The employed power source of the utility model is contact system or storage battery, all is clean energy resourcies, satisfies the requirement of people's energy-saving and environmental protection, low-carbon (LC).Collection traction invertor, subordinate inverter and traction accumulator charge-discharge circuit are one, the integrated level height.Solid die blocking structure is good.
Description of drawings
Fig. 1 is schematic circuit diagram of the present utility model.
Among the figure: 1, traction transformer, 2, the traction transformer precharge unit, 3, four-quadrant rectifier, 4, direct current intermediate circuit, 5, traction PWM inverter, 6, auxiliary PWM inverter, 7, charging module, 8, the traction accumulator precharge unit, 9, the traction accumulator group, 10, integrated traction convertor, 11, absorbing resistor, 12, phase asynchronous traction electric machine, 13, Central Processing Unit (CPU), 14, traction mode change-over swith, 15, locomotive, 16, the 25kV contact system.
The specific embodiment
Control setup of the present utility model includes locomotive 15, traction transformer 1, traction accumulator group 9, integrated traction convertor 10, Central Processing Unit (CPU) 13, and traction mode change-over swith 14 is electrically connected to be formed.The input end of traction transformer 1 is connected with 25kV contact system 16, and mouth is connected with integrated traction convertor 10; Integrated traction convertor 10 is by traction transformer precharge unit 2 and traction accumulator precharge unit 8, direct current intermediate circuit 4, and charging module 7, four-quadrant rectifier 3, traction PWM inverter 5, auxiliary PWM inverter 6 and absorbing resistor 11 are electrically connected to be formed.
The mouth of integrated traction convertor 10 is connected in phase asynchronous traction electric machine 12, Central Processing Unit (CPU) 13 and traction mode change-over swith 14.
When locomotive 15 during by 25kV contact system 16 power supply, traction, electric energy enters direct current intermediate circuit 4 through inferior limit winding, traction transformer precharge unit 2, the four-quadrant rectifier 3 of traction transformer 1, being divided into 3 the tunnel: the one tunnel thus is three-phase alternating-current supply through 5 inversions of traction PWM inverter, drives phase asynchronous traction electric machine 12 and Central Processing Unit (CPU) 13 and advances; Auxiliary PWM inverter 6 inversions of one road warp are three-phase alternating-current supply, supply locomotive 15 ancillary systems; One the tunnel is traction accumulator group 9 charging through charging module 7, and traction accumulator precharge unit 8 disconnects.During regenerative brake, regenerated energy is by traction transformer 1 feedback electrical network.
When locomotive 15 during by traction accumulator group 9 power supply, traction, electric energy is through traction accumulator precharge unit 8, direct current intermediate circuit 4, for traction PWM inverter 5, auxiliary PWM inverter 6 provide direct supply; Glancing impact, regenerated energy is fed back to direct current intermediate circuit 4 through traction PWM inverter 5, and one the tunnel provides the electric energy of auxiliary PWM inverter 6, and one tunnel process charging module 7 is 9 chargings of traction accumulator group, glancing impact, traction accumulator precharge unit 8 disconnects; If the voltage that this operating mode Central Processing Unit (CPU) 13 detects direct current intermediate circuit 4 is higher than setting value, illustrate that regenerating braking energy can't be absorbed fully by auxiliary PWM inverter 6 and traction accumulator group 9, then control system drops into absorbing resistor 11, with excess energy consumption.
Traction transformer precharge unit 2 and traction accumulator precharge unit 8 are by 13 interlockings of locomotive 15 Central Processing Unit (CPU)s, and promptly any moment has only 1 winding logical, drops into simultaneously to avoid traction accumulator group 9 and traction transformer 1.Traction accumulator precharge unit 8 and charging module 7 are by 13 interlockings of locomotive 15 Central Processing Unit (CPU)s, and charging module 7 is open-minded when promptly charging, and traction accumulator precharge unit 8 is turn-offed, and is opposite during discharge.
By above-mentioned control, locomotive can be implemented in 2 kinds of change working under the power supply.
Locomotive 15 is made of the main gear circuit of AC-DC-AC 25kV contact system 16, traction transformer 1, integrated traction convertor 10, phase asynchronous traction electric machine 12 and Central Processing Unit (CPU) 13; Constitute directly-hand over the main gear circuit by traction accumulator group 9, integrated traction convertor 10, phase asynchronous traction electric machine 12 and Central Processing Unit (CPU) 13; The two common DC intermediate loop 4.During the locomotive traction operation, traction accumulator group 9 does not drop into simultaneously with traction transformer 1.2 kinds of circuit all can be implemented as 2 phase asynchronous traction electric machines 12 and Central Processing Unit (CPU) 13 power supplies on the same bogie truck.
In locomotive 15, be provided with traction mode change-over swith 14 and locomotive Central Processing Unit (CPU) 13.
The foregoing description only to 2 traction electric machine power supplies of same bogie truck, if traction transformer increases by one limit winding and increases by one group of traction accumulator, a drag current transformer module, can be realized 2 traction electric machine power supplies to another bogie truck.Because adopt two to overlap independently intermediate dc loop, locomotive major loop redundancy is good.
