Abstract

The embodiment of the invention discloses a superconductive strip material surface layer, and the surface layer is provided with a mesh grid structure which is disposed on the surface of a superconductive strip material. The surface layer provided by the invention solves a technical problem that the steam layer generated by the surface when a superconductor is in a normal resistance state greatlyreduces the heat exchange efficiency between the superconductor and liquid nitrogen. In addition, the embodiment of the invention also discloses a superconductive strip material and a superconductivecoil.

Description

technical field [0001] The present application relates to the field of electrical technology, in particular to a surface layer of a superconducting strip, a superconducting strip and a superconducting coil. Background technique [0002] The resistive superconducting current limiter is a power device that utilizes the superconducting state-normal state transition characteristics of the superconducting strip. When the power grid normally transmits current, the conductor used in the current limiting unit of the resistive superconducting current limiter is in a superconducting state, and the current can be transmitted almost without loss. When the power grid fails and a short-circuit current is generated, the large short-circuit current will make the conductor used in the current-limiting unit of the resistive superconducting current limiter change to a normal state, thereby showing a large resistance, thereby increasing the system short-circuit impedance of the power grid , to...
