Abstract
A method and device for quick pressure relief in a hydrogen-cooled generator system. The hydrogen-cooled generator system at least includes a first and second housing part and a hydrogen seal that separates the first housing part from the interior of the second housing part. In the normal state, the first housing part contains a hydrogen atmosphere at overpressure that is separated from the interior of the second housing part by the hydrogen seal. The quick pressure relief method includes the steps of lowering the pressure of the overpressure hydrogen in the first housing part through a quick discharge line upon failure of the hydrogen seal, and exhausting gas from the interior of the second housing part through a bleed line that is connected to the quick discharge line. The quick pressure relief device includes a quick discharge line for relieving pressure from the first housing part upon a failure of the hydrogen seal, and a bleed line fluidically connected to the quick discharge line and to the interior of the second housing part.
