Recently, GCD-1000HJ hybrid rail car was launched in Delingha Public Works section of Qinghai Tibet Group Corporation!
In response to the national policy of energy conservation and emission reduction, and to solve the problem of exhaust gas and noise pollution in the construction of Guanjiao tunnel of Qinghai Tibet Group Corporation, Baoji CRRC times and Qinghai Tibet Group Corporation jointly carried out the project of "Research on key technology of large road maintenance machinery development of Hybrid Electric rail car".
The successful development of the vehicle fills in the blank of hybrid technology in the field of track engineering machinery, lays a good foundation for the development direction of "high speed, high efficiency, green energy saving" of track engineering machinery, and lays a foundation for the subsequent development of track engineering equipment suitable for Sichuan Tibet Railway in extreme environment!
Advantages of hybrid rail car:
1. It can realize zero emission of tail gas in tunnel operation, and solve the problem of harm of tail gas emission and noise pollution to operators;
2. Hybrid traction is adopted to compensate the traction power by power battery to solve the problem of power reduction of high altitude diesel engine;
3. Resistance braking is adopted to realize constant speed downhill, reduce the stroke adjustment of brake cylinder and the frequency of brake shoe replacement, and reduce the labor intensity of daily maintenance;
4. Regenerative braking is used for downhill to charge the power battery and realize energy recovery.
