The invention discloses a superconducting cable adapter, which is used for connecting a three-phase coaxial superconducting cable and a metal closed superconducting power transmission line, and comprises a heat insulation cylinder containing liquid nitrogen; an adapter conductor arranged in the heat insulation cylinder, wherein the adapter conductor is respectively connected with a three-phase coaxial superconducting cable and a basin-type insulator of a metal closed superconducting power transmission line; the adapter conductor is used for converting coaxially arranged three-phase conductors of a three-phase coaxial superconducting cable into three-phase conductors arranged in a regular triangle shape, and connecting the three-phase conductors arranged in the regular triangle shape with the three-phase conductive seats on the basin-type insulator respectively. According to the invention, the three-phase adapter conductor is arranged in the heat insulation cylinder and is connected with the three-phase conductor layer of the three-phase coaxial superconducting cable and the three-phase conductive seat on the basin-type insulator, so that the connection between the three-phase coaxial superconducting cable and the metal closed superconducting power transmission line is realized.
Description
technical field [0001] The invention relates to the technical field of power equipment, in particular to a superconducting cable adapter. Background technique [0002] A superconductor is a conductor with zero resistance at a critical temperature, which can reduce the resistance loss during electric energy transmission. The superconductor works at a temperature of 77K and needs to be immersed in liquid nitrogen to exhibit superconducting properties. Superconducting transmission methods mainly include three-phase coaxial superconducting cables and metal-enclosed superconducting transmission lines. In engineering, when these two methods are used at the same time, it is necessary to manufacture corresponding transfer parts to realize mechanical and electrical connections of different structures. Guaranteed low-temperature performance, electrical conductivity, and insulation performance. At present, there is no product with this function. Contents of the invention [0003] Th...
