CZ Zhuzhou Electric creates a “high-speed rail” industrial chain

The traction motor is the heart of the high-speed rail EMU and is the source of power for the train. On the 11th, the reporter learned from CRRC Zhuzhou Motor Co., Ltd. that the Chinese standard EMU, which is equipped with the core power developed by the company, traction motor and traction transformer, has basically completed the first round of type test test of the 60,000-kilometer vehicle. It is planned to be completed by the end of this year. 600,000 km of vehicle line assessment.

According to the test results, the technical indicators of the traction motor and the traction transformer all meet the design requirements, and are quite stable and excellent. This means that China's high-speed rail drive technology with its own independent intellectual property rights has its own standards. From steam locomotives to the world's largest high-speed rail network, from the introduction, digestion, absorption to the completely independent innovation of China's "standard", the high-speed rail dream is a true portrayal of the Chinese dream.

Nearly 500 national patent grants, 36 National Science and Technology Progress Awards, China Railway Society and provincial and municipal group-level scientific and technological progress awards, more than 40 Hunan scientific and technological achievements appraisal... As the core power of China's high-speed rail, While establishing a high-end power brand with numerous scientific research and innovation achievements, CZ Zhuzhou Motor is promoting the rapid development of four major industrial sectors such as rail transit, wind power generation, high-efficiency motors and special transformers in accordance with the "high-speed rail quality".

In October 2015, the TQ-600 permanent magnet synchronous traction motor developed by the company passed the test of the first-round line operation test of the first permanent magnet high-speed railway in China. This "high-end artifact", which is known as the 3.0 version of high-speed rail power, has made China one of the few countries in the world to master the "permanent magnet high-speed rail" traction technology, and established the company's leader in the world's rail transit equipment traction dynamics. status.

According to the technicians, this traction motor is 35% lighter than the traction motor of the existing high-speed EMU, while the efficiency is improved by more than 3% and the energy saving is over 10%. A series of 8 high-speed trains will be used to calculate the Beijing-Shanghai line every day. After loading the "tip artifact", it can save more than 1 million kilowatt-hours a year.

CZ Zhuzhou Motor also applied the core technology of cutting-edge rail transportation accumulated in the past 60 years to the development of wind turbines. At present, more than 10,000 wind turbines have been delivered at home and abroad, and the output of clean energy is nearly 8 billion kWh. At the end of July 2015, the 5MW offshore wind turbine developed by the company for the German company was off the assembly line. This is the first time that China's megawatt wind turbines have entered the EU market where the quality requirements for industrial products are “rigorous”. In order to win the order, CZ Zhuzhou Motor completed the submission of more than 100 documents and obtained the quality standard VDA quality assessment in the EU quality system. At present, there are only a handful of domestic companies that have passed the VDA review.

In response to the call for national energy conservation and emission reduction, CZ Zhuzhou Motor has successively established a number of high-efficiency and energy-saving motor product technology platforms such as oil drilling rigs, mining machinery, pure electric buses, shield machines and steam compressors. Developed the first 750kW and 500kW asynchronous variable frequency motor in Asia's first power-distributed high-speed finishing line, filling the domestic gap.

In the field of special transformers, an industrial platform for epoxy cast dry-type transformers has been established, in which the core technology of self-contained filler casting is in the leading position in the industry. At the same time, it successfully developed the first balanced power supply converter device in China and put it into use, and provided the core power and traction rectifier transformer for China's first medium and low speed maglev railway, Changsha Maglev Express.

Xiao Anhua, general manager of CZ Zhuzhou Motor Co., Ltd. said that the company's core competitiveness is due to its technology and research capabilities have always been at the forefront of the industry and the times. In order to ensure the leading position of product research and development capabilities, the company has increased its investment in science and technology, and has a state-of-the-art test platform such as a national motor test room, a transformer test room and an insulation test room, which greatly enhances the research and development capabilities and verification methods of new products. Two months ago, it also invested nearly 300 million yuan to start the construction research institute and engineering research center, and successfully incorporated into the first batch of “producing strong provincial projects” in Hunan Province. At the same time, the Ministry of Technology Research was established to conduct forward-looking research on cutting-edge technologies in the industry.

"We will give full play to the leading edge of rail transit traction technology, and extend the core capabilities of R&D, technology, manufacturing and management with 'high-speed rail quality' to the entire high-end power industry chain such as wind power generation, energy-efficient and special transformers. The first brand of high-end power in China.” Xiao Anhua said.
