Title:
DEVICE FOR EVALUATING PERFORMANCE OF SUPERCONDUCTIVE COIL FOR HIGH-TEMPERATURE SUPERCONDUCTIVE ROTARY MACHINE AND METHOD FOR EVALUATING PERFORMANCE OF SUPERCONDUCTIVE COIL THEREBY
Document Type and Number:
WIPO Patent Application WO/2019/103253
Kind Code:
A1
Abstract:
The present invention relates to a device for evaluating the performance of a superconductive coil for a high-temperature superconductive rotary machine and a method for evaluating the performance of a superconductive coil thereby. The technical gist of the present invention is to provide schemes for evaluating the stability of a superconductive coil and verifying the reliability thereof, to evaluate/confirm whether or not the same can be commercialized, and to evaluate/confirm the threshold current of a superconductive wire for manufacturing a superconductive coil or the upper limit of the operating current thereof, and is characterized in that the electromagnetic, thermal, and mechanical performances of a superconductive coil for a second-generation high-temperature superconductive rotary machine can be evaluated. The present invention, configured as above, is characterized in that refrigerant supply setup can be freely varied during cooling of a bobbin for cooling a superconductive coil, the magnitude of the electric current through an outer stator can be easily changed according setup control, thereby making it possible to differently adjust the magnitude of a time-variant magnetic field applied to the superconductive coil, and it accordingly becomes possible to set and control an evaluation environment identical to the actual use environment in which the superconductive coil is to be used, thereby securing the reliability of evaluation of performance of the superconductive coil.
