In some embodiments, when diesel locomotive is passenger locomotive, the diesel locomotive can also include train power supply
System 62, which is used to power to compartment, i.e., to interior vehicular illumination equipment, air-conditioning system, 220V socket etc.
Electric energy is provided.So the generator 22 on passenger locomotive is in addition to providing electric energy to main transmission 25 and accessory drive system 28
Outside, also electric energy is provided to power supply system of train 62.Specifically, auxiliary intermediate dc circuit 27 receives the direct current of second voltage
After electricity, not only by the direct current electricity output of the second voltage to accessory drive system 28, also the direct current electric car of second voltage is gone out to give
Power supply system of train 62, to guarantee that power supply system of train 62 can operate normally.
Wherein, when main transmission 25 breaks down, and generator 22 is caused to stop issuing the first alternating current, auxiliary is intermediate
After DC loop 27 receives the direct current of tertiary voltage, not only by the direct current electricity output of the tertiary voltage to accessory drive system
28, also the direct current electric car of tertiary voltage is gone out to power supply system of train 62, to guarantee that example vehicle power supply system 62 can operate normally,
Avoid the generation for the case where entire compartment powers off suddenly caused by breaking down because of main transmission 25.
Optionally, when passenger locomotive dynamic braking, the electric energy that traction electric machine 251 generates, which can also export, gives train power supply system
The second alternating current that system 62, i.e. traction electric machine 251 generate exports after the processing of main inverter 252 is the direct current of the 4th voltage
To main intermediate dc circuit 24, main intermediate dc circuit 24 by the direct current electricity output of the 4th voltage to auxiliary converter device 26, and
26 direct currents that the direct current of the 4th voltage is converted to the 5th voltage are set by auxiliary converter, auxiliary intermediate dc circuit is given in output
27, after auxiliary intermediate dc circuit 27 receives the direct current of the 5th voltage, not only the direct current electricity output of the 5th voltage is given
Accessory drive system 28 also goes out the direct current electric car of the 5th voltage to power supply system of train 62, to reduce the sending of generator 22
Electric energy reaches energy-efficient purpose.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
