Accompanying drawing explanation
The electric locomotive of Fig. 1 the utility model is from the fundamental diagram of the storage battery of running gear.
The electric locomotive of Fig. 2 the utility model is from the working curve diagram of running gear.
The electric locomotive of Fig. 3 the utility model is from the principle of work block diagram of running gear.
The specific embodiment
Below in conjunction with accompanying drawing, the HXD3/C type electric locomotive of take is elaborated to the utility model as example.
The electric locomotive of HXD3/C type be take storage battery as power supply, by main convertor (CI), drives traction electric machine to rotate, and produces tractive force, and on the circuit without 25KV contact system or in locomotive inspection and repair storehouse, low speed self is walked, for the short range locomotive inspection and repair storehouse of shunting 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 works, storage battery is in charge condition, and locomotive falls after bow, stores electric energy in storage battery, and voltage is DC96V.Utilize high frequency switch power, to boost-inversion-rectification of storage batteries D C96V, obtain DC600V power supply.
2, the driving of traction electric machine and locomotive speed are controlled
HXD3/C type electric locomotive main converter (CI) is provided with storehouse and uses position, and when main convertor (CI) is worked with position in storehouse, 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 storehouse, with position, can drives the 2nd or the 5th traction electric machine rotation, locomotive is with the traveling of 1KM/H constant speed.
