By adopting centralized auxiliary power supply, the utility model greatly improves the safety and reliability.
Description
Technical field
The utility model relates to a kind of electric power system, the high-power centralized auxiliary power supply system of particularly a kind of EMU.
Background technology
In the high speed railway transportation equipment, the auxiliary power supply system technical relation is to the safety of high speed railway transportation equipment and reliability and passenger's traveling comfort.For example, EMU, high-power centralized auxiliary power supply system technology, to guaranteeing the reliability service of train traction system, safety system, the traveling comfort that improves the passenger is extremely important.Existing auxiliary power supply system all is to adopt decentralized power-supply, so its safety and reliability are lower.
The utility model content
For addressing the above problem, the utility model provides a kind of safety and the high high-power centralized auxiliary power supply system of EMU of reliability.
The high-power centralized auxiliary power supply system of the utility model EMU, wherein: each traction unit comprises two traction convertors and two AuCTs, two described traction convertors of each described traction unit are connected with two described AuCTs of this unit simultaneously, and all described AuCTs are all exported the AC440V power supply by power supply buses to permutation train bus;
Described AuCT is divided into single AuCT and two AuCT, described pair of AuCT provides AC440V power supply for coupled battery charger, described battery charger links to each other with storage battery, and the mouth of described battery charger and described storage battery is connected to direct current supply rail simultaneously.
The high-power centralized auxiliary power supply system of the utility model EMU, wherein: described direct current supply rail is divided into BN1, BN2, BD three tunnel, a DC load part is by the direct current supply rail power supply of BC04 car, and another part is by the direct current supply rail power supply of FC05 car.
Therefore the high-power centralized auxiliary power supply system of the utility model EMU has improved safety and reliability greatly owing to adopt centralized auxiliary power supply, and crossing that phase-separating section space-time transfers can continuous working, has reduced fault rate; When crossing phase-separating section storage battery greatly electric current the discharge of the DC load of car load has been reduced fault rate, more important is the quantity that has reduced storage battery, has improved the economy of motor train unit.
Description of drawings
Fig. 1 is the scheme drawing of the high-power centralized auxiliary power supply system of the utility model EMU.
The specific embodiment
Below in conjunction with Figure of description the high-power centralized auxiliary power supply system of the utility model EMU is described further.
Referring to Fig. 1, the high-power centralized auxiliary power supply system of the utility model EMU, wherein: each traction unit comprises two traction convertors 1 and two AuCTs, the DC3000V direct-flow intermediate circuit of traction convertor 1 is as the power supply of AuCT, two traction convertors 1 of each traction unit are connected with two AuCTs of this unit simultaneously, when traction convertor 1 fault, another can continue to have realized the auxiliary power supply redundancy to the AuCT power supply like this.AuCT has been realized networking, and all AuCTs are all exported the AC440V power supply by power supply buses to permutation train bus.
Because the control system of train adopts the DC110V power supply, therefore AuCT is divided into single AuCT 2 and two AuCT 3, two AuCTs 3 provide AC440V power supply for coupled battery charger 5, battery charger 5 links to each other with storage battery 4, and battery charger 5 is connected to the DC110V direct current supply rail simultaneously with the mouth of storage battery 4.It is that storage battery 4 chargings are the DC110V electric simultaneously that battery charger 5 becomes the DC110V power supply with the AC440V power source conversion.
In order to improve the reliability of load, direct current supply rail is divided into BN1, BN2, BD three tunnel, and a DC load part is by the direct current supply rail power supply of BC04 car, and another part is by the direct current supply rail power supply of FC05 car.For the load of particular importance, adopt direct-connected battery BD uninterrupted power supply.Like this, the DC power-supply system reliability improves greatly.
The high-power centralized auxiliary power supply system of the utility model EMU, when crossing phase-separating section, control system is taked small braking, intermediate DC circuit uninterrupted power supply for the traction convertor 1 of AuCT power supply, the AuCT uninterrupted duty, it is uninterrupted to exchange AC 440V power supply, and battery charger work is uninterrupted.
Therefore the high-power centralized auxiliary power supply system of the utility model EMU has improved safety and reliability greatly owing to adopt centralized auxiliary power supply, and crossing that phase-separating section space-time transfers can continuous working, has reduced fault rate; When crossing phase-separating section storage battery greatly electric current the discharge of the DC load of car load has been reduced fault rate, more important is the quantity that has reduced storage battery, has improved the economy of motor train unit.
Above embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineering staff in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
