AI Technical Summary

Problems solved by technology

[0004] At present, traditional high-temperature superconducting magnet performance testing devices are mainly used for testing parameters such as voltage, current, and temperature. They can only obtain the voltage-current performance curve of the magnet, and cannot understand the magnetic field characteristics and deformation characteristics of the magnet.

In addition, the loading of the magnet current is basically in manual mode, the detection efficiency is low, and the synchronization of various parameter monitoring cannot be guaranteed, which affects the detection accuracy
