Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As shown in Figure 3, the electric supply installation of carriage air conditioner unit described in the utility model, comprise locomotive power supply device 1, be arranged on the inverter power supply device 2 in every joint compartment and be arranged on 1 to 2 air-conditioning unit 3 in every joint compartment, locomotive power supply device 1 is to air-conditioning unit 3 and inverter power supply device 2 output DC600V direct currents.
The inside of air-conditioning unit 3 has a supply unit, and supply unit is used for providing needed power supply to each load of air-conditioning unit 3.In the present embodiment, the supply unit input of air-conditioning unit 3 is connected with the output of locomotive power supply device 1, be that air-conditioning unit 3 directly adopts the DC600V power supply, this kind supply power mode, do not need to change structure and the system of air-conditioning unit 3, can transform on the basis of original air-conditioning unit 3, can reduce improvement cost.
As shown in Figure 4, the supply unit of air-conditioning unit 3 comprises variable frequency inverter 5 and DC filter 6, the input of DC filter 6 is connected with the DC600V output of locomotive power supply device 1, the output of DC filter 6 is connected with the input of variable frequency inverter 5, and the output of variable frequency inverter 5 is connected with compressor, condensation fan, ventilation blower even load 8.Variable frequency inverter 5 frequency converters in the air-conditioning unit supply unit adopt VVVF control, change the DC600V direct current into load 8 needed alternating currents, to each load 8 power supply of air-conditioning unit 3.On the passenger train of part vehicle, the output of locomotive power supply device 1 can be serially connected with DC filter, in such cases, just DC filter 6 can be set again in the supply unit of air-conditioning unit 3.
Air-conditioning unit 3 has omitted the switching device that interchange in the existing air-conditioning unit turns direct current, directly uses variable frequency inverter 5 to change direct current into load 8 required alternating current, and variable frequency inverter 5 is replaced by 1700V by original 1200V and gets final product.
Air-conditioning unit 3 adopts variable frequency control, and compressor adopts frequency-changeable compressor, and condensation fan and ventilation blower all adopt frequency conversion fan.Frequency conversion control technique is prior art, elaborates no longer in addition here.
Existing rail vehicle air conditioner group mostly adopts constant speed air-conditioning unit, and constant speed air-conditioning unit starting current is large, and is large to power surges, affects other electric equipment.And the convertible frequency air-conditioner unit is the low pressure low frequency when starting, and electric current is little, and starting current is 0 substantially, and without impact, reliability significantly improves to power supply.
The constant speed air-conditioning is kept the guest room temperature by constantly switch control start/stop of compressor, and temperature fluctuation is large.Convertible frequency air-conditioner is kept the guest room temperature by the running frequency minimizing ability that reduces compressor, and temperature fluctuation is little, and more consistent with each other with UIC553 control curve, comfortableness significantly improves.
As shown in Figure 3, the input of inverter power supply device 2 is connected with the output of locomotive power supply device 1, the DC600V dc inverter that inverter power supply device 2 provides locomotive is alternating current output, the output of inverter power supply device 2 comprises 3 phase AC380V and/or single-phase AC220V and/or DC110V and/or DC24V, is used for to power supplies such as other low-capacity electric equipment 7, control system and storage batterys 4.Still adopt the processing of original power supply direct current and link of protection, isolated from power voltage stabilizing link, power supply is stabilized in DC600V, reduce the capacity of inverter power supply device, save or reduce isolating transformer.
As shown in Figure 3, because air-conditioning unit 3 is powered by 3 phase AC380V of the prior art, change to the DC600V powered by direct current of direct use locomotive power supply device 1 output, through the variable frequency inverter in the air-conditioning unit supply unit, DC600V is flowed electricity change the needed alternating current of load into, to each load supplying of air-conditioning unit.Therefore air-conditioning unit 3 no longer needs inverter power supply device 2 that the 380V alternating current is provided, requirement according to other power consumption equipment of vehicle (putting etc. such as exhaust blower, companion's hot charging), 3 phase AC380V can directly cancel or reduce capacity, only need very little capacity can satisfy the demand of other power consumption equipment, the capacity of inverter power supply device 2 can be lower than 20KW, in the general situation, the capacity of inverter power supply device 2 only needs 15KW to get final product.Because the significantly reduction of inverter power supply device 2 capacity causes the volume of inverter power supply device 2 significantly to reduce, weight also can significantly alleviate, and correspondingly also reduces the acquisition cost of inverter power supply device 2.
The capacity of existing inverter power supply device 2 is approximately 35KW, and weight is 600Kg, and in the present embodiment, because air-conditioning unit 3 does not use inverter power supply device 2,2 of inverter power supply devices can be decreased to 15KW, and weight is about 100Kg, and the weight of an inverter power supply device 2 can reduce 500Kg.As joining 1 inverter power supply device 2 by every joint compartment, every joint compartment loss of weight 500Kg then, every row subway generally are furnished with 18 joint compartments, and then the total loss of weight of every row subway reaches 9000Kg.As joining 2 inverter power supply devices 2 by every joint compartment, every joint compartment loss of weight 1000Kg then, every row subway generally are furnished with 18 joint compartments, and then the total loss of weight of every row subway reaches 18000Kg.
In addition, existing capacity is the inverter power supply device 2 of 35KW, and the price of its separate unit is about 180,000 yuan, and in the present embodiment, because the capacity of inverter power supply device 2 is decreased to 15KW, the price of separate unit then is about 60,000 yuan, and every inverter power supply device 2 can be saved 120,000 yuan of costs.As joining 1 inverter power supply device 2 by every joint compartment, then every joint compartment is saved 120,000 yuan, and every row subway generally is furnished with 18 joint compartments, and then always to save cost be 2,160,000 yuan to every row subway.As joining 2 inverter power supply devices 2 by every joint compartment, then every joint compartment is saved 240,000 yuan, and every row subway generally is furnished with 18 joint compartments, and then always to save cost be 4,320,000 yuan to every row subway.
In the present embodiment, air-conditioning unit 3 adopts variable frequency control, than constant speed air-conditioning unit of the prior art electrical energy saving approximately 30%.Air-conditioning unit take refrigerating capacity as 29KW is example, as using 150 days according to every air-conditioning unit is annual, used every day 15 hours, per hour the every degree electricity of power consumption 14.5KW is by 0.8 yuan of calculating, the constant speed air-conditioning unit then electricity charge of annual power consumption is about 150 * 15 * 14.5 * 0.8=26100 unit, and the convertible frequency air-conditioner unit then expense of annual economize on electricity is about 26100 * 30%=7830 unit.
Every row railcar is joined 18 compartments, and two air-conditioning units are joined in each compartment, and then reducing expenses every year is about 28.2 ten thousand yuan.
As mentioned above, given scheme content can derive similar technical scheme by reference to the accompanying drawings.In every case be the content that does not break away from technical solutions of the utility model,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does according to technical spirit of the present utility model.
