Title (DE) PUMPTURBINENANLAGE
(EN) PUMP/TURBINE SYSTEM
(FR) ENSEMBLE POMPE-TURBINE
Abstract:
(DE) Die Erfindung betrifft eine Pumpturbinenanlage, umfassend eine Turbine mit einem Turbinenlaufrad sowie einem Turbinenspiralgehäuse; eine Pumpe mit einem Pumpenlaufrad sowie ein Pumpenspiralgehäuse; eine elektrische Maschine, die in einer Triebverbindung mit der Welle steht oder in eine solche bringbar ist; zwischen Turbine und Pumpe ist ein hydraulischer Kurzschiuss herstellbar. Die Erfindung ist gekennzeichnet durch die folgenden Merkmale: die Turbine weist eine höhere Nennleistung auf, als die Pumpe.
(EN) The invention relates to a pump/turbine system, comprising a turbine having a turbine rotor and a spiral turbine casing; a pump having a pump impeller and a spiral pump casing; an electric machine, which has a drive connection to the shaft or can be brought into such a connection; and a hydraulic short-circuit can be produced between turbine and pump. The invention is characterized by the following features: the turbine has a higher rated output than the pump.
(FR) L'invention concerne un ensemble pompe-turbine qui comprend une turbine pourvue d'un rotor de turbine et d'un carter de turbine en volute; une pompe pourvue d'un rotor de pompe et d'un carter de pompe en volute; une machine électrique qui est ou peut être mise en liaison d'entraînement avec l'arbre; un court-circuit hydraulique pouvant être créé entre la turbine et la pompe. L'invention se caractérise en ce que la puissance nominale de la turbine est supérieure à celle de la pompe.
