摘要： To provide a cooling method of a superconducting cable line wherein moistures contained in the cable in the superconducting cable line after laid is removed before cooling, so that solidification of the moistures can be prevented from clogging of piping including a coolant flow channel and a return pipe. There is provided an inert gas generating vessel so that before the coolant is flown into the superconducting cable line 15, the inert gas is blown into the cable line from an inflow pipe 23 connected with a supply pipe 19′ and is discharged from a discharge pipe 22 together with the gas. The inert gas is preheated by a heater 3 before feeding it into the cable line. The discharge pipe 22 connected with a discharge side B of the return pipe 19 is provided with a moisture measuring instrument 20 to measure a moisture content of the discharged gas.

摘要： A method and an apparatus are provided by which a high temperature superconductor can be cooled to a lower temperature easily and conveniently at a low cost. In the cooling method and apparatus according to the present invention, a high temperature superconductor constituting a cable (50) is cooled by liquid refrigerant (41). The refrigerant (41) is cooled by a refrigerator (10) to or below the freezing point which is given by the refrigerant having a stationary state in the cooling system. The cooled refrigerant is forced to flow and circulated by a pump (34), and such a physical action maintains the refrigerant in a fluid state at a temperature equal to or lower than the freezing point. A viscometer (61) may be used to measure the viscosity of the refrigerant to modulate the flow rate of the refrigerant according to the measured viscosity. According to the present invention, liquid nitrogen is maintained in a fluid state at approximately 45 K, for example.
