摘要：
The stack structure of REBCO tapes is an effective way to increase the current carrying capacity. However, under the influence of anisotropy and high aspect ratio, REBCO tape has a low utilization rate in the stack structure. The purpose of this paper is to optimize the stack structure to improve the utilization rate of REBCO tapes. In order to calculate the critical current in the electric network model of stacked structure, the J model is introduced first. Then, based on the electric network model, the influence of different stack structures (including normal REBCO tape and defective REBCO tape) on the critical current is analyzed. The optimized structure can carry more currents, which is conducive to the development of REBCO tape applications.
