Abstract
The utility model discloses an AC-DC-AC electrical transmission test device, which consists of a transformer, an AC-DC-AC transmission device, a DC motor, an AC motor, a motor unit connecting device and a chopper regulation controller, wherein the AC motor is connected with the output end of the AC-DC-AC transmission device through a three-phase cable, the DC motor is connected with the AC motor through the motor unit connecting device, one end of the chopper regulation controller is connected with the DC motor through a two-phase cable and the other end of the chopper regulation controller isconnected with the DC output part of the rectifying unit of the AC-DC-AC transmission device through a two-phase cable. Since the DC power generator, the excitation device and the resistor box of thetraditional test are abandoned, the utility model has the advantages that the power consumption during the test is reduced, the test device can be used to test both the DC motor and the AC motor, andthe power consumption is minimized.
Description
Technical field
The utility model relates to a kind of Electrified Transmission test unit, particularly a kind of friendship orthogonal Electrified Transmission test unit that is used for the electric locomotive test.
Background technology
At present along with the fast development of Power Electronic Technique, to hand over to direct transfer moving and hand over the application of orthogonal transmission very extensive, its test unit is also very perfect, and especially electric locomotive is produced employed friendship and is direct transferred moving and hand over the orthogonal transmission test device perfect especially.This class that shown in Figure 1 is exactly is handed over a kind of in orthogonal Electrified Transmission test unit, and it comprises transformer, hands over orthogonal gearing, direct current motor, AC motor, excitation unit and resistance box.But this class of generally using is at present handed over and is direct transferred the dynamic test device and hand over the orthogonal transmission test device, all is to utilize resistance box or water resistance as load, belongs to the test unit of pure energy-dissipating type, and is the big power consumer.At above-mentioned problems of the prior art, a kind of novel friendship orthogonal Electrified Transmission test unit of research and design overcomes that existing problem is very necessary in the prior art.
Summary of the invention
In order to solve problems of the prior art, the purpose of this utility model be to design a kind of not only can test AC motor, also can test direct current motor, simultaneously but do not use resistance box as load, can overcome the friendship orthogonal Electrified Transmission test unit of energy consumption problems of too.
To achieve these goals, the technical solution of the utility model is as follows: a kind of friendship orthogonal Electrified Transmission test unit comprises transformer, hand over the orthogonal gearing, direct current motor, AC motor, also comprise motor unit coupling arrangement and copped wave adjustment control, described transformer is connected with the input end of handing over the orthogonal gearing by threephase cable, described AC motor is connected with the output terminal of handing over the orthogonal gearing by threephase cable, described direct current motor is connected with AC motor by the motor unit coupling arrangement, and an end of described copped wave adjustment control is connected with direct current motor by two-phase cable, the other end is connected with rectification unit direct current output in handing over the orthogonal gearing by two-phase cable.
Motor unit coupling arrangement described in the utility model is a shaft coupling.
Copped wave adjustment control described in the utility model links to each other with a control desk that can carry out telecommunication network control by umbilical cable.
Compared with prior art, the utlity model has following beneficial effect:
1,, thereby reduced the energy consumption in the process of the test because the utility model has been cancelled Dyn., excitation unit and the resistance box of traditional experiment device.
2, after the alternating current of exporting owing to transformer of the present utility model is delivered to and handed over the orthogonal gearing, can directly drive AC motor and test; Can drive direct current motor behind the electric current process copped wave adjustment control by rectification unit output tests.Thereby realized that a test unit can test direct current motor and AC motor respectively.
3, because the utility model has adopted the direct current motor of mutual feedback mode with the AC electrical arbor axle to be connected, the load each other of two motors is in the generating state operation as the motor of load, and the feedback that can accomplish energy farthest reduces energy consumption.
4, because the utility model has increased remote console, can adopt the telecommunication network control mode, reduce the danger of test, improve the reliability of test.
5, the utility model can be conveniently used for realizing handing over direct transfer experimental study and the teaching moving and transmission of friendship orthogonal.
