The world's first technology × 3! my country's first new intelligent heavy-duty electric locomotive rolls off the assembly line

Release time:May 10, 2024 03:11 AM

The reporter learned from CRRC that my country’s first new intelligent heavy-duty electric locomotive officially rolled off the assembly line in Zhuzhou, Hunan Province on May 9, marking another major technological breakthrough in the field of heavy-duty railway transportation equipment in my country.

This eight-axle "steel giant" is currently the world's most powerful permanent magnet direct drive heavy-duty freight electric locomotive. The maximum traction power of a single locomotive can reach 10,400 kilowatts. Compared with traditional electric locomotives with the same number of coaxes, a single locomotive The single-trip transportation volume can be increased by nearly 1,200 tons, and the comprehensive annual transportation volume can be increased by nearly 280,000 tons.

According to reports, the locomotive has three world-first technologies. The locomotive uses the world's first high-power silicon carbide converter, which can adapt to more complex line and grid conditions and make the locomotive traction smoother. At the same time, this locomotive is also equipped with the world's first high-torque permanent magnet traction motor. Compared with existing motors, it can increase the wheelbase nearly six times, and can directly drive the bogie, making the transmission efficiency higher and more environmentally friendly.

In addition, the locomotive also uses the world's first high-traction direct-drive bogie for load-bearing, which is equivalent to adding a pair of flexible and powerful "legs" to the locomotive. The impact force between the wheel and rail is smaller during movement, and the dynamic performance is better.

After the locomotive rolls off the production line, it will be used for heavy-duty transportation on the Shuohuang Railway, the second largest coal transportation channel from the west to the east in my country, to help ensure energy supply.

But this story was soon replaced by his extravagant and corrupt behavior. The investigation found that there were over 400 bottles of famous liquor carefully stored in Yu Zhebin's cellar, all of which were sent by his subordinates and management service recipients. Not only that, when faced with red envelopes and gifts from subordinates, he takes all sizes,
