Electric motor car, the "national business card" that has emerged in the past 20 years
20 years ago, on September 27, 1999, a blue and white train, which looks like a shark, set off from Guangzhou and headed for Shenzhen. This is the first generation of high-speed railway EMU "great white shark" in China, and also the first domestic commercial train with a speed of 200 kilometers per hour. In the past 20 years, starting from "great white shark", China's electric multiple units have started to pursue their dreams at high speed: with the birth of "Blue Arrow" and other electric multiple units, they have started to "start" in the era of high-speed railway; from "China Star" to "harmony", technology has been constantly updated; from "China standard multiple units" R & D to "Renaissance" series, products have been produced. From wheel and rail to maglev, China is constantly pushing the world railway technology to "dream" faster, stronger and better.
in the past "golden week of National Day", more than 100 million passengers were sent by the national railway transportation. On October 6, the peak time, more than 15 million passengers were sent by the railway on that day, which is only available in China in the world.
electric power car, the shining "business card of mobile country", changes life, changes China, goes abroad and leads the world! From scratch,
"celebrates with tears" every time it succeeds. Located in the hinterland of Hunan Province,
Zhuzhou is the largest R & D and manufacturing base of China's rail transit, with a global market share of electric locomotives of more than 20%, ranking first in the world. The interview of
reporter started from Zhuzhou, Hunan Province, the cradle of China's EMUs, and now the "China Power Valley". The footprints extended to Beijing, Tianjin, Hebei, Chengdu, Changchun and other places. From the narration of generations of advanced rail transit equipment entrepreneurs and developers, we can explore the wind and rain course of the birth of China's EMUs. In the story of the development of China's advanced rail transit equipment, there is a widespread saying: in the early stage, a certain type of electric locomotive was able to solve the major technical bottleneck by bringing back a kind of spare parts from abroad.
the above-mentioned statements are totally out of the blue in the eyes of the old experts in the field of China's advanced electric locomotive development, such as Ke Yinuo and Gao Peiqing. A 6031 a 6031 "how can parts that are more than one meter long, tens of centimeters in diameter and weigh more than one hundred jin be packed in the returned luggage?" Gao Peiqing said that China's development of advanced electric locomotives and railcars mainly depends on self-reliance, innovation and hard work. A 6031 a 6031 "we all have a belief in the research of electric locomotives: If foreigners can make them, Chinese people will make them; if foreigners can't, Chinese people will make them!" Said coeno. In the 1990s, the development of high-speed railway transportation was incorporated into the national strategic plan, and the development of EMUs began at that time. In June 1998, the former Ministry of Railways organized a high-speed test in Xuchang xiaoshangqiao section of Beijing Guangzhou railway. After the transformation of transmission ratio and pneumatic layout of SS8 electric locomotive made in China, the train made in China has run 240 kilometers per hour for the first time in the test. An authoritative expert of
said that hundreds of millions of experimental data have been collected in this test, which has accumulated a certain foundation for the later development of EMUs and strengthened the confidence of developing high-speed trains in China.
in the Ninth Five Year Plan of China, the electric multiple unit with a speed of 200 km / h has been officially approved.
in May 1999, the power centralized EMU "great white shark" was successfully trial manufactured in Zhuzhou. Since then, in the online test of the first quasi high-speed railway in China - Guangzhou Shenzhen intercity railway, 223.2 km / h of instantaneous speed has been achieved. This is close to the current definition of "high-speed Railway"! At that time, the highest speed of Chinese railway passenger cars was generally less than 100 kilometers per hour.
on September 27, 1999, the "great white shark" was officially put into trial operation on Guangzhou Shenzhen railway, marking China's entry into the era of quasi high speed railway transportation.
"'Great white shark 'offline, ex factory, trial operation... Every key node has good news, and we all applaud and celebrate with tears! " In Zhuzhou, many interviewed experts look back and are filled with emotion. Along with the market-oriented reform of railway, the development of EMUs in China has been on the upsurge. "Blue Arrow", "star of Central Plains", "star of China"... A number of domestic EMUs have come off the production line, and China has gradually formed the ability to independently develop EMUs with a speed of 200-300 km / h.
in September 2001, the "star of Central Plains" power decentralized EMU was offline, and then put into operation in Zhengzhou Wuchang line; in 2001, the power centralized EMU "star of China" began to be developed, and ran 321.5 km / h in the sprint test in November 2002, and the Chinese train first crossed the threshold of 300 km / h! After a series of scientific and technological breakthroughs and commercial operation, the technology and products in the field of electric power car in China have achieved a historic breakthrough from scratch. According to experts such as Zhu Xiaoning, Professor of Beijing Jiaotong University, and Dai Guangze, Professor of Southwest Jiaotong University, EMUs in China have experienced the "whole process test" from R & D, manufacturing to operation since "great white shark" and "Blue Arrow". The preliminary preparation of
has cultivated a large number of talents and laid a solid foundation for the rapid development of China's advanced rail transit equipment. A 6031 a 6031 from have to you a 6031 a 6031 car create "change China" miracle a 6031 a 6031 innovation is never behind closed doors! China's EMU development and progress has always been in an inclusive and open mind, cherishing every opportunity brought by reform and opening up to carry out technical exchanges, learn from each other and learn from each other. Since 2004, along the road of "introduction, digestion, absorption and re innovation", China's EMUs have entered the stage of "bigger and stronger" with faster speed and better technology. On August 1, 2008, Beijing Tianjin Intercity Railway, the first high-speed railway with a design speed of 350 kilometers per hour, was put into operation, and China officially entered the "High-speed Railway Society". The chain reaction of
independent innovation and open integration is triggered. In 2010, crh380a EMU independently developed by China was offline in Qingdao, with an operating speed of 350 km / h and a maximum speed of 380 km / h or above.
