Design of superconducting traction transformer and its thermal analysis

This paper deals with design and thermal analysis of the superconducting single-phase traction transformer. The purpose is to make an electromagnetic design of single phase superconducting traction transformer and also to investigate a distribution of a heat in a cryogen with liquid nitrogen, known as a high temperature superconducting (HTS) material, using FEM software. The outputs of electromagnetic design are geometrical dimensions, basic parameters and losses of transformer, what is an input of thermal transformer model and than time varying waveforms of temperature in certain points of the transformer will be simulated by means of a 3D version of FEM software and the results will be presented and discussed.
