FIELD: chemistry.
SUBSTANCE: cryoprovision system containing expendable cryostat is designed to maintain the desired temperature of the cryogenic liquid in high-temperature superconducting (HTS) devices. The difference is that the system further comprises a drain pipe with an installed valve, nitrogen vapour preheater and vacuum pump, a helium gas supply system into a cryostat and bubbling through the cryogenic liquid in the container.
EFFECT: increased efficiency and reliability of maintaining a predetermined temperature level of the cryogenic liquid in HTS windings of electrical machines.
