"Made in China" and then break through: Shenzhou independently developed traction system to create a number of domestic leading

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

In order to enhance the competitiveness of the rail transit national industry, Shenzhen Yingweiteng Transportation Technology Co., Ltd. has developed an autonomous rail transit vehicle traction system, and was held in Guangzhou on December 26th in the China Urban Rail Transit Association Technical Equipment Professional Committee. The “Autonomous Railway Vehicle Traction System Passenger Operation Assessment Review Meeting” and the “Shenzhen Yingwei Teng Urban Rail Vehicle Traction System Technical Level and Integration Capability Review Meeting” held in Shenzhen on December 27 successfully passed the assessment, marking the independence of Shenzhen Yingwei Teng The traction system of rail transit vehicles will officially enter the stage of promotion and application.

It is reported that the judging meeting has convened a rigorous review by more than ten leaders and experts from all over the country. The meeting was hosted by the China Urban Rail Transit Association and led by experts and experts from urban metro companies such as Beijing, Shanghai, Guangzhou, Shenzhen, Nanjing and Suzhou. Experts from major vehicle suppliers participate in the review.

Breaking technical barriers and enhancing domestic competitiveness

The 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 is always difficult due to technical difficulties, wide technical fields involved, large investment in research and development, and long cycle. The weak link of China's rail transit equipment manufacturing technology

For a long time, foreign joint ventures or cooperative enterprises have become the main suppliers of traction systems in China. The supply cycle is long, the service is slow, and the efficiency is low. Only 100% of the fully autonomous traction system companies are CRRC Group

On the other hand, 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. At present, China's traction system can not fully meet China's growing rail transit construction needs in terms of technical capabilities, competitive landscape and service level.

Since 2010, Shenzhen Yingweiteng Traffic Technology Co., Ltd. has started the R&D and manufacturing of rail vehicle traction system according to the national industrial policy guidance. Under the cooperation and support of Guangzhou Metro Group Co., Ltd. and CZ Zhuzhou Electric Locomotive Co., Ltd. After several decades of technical research by dozens of engineers, Yingweiteng traction system has taken the lead in domestic traction motor control and harmonic elimination. The technology has reached the international advanced domestic leading level and became the first and only in China. A product that has passed safety certification.

After the review, Shenzhen Yingweiteng Transportation Technology Co., Ltd. obtained the bidding qualification, can participate in project bidding at home and abroad, promote orderly and healthy competition in the domestic subway industry, further increase the localization rate, and achieve the ultimate goal of reducing construction cost and improving service level. .

37 intellectual property achievements are the only in China

The research and development of Shenzhen Yingweiteng Transportation Technology Co., Ltd. lasted for 60 months, breaking through the core technical difficulties of related systems and equipment, mastering system design, traction drive vector control, auxiliary power supply, traction motor, large power electronic power module design and structure. Key technologies such as design, heat dissipation design and EMC design, and successfully completed ground bench test, loading and unloading operation test, line operation test, and 50,000 km passenger operation assessment test.

At the same time, the company has experienced and passed 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 China Urban Rail Transit Association Technical Equipment Professional Committee. .

Yingweiteng traction system has obtained the “Safety Assessment Certificate” issued by China Railway Certification Center and EN15085 international welding design certification, becoming the first enterprise in China to pass the safety certification traction system, and accumulated more than 50 intellectual property rights in the research and development process, among which There are 37 authorized.

Wang Wei, Secretary-General of the Technical Equipment Professional Committee of China Urban Rail Transit Association, said at the judging panel that Yingweiteng Transportation Technology Co., Ltd., as the first and only supplier of traction system for rail transit vehicles with independent research and development capabilities, is the only one outside China CRRC Group. It is also the first and only private joint-stock enterprise in the core technology field of independent rail transit, and will become the first core system equipment manufacturing enterprise of the technology-original rail transit high-end equipment manufacturing industry in Shenzhen and even Guangdong Province.

In the future, 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 and enrich the regional industrial structure. Drive and promote regional economic development.
