Title:
CONNECTION METHOD FOR YBCO SUPERCONDUCTING MATERIAL-BASED SUPERCONDUCTING CABLE
Document Type and Number:
WIPO Patent Application WO/2020/253085
Kind Code:
A1
Abstract:
The present invention relates to the technical field of superconducting cables, and in particular to a connection method for a YBCO superconducting material-based superconducting cable. The superconducting cable is provided, in sequence from the inside to the outside along the radial direction thereof, with a wire core, a first low-temperature cold insulating layer, a superconducting layer, a second low-temperature cold insulating layer, a support ring, a low-temperature pipeline, an armored copper wire, and an outer protective layer. An end part of the superconducting cable is provided with a cut-off sheath. The connection method comprises: the wire core passing through the interior of a hollow copper tube for connection; the low-temperature cold insulating layers and the superconducting layer all being connected by means of spiral winding; the low-temperature pipeline being directly docked; the outer side of the connected low-temperature pipeline being extruded into an outer protective layer; and pulling a fastening ring and fastening the fastening ring on a connecting end to complete connection. In the field of superconducting cable connection, the present invention is convenient to operate, reduces the wear on a superconducting cable, reduces the occurrence of Joule loss, and also reduces heat leakage by an external current lead during electrical connection.
