Superconducting cable laying system

Abstract

The invention discloses a superconducting cable laying system, which comprises a cable drum, a cable drum driving device, a cable pulley, a cable conveyor, a traction steel wire rope and a hydraulic winching machine, the cable drum driving device is an electric roller assembly arranged on the cable drum and can drive the cable drum to rotate to pay off the superconducting cable; the end part of the superconducting cable is connected with a hydraulic winching machine through a traction steel wire rope, and the hydraulic winching machine drags the superconducting cable; a cable pulley and a cable conveyor are sequentially arranged on a laying path of the superconducting cable at intervals, a pulley structure at the top of the cable pulley enables the superconducting cable to form rolling friction when the superconducting cable moves, and the cable conveyor provides conveying power for a middle-section cable. The external force borne by the superconducting cable can be reduced as much as possible when the superconducting cable is laid.

Description

technical field [0001] The invention relates to a superconducting cable laying system used in the field of superconducting cable laying. Background technique [0002] At present, conventional cable laying is generally completed by mechanical equipment, including hoists, conveyors and other equipment, with a certain degree of mechanization. While laying, rely on the observation and experience of skilled workers to judge whether the cable is deformed and worn during the laying process to determine whether it meets the mechanical properties of the cable, such as lateral pressure. The high-temperature superconducting cable has a larger outer diameter and heavier weight than the conventional cable. At the same time, it has extremely high requirements for the vacuum insulation of the cable insulation tube. There is a fragile refrigerant insulation layer on the outside of the superconducting cable. Excessive lateral pressure leads to deformation or even damage, which will lead to ...

AI Technical Summary

Problems solved by technology

Compared with conventional cables, high-temperature superconducting cables have larger outer diameters and heavier weights. At the same time, the requirements for vacuum insulation of cable insulation tubes are extremely high. There is a fragile refrigerant insulation layer on the outside of superconducting cables. Excessive lateral pressure leads to deformation or even damage, which will lead to a sharp drop in superconducting performance, and further make the entire cable scrapped, causing serious losses
