Title:
SUPERCONDUCTING CABLE, AND ELECTRIC POWER TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/002880
Kind Code:
A1
Abstract:
[Problem] To provide a superconductive cable which is capable of storing magnetic energy while performing electric power transmission between a power source having an output that fluctuates over a short time period, and a load, and which is capable of significantly increasing the amount of energy that can be stored, by causing mutual inductance to act between an outward superconductive line and a return superconductive line. [Solution] A superconductive cable 12 for performing electric power transmission between a power source 11 having an output that changes over time, and a load 13, is provided with an energy storing means including: a first superconductive wire 12a which is connected between a positive electrode side of the power source 11 and the load 13, and which is wound in a helical shape with a prescribed angle with respect to the longitudinal direction of a core material 14 comprising a non-magnetic body; and a second superconductive wire 12b which is connected between a negative electrode side of the power source 11 and the load 13, is wound in a stacked manner onto the core material 14, so as to be insulated from the first superconductive wire 12a, and which is wound in a helical shape with a prescribed angle with respect to the longitudinal direction of the core material 14, so as to generate a magnetic field in the same direction as a magnetic field that arises when a current flows through the first superconductive wire 12a.
