【Abstract】 In order to meet the special requirements of a small superconducting magnet system for aerospace,we use inductive method to excite the superconducting magnet.The advantage of such a method is that the currents are induced and closed in the superconducting magnet and there is no need to use current leads and superconducting switches.It is very important to reduce the weight and thermal loss of cryostat.In this paper,the basic principle of this inductive method and characteristics of the superconducting transformer are described.The experimental method and results are also given.更多还原
