DEVICE AND METHOD FOR THE DAMPED, NON-CONTACT SUPPORT OF A COOLANT FEED LINE FOR SUPERCONDUCTING MACHINES

摘要

The invention relates to a device for supporting a coolant feed line (310) for superconducting machines (100), having a hollow shaft (320) that can be connected to the superconducting machine (100) in a first region (320'), the coolant feed line (310) being disposed in the interior thereof for feeding the coolant from the refrigeration unit (200) to the superconducting machine (100). A magnetic support (400) is disposed in the first region (320'') of the hollow shaft (320) so that a radial and thus motion-damping, centering force is exerted on the coolant feed line (310). The magnetic support (400) comprises a first (410) and a second (420) magnetic cylinder, wherein the first magnetic cylinder (410) is disposed on the outer jacket of the coolant feed line (310) and the second magnetic cylinder (420) is disposed on the inner face of the hollow shaft (320). The first magnetic cylinder (410) is a cylinder made of highly electrically conductive material having ohmic resistance.
