Abstract

The embodiment of the invention discloses a high-temperature superconducting tape detection system. The detection system comprises a magnetic circuit detection device and a two-dimensional scanning platform which are sequentially arranged in the moving direction of a superconducting tape to be detected, the magnetic circuit detection device and the two-dimensional scanning platform are arranged in a sealed Dewar tank containing liquid nitrogen, and the portion, located in the Dewar tank, of the superconducting tape to be detected is located below the liquid level of liquid nitrogen; the magnetic circuit detection device comprises excitation components and magnetic circuit measurement components; the two-dimensional scanning platform comprises a re-excitation component, a two-dimensional scanning support frame and a Hall probe assembly which are arranged in the moving direction of the superconducting tape to be detected, the Hall probe assembly is arranged on the two-dimensional scanning support frame, Hall probe needles on the Hall probe assembly are right opposite to the superconducting tape to be detected and located below the liquid level of liquid nitrogen. According to the high-temperature superconducting tape detection system, the detection system does not need to be matched with a precise transmission system, and fine measurement of the superconducting tape to be detected is rapidly achieved.

Description

technical field [0001] The invention relates to the technical field of high temperature superconductivity, in particular to a high temperature superconducting tape detection system. Background technique [0002] Superconducting electrical devices such as high-temperature superconducting current limiters, magnetic energy storage systems, and controllable reactors are more and more widely used in the field of electric power. Superconducting tape is an essential material for these devices, which directly affects their performance. The industrialized production of superconducting tape has been realized, but the subsequent problem is to analyze and test the mass-produced tape to determine whether it meets the usage standards. [0003] In the prior art, the Hall matrix measurement method is mostly used, and the use of the Hall matrix measurement method requires that the vibration of the phase position of the superconducting tape to be measured and the Hall probe is extremely small...
