PATENTANSPRÜCHE:PATENT CLAIMS: 1. Sterndreieckschalter für Hochspannung, dadurch gekennzeichnet, daß lediglich ein Satz von Leistungsschaltstellen vorgesehen ist, deren bewegliche Schaltelemente derart durchgebildet sind, daß sie am Ende ihrer Ausschaltbewegung mit Gegenkontakten nach Art einer Trennschaltstelle in Eingriff kommen.1. Star-delta switch for high voltage, characterized in that only one set of power switching points is provided, the movable switching elements of which are formed in this way are that at the end of their switch-off movement with mating contacts in the manner of an isolating switch point come into engagement. 2. Sterndreieckschalter nach Anspruch 1, dadurch gekennzeichnet, daß die Leistungsschaltstellen zu einem Sternpunkt verbunden sind und die Gegenkontakte mit den offenen Motorwicklungen in Dreieck geschaltet sind.2. Star-delta switch according to claim 1, characterized in that the power switching points are connected to a star point and the mating contacts with the open motor windings are connected in delta. 3. Sterndreieckschalter nach Anspruch 2, dadurch gekennzeichnet, daß die beweglichen Kontakte in Dreieckschaltstellung so weit von den Gegenkontakten der Leistungsschaltstellen entfernt sind, daß eine sichtbare Trennstrecke von der erforderlichen Schlagweite geschaffen ist.3. Star-delta switch according to claim 2, characterized characterized in that the movable contacts in the delta switch position so far from the mating contacts of the power switching points are removed so that a visible isolating distance is created by the required striking distance. 4. Sterndreieckschalter nach Anspruch 3, dadurch gekennzeichnet, daß er mit dem nächsten in Reihe liegenden Leistungsschalter in der Weise verriegelt ist, daß eine Umschaltung von Dreieck auf Stern nur bei geöffnetem Leistungsschalter möglich ist.4. star delta switch according to claim 3, characterized in that it is connected to the next in series circuit breaker is locked in such a way that a changeover of Delta to star is only possible when the circuit breaker is open.
