Abstract

This article studies the influence of flux diverters (FDs) on energy storage magnets using high-temperature superconducting (HTS) coils. Based on the simulation calculation of the H equation finite-element model, FDs are placed at both ends of HTS coils, and the position and structure are optimized. The impact of the diverter structural parameters on the energy storage of the HTS energy storage magnet is explored, and an optimized diverter structure is designed. The rectangle is the most basic structure of FDs, so this article first optimizes the structure of the rectangular FDs and then performs various slotting treatments on the optimized FDs. By comparison, it is concluded that the concave FDs have the best energy storage effect. Then, based on the optimization of the concave FDs, a Γ-shaped structure is obtained, further improving the magnet's energy storage effect. The conclusion of the influence factors can be applied to the optimization design of diverter structures and provide a new perspective for improving energy storage.
