Description

Die Erfindung bezieht sich auf eine Einrichtung zur Erzeugung einer stromabhängigen, vektoriellen Zusatzspannung für Spannungs-, Meß-, Anzeige- oder Reglervorrichtungen, insbesondere zum Steuern von Ne.tzregulierapparaten in Abhängigkeit Von der Leistung, bei der ein stromdurchflossener, gegebenenfalls regelbarer, elektrischer Widerstand vorgesehen ist und die Spannungswickto lung der Vorrichtung über die Enden dieses Widerstandes am Netz liegt. Beispielsweise liegt der elektrische Widerstand in dem Niederspannungskreis des Stromwandlers und ist die Spannungswicklung der Vorrichtung überThe invention relates to a device for generating a current-dependent, vectorial additional voltage for voltage, measuring, display or regulator devices, especially for controlling electricity regulators depending on the Power at which a current-carrying, possibly controllable, electrical resistance is provided and the Spannwickto development of the device over the ends of this Resistance on the network. For example, the electrical resistance is in the low-voltage circuit of the current transformer and is the voltage winding of the device across

»5 diesen Widerstand an die Niederspannungswicklung des Spannungswandlers gelegt. »5 put this resistor on the low voltage winding of the voltage converter.

Soll eine derartige Einrichtung in Mehrphasennetzen oder für mehrere Abzweigleitungen Verwendung finden, so müßte eigentlich für jede Phasenleitung eine derartige Einrichtung vorgesehen werden. Bei Drehstrom würde, da die Summe der Ströme gleich Null ist, bei einer Hintereinanderschaltung der Widerstände kein Meßresultat zu erzielen sein.Should such a device be used in multi-phase networks or for several branch lines Find a use, so should actually be one for each phase line Facility to be provided. In the case of three-phase current, since the sum of the currents is equal to zero, there would be a series connection the resistances no measurement result can be achieved.

Erfindungsgemäß ist daher bei der Verwendung der vorbeschriebenen Einrichtung in Mehrphasennetzen oder für mehrere Abzweigleitungen nur ein gemeinsamer Spannungskreis vorhanden, und die Zusatzspannung wird durch Gegenschaltung der den einzelnen Strömen zugeordneten, in Reihe liegenden Widerstände geliefert. Die Widerstände können auch durch Drosselspulen mit Eisenkern, Kohle, Silite und Eisen in Wasserstoffatmosphäre gebildet werden, also solche, deren Charakteristik der des Stromes oder der der Temperatur in der Anlage angepaßt ist.According to the invention is therefore when using the device described above in multi-phase networks or for several branch lines only one common voltage circuit available, and the additional voltage is connected in series by the counter connection of the individual currents lying resistors supplied. The resistors can also be made using inductors Iron core, coal, silite and iron are formed in a hydrogen atmosphere, that is those whose characteristics match those of the current or the temperature in the system is.

In den Abbildungen sind Ausführungsbeispiele der Einrichtung gemäß der Erfindung dargestellt.In the figures are exemplary embodiments of the device according to the invention shown.

Nach Abb. 1 werden die in einzelnen Stromkreisen liegenden Widerstände 16, 17, in der Weise hintereinandergeschaltet, daß der Widerstand 18 den beiden anderen gegengeschaltet ist. Die Gesamtheit der Widerstände liegt in dem vom Spannungswandler gespeisten Meßinstrumentenkreis.According to Fig. 1, the resistors 16, 17, connected in series in such a way that the resistor 18 is connected against the other two is. The totality of the resistances lies in the measuring instrument circuit fed by the voltage converter.

In Abb. 2 ist eine Einrichtung dargestellt, bei der zwei Abzweigleitungen I und II vorhanden sind. Die im Stromkreis der Sekundärwicklung der beiden Stromwandler liegenden Widerstände sind wieder in Gegenschaltung hintereinandergeschaltet und liegen in dem Spannungskreis des Meßinstrumentes.Fig. 2 shows a device in which there are two branch lines I and II are. The resistors in the circuit of the secondary winding of the two current transformers are again in counter-circuit connected in series and are in the voltage circuit of the measuring instrument.

Die Widerstände sind hier nur alsOhmsche^ Widerstände dargestellt. Sie können jedoch auch 'durch Kondensatoren, induktive Widerstände und Kombinationen davon gebildet werden.The resistances are here only as Ohms ^ Resistances shown. However, you can also use capacitors, inductive resistors and combinations thereof can be formed.
