Description

Die Erfindung stellt eine Schutzanordnung für Netzteile, besonders für Transformatoren u. dgl. dar, die dazu dienen soll, bei Kurzschlüssen, die z. B. innerhalb des Transformators auftreten, ein Abschalten des gestörten Teiles zu erreichen. Sie beruht auf dem Ansprechen eines Schutzrelais, das von zwei an verschiedenen Stellen im Netz herrschenden Strömen der gleichen Phasenleitung und dem zwischen ihnen bestehenden Winkel der Phasenverschiebung abhängig ist. Das Relaissystem besteht dabei aus zwei Magneten b, b1, deren Wicklungen d und d1 von dem Stromwandler g, der auf der einen Seite des Transformators / liegt, gespeist wird, und einem dritten Magneten c, dessen Wicklung e an dem zweiten Stromwandler h anliegt. Der Eisenkern der Spüle e ist in dieser drehbar gelagert und mit einem den magnetischenThe invention provides a protection arrangement for power supplies, especially for transformers and the like. B. occur within the transformer to achieve a shutdown of the disturbed part. It is based on the response of a protective relay, which is dependent on two currents of the same phase line prevailing at different points in the network and the angle of phase shift between them. The relay system consists of two magnets b, b 1 , whose windings d and d 1 are fed by the current transformer g, which is on one side of the transformer /, and a third magnet c, whose winding e is connected to the second current transformer h is applied. The iron core of the sink e is rotatably mounted in this and with a magnetic

Dia Wicklungen sind so angeordnet, daß sich bei normalem Betrieb der Bügel α in der Richtung c, d einstellt. Tritt Kurzschluß oder eine bestimmte Änderung der Phasenverschiebung ein, so wird der Bügel α aus der Normallage, abgestoßen und schwingt aus dieser heraus, bis er bei k Kontakt für die Auslösespule / des betreffenden Schalters gibt. ao final forming bracket α connected, which adjusts depending on the direction of the field in the direction of the magnets c and d or c and d 1. The windings are arranged in such a way that, during normal operation, the bracket α is set in the direction c, d . If a short circuit or a certain change in the phase shift occurs, the bracket α is pushed out of the normal position and swings out of this until it makes contact for the trip coil / the relevant switch at k.
