Embodiment 1

[0019] The longitudinal magnetic field effect curve is as figure 1 It can be seen from the graph that the critical current density of the conductor under the longitudinal magnetic field is greater than that under the transverse magnetic field. For a quasi-isotropic conductor without superconducting tape, the magnetic field generated by it is perpendicular to the central axis Direction, that is, the conductor is in the transverse magnetic field. When the superconducting tape is helically wound outside the quasi-isotropic conductor, the magnetic field generated by the wound superconducting tape is parallel to the direction of the central axis, so the total magnetic field is and The central axis has a certain angle. By twisting the quasi-isotropic high-temperature superconducting conductor, the magnetic field environment in which the conductor is located is changed from a transverse magnetic field to a longitudinal magnetic field, thereby increasing the critical current density of...

Abstract

The invention relates to the technical field of superconductor application, and especially relates to a quasi-isotropic high-temperature superconductor with high engineering current density. A twistedquasi-isotropic high-temperature superconductor is taken as a base body, and is spirally wound by a high-temperature superconducting strip. The quasi-isotropic high-temperature superconductor consists of a conductor core and a jacket. The quasi-isotropic high-temperature superconductor can be formed by the spiral winding of a twisted wire outside the conductor core. The quasi-isotropic high-temperature superconductor structure proposed by the invention based on the longitudinal magnetic field effect takes the twisted quasi-isotropic high-temperature superconductor as the base body, and the ahigh-temperature superconducting strip is spirally disposed on the base body in a winding manner in a mode similar to the manufacturing mode of a superconducting cable. The superconductor provided bythe invention can reduce a vertical magnetic field component, and effectively improves the engineering current density.
