Detailed description of the invention
Below in conjunction with accompanying drawing, for HXD3/C type electric locomotive, the present invention is described in detail.
HXD3/C type electric locomotive, with accumulator for power supply, drives traction electric machine to rotate by main convertor (CI), produces pull strength, and on the circuit without 25KV contact net or in locomotive inspection and repair storehouse, low speed self is walked, locomotive inspection and repair storehouse of shunting for short distance and come in and go out.
1, the acquisition of DC600V voltage
HXD3/C type electric locomotive controls loop equipped with accumulator (capacity 170AH), and when locomotive normal operation, accumulator is in charged state, after bow drops in locomotive, stores electric energy in accumulator, and voltage is DC96V.Utilize high frequency switch power ,-inversion-rectification that storage batteries D C96V is boosted, it is thus achieved that DC600V power supply.
2, the driving of traction electric machine and locomotive speed control
HXD3/C type electric locomotive main converter (CI) is provided with position, storehouse, and main convertor (CI) is when position, storehouse works, and medium voltage is DC600V, and locomotive running gear speed is 1KM/H constant speed.DC600V voltage being connected to main convertor (CI) medium voltage, in position, storehouse, the 2nd or the 5th traction electric machine can be driven to rotate, locomotive is with 1KM/H constant speed traveling.
3, technical essential
(1) it will be seen from figure 1 that the DC600V running voltage of main convertor (CI) obtains in system, by main convertor inversion, drive traction electric machine, and minimum voltage is not less than DC350V.In order to control the output voltage of system within the scope of DC600V-DC350V, internal system is equipped with voltage/current measurement links.
From the specific curves of Fig. 2, when exporting electric current less than 30A, output voltage range is DC600V-DC350V, and to meet main convertor work, now, system works in restricted zone, and can be automatically stopped voltage output, to protect accumulator.
(2) output voltage given technology slowly
When system works, need to before main convertor (CI) works, afterflow electric capacity to main convertor (CI) is pre-charged, if first given 600V voltage, when the serious power shortage of afterflow electric capacity of main convertor (CI) or main convertor (CI) insulate low, very big dash current can be produced, cause the system failure or accumulator transient discharge.The present invention reuses voltage given technology slowly, and output voltage is slowly increased to 600V from 0V, it is therefore prevented that the generation of dash current.Meanwhile, when starting after the afterflow electric capacity charging of main convertor (CI), being also adopted by the slow given technology of output, traction electric machine will not produce very big electric current at the rotation initial stage.
(3) single-chip computer control system output is used
The present invention uses Single-chip Controlling DC600V output and LED chinese disply, has good man machine interface and safeguard protection.
The major function of design has:
A, DC600V output logic controls；
B, LED chinese disply.
Result of performance test and real train test, electric locomotive unit state of the present invention is good, dependable performance, steady quality.The application of the technological means such as, output voltage slowly given, Single-chip Controlling mild by Current limited Control, increases stability and the processing safety of output, has good man machine interface.
