Description
Technical field
The present invention relates to track traffic electric drive technology field, especially a kind of battery trolley locomotive that adopts unified Voltage-output and two-way DC/DC module.
Background technology
Electric storage battery Dual-energy source engineering truck has advantages of the environmental protection such as low noise, zero-emission, had in recent years the novel car type of development as of flourish track traffic, substitute a large amount of internal combustions type locomotive of shunting, China reaches world-class levels in this vehicle research and development application.
In existing vehicle design, having some defects, there are two kinds of operating voltage 1500V(stringing power supplies in electric storage battery Dual-energy source car) and 800V(storage battery power supply), and gap is very large. This is for current transformer, design of electrical motor capacity, rated frequency, and efficiency optimization is very unfavorable. Full Vehicle System is in the time of mains supply, and cubic power is relatively wasted, and cubic power performance is not enough in the time of storage battery power supply. Current transformer, motor heat waste of capacity are serious, and current transformer input voltage difference is large, affects output voltage waveforms, has a strong impact on this vehicle Optimum Design and service efficiency.
Summary of the invention
In order to overcome existing above-mentioned deficiency, the invention provides a kind of electric storage battery battery trolley locomotive that adopts unified Voltage-output and bidirectional DC/DC module.
The technical solution adopted for the present invention to solve the technical problems is: a kind of battery trolley locomotive that adopts unified Voltage-output and two-way DC/DC module, comprise 1500V power supply and 800V power supply, 1500V positive source connects fuse successively, contactor, the first current transformer and high-speed circuit breaker, 1500V power cathode connects the second current transformer, 800V positive source connects battery isolating switch successively, the 3rd current transformer, inductance L 1, the second insulated gate bipolar transistor IGBT 2(T2, D2), the first current transformer and high-speed circuit breaker, 800V power cathode connects the second current transformer, between the 3rd current transformer and inductance L 1, be parallel with the first voltage transformer, inductance L 1 and the second insulated gate bipolar transistor IGBT 2(T2, D2) between, be parallel with the first insulated gate bipolar transistor IGBT 1(T1, D1), the second insulated gate bipolar transistor IGBT 2(T2, D2) between and the first current transformer, be parallel with successively capacitor C and second voltage transformer.
The invention has the beneficial effects as follows, two-way DC/DC circuit is recently to apply increasingly extensive electronic circuit system, by adopting, to have overcome the design power that two voltage brings current transformer, design of electrical motor after a set of two-way DC/DC circuit large for we, efficiency is low, the shortcomings such as inversion wave distortion, and element, volume does not increase (identical with original number of elements), and current transformer power reduction half is that cost reduces greatly, motor cost, the corresponding reduction of volume, advanced person possesses skills, performance optimization, the promotional value of product up-gradation.

Detailed description of the invention
If Fig. 1 is structural representation of the present invention, a kind of battery trolley locomotive that adopts unified Voltage-output and two-way DC/DC module, comprise 1500V power supply 1 and 800V power supply 2, 1500V power supply 1 positive pole connects fuse 3 successively, contactor 4, the first current transformer 5 and high-speed circuit breaker 6, 1500V power cathode connects the second current transformer 7, 800V power supply 2 positive poles connect battery isolating switch 8 successively, the 3rd current transformer 9, inductance L 1, the second insulated gate bipolar transistor IGBT 2(T2, D2), the first current transformer 5 and high-speed circuit breaker 6, 800V power supply 2 negative poles connect the second current transformer 7, between the 3rd current transformer 9 and inductance L 1, be parallel with the first voltage transformer 10, inductance L 1 and the second insulated gate bipolar transistor IGBT 2(T2, D2) between, be parallel with the first insulated gate bipolar transistor IGBT 1(T1, D1), the second insulated gate bipolar transistor IGBT 2(T2, D2) between and the first current transformer 5, be parallel with successively capacitor C and second voltage transformer 11.
Operation principle:
In the time that contact net is worked:
1500V powers to traction convertor, and charges to traction accumulator. Now two-way DC/DC turn-offs in step-down state (Buck): T1, and T2 carries out open and close work by dutycycle. When T2 conducting, Uc passes through L1, T2, and battery forms loop, L1 energy storage; In T2 when cut-off,, L1 is by D1, and battery forms discharge loop, the continuous conducting of T2, and cut-off, Ub produces the voltage lower than UC, and amplitude is by the dutycycle of T2, and makes UBRequire and change according to various charge in batteries electric current and voltages, battery being carried out to constant voltage, constant current or floating charge;
In the time of contactless net voltage, battery output power supply:
Two-way DC/DC turn-offs in pressure-increasning state (Boost): T2, the cut-off of T1 alternate conduction. When T1 conducting, power supply Ub charges to inductance L 1 by T1. Then T1 cut-off, L1 charges to capacitor C by D2, makes capacitor C voltage higher than battery tension Ub, the continuous conducting of T1, cut-off, and control conduction ratio, make UCThe constant 1500V that remains on. So just ensured that traction convertor always works in 1500V voltage, traction electric machine is also operated in the duty of corresponding rated voltage.
More than explanation is just illustrative for the purpose of the present invention; and nonrestrictive, those of ordinary skill in the art understand, in the case of not departing from the spirit and scope that claims limit; can make many amendments, variation or equivalence, but all will fall within the scope of protection of the present invention.
