Description

Alternating current drive work business railcar diesel generator group
Technical field
The present invention relates to work business railcar electrical generator fields, specifically a kind of alternating current drive work business railcar diesel engine hair Motor group.
Background technique
Work business railcar is the important component of railway equipment modernization, is construction of railways, maintenance of equipment, the maintenance of way Important pulling equipment.Since what work business railcar carry railway power supply route speedily carries out rescue work and repair responsibility, so its power one As selection alternating current drive work be engaged in railcar diesel generator group.Wherein, alternating current drive work business rail of the power greater than 300HP Road vehicle be mainly used for the transport of construction material and personnel when railway construction and major repair of track, large-scale maintenance machinery marshalling by guard station to The work such as the round-trip traction and the transfer of construction guard station of construction site.With the continuous promotion of the scale level of railway construction in China, New line construction is carried out using big marshalling and overhaul construction has become the major way of construction of railways, in this way to high-power railcar Demand is also more and more.
Traditional work business railcar is domestic recently as the development of track drawing technology by the way of hydraulic power Work business railcar is done step-by-step AC-DC and hands over straight electric transmission, and develops to AC-DC-AC alternating current drive;Using alternating current The mode of transmission can promote the vehicle performance and reliability of work business railcar, increase the human-computer interaction of driver and Full Vehicle System Ability improves the intelligence and automatic diagnosis capability of trailer system, optimizes the working environment of driver and service worker, reduce track Vehicle runs the pollution level for environment.
Work business railcar develops to alternating current drive, and work business railcar diesel generator group group traditionally selects electrical excitation Synchronous generator mainly includes electrical excitation main generator 1 ', diesel engine 2 ', fairing 3 ' and provides excitation for main generator 1 ' The excitation unit 4 ' of electric current, excitation unit 4 ' are made of field power supply 41 ' and excitation structure 42 ', alternating current drive work business track The rotation of vehicle diesel generator group generates electric power, provides electric energy for alternating current traction system;Alternating current drive work business railcar diesel oil Machine generating set needs to realize the adjustment of revolving speed according to the instruction of driver controller, and generator needs to be passed through according to driver instruction Excitation unit 4 ' adjusts exciting current to realize the adjustment of output voltage, provides electric energy for trailer system;It is superfluous to improve system Yu Xing, excitation unit 4 ' are usually arranged as one cold standby of a job, and the failure of electrical excitation synchronous generator, it will cause Complete vehicle fault influences railcar normal work.Such structure has the disadvantage in that uses additional excitation unit 4 ' first, It will increase the weight of whole generating set, secondly additional excitation unit 4 ' can occupy additional space, furthermore excitation unit 4 ' It is configured with field power supply 41 ', excitation voltage needed for 41 ' voltage of field power supply is greater than main generator 1 ', when excitation unit failure When the excitation voltage over-voltage phenomenon out of control for be easy to causeing main generator output voltage, generate security risk.
Summary of the invention
Present invention seek to address that alternating current drive work business railcar is big using weight caused by electrical excitation main generator, occupies Space is big, exports the technical issues of easy over-voltage.For this purpose, the present invention proposes alternating current drive work business railcar diesel generator Group.
The technical solution adopted by the present invention to solve the technical problems is:
Alternating current drive work business railcar diesel generator group, including being supported on main generator, the driving that work is engaged in railcar The diesel engine of main generator rotor rotation and the fairing being electrically connected with main generator output end, the output of the fairing It holds and is connected with the trailer system of work business railcar, the main generator is magneto alternator.In use, alternating current drive Work business railcar diesel engine drives the rotor rotation of magneto alternator, and magneto alternator generates three-phase alternating current, forever Magnetic-synchro generator output three-phase alternating current is transformed into direct current after fairing, provides electric energy for trailer system.Design When, it is calculated according to the vehicle technical requirements and use condition of railcar and selects diesel engine, according to diesel engine maximum (top) speed and most High power requirements select magneto alternator and relevant design parameter, send out diesel engine permanent-magnet synchronous under the conditions of maximum (top) speed The electromotive power output of motor and the output mechanical power of diesel engine match, output voltage and load system match.Specifically set Meter requires as follows: can guarantee the output of maximum demanded power, and diesel engine speed under the conditions of diesel engine highest working speed It can be adjusted between idling and maximum (top) speed, the power output of diesel engine is made not only to be able to satisfy trailer system pair under different operating conditions In the demand of power, and reasonable revolving speed can be kept according to diesel engine demanded power output, be maintained at diesel engine and most preferably fire On oily characteristic curve, energy-saving effect is improved;Main generator selects magneto alternator, under the conditions of diesel engine highest working speed The power for dragging main generator output is maximum, meets the maximum power requirement of work business railcar alternating current traction system, different rotating speeds Under the conditions of main generator electromotive power output match with diesel engine output mechanical power;The real-time output power of specific main generator Size is then determined according to the demand of trailer system, in the power bracket set, main generator output power size with lead The power demand dynamic for drawing system is adaptive.
The beneficial effects of the present invention are: core of the invention is that selection magneto alternator replaces electrical excitation synchronous generator Machine, rotor structure is simpler, simplifies the structure of alternating current drive work business railcar diesel generator group, alleviates weight Amount, reduces the space occupied, improves reliability;Rotor of permanent-magnetic power generator is permanent-magnet material, is generated heat small, convenient for generator Cooling Design;Using magneto alternator, it is convenient to omit excitation unit omits field power supply, reduces cost;In addition, using Magneto alternator avoids the over-voltage phenomenon that electric excitation generator is also easy to produce.
