  • Device for checking an electrical machine cooling system
    Patent number: 4250744
    Abstract: The invention relates to devices for checking the conditions of the coolant at the output of the coolant feed unit of an electrical machine with cryogenic cooling.The device for checking the condition of the coolant comprises a hollow rotor, in which cryogenic temperature is maintained. Located inside the hollow rotor at one end and coaxially with the rotor is a coolant feed unit having a stationary part made in the form of two coaxial tubes disposed with a gap with respect to each other and a movable part. One end of the coolant feed unit communicates with a coolant supply tank while the other end communicates with a coolant collecting chamber, which, in turn, communicates with a unit for transferring the coolant into a liquid coolant receiver tank disposed at the other end of the hollow rotor and made, identically to the unit, in the form of two coaxial tubes.
