China's rail transit equipment traction system adds new

Rail transit equipment is one of the few industries in which China's equipment manufacturing industry has made major breakthroughs in its independent innovation. Its innovations have not only achieved import substitution, but also made China's manufacturing have “hard-gas” capital, and it is embracing the global market with unprecedented strength. . Domestic related companies are also benefiting from it, and INVT is one of them.

On December 27th, the rail transit vehicle traction system independently developed by Shenzhen Yingweiteng Transportation Technology Co., Ltd. (referred to as “Yingweiteng”) has passed the two assessments of passenger operation and integration capability. China rail transit equipment traction system supplier has added a private enterprise. The figure of the enterprise.

The judging panel convened more than ten industry experts from across the country for review. The leaders and experts from urban metro companies such as Beijing, Shanghai, Guangzhou, Shenzhen, Nanjing, Suzhou, and experts from major domestic rail transit vehicle manufacturers participated in the review.

Market pattern curing

Rail transit vehicle equipment belongs to the high-end equipment manufacturing field that is under development in China. It not only plays a vital role in social life as a public transport, but also relates to national security. Among them, the traction system as the electric drive vehicle power system is the core subsystem in the train system, and also the weak link of China's rail transit equipment manufacturing technology.

In recent years, rail transit equipment manufacturing technology has been vigorously developed with the support of national policies, but it presents the problem of uneven development in the segmentation field. Among them, the traction system has always been the weak link of China's rail transit equipment manufacturing technology due to its technical difficulties, wide technical fields, large investment in research and development, and long cycle.

For a long time, foreign joint ventures or cooperative enterprises have become the main suppliers of traction systems in China, but the supply cycle is long and the service response is slow. Due to the high technical barriers in the field of rail transit traction and control systems, most of our enterprises lack independent intellectual property rights. Therefore, they often bid together with foreign companies. The main companies in the market include Bombardier, Alstom, Siemens, Alcatel, Westinghouse, etc. . China's fully localized traction system manufacturers only have a few such as CRRC Group.

At the same time, China's rail transit vehicle market is in a period of rising development, and the demand is huge. It is spreading from first- and second-tier cities to third- and fourth-tier cities. According to the development plans of various cities in China, 6,200 kilometers of urban rails and subways will be built nationwide in 2020, and 11,700 kilometers will be built in 2050, accounting for more than half of the world's total mileage.

According to the industry data of China Urban Rail Transit Association and other industries, the annual average demand for traction and control systems (including spare parts and spare parts) of the national rail transit from 2015 to 2020 is about 10 billion yuan. In the next five years, the national rail transit traction and control system market will exceed 50 billion yuan.

On the one hand, there is a huge market demand. On the one hand, the technical capabilities, competition pattern and service capacity of China's traction system cannot fully meet China's growing rail transit construction needs. In order to break the monopoly of foreign capital and promote the development of domestic related industries, China has been encouraging and supporting the research and development of the orbital traction control system, and strive to achieve the localization of core technologies.

According to the national industrial policy orientation, Yingweiteng started the development of the traction system of rail transit vehicles in 2010. With the support of Guangzhou Metro Group Co., Ltd. and CZ Zhuzhou Electric Locomotive Co., Ltd., after more than five years of technical research, Yingweiteng has made breakthroughs in traction drive vector control and harmonic elimination, and has reached the international advanced domestic leading position in technology. Level, and become the first product in China to pass safety certification.

Multiple technology leadership

According to the relevant person in charge of Yingweiteng Company, the company has solved the core technical difficulties of related systems and equipment after 5 years of development, and mastered the system design, traction drive vector control, auxiliary power supply, traction motor, large power electronic power module design and structural design. Key technologies such as heat dissipation design and EMC design, and successfully completed the ground bench test, the loading and unloading operation test, the line operation test, and the 50,000-kilometre passenger operation assessment test. At the same time, the complete experience and passed the Chinese city. The entire process of technical program review, pre-loading review, pre-shipment review, passenger operation assessment, technical level and integration capability review conducted by the Technical Committee of Technical Support of the Rail Transit Association.

The relevant person in charge of the Technical Equipment Professional Committee of China Urban Rail Transit Association stated that the Invitro Traction System has successively obtained the “Safety Assessment Certificate” issued by China Railway Certification Center and the EN15085 International Welding Design Certification Certificate, and has become one of the few enterprises in China that has passed the safety certification traction system. More than 50 intellectual property rights have been accumulated in the R&D process, of which 37 have been authorized.

As a new rail vehicle traction system supplier with independent research and development capabilities, Yingweiteng is also a private enterprise in the core technology field of independent rail transit. It will become the first technology original in Shenzhen and even in Guangdong Province. Manufacturing enterprise of core system equipment for rail transit high-end equipment manufacturing industry.

After further application and development, Yingweiteng traction system can be applied to the fields of trams, intercity trains, electric locomotives, motor trains, high-speed trains, special road vehicles, electric drive ships, etc., to improve the domestic high-end equipment manufacturing level, enrich the regional industrial structure, and promote And promote regional economic development.

The relevant person in charge of the Technical Equipment Professional Committee of China Urban Rail Transit Association said that the approval of the traction system review of Yingweiteng Transportation Technology Co., Ltd. will further promote the further in-depth independent research and development of Yingweiteng in the relevant core technology fields, and accelerate the autonomy of the key core systems of China's rail transit. Process.

The reporter learned that after the approval, Shenzhen Yingweiteng Transportation Technology Co., Ltd. obtained the bidding qualification, can participate in the bidding of domestic and foreign projects, promote the orderly and healthy competition of the domestic metro industry, further increase the localization rate, and reduce the construction cost and improve the service. The ultimate goal of the level.
