HTS dc bias coil for 35 kV/90 MVA saturated iron-core fault current limiter

摘要

A superconductive coil with 141,000 ampere-turns designed magnetizing power, made of 17,600 meters BSCCO 2223 HTS tapes, was fabricated and tested. This coil was built for a 35 kV/90 MVA saturated iron-core fault current limiter. Computer simulations on the performance of the coil were carried out using ANSYS. The critical current of the superconducting coil and the dc resistance of the coil, including the non-superconducting joints. were investigated. spatial distribution of the magnetic field was measured and compared with the simulation results. in this paper, we will report the configuration and the key parameters of the coil as well as the experimental and simulation results.
