Bei der Auslösung von Hochspannungsmaximalausschaltern benutzte man bisher entweder Reihentransformatoren, an deren Sekundärwicklung die Auslösespulen unmittelbar angeschlossen waren, oder Hochspannungsrelais mit Gleichstromkontaktvorrichtung, wobei die Auslösung durch einen Stromstoß mit Gleichstrom bewirkt wurde. Letztere Ausführung hat vor der ersteren die Vorteile,Up to now, either Series transformers, to whose secondary winding the trip coils were directly connected, or high-voltage relays with DC contact device, with tripping by a current surge with Direct current was effected. The latter version has the advantages over the former,
ίο daß die Auslösespule (wegen der nur vorübergehenden Belastung) kleiner ausgeführt werden kann, und daß die Auslösung stets mit kräftigem Schlag (nicht schleichend) erfolgt. ίο that the release coil (because of the only temporary Load) can be made smaller, and that the release always takes place with a strong blow (not creeping).
In manchen Fällen hat man nun keinen . Gleichstrom zur Verfügung, z. B. in den der Zentrale entfernt liegenden Schaltstellen, so daß man also auf die Verwendung von Wechselstrom angewiesen ist.In some cases you don't have one. Direct current available, e.g. B. in the Central remote switching points, so that one can therefore rely on the use of AC power is dependent.
ao Die vorliegende Erfindung stellt nun eine wesentliche Verbesserung der Auslösung mittels eines Reihentransformators dar, insofern als durch diese die oben angeführten Vorteile der Gleichstromauslösung erreicht werden.ao The present invention now represents a substantial improvement in the release by means of a series transformer, insofar as through this the above-mentioned Benefits of DC tripping can be achieved.
Dies, wird dadurch bewirkt, daß an dem Reihentransformator eine Einrichtung angebracht wird, durch welche bei Überschreitung einer gewissen maximalen Stromstärke ein Kontakt geschlossen wird, welcher-den Stromkreis der Sekundärspule auf die Auslösespule des Hochspannungsschalters schließt.This is accomplished by attaching a device to the series transformer is, through which a certain maximum current is exceeded Contact is closed, which-the circuit of the secondary coil to the trip coil of the high-voltage switch closes.
Zu diesem "Zweck ist das Eisen des Reihentransformators an einer Stelle zwischen A und B unterbrochen (vergl. Fig. I beiliegender Zeichnung). Der durch die Primärwicklung fließende Strom erzeugt an der Unterbrechungsstelle ein magnetisches Feld, welches bewirkt, daß bei Erreichung einer gewissen Stromstärke in der Primärwicklung ein Eisenstück C angezogen wird. Infolgedessen wird der. Eisenweg geschlossen und zugleich zwischen α und b Kontakt hergestellt, wodurch die sekundäre Wicklung des Transformators in Tätigkeit treten kann.For this purpose, the iron of the series transformer is interrupted at a point between A and B (see FIG A piece of iron C is attracted in the primary winding. As a result, the iron path is closed and at the same time contact is made between α and b , whereby the secondary winding of the transformer can come into operation.
Die Verwendung des Apparates geht aus der Schaltungsskizze einer Schaltstelle für Hochspannungswechselstrom nach Fig. 2 hervor. S ist der Hochspannungsschalter, A die Auslösespule desselben, II die Sekundärspule, I die Primärspule.The use of the apparatus is evident from the circuit diagram of a switching point for high-voltage alternating current according to FIG. S is the high-voltage switch, A is its trip coil, II is the secondary coil, I is the primary coil.
