The SS3B fixed heavy-duty electric locomotive is a 12-axle freight electric locomotive. It consists of two identical 6-axle locomotives connected by a coupler and a windshield. The two sections are equipped with electrical system high-voltage connectors, control cables, and network shielding. Line and air system control ducts. The entire vehicle can be controlled synchronously from any cab. The locomotive adopts single-phase power frequency system, voltage 25kV, AC-DC transmission, and the maximum operating speed of the locomotive is 100km/h.
Product Details
1. The locomotive has a continuous power of 9600kW, two sections, and 2 (Co-Co) bogies. Wheel circumferential resistance braking power is 8000kW.
2. Adopt thyristor unequal three-section bridge half-controlled voltage regulation control, and the front and rear bogies are independently powered.
3. The use of feed-in resistor braking expands the maximum constant braking power range of the locomotive in the low-speed zone.
4. The use of network technology improves the technical content of the locomotive's control system, increases the locomotive's reliability, and thereby reduces the locomotive's failure rate.
5. The locomotive adopts anti-idling, anti-sliding protection devices and electrical axle weight compensation technologies to improve the locomotive's adhesion utilization, which improves the locomotive's operating performance.
6. The constant current and quasi-constant speed characteristic control method is adopted to fully utilize the starting traction force of the locomotive and facilitate the operation of the driver and passengers.
