Abstract
Provided is a superconducting coil having a spiral structure for a current limiter. The coil includes: a first superconducting tape, a second superconducting tape, and an insulating isolation layer, where the first superconducting tape and the second superconducting tape have spiral structures, an end of the first superconducting tape at a spiral center is connected to an end of the second superconducting tape at the spiral center, the instating isolation laser is filled between the first superconducting tape and the second superconducting tape, and a spacing between the first superconducting tape and the second superconducting tape gradually increases from the spiral center to an outer spiral periphery.
