Title
(DE) ANLAGE MIT ELEKTRISCHEM VERBRAUCHER
(EN) SYSTEM HAVING AN ELECTRIC CONSUMER
(FR) INSTALLATION ÉQUIPÉE D’UN CONSOMMATEUR ÉLECTRIQUE
Abstract
(DE)
Anlage mit elektrischem Verbraucher, insbesondere mit Antrieb, insbesondere mit wechselrichtergespeistem Elektromotor, wobei die Anlage ein Elektrogerät mit Schaltvorrichtung und Leitungen, insbesondere Schleifleitungen, aufweist, wobei eine erste der Leitungen im Normalbetrieb für das Führen der ersten Phase einer Drehspannung vorgesehen ist, wobei eine zweite der Leitungen eine zweite Phase der Drehspannung führt, wobei eine dritte der Leitungen eine dritte Phase der Drehspannung führt, wobei der Verbraucher aus den Leitungen im Normalbetrieb mit Drehspannung versorgbar ist, wobei die Schaltvorrichtung derart geeignet ausgeführt ist, dass im Normalbetrieb die erste Leitung mit der ersten Phase der Drehspannung verbunden ist und dass im Sicherheitsfall die erste Leitung von der ersten Phase der Drehspannung abgetrennt und mit der zweiten Phase der Drehspannung verbunden wird oder ist.
(EN)
The invention relates to a system having an electric consumer, in particular having a drive, in particular having an electric motor supplied by an inverter, wherein the system has an electric device having a switch apparatus and lines, in particular conductor lines, wherein a first of the lines, in normal operation, is provided for conducting the first phase of a three-phase voltage, wherein a second of the lines conducts a second phase of the three-phase voltage, wherein a third of the lines conducts a third phase of the three-phase voltage, wherein, in normal operation, the consumer can be supplied with three-phase voltage from the lines, the switching apparatus being suitably designed such that, in normal operation, the first line is connected to the first phase of the three-phase voltage and that, as a precaution, the first line is disconnected from the first phase of the three-phase voltage and is or becomes connected to the second phase of the three-phase voltage.

L’invention concerne une installation équipée d’un consommateur électrique, en particulier à entraînement. L’installation est en particulier équipée d’un moteur électrique alimenté par onduleur, l’installation comportant un appareil électrique équipé d’un dispositif de commutation et de lignes, en particulier de lignes de contact. En fonctionnement normal, une première desdites lignes est prévue pour conduire la première phase d’une tension triphasée, une deuxième desdites lignes conduisant une deuxième phase de la tension triphasée, et une troisième desdites lignes conduisant une troisième phase de la tension triphasée. Le consommateur peut être alimenté en tension triphasée à partir des lignes, en fonctionnement normal. Le dispositif de commutation est réalisé de manière convenable, de manière à ce que, en fonctionnement normal, la première ligne est connectée à la première phase de la tension triphasée, et à ce que, en cas d’urgence, la première ligne est déconnectée de la première phase de la tension triphasée et connectée à la deuxième phase de la tension triphasée.
