DJ2 AC drive passenger electric locomotive
 

As the first commercial alternating current drive passenger fransport electric locomotive that poses the intellectual asset in the history of China,DJ2 is primarily employed for passenger transporting tranction on the main line and high-speed traction on the special line.It can cover generic speed, quasi-high-speed and high speed lines. DJ2 is in the possession of the following predominances such as super coherence, large continuous power range, high shaft power, high efficiency and power factor, small harmonic interfere, low maitenance rate, small energy consuming and good run performance.



Distinctive features of DJ2

Versatility for different electrified line
High efficiency and small energy consuming
Weak communication interfere because of compatibility of high electromagnetism
Workable in different severe environment Green traction power
Modular structures, convenient for maintenance and change
GTO water-cooled central convertor andADA drive system
Method of speed Regulation;bogie control
Water-oiled complex cooler,heat abstraction of 250KW

 

Apperance of the locomotive and interior decoration of driver's cab

Quasi-streamliner,good-sized interlayer top cover and trunk groundframe compose the car body of lightweighting unitarily load bearing framework,which not only meets the requirement of integration and modularization of the equipment,but ensure the modularization of body design in terms of enough strength condition.The apperance of the locomotive upgrade that of the locomotives.Thus it can give a strong visual impact and a rich time style as well.The operating console is arranged in compartment style,the driver's cab is designed in according to both manual and machine control,the pull-and-push master controller tallies with people's operating practice,the rearview mirror plays an important roal for the rear operating watch of the locomotive,and the chair can be adjusted to the satisfactory height freely.Together with the cabinet-type air conditioner and warm-air heater,these homely advanced devices make the cab a comfortable working environment.

 

Three key components

¡ñ The convertor ¡ñ Computer controll device,applied through distributed cabinet computer controll system,is made up of several modules and they are connected by a main line to form a net. ¡ñ Each locomotive is installed with four three-phase quadrupole squirrel cage asynchronous motors,and they are cooled by forced ventilation.
