The first high temperature superconducting electric levitation test system in China has completed its first suspension operation, with a maximum speed of more than 600km / h.

Thanks to CTOnews.com netizens pigeon for delivering the clues of Yong Zhi! CTOnews.com, April 1, China's first high temperature superconducting electric levitation test system independently developed by CRRC Changke Co., Ltd. recently successfully completed its first suspension operation, with a speed of more than 600km / h, marking an important technological breakthrough in the field of high temperature superconducting electric levitation in China.

CTOnews.com learned from the official Wechat account that the high temperature superconducting material can be transformed into a superconducting state above the liquid nitrogen temperature (77K-196C), the DC resistivity decreases to zero, and there is no heat loss when the current flows through the superconducting material, so it can carry more current, thus generating a super magnetic field. Based on this principle, superconducting electric maglev relies on the interaction between vehicle superconducting magnet and ground "8" shaped suspension coil to realize self-suspension, self-guidance and self-stabilization. the superconducting electric maglev technology based on this principle is considered to be one of the "commanding heights" of the current rail transit technology in the world.

In addition, the news shows that the suspension operation has fully verified the key core technologies of the superconducting electric maglev transportation system, such as superconducting magnet, linear synchronous traction, induction power supply and low temperature refrigeration. it is proved that the high temperature superconducting electric levitation all-element test system has the advantages of high speed, safety, green, intelligence, comfort and strong environmental adaptability.
