Present gas-electricity power combined bus is made up of gas cylinder, charge valve, filter, pressure reducer, high pressure gauge, electromagnet cut off valve, overcurrent protection valve and pipeline etc.; The gas circuit fastener exists in the operational process and causes the fault that gets loose because of jolting, vibrating, and causes principal fault hidden danger simultaneously.The existing magnetic clutch control mag-dynamo hybrid-power bus that adopts, sparking phenomenon when existing magnetic clutch to combine separately, and gas-electricity power combined bus then is prone to the danger of igniting, exploding if above situation occurs.
Adopt three phase induction generator to replace existing permanent magnetism in the gas-electricity power combined system of the series-parallel connection of the utility model and send out synchronous dynamo, do not need magnetic clutch control generating rotating speed, guarantee the sparking phenomenon can not occur, guarantee vehicle driving safety; Three phase induction generator not only adopts converter technique simultaneously, and alerting ability is high, easy to maintenance, and speed governing is convenient and performance is good; Have characteristics such as cost is low, control is simple, technology maturation, have to application prospects.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the utility model based on the pneumoelectric series-parallel hybrid electric system of three phase induction generator.
The specific embodiment
Below in conjunction with the specific embodiment the utility model is done further detailed explanation.
As shown in Figure 1; The utility model is based on the pneumoelectric series-parallel hybrid electric system of three phase induction generator; It comprises driving engine 1, electrical motor 2, electrical generator 3, drive axle 4, an above super capacitor group 5 and a controller 6, and said driving engine 1 is driven by natural fuels, and the one of which end is connected with electrical motor 2 one ends by power-transfer clutch 7; Electrical motor 2 other ends connect drive axle 4, and driving engine 1 other end drives electrical generator 3 by belt-driving; Controller 6 one ends connect electrical generator 3 and electrical motor 2 respectively, and controller 6 other ends connect super capacitor group 5, and said electrical generator 3 is a three phase induction generator.
In the utility model, driving engine 1 a developed power part flows to drive axle 4 through mechanical drive, and another part then drives three phase induction generator 3 generatings.The electric energy that three phase induction generator 3 sends is flowed to electrical motor 2 and is driven or directly flow to super capacitor group 5 by controller 6 controls, and the drive torque that electrical motor 2 produces sends drive axle 4 to through the power set composite.
When the rotation speed n of three phase induction generator 3 rotors is lower than synchronous speed n1=60f/p, a revolutional slip S=(nl-n)/n is arranged between them, < s < 1 for the operating range 0 of electrical motor 2; Wherein f is an electric voltage frequency, and p is a motor progression, n1 be rotor speed (change/>min); N be the stator field rotating speed (change/min); If this moment, 3 work of driving engine 1 band three phase induction generator make its rotation speed n be higher than the rotating field rotating speed, and the value of revolutional slip s were less than zero; Also cutting rotor conductor of rotating field this moment, just its relativeness is opposite with electrical motor 2 mode of operations.The electromagnetic torque of this moment is a braking character, and driving engine 1 must overcome this lock torque just can make the rotor rotation.Driving engine 1 has been done merit in this process, and driving engine 1 makes the mechanical energy on the motor reel change the electric energy that stator winding transfers to super capacitor group 5 into.At this moment electrical motor is operated in the electrical generator state, and its active volt-amperes is provided by three phase induction generator 3; Obtain reactive volt-amperes through strive forward magnetic power own.
