【Abstract】 The magnetic characteristics of the magnetic materials are the key to the design of the hightemperature superconducting transformer. The magnetic properties and the loss characteristics of different magnetic materials are studied in this paper. The test results have demonstrated that compared to the condition of the room temperature, both the saturated magnetic induction and the losses of the materials increase under the liquid nitrogen temperature. The saturated magnetic induction and the losses of the amorphous metals are less than those of the silicon steel plate under the liquid nitrogen temperature. The test provides the foundation for the design of the hightemperature superconducting transformer.更多还原
