Abstract

The invention provides a device and method for measuring the quench recovery characteristic of a superconducting tape. According to the device and method disclosed by the invention, a constant currentsource is connected to a controllable impact power supply in parallel, so that currents are continuously loaded for the superconducting tape by the constant current source after impact currents are finished; the voltages of two ends of the superconducting tape are synchronously measured through a data control unit, and whether the superconducting tape is recovered to a superconducting state or not is judged through voltage values; special treatment on a superconducting tape sample to be tested is not needed, and testing can be completely performed in a practical application environment; and in addition, the structure is simple, so that millisecond-grade measurement response speed is realized.

Description

technical field [0001] The invention relates to the field of electric power measurement, and more particularly, relates to a device and method for measuring the quench recovery characteristic of a superconducting strip. Background technique [0002] Superconducting tape is a material with zero resistance characteristics in a specific environment, and is generally divided into low-temperature superconducting materials and high-temperature superconducting materials. Among them, bismuth-based and yttrium-based materials are the most widely used high-temperature superconducting materials, and mass production has been achieved on a certain scale. With the continuous improvement of the preparation technology of high-temperature superconducting materials, the cost performance of high-temperature superconducting strips has been greatly improved, which has greatly promoted the development of high-temperature superconducting power technology. [0003] At present, many superconducting...