in 2012, the research and development of China's standard EMUs was started, and on July 15, 2016, the world's new record of high-speed rail train intersection speed was set at a speed of more than 420 km / h. On June 25, 2017, China's standard EMU was officially named "Fuxing". It was officially launched in both directions on the Beijing Shanghai high speed railway, that is, the Beijing Shanghai high speed railway resumed 350 kilometers per hour.
reporter learned from CRRC Changchun rail car Co., Ltd. and other enterprises that the overall design of "Fuxing" and key technologies such as car body, bogie, traction, braking and network are all independently researched and developed in China, with completely independent intellectual property rights, and the Chinese standard accounts for 84%. This is the world's fastest running high-speed rail train, which has reached the world's advanced level and is the "King" of China's EMUs.
from CRH1, CRH2, CRH3 and CRH5 introduced in the early stage to crh380 series and "Fuxing" series independently developed in the later stage, China has the most diverse and complete EMUs in the world, covering various speed classes of 200-350 km / h. At present, China's high-speed rail business mileage ranks first in the world. The self-developed series of high-speed EMUs have been put into operation for 11 years, and the safety and reliability of the whole system have been fully verified. Taking vehicles as an example, the world's general safety standard is that there are no more than two failures per million kilometers of operation of high-speed EMUs, and the average failure rate of China's EMUs is less than 0.43 per million kilometers.
"China has mastered the core technology of high-speed rail, and has multiple advantages such as low cost, strong delivery capacity and rich operation experience. The overall level is in the forefront of the world." Liu Youmei, academician of the Chinese Academy of engineering, said. As of the end of 2018, the business mileage of China's railway has reached 131000 km, of which 29000 km is high-speed railway, accounting for more than 60% of the world's total high-speed railway. Since 2008, China's high-speed rail has transported more than 10 billion passengers. At the same time of serving the economic and social development, the huge "application scenario" makes China's bullet trains have a development environment that no other country in the world can match. The "virtuous circle" formed by the interaction between technology and market makes China's bullet trains keep moving forward.
, from nothing to have, from having to being excellent, from catching up to leading, Chinese EMUs represented by high-speed rail, with the innovative spirit of self-reliance and embracing the world's vision, subverted the old image of made in China, and performed the "high-speed rail miracle" of later development and surpassing. A 6031 a 6031 high speed railway, change life; high speed railway, change China! This is the common feeling of 1.4 billion Chinese. A 6031 a 6031 leads the future a 6031 a 6031 journey of "pursuing dreams and fulfilling dreams". A 6031 a 6031 day ago, China's first EMU exported to the European Union, the Sirius Star, arrived in the Czech Republic. EU has strict requirements and access threshold for train quality and reliability. The export of Sirius means that China's EMUs have been recognized by the high-end market of global rail transit equipment.
in Malaysia, the ETS EMU exported by China runs 176km out of the highest speed of meter gauge railway in the world, just like "Dancing" on the balance beam; in Macedonia, the EMU exported by China has obtained the European Union's technical specification for railway interconnection (TSI) certification; in Indonesia, 11 EMUs with 350km / h China's high-speed EMUs are about to fly Yawan high speed railway... In addition to going to the world, China continues to make breakthroughs in the technology, products and services of EMUs, seizing the new trend of green and intelligent, so as to take the lead in the world industrial competition in the future.
has experienced "direct current" and "alternating current", and the traction technology of rail transit vehicles in the world is developing towards the "permanent magnet" drive technology of version 3.0. On the eve of national day, CRRC Zhuzhou Motor Co., Ltd. released the tq-800 permanent magnet synchronous traction motor for 400 km / h high-speed EMU, which paves the way for China's EMU traction transmission technology to "permanent magnet era" with higher power density, higher efficiency and lower life cycle cost.
in December 2018, cr200j train with a speed of 160km / h joined the "Fuxing" family, refreshing the height of China's ordinary speed railway with the quality of "Hulk" EMU. A 6031 a 6031 from Ha Mu high speed railway in the extremely cold area of - 40 ℃ to the Lanxin high speed railway with the highest wind speed of 60 meters per second in the passing area, China's high-speed railway trains are speeding in the grasslands, snowfields, plateaus, deserts and Gobi
