Embodiment

[0123] In the embodiment, one end of a superconducting cable 10 with an outer diameter of 150 mm and a cable length of 50 m is connected to the terminal connecting portion 1, and the other end is used as a fixed end to construct a simulation model from the end (equivalent to the fixed end) of the stationary area to the terminal Superconducting cable line of connection 1 (see Picture 10 ). For the case where different shapes of the compensation part OS are provided (including straight laying), the amount of thermal contraction when cooling from room temperature to the temperature of liquid nitrogen is compared with the amount of thermal expansion when the temperature is raised from liquid nitrogen to room temperature. Specifically, using an observation device to which radiation such as X-rays or γ-rays are applied, the inside of the movable conductor connection terminal 50 of the terminal connection portion 1 was observed, and the amount of movement of the conductor plug 51 in t...

Abstract

In a superconducting cable line in which a superconducting cable is connected to a terminal connecting portion or an intermediate connecting portion, the compensation portion of the superconducting cable is laid in a curved manner near the terminal connecting portion or the intermediate connecting portion. On the other hand, when it is assumed that the superconducting cable can move in this compensating part, the outer tube of the superconducting cable is fixed so that the movement amount of the superconducting cable accompanying thermal expansion and contraction of the cable core becomes the largest, and the maximum amplitude part cannot move.

Description

Technical field [0001] The present invention relates to a superconducting cable line having a terminal connection part or an intermediate connection part. Background technique [0002] In the past, there has been known a superconducting cable in which a superconducting wire in a superconducting state is used as a conductor under extremely low temperature conditions. Superconducting cables are expected to be able to transmit large currents with low loss, and are being developed for practical use. [0003] figure 2 An example of a superconducting cable is shown. figure 2 The superconducting cable 10 shown is a single-core type superconducting cable in which a single-core cable core 11 is housed in a heat insulating tube 12. [0004] The cable core 11 is composed of a support tube 111, a superconducting conductor layer 112, an electrical insulating layer 113, a superconducting shielding layer 114, a normally conductive shielding layer 115, a protective layer 116, and the like. The sup...
