China's high-temperature superconducting application technology has made major technological breakthroughs in China. Yesterday, China's first mega-watt high-temperature superconducting electric motor successfully developed by the China Shipbuilding Industry Corporation 712 Institute was approved by the Ministry of Science and Technology in Beijing. This indicates that China has already possessed the megawatt high-temperature superconducting motor design and manufacturing capabilities, and it has become one of the few countries in the world that has mastered the key technologies of high-temperature superconducting machines. Under normal circumstances, when the electrons move in the metal, energy loss occurs, that is, there is resistance. In the superconducting state, electrons can move without flaws. High temperature superconductivity refers to the material at a relatively high critical temperature and the resistance drops to zero. In the 1980s, high-temperature superconducting technology achieved a "zero" breakthrough. Since then, the United States, Germany and other countries have invested heavily in research and development of high-temperature superconducting electric motors, and have successfully developed at the beginning of this century. As the first company engaged in the research of superconducting electric machines in China, since 2008, 712 Research Institute has undertaken the development of the “1000KW high temperature superconducting electric motor†as a key project of the 863 Program of the Ministry of Science and Technology. In July this year, the project passed the technical acceptance of the Ministry of Science and Technology and passed the Ministry of Science and Technology yesterday. Project Acceptance. The volume of the high-temperature superconducting motor is only 1/2 that of an ordinary motor, its weight is only 1/3, and the noise is much less. With the use of high-temperature superconducting motors, ships can save space, reduce size, reduce weight, reduce fuel consumption, increase endurance, durability, and stealth capabilities. High-temperature superconductor is mainly used in the field of shipbuilding and wind power generation and has significant social and economic benefits. “Mw-level high-temperature superconducting electric motor is the key to the marketization of high-temperature superconducting electric motors.†The person in charge of 712 said that the breakthrough of the key technologies of high-temperature superconducting electric motors is of great significance and will greatly promote the practical application of superconducting electric machines in China. process.
