Verfahren und Vorrichtung zum schnellen Druckabbau in einer Anlage, insbesondere bei einem wasserstoffgekühlten Generator

摘要

A process and device are disclosed for quickly reducing pressure in an installation having at least one first and one second housing part (3, 4). The first housing part (3) contains in the normal state a hydrogen atmosphere under overpressure separated by a hydrogen seal (6) from the inside of the second housing part (4). When the hydrogen seal (6) breaks down, hydrogen overpressure is evacuated through a quick emptying pipe (8) in communication with the inside of the second housing part (4) through a venting pipe (9). The invention is preferably used in hydrogen-cooled generators.
