internal combustion engine generator group constitute, reacting furnace wherein is a hermetically-sealed construction, its upper end is provided with the coal bin of coal continuously, reacting furnace is communicated with heat exchanger by heating gas outlet and steam inlet, heat exchanger also is communicated with water tank and washing filter respectively by water filling port and low temperature rough gas outlet simultaneously, and the pure coal gas behind washing and filtering uses for the generating of internal combustion engine generator group.It is to reach the voltage stabilizing purpose by the relative position of regulating between rotor and the stator for the latter, and its structure is that two terminations of its center fixation cover are steadily fixed, and its longitudinal axis overlaps with rotor and output shaft of gasoline engine line, and center fixation puts and has slotted eye.The stator of being made up of adjusting screw(rod), sliding nut, stator sliding sleeve, stator, guiding stop bit attachment screw, worm-and-wheel gear, actuating motor moves governor motion, the equalization of strain spring that it is set in the center is compressing the stator sliding sleeve, in order to overcome the suction between rotor and stator.Though above-mentioned two kinds of prior aries respectively have its characteristics, their common defectives are that power consumption is big, has pollution.

The objective of the invention is to the defective at above-mentioned existence, propose a kind of new type electric generator group, it can effectively overcome the defective that prior art exists, and has little, the free of contamination characteristics of power consumption.

Technical solution of the present invention:

Starter motor 2 is arranged; it connects the main shaft of motor 3 by relay adhesive switch 30; motor 3 connects generator 4 by inertial flywheel 13; an output 15 of generator 4 connects the A point in the rectifier filter 5; another output 14 of generator 4 connects the B point in the rectifier filter 5; the input of the high-power voltage stabilizing reducing transformer 6 of output termination of rectifier filter 5; the output of high-power voltage stabilizing reducing transformer 6 accesses the input of sample adjuster 7; three outputs 16 of sampling adjuster 7; 17; 18 corresponding three inputs 19 that connect frequency converter 8; 20; 21; the control end 22 of sampling adjuster 7; 23 connect left alone without help machine switch 10; the signal output part 24 of frequency converter 8; 25; the 26 corresponding base stages that connect three transistors in the frequency-variable module 9; the power output end 27 of frequency converter 8; 28; the 29 corresponding collector electrodes that connect three transistors in the frequency-variable module 9; the emitter correspondence of three transistors in the frequency-variable module 9 connects three inputs 37 of motor 3; 38; 39; the output 14 of generator 4; 15 take over the input that carries protector 11, the anode of the positive termination starter motor 2 of storage battery 12.

Advantage of the present invention:

Energy free, environment purification does not have any emission, the noise decibel measurement is the 1-5 decibel, cost is 60% of a prior art, volume and weight is existing 40-50%, few easy workout part, upkeep cost is low, and is simple and reasonable, make easy to use, applied range.

Accompanying drawing is the embodiments of the invention structural representations

It is 1.5 horsepowers that starter motor 2 among the figure is selected power for use, and operating voltage is 12V; Adjustable frequency motor 3 is selected power 1000W, three-phase, operating voltage 110V for use; Generator 4 is selected power 2000W for use, output voltage 220V; High-power voltage stabilizing reducing transformer 6 and rectifier filter 5 are rectification reduction voltage circuits of a standard, select power 1000W for use; Sampling adjuster 7 is that circuit is adjusted in a sampling, selects MCC-86B-02 for use; Frequency converter 8 is frequency changer circuits, selects model MCC-86A-04 for use; Frequency-variable module 9 usefulness models are MG20G6FC1; Storage battery 12 is selected the storage battery of voltage 12V, electric current 100A for use.

Further describe technical solution of the present invention and bear the course of work below in conjunction with the embodiment accompanying drawing:

The anode of starting switch 1 is that the anode with motor 2 joins, when starting starting switch 1, relay adhesive switch 30 closes, motor 2 is with regard to operate as normal, when the rotating speed of motor 2 reaches per minute 2000-2600 commentaries on classics, with motor 2, motor 3 generator 4 on the main shaft normal power generation that just brings into operation that coexists, the 220-240V voltage of generator 4 outputs is through output 14,15 give rectifier filter 5, rectifier filter 5 is current rectifying and wave filtering circuits of a standard, through rectification, just export the direct voltage of 500V after the filtering, output through rectifier filter 5 inputs to high-power voltage stabilizing reducing transformer 6, voltage is reduced to the voltage of voltage regulation in 110-120V by 500V, export to sampling adjuster 7 then, sampling adjuster 7 also is made up of the sample circuit of a standard, its effect just is sampling and phase-splitting, the direct voltage that is divided into three 110-120V, they are respectively by its output 16,17,18 export to frequency converter 8, frequency converter 8 is made up of three frequency changer circuits, its three frequency change control signals of output and three frequency conversion principal voltage, wherein three frequency change control signals are by its output 24,25,26 export to control (base) utmost point of three transistors in the frequency-variable module 9, three frequency conversion principal voltages are by its output 27,28,29 input to the collector electrode of three transistors in the frequency-variable module 9, frequency-variable module 9 is formed three separate switching circuits by three transistors, they all are silicon triodes, and all be high power valve, three transistors are according to different operating frequency conductings, end, thereby export three alternating voltages and give motor 3 respectively, for motor 3 provides operating voltage, guarantee the operate as normal of motor 3.Be serially connected in the inertial flywheel 13 between generator 4 and the motor 3, its effect is that it just kept the operate as normal of generator 4 when per minute 2000-2600 changeed when motor 2 reaches, guarantee generator 4 output rated voltage 220-240V constantly, frequency is 50-60Hz, and this is by the decision of the rotating speed of generator.Overload protective device 11 is overload protecting circuits commonly used, and the power of present embodiment is 3000W, and the consumption of this machine is 1500W, if load surpasses 1500W, and just tripping operation of overload protective device 11, thus the safety that guarantees unit runs well.
