Description

technical field [0001] The invention relates to the field of performance testing of superconducting conductors, in particular to an automatic testing system for the mechanical properties of superconducting conductors. Background technique [0002] With the continuous reduction of traditional fossil energy, countries all over the world have launched the exploration of a new generation of energy. As a clean and efficient energy, the new energy produced by nuclear fusion has attracted widespread attention. The superconducting magnet system is the core component of the nuclear fusion device, including TF coils, CS coils, PF coils and CC coils, and each part of the coils is made of superconducting conductors. During operation, the conductor generally works under the complex environmental conditions of strong magnetic field, extremely low temperature and high current. Therefore, after the design and development of the conductor is completed, the performance of the conductor needs ...

Problems solved by technology

This experiment requires a cyclic test of the mechanical properties of superconducting conductors in a low-temperature temperature zone, which has the characteristics of long duration and large amount of data. The traditional acquisition and test system only collects relevant signals, and does not have the characteristics of analysis and processing. It is impossible to establish a connection control with the instrument, and a lot of manpower is consumed during the experiment and later data processing
