Design of Current Lead for 50MVA HTS Transformer

Article Preview

Abstract:

Compared with the conventional transformer, high temperature superconducting (HTS) transformer can effectively improve the efficiency of the system. The current lead of HTS transformer is a main part that leads to leak out heat, and its thermal leakage loss greatly influents the performance of cryogenic system. So it is important to design and optimize the current lead. In this paper, the current lead of a 50MVA HTS transformer is designed, depended on the calculated conclusion of temperature field with FEM method, the optimization of the current lead is carried out to decrease heat losses.
