Abstract
Dispositif de protection des aubages mobiles d'une turbine à vapeur. Conformément à l'invention, on effectue une prise de pression PE à l'échappement, et une prise de pression D dans l'étage à protéger. PE et D sont envoyés, par l'intermédiaire de soufflets 25 et 26, sur le bras 27 d'une balance à équilibre de couples 28, suivant des directions et en des points tels que la pente de la droite obtenue en écrivant l'équation de la balance corresponde à celle de la droite définissant la protection désirée. La balance 28 comporte en outre soit un ressort 29 définissant une consigne correspondant à l'ordonnée à l'origine de la droite de protection, ainsi qu'une butée 31 et un contacteur 30 relié à un dispositif d'alarme ou de sécurité, soit un transmetteur de force 32 permettant un traitement analogique de l'information obtenue. L'invention trouve son application dans le domaine de la production d'énergie par turbines à vapeur.
