Experimental Study of the Vibration Adaptability of High Temperature Superconducting Coils Cured With Epoxy Resin

In this article, the vibration adaptability of high-temperature superconducting (HTS) coils after primary curing and secondary curing was experimentally studied. Three HTS coils were fabricated using YBCO tape. First, the three coils were cured with MY750 epoxy resin, and random vibration experiments were independently performed in the
x
-,
y
- and
z
-directions. Second, two of the three coils were selected to be cured together with the same epoxy resin in a metal coil case, and the same vibration tests were performed again. The feasibility and effectiveness of the primary and secondary curing processes were confirmed by comparing the voltage-current (
U-I
) curves measured before and after curing and vibration tests. The experimental results showed that there was no performance degradation of the HTS coils cured by the primary and secondary curing processes after 20 g rms random vibration tests. The results of this article could provide a new choice for the HTS coil curing process.
