Abstract

The invention provides a superconducting tape testing device which comprises a testing station and a Duwa container wherein the testing station further includes a base; a stretching part consisting of several first screw rods that stand vertically on the base and a sliding plate cooperating with the first screw rods; a fixing part consisting of a lower clamping body arranged on the base and an upper clamping body arranged in a rotation manner on the sliding plate; and a twisting part consisting of several rotation plates arranged on the upper clamping body through several vertical rods. The rotation plates can drive the upper clamping body to rotate. The Duwa container is filled with liquid nitrogen which cools the superconducting tape to a superconducting state. The superconducting tape testing device of the present invention integrates the functions of tape fixing, stretching and twisting and is capable of performing critical current testing under stretching and twisting combined stresses, and the stretching and twisting combined stresses can be easily adjusted. Therefore, the testing device has high testing efficiency.

Description

technical field [0001] The invention relates to the technical field of superconducting cables, in particular to a superconducting tape testing device. Background technique [0002] With the development of superconducting technology, superconducting materials have been gradually applied to fields such as electricity and medicine. A number of superconducting cables have been running on nets at home and abroad, and MRI (magnetic resonance imaging) with high resolution and made of superconducting magnets has been used for physical examination. It can be said that superconducting tape is the most important application form of superconducting materials. [0003] During the use of superconducting strips, it is inevitable to be subjected to tensile and torsion forces. For example, during the manufacture of superconducting cables, superconducting strips are regularly twisted on the support at a certain angle and pitch, and are simultaneously subjected to The effect of axial tension...
