SS6B Electric Locomotive

Key technologies

1.The vehicle body adopts an integral load-bearing structure, double-end cab, large roof structure, large-area ventilation shutters and other traditional mature technologies.

2.The Co bogie and low-position horizontal traction rod device are used, which have high adhesion performance.

3.The main circuit adopts independent power supply from the bogie, which can be used for locomotive electrical axle weight transfer compensation and improve the adhesion utilization of the locomotive.

4.A power factor compensation device is installed on the main circuit side of the locomotive, so that the locomotive has a higher power factor and smaller harmonic interference current.

5.The electric drive system adopts a standardized asymmetric three-sec tion half-controlled bridge rectifier circuit, implements phase-controlled voltage regulation, and realizes the traction speed regulation characteristics of constant current quasi-constant speed control.

6.The brake system is an improved version of the DK-1 electro-pneumatic brake, with electro-pneumatic braking and air-electric combined braking functions.
