[Explanation] On the evening of July 29, the Shen 24 electric locomotive jointly developed by CRRC Zhuzhou Electric Locomotive Co., Ltd. and the National Energy Group rolled off the assembly line in Zhuzhou, Hunan. The electric locomotive broke the world record for rail transit equipment with a single power of 28,800 kilowatts and a tractive force of 2,280 kilonewtons, becoming the world's largest electric locomotive.

  The reporter saw on the off-line site that the locomotive was composed of 6 sections, with a length of 106 meters, with a driver's cab set at both ends, and the interior of the locomotive was connected. The car was marked with a design speed of 120 kilometers per hour.

  According to Throne, the manager of the R&D Department of CRRC Locomotive Systems, unlike the previous electric locomotives with a single locomotive, two-carriage or three-carriage, the Shen24 electric locomotive pioneered adaptive configuration of the network side circuit and network dynamic grouping control technology, which can achieve 16 The flexible grouping of axles (4 sections), 20 axles (5 sections) and 24 axles (6 sections) meets the needs of various capacity, and only one crew is required.

  It does not simply mean that the power unit is put together. One is that the traction can be pulled, and the other is the braking. It is very important that I can stop. You can't say that my car can't stop. This is definitely unrealistic. Yes, so for the brake system, we adopt a new generation of modular, intelligent and distributed brakes.

  [Explanation] In addition, the locomotive is also equipped with a "smart brain" that can realize intelligent driving and intelligent operation and maintenance. It has functions such as automatic wake-up, automatic starting, automatic speed regulation, and automatic parking. It does not require manual manipulation during travel and is equipped with intelligence The operation and maintenance platform has constructed a life-cycle failure prediction and health management system to realize intelligent perception of locomotive status, intelligent identification of failures, automatic diagnosis of key components, and monitoring of deterioration operations.

  Talking about the difficulties encountered in the process of research and development, the throne said that apart from technical difficulties, the biggest impact is the epidemic.

  Because we are a OEM, we need many units to come out and cooperate. During the epidemic, this communication, including face-to-face exchanges, including some technical discussions, still encountered various problems during the period, and then we adopted various methods to increase Online (communication), including everyone working overtime to rush forward after the epidemic has eased.

  [Explanation] It is reported that after the delivery of the Shen 24 electric locomotive, it will run on the Shenshuo Railway of the National Energy Group to improve the transportation efficiency of China's energy transportation artery.
