Title:
METHOD FOR TESTING CABLE CORE FOR SUPERCONDUCTING CABLE, AND COOLING CONTAINER
Document Type and Number:
WIPO Patent Application WO/2014/057565
Kind Code:
A1
Abstract:
Provided are a cooling container and a method for testing a cable core for a superconducting cable, whereby electrical characteristics can be tested along the entire length of a cable core for a superconducting cable. A cable core (100) provided with a superconducting conductor layer (102) is accommodated in a cooling container (1) having a vacuum insulation layer (2a) on at least a portion thereof. The cooling container (1) is filled with a liquid refrigerant (2L). A cooling gas is introduced into a vapor phase (2A) in the cooling container (1), the vapor phase (2A) is placed in a pressurized state at a pressure greater than atmospheric pressure, the superconducting conductor layer (102) is electrified or charged while the superconducting conductor layer (102) is maintained in a superconducting state by the liquid refrigerant (2L), and electrical characteristics along the entire length of the cable core (100) are measured. During this measurement, the pressure of the vapor phase (2A) in the cooling container (1) and the temperature of the liquid refrigerant (2L) are measured without circulative cooling of the liquid refrigerant (2L) in the cooling container (1), and the liquid refrigerant (2L) is monitored on the basis of the measurement results as to whether the state thereof is suitable for continuation of testing.
