Abstract: A protective wall system enclosing a danger zone around an alternator includes a front wall disposed at a front end of the wall system; a back wall disposed at a back end of the wall system; and a first side wall and a second side wall connecting the front wall and the back wall, wherein the front and the back wall extend parallel to a longitudinal axis of the alternator, and wherein the front wall, the back wall and the first and second side walls are gas-tight. The wall system further includes a gas-tight bottom; a first casing enclosing a rotor and a stator of the alternator, wherein a service area surrounds the first casing; and at least one air guiding device configured to guide at least one of gas and heat from a bottom part of the alternator to an upper part of the alternator.

Abstract: A hydrogen cooled generator assembly includes a hydrogen cooled generator and a fundament, wherein the generator is mounted on the fundament, and wherein the fundament includes at least one cavity underneath the generator. The at least one cavity includes at least one terminal box disposed adjacent to the generator and extending downward from the generator for collection of a plurality of electrical links from the generator; at least one collection box disposed beneath the at least one terminal box having a top wall and a first and a second side wall and configured to guide the plurality of electrical links from the at least one terminal box in a further downward direction; a lateral space; and a seal plate covering the lateral space at an upper end of the lateral space.
