CA 2720449
The invention relates to a tubular turbine generator unit comprising a turbine rotor; a drive shaft, which is connected rotationally fixed to the turbine rotor; an electrical generator having a generator rotor and a generator stator, wherein said generator rotor is at least indirectly driven by said driveshaft; a tubular turbine housing, which encloses the electric generators; a bearing arrangement, which is disposed inside the tubular turbine housing and is used for mounting the drive shaft; characterized in that at least one spatial area which can be flooded is provided in the interior of the tubular turbine housing, which is flooded with water in operation of the tubular turbine generator unit, wherein the generator gap between said generator rotor and said generator stator and the bearing gap of said bearing arrangement are part of the spatial area which can be flooded.
L'invention concerne un ensemble turbine bulbe-alternateur comprenant une roue mobile de turbine, un arbre d'entraînement relié de manière bloquée en rotation à la roue mobile de turbine, un générateur électrique muni d'un rotor et d'un stator, le rotor étant entraîné au moins indirectement par l'arbre d'entraînement, un carter de turbine bulbe enveloppant le générateur électrique ainsi qu'un ensemble palier placé à l'intérieur du carter de turbine bulbe et servant au montage de l'arbre d'entraînement. L'invention se caractérise en ce qu'au moins une zone pouvant être envahie par l'eau se trouve à l'intérieur du carter de turbine bulbe, laquelle zone est envahie par l'eau lorsque l'ensemble turbine bulbe-alternateur fonctionne, l'interstice entre le rotor et le stator du générateur électrique et l'interstice de l'ensemble palier faisant partie de ladite zone.
