Anhui will be the first power sub -perception laboratory in China

During the "Double Creation Week", the world's first quantum current transformer was displayed

On September 17, during 2022, during the National Volkswagen Entrepreneurship Innovation Activity Week, the reporter learned from the National Grid Exhibition Station of the Hefei main venue that the world's first quantum current intestines have been successfully launched in Hefei. Personal Power Perception Laboratory.

The world's first quantum current transformer is the latest innovative achievement of the "heavyweight" exhibited by the State Grid. At the national power grid booth at the main venue of Hefei, the real scene of the laser running in the current intestines is truly simulated. Many audiences are interested in this humble "small head", and they will take pictures here.

"The device you see now is the world's first quantum current transformer independently developed by the Anhui Academy of Electrical Sciences. It has been running smoothly at the Hefei substation. The high -precision measurement of current. "The project leader Zhao Long introduced.

For a long time, traditional current transformers have magnetic saturation problems because of iron cores. There are distortion when measuring large currents, which will affect the reliability and stability of power supply. In order to solve this problem, the In -depth cooperation between Anhui Academy of Electric Science and China and China University of Science and Technology took the lead in introducing quantum precision measurement technology into the power industry, and successfully developed the world's first quantum current transformer at the end of August. After the collaboration and commissioning of Hefei Power Supply Company, the first set of equipment was successfully put into the network at the 110 kV diving road transformation station recently.

"The quantum current transformer uses diamond as a sensor. Through a non -contact magnetic field method, and then through a certain decoding method, it breaks through the technical difficulty. Compared with traditional current transformers, its volume is only 1/10 of the past 1/10 of the past 1/10 , Light weight, and there will be no inaccurate measurement. "Zhao Long said.

At present, Anhui is accelerating the construction of the first domestic power perception laboratory. In the next step, it will also be based on Hefei to aim at the direction of quantum intelligent energy measurement, quantum state detection, quantum sensor and other directions to continuously develop electrical sub -precision measurement "new blue ocean".
