Description
Technical field
The present invention relates to locomotive technology field, particularly the novel electric power system of a kind of diesel locomotive and diesel locomotive.
Background technology
The electric control system of diesel locomotive mainly comprises traction system and ancillary system, and wherein, traction system comprises again the equipment such as traction convertor, traction electric machine, and traction convertor, for providing the power supply of variable-frequency variable-voltage to traction electric machine, travels to drive diesel locomotive.Ancillary system comprises auxiliary power supply system again, auxiliary power supply system is one of important component part in diesel locomotive electric system, and the electricity consumption of the electricity consumption of the brake system air compressor electric motor of diesel locomotive, the electricity consumption of control system, Lighting System, synchronous traction generator excitation and battery charge lamp are all provided by auxiliary power supply system.
At present, the auxiliary power supply system of diesel locomotive is all from auxiliary generator power taking, traction convertor is the rectifying device power taking from main generator and electrical generator rear class, for the diesel locomotive of this configuration, need outfit main generator and an auxiliary generator, not only cause system configuration complicated, cost is high, add complete vehicle weight, also add fuel oil consumption, economy is poor.Therefore, along with the development of constantly bringing forth new ideas of field of track traffic, need a kind of more novel, more succinct diesel locomotive to power configuration.
Summary of the invention
The object of the invention is to overcome the above-mentioned deficiency of prior art and provide a kind of cost low, lightweight, configuration is simple, the novel electric power system of a kind of diesel locomotive consuming energy low and diesel locomotive.
Technical scheme of the present invention is:
The novel electric power system of a kind of diesel locomotive of the present invention, comprise auxiliary power supply system and traction convertor, the direct-flow input end of described auxiliary power supply system is connected with the direct-flow input end of traction convertor, is powered after the rectifying device rectification of rear class by main generator for auxiliary power supply system and traction convertor.
Further, the direct-flow input end of described auxiliary power supply system is connected on the DC bus of traction convertor, and described main generator accesses DC bus after the rectifying device rectification of rear class.
Further, the mouth of described auxiliary power supply system connects multiple electric load.
A kind of diesel locomotive of the present invention, comprises the novel electric power system of aforesaid diesel locomotive.
The present invention compared with prior art has following features:
(1) car load only need configure a main generator, eliminates auxiliary generator, simplifies Full Vehicle System configuration, alleviates complete vehicle weight, reduce integral vehicle cost;
(2) reduce the fuel oil consumption of main generator, saved portion of energy, achieved energy-saving and emission-reduction.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, detailed construction of the present invention is further described.
As shown in Figure 1: the novel electric power system of a kind of diesel locomotive, comprise auxiliary power supply system and traction convertor, the direct-flow input end of auxiliary power supply system is connected with the direct-flow input end of traction convertor, is powered after the rectifying device rectification of rear class by main generator for auxiliary power supply system and traction convertor; The mouth of auxiliary power supply system connects multiple electric load.
Particularly, the direct-flow input end of auxiliary power supply system is connected on the DC bus of traction convertor, main generator accesses DC bus after the rectifying device rectification of rear class, auxiliary power supply system and traction convertor is made to form the power-supplying forms of common DC bus, this power-supplying forms eliminates auxiliary generator, only need configure a main generator, enormously simplify car load configuration, reduce integral vehicle cost and complete vehicle weight.In addition, because the DC link of auxiliary power supply system and the DC link of traction convertor are linked together, the braking energy feeding back to DC link during car brakeing can be absorbed by auxiliary power supply system, and then reduce the fuel oil consumption of main generator, save portion of energy, reach the object of energy-saving and emission-reduction.
Wherein, rectifying device, for completing the work of alternating current-direct current change, makes DC bus reach predeterminated voltage.After the DC bus of auxiliary power supply system access traction convertor, DC bus is used for diesel locomotive internal traction system and auxiliary power supply system direct current supply line.
During use, the three plase alternating current sent by main generator is rectified on DC bus through rectifying device, auxiliary power supply system and traction convertor are all from power taking DC bus, auxiliary power supply system is with direct current or exchange the power supply mode exported, and is mainly the driving system in diesel locomotive, air compressor motor, control system, Lighting System, synchronous traction generator excitation and storage battery etc. and provides power supply; Traction convertor is mainly traction electric machine and provides power supply.When diesel locomotive starts braking maneuver, the braking energy that traction electric machine sends in braking procedure feeds back on DC bus, not only stable for the voltage of DC bus, and is utilized by auxiliary power supply system, and then reduce the fuel oil consumption of main generator, save portion of energy.Because the component part of auxiliary power supply system and traction convertor is prior art, repeat no more herein.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, obviously, those skilled in the art can carry out various change modification to the present invention and not depart from the spirit and scope of the present invention.If belong within the scope of the claims in the present invention and equivalent technologies thereof these amendments of the present invention and modification, all belong to protection scope of the present invention.
