Detailed description of the invention
Below in conjunction with accompanying drawing, for the electric locomotive of HXD3/C type, the present invention is described in detail.
The electric locomotive of HXD3/C type take storage battery as power supply, drives traction electric machine to rotate by main convertor (CI), and produce tractive force, on the circuit without 25KV contact system or in locomotive inspection and repair storehouse, low speed self is walked, locomotive inspection and repair storehouse of shunting for short range and come in and go out.
1, the acquisition of DC600V voltage
HXD3/C type electric locomotive control loop is equipped with storage battery (capacity 170AH), and when locomotive normally works, storage battery is in charge condition, after bow falls in locomotive, stores electric energy in storage battery, and voltage is DC96V.Utilize high frequency switch power, storage batteries D C96V is boosted-inversion-rectification, obtain 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 is connected to main convertor (CI) medium voltage, in position, storehouse, the 2nd or the 5th traction electric machine can be driven to rotate, and locomotive is with the traveling of 1KM/H constant speed.
3, technical essential
(1) as can be seen from Figure 1, the DC600V operating 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 the output voltage of control system is within the scope of DC600V-DC350V, internal system is equipped with voltage/current measurement links.
From the specific curves of Fig. 2, when outgoing current is less than 30A, output voltage range is DC600V-DC350V, and to meet main convertor work, now, system works in restricted zone, and can automatically stop voltage exporting, to protect storage battery.
(2) the slow given technology of output voltage
When system works, need before main convertor (CI) work, afterflow electric capacity to main convertor (CI) carries out precharge, 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 large rush current can be produced, cause the system failure or storage battery transient discharge.The present invention reuses the slow given technology of voltage, and output voltage is slowly increased to 600V from 0V, prevents the generation of rush current.Meanwhile, when starting after the afterflow capacitor charging of main convertor (CI), also adopt and export slow given technology, traction electric machine can not produce very big current at the rotation initial stage.
(3) single-chip computer control system is used to export
The present invention uses Single-chip Controlling DC600V output and LED chinese disply, has good man-machine interface and safety guard-safeguard.
The radical 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, output voltage mild by the current limit control technological means such as given, Single-chip Controlling slowly, increases the stability and processing safety that export, has good man-machine interface.
