Since, furthermore, it can be assumed that also ; If the other circuit breakers do not trigger exactly at the same time, then finally the entire energy requirement flows through a rectifier for a moment, and this must be torn off at a circuit breaker.
Die beschriebene Gefahr wird erfindungs gemäß dadurch beseitigt, daß mit dem Auslösen eines Selbstschalters sofort die Wechselstromzufuhr zu der ganzen Gleichrichtergruppe unterbrochen, wird. Da hierbei die . Sicherheit besteht, daß jeder mit einem Gleichrichter in Reihe liegende Selbstschalter auf keinen Fall mehr als die einem Gleichrichter zukommende Energie zu unterbrechen hat, so können bei der neuen Schaltung auch kleinere und daher billigere Selbstschalter verwendet werden.The risk described is eliminated according to the invention that with the triggering a circuit breaker immediately the alternating current supply to the whole rectifier group interrupted, is. Since the. There is certainty that everyone with one Rectifiers in series circuit breakers in no case more than those of a rectifier has to interrupt incoming energy, so can also with the new circuit smaller and therefore cheaper circuit breakers can be used.

Each rectifier is preceded by one of the automatic switches f or h , with the moving part of which a contact bridge ^ "or k is connected. In the switched-off position, this bridges two contacts that are
