Abstract:
1. A stop joint for a superconducting cable, which is installed on lines of superconducting cables connected to terminal structures, comprising: a vacuum chamber provided with lead-in holes on both sides; a nitrogen chamber structure which is accommodated inside the vacuum chamber and is connected to cooling fluid flow paths of the superconducting cables when the superconducting cables are led in; an electrode structure which is disposed inside the nitrogen chamber structure to be electrically connected to conductors of the superconducting cables led in from both sides of the nitrogen chamber structure; a flow path separation member which is bonded to the electrode structure the electrode structure and is connected to the nitrogen chamber structure to block communication between first and second flow paths; and recovery holes which are provided in the nitrogen chamber structure on both sides of the flow path separation member to communicate with the first and second flow paths, and are connected to recovery pipes.
