Embodiment Construction

[0018] The following will be combined with Figure 1-2 The present invention is described in further detail.

[0019] Such as figure 1 As shown, it shows a support structure of parallel strips of a superconducting current limiter, the support structure includes an integrally formed insulating mesh support structure 1, which can be supported by polytetrafluoroethylene or the like. The shape of the insulating mesh support structure 1 is the same as that of the superconducting strip 2, both of which are cuboids, and the mesh in the middle can be in various shapes, such as rectangle, circle, square, polygon or ellipse. hole. In order to ensure the circulation of liquid nitrogen in the net-like support structure, holes are provided on each side of the net-like support structure. The figure shows a circular hole for the circulation of liquid nitrogen.

[0020] Such as figure 2 shown, to apply figure 1 Schematic diagram of the parallel superconducting tape 2 after the support s...

Abstract

The invention relates to a supporting structure of superconducting current limiter parallel strips. The supporting structure comprises an insulating net-shaped supporting structure. Each side surfaceof each mesh of the insulating net-shaped supporting structure is provided with a hole, and the insulating net-shaped supporting structure is clamped between two superconducting strips or between thesuperconducting strips and a current limiter framework. According to the supporting structure for parallel connection of superconducting coils, the supporting structure is a net-shaped cuboid; the shape of the supporting structure is the same as that of the superconducting strips, and the supporting structure is placed between the superconducting strips connected in parallel; meshes can be in various shapes; and the supporting structure is made of a soft insulating material and can meet the requirements of parallel superconducting strips in different winding forms.

Description

technical field [0001] The invention relates to a support structure for parallel strips of a superconducting current limiter, belonging to the technical field of superconducting current limiters. Background technique [0002] Since the discovery of superconductivity, superconductivity and its application have been one of the most active frontier research fields in contemporary science and technology. In particular, the discovery of high-temperature superconductivity has made it possible for superconducting devices to work in the liquid nitrogen temperature zone and the wide application of superconducting devices. So far, many superconducting devices have been developed, such as superconducting cables, superconducting current limiters, superconducting energy storage devices, superconducting generators, superconducting transformers, etc. [0003] The superconducting current limiter has little impact on the power grid during normal operation in the power grid, and has a signif...
