Method and system for testing impact recovery characteristics of high-temperature superconducting tape

The invention belongs to the technical field of high-temperature superconducting tape characteristic research, and particularly relates to a method and system for testing impact recovery characteristics of a high-temperature superconducting tape. According to the high-temperature superconducting tape impact recovery characteristic test method and system provided by the invention, by setting the delay time of a delay relay, the small current output by a constant-current steady-current source flows through a sample of a high-temperature superconducting tape after the impact current of an impactcurrent source becomes zero, so that the characteristics of the high-temperature superconducting tape in the impact process are not influenced and the change conditions of parameters such as voltage,current and the like in the recovery process can be immediately tested after the impact is ended; the impact characteristic and the recovery characteristic of the high-temperature superconducting tapecan be synchronously and a
