Description
Technical field
The present invention relates to locomotive and motor-car technical field, particularly a kind of electric power system for diesel locomotive and diesel rail motor car.
Background technology
In train field, usually taked following two kinds of measures to be that diesel locomotive and diesel rail motor car are powered in the past:
1, diesel powerplant constant rotational speed running.This measure has two shortcomings: add fuel oil consumption, reduces the economy that train uses; Whole power system operational continuous firing, at high rotating speed, reduces the reliability of system, improves maintenance cost.
Auxiliary power supply generator set set up by 2 locomotives.This measure has two shortcomings: diesel generator set set up by locomotive, improves the difficulty of locomotive general layout, makes locomotive system complicated; Main pulling electric generator group and auxiliary power supply generator set are separate system, and can not complement each other for the power of locomotive traction and the power of auxiliary power supply, the degree of utilization of whole system is lower, and economy is poor.
Summary of the invention
Goal of the invention of the present invention is: for above-mentioned Problems existing, provides a kind of electric power system for diesel locomotive and diesel rail motor car.
The technical solution used in the present invention is such: a kind of electric power system for diesel locomotive and diesel rail motor car, comprise three phase alternator group, rheostatic brake device, filter respectively a set of, high-voltage rectifying device, rheostatic brake current transformer, AuCT and traction convertor be two covers respectively.
The three plase alternating current that described three phase alternator group produces divides two-way; Each road is rectified into stable direct current through high-voltage rectifying device and high-voltage capacitor respectively, more successively by rheostatic brake current transformer, AuCT, traction convertor, finally drives phase asynchronous traction electric machine.
Between described high-voltage rectifying device and AuCT, rheostatic brake current transformer is also set; Two rheostatic brake current transformers are connected with rheostatic brake device jointly, and the outgoing current of two AuCTs is also jointly connected to filter and carries out filtering process, is then exported by supply transformer.AuCT converts the HVDC after high-voltage capacitor rectification to frequency and voltage constant power supply, and the quality of power supply is improved by filter.
As optimal way, high pressure three phase switch is set between described AuCT and filter.After such setting, the disconnection that can control this road of filter easily still closes.
As optimal way, described supply transformer exports AC-HEP, AC220V, AC-aux, and supply transformer also exports DC-aux, DC24V respectively by electric power conversion apparatus.
AC-HEP three plase alternating current provides power for passenger train, AC220V alternating current provides miniwatt household electricity for locomotive, the power supply that AC-aux three plase alternating current provides frequency and voltage constant for locomotive assisting system, DC-aux, DC24V provide power for locomotive storage batteries charging, DC machine, illumination, electric component, microprocessor control system, diesel engine control system.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows: simplify locomotive system, improve locomotive reliability; In same system, can be locomotive assisting system by same generator set, power supply system of train, locomotive traction system power, its energy can supplement mutually; Also can make full use of rheostatic brake energy, improve the economy of the operation of whole train, reduce the operation cost of user.
