Abstract

In the application of high-temperature superconducting power, AC loss is an important concern. In order to study the narrowing stacked superconducting coil winding way affect ac loss, the winding structure was optimised. Comsol Multiphysics finite element simulation software is used to build a superconducting coil AC loss calculation model based on H equation. The influence of the co-direction current and the reverse current on the AC loss of the superconducting coil is analyzed, and the reasons affecting the AC loss are analyzed from the perspective of the magnetic field. Finally, the effect of turn spacing on the loss characteristics of the two winding methods is studied. The results show that the AC loss is approximately two orders of magnitude lower when the adjacent strip conducts the reverse current than when the adjacent strip conducts the same current. Along with the rising of the coil pitch, when adjacent with carry the same current, ac loss decreases with increasing the pitch, when adjacent zone instead to carry current, ac loss increases with the pitch.
