VERFAHREN UND EINRICHTUNG ZUM SELBSTREGELNDEN NACHFUELLEN VON HELIUM IN DEN ROTOR EINES SUPRALEITENDEN GENERATORS

摘要

To effect a self-regulating replenishment of helium from a reservoir into a helium pool in the superconducting rotor of a generator, in which helium in the pool boils at subatmospheric pressure, and a portion of the helium being transferred from the reservoir changes to the vapor phase, and in which both helium phases are delivered into the helium pool at a distance from the axis of rotor rotation, the two helium phases are separated from one another, and the liquid and vapor phases are introduced separately into the pool at respectively different distances from the axis of rotor rotation, the liquid phase being introduced at a greater distance than the vapor phase from the axis, and the vapor phase being introduced into the pool at a distance from the axis of rotor rotation which is greater than that of the vapor/liquid interface in the pool.
