Research on Design Method of High Current Transmission Busbar for Superconducting Magnet Power Supply of Fusion Device

In this paper, a bipolar matrix laminated busbar based on water-cooled structure is proposed. By comparing the advantages and disadvantages of inductance calculation of circular conductor array laminated busbar, circular conductor coaxial transmission busbar and matrix laminated busbar, the matrix laminated busbar is chosen. Through the analysis of the influence of multi-variable parameters, laminated dislocation, water hole size, intermediate conductor layer and other different structures on the electromagnetic performance of the busbar, combined with the installation requirements, the optimal busbar structure is finally selected to provide a design reference for the large-scale popularization and application of bipolar matrix laminated busbar.
