Abstract

The cooling arrangement of the superconducting field winding of a turbo-generator contains a coolant chamber, in which a vaporous and a liquid phase of a coolant are contained, and to the vapor space of which a coolant discharge line with a high flow resistance is connected. To prevent excessive over-pressure in the coolant chamber in the event of a quench, a buffer tank is also connected to the vapor space via a connecting path having a relatively low flow resistance.
