Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.
Device embodiment one:
See Fig. 1, this figure is train provided by the invention undue phase energy re-use device embodiment one schematic diagram.
The device of the undue phase energy recycling of the train that the present embodiment provides, comprising: electrical motor 100 and controller 200;
Described controller 200, for determining the undue phase time of train, controlling described electrical motor 100 and working in Generator Status;
Described electrical motor 100 is coaxially connected with train, drives described electrical motor 100 to rotate, make electrical motor 100 work in Generator Status in train driving process, and mechanical energy being converted to electric energy is that consumer on train powers 300.
In prior art, the undue phase time of train, can not the consumer of power-off be powered by storage battery, and other consumer is stopped power supply, such as air-conditioning, like this when air-conditioning power-off, during the broiling summer or the winter of cold, the comfort level of passenger can reduce.Therefore, the method that the present embodiment provides can ensure that all consumers normally use not power-off at the undue phase time of train.
Be understandable that, train is at undue phase time, although pantograph lowers, train and contact system have been isolated, can not from overhead current collection, and train, still in operation, does not stop.Make use of train in the embodiment of the present invention just to continue to run this mechanical energy, this mechanical energy is converted to electric energy.
Because the electrical motor on train and train are coaxial connections, the moving velocity of train is consistent with the selection speed of electrical motor, therefore, control electrical motor to use as electrical generator, mechanical energy is converted to electric energy, for the consumer on train is powered, so just as prior art, some consumer need not be stopped because the delivery of storage battery is limited, the device provided due to the present embodiment can provide electric energy, therefore, train is at undue phase time, and the consumer on car can use as usual, thus can improve the comfort level of passenger.
Device embodiment two:
See Fig. 2, this figure is train provided by the invention undue phase energy re-use device embodiment two schematic diagram.
Be understandable that, the undue phase energy re-use device that the embodiment of the present invention provides can apply the equipment that train has been arranged to greatest extent, needs the equipment of increase just fewer like this, can reduce costs to greatest extent.
Be understandable that, train does not have undue phase time, and train is powered by contact system, and the electric energy that the consumer on train is come by contact system by independent changer is powered.And the device that the present embodiment provides, train at undue phase time, the consumer on train not by changer from contact system power taking, and be through subordinate inverter that the present embodiment provides and auxiliary transformer carrys out power taking from electrical generator.
The train that the present embodiment provides undue phase energy re-use device, also comprises: two-way inverter 400, subordinate inverter 500 and auxiliary transformer 600;
Described controller 200, for determining the undue phase time of train, controlling described two-way inverter 600 and working in rectifier state;
Be understandable that, two-way inverter 600 can work in rectification mode, can work in inverter mode again, just can change its mode of operation by the impulse singla of the switching valve changing two-way inverter 600 brachium pontis.
It should be noted that, two-way inverter 600 is the equipment that train has existed, and in train driving process, can provide source of AC thus provide the power of advance for train for train, in addition, when train braking, can reclaim the electric energy that train braking produces.
The electric energy that described electrical motor 100 exports is that direct current is to intermediate dc loop 500 through the rectification of described two-way inverter 600;
Described subordinate inverter 600, for by the DC inversion on described intermediate dc loop 500 for exchange;
Described auxiliary transformer 700, for the consumer 300 on train is powered after transformation is carried out in the interchange for described subordinate inverter 600 being exported.
The electric energy exported due to electrical motor 100 directly can not supply consumer, therefore, needs to carry out unsteady flow to electric energy, i.e. first rectification, then inversion.Now, two-way inverter 400 uses as rectifier, and DC inversion is interchange by subordinate inverter 600, but the alternating-current voltage/AC voltage that subordinate inverter 600 exports is still too high, therefore, need auxiliary transformer 700 to carry out step-down, the voltage after step-down is powered to consumer.
Device embodiment three:
See Fig. 3, this figure is the circuit diagram of train provided by the invention undue phase energy re-use device embodiment three.
The train that the present embodiment provides undue phase energy re-use device, also comprises: vacuum breaker 10, main transformer 900, contactless switch 20 and rectifier 800;
The former limit winding of described main transformer 900 connects contact system by described vacuum breaker 10;
The vice-side winding of described main transformer 900 connects the input end of described rectifier 800 by described contactless switch 20;
The mouth of described rectifier 800 connects described two-way inverter 400 by described intermediate dc loop 500;
Described controller (not shown), also for determining the undue phase time of train, controlling described contactless switch 20 and disconnecting.
When train does not have undue phase time, contactless switch 20 closes, and the ac high voltage source that contact system is come provides power supply through rectifier 800, two-way inverter 400 to electrical motor 100, and electrical motor 100 drives train driving.
When the undue phase time of train, contactless switch 20 disconnects, controller control electrical motor 100 as electrical generator use, the alternating current sent through two-way inverter 400, subordinate inverter 600 and auxiliary transformer 700 for consumer is powered.
Be understandable that, described auxiliary transformer 700 is three-phase alternating current 380V voltage transformer, the former limit winding of described auxiliary transformer 700 and the connection mode of vice-side winding are star-triangle joint, as shown in Figure 3, certainly, except this connection mode, auxiliary transformer 700 can also be other connection modes, can select as required to arrange.
It should be noted that, described electrical motor 100 can be three phase asynchronism induction-motor, can, by changing excitation mode, make it be operated in motoring condition and generating state.
As can be seen from Figure 3, the subordinate inverter 700 that provides of the present embodiment and two-way inverter 400 are three-phase leg inverter.Rectifier 800 is two-phase leg inverter.
