"Blue Arrow", a high speed AC drive electric passenger
train set of a new generation, is developed and manufactured
by Zhuzhou Electric Locomotive Works, Zhouzhou Electric Locomotive
Research Institute, Changchun Car Co., Ltd and Guangzhou Railway
Group jointly in 2000 to meet the mass transit requirement
of "Small formation, high density and high speed".
Electric transmission system of the locomotive adopts advanced
IPM water cooling unit, asynchronous traction motor of 1225kW
and microcomputer network control system in distribution type.
Circuit design introduces modularized structure to achieve
continuous performance of EMU after cutting off the failure
part.
Regarding control system, two-stage train communication network
is used: MVB for connection of interior equipment in the car
and WTB for connection between different cars can implement
multiple-unit coupling of two trains. Redundancy design (master
loco preheated and redundancy input and output) is employed
for control system to achieve higher reliability.
Regarding bogie, web type mono-block wheel, hollow shaft
and traction motor semi-suspension structure are adopted.
Furthermore, two-stage six-connecting-rod wheel set hollow
shaft drive gear and post-positioned middle pull-push low
flat traction rod are used. Axle disk brake device is employed
for foundation brake, which has the function of ABS anti-slip.
Brake is of DK-1B type, which has the function of pneumatic-electric
blend brake and train E-P brake and the function of automatic
service brake cooperation with safety device as well.
