METHOD AND APPARATUS FOR COOLING SUPERCONDUCTING CABLE

摘要

FIELD: physics.SUBSTANCE: invention relates to cooling long cryogenic systems and can be used to cool a superconducting cable line. The apparatus has a long cryostat 1, a cryogenic support system 2 and buffer tanks 3. A coolant is passed through the channel in the cryostat which is formed by the gap between an inner pipe and the superconducting cable from the buffer tank 3 at one of the ends of the ends of the long cryogenic systems. At the second end of the long cryogenic system, the coolant accumulates in a second buffer tank 3. The required coolant temperature is maintained in cryogenic systems (refrigeration apparatus) optimally arranged on the length along the long cryogenic system. When filling (evacuating) the buffer tank to a defined level, there is change in direction of movement of the coolant to the reverse direction and filling (evacuation) of the buffer tank at the other end of the cable begins.EFFECT: invention increases efficiency, reduces the cost and improves reliability of operation.3 cl, 1 dwg
