Study on the High Temperature Superconducting Current Leads for Large Scale Superconducting Magnet

As an effective way to reduce the heat leakage, High Temperature Superconducting (HTS) current leads were widely used in the superconducting magnets system. In this paper, the structure and materials of HTS current leads for large scale superconducting magnets were presented. Furthermore, the thermal characteristics of HTS current leads were described. To reveal the influence of insulating structure on the electrical strength of HTS current lead under normal operating condition and fault operating condition, the electrical analysis of a 16 kA HTS current lead were performed based on finite element technology. The simulating results indicate the dielectric strength of the HTS current lead is enough.
