Description

Selbsterregte Gleichstrommaschine mit Nebenschlußregelung. Die der Erfindung zugrunde liegende Aufgabe ist die Erweiterung des stabilen Regelbereichs bei selbsterregten Gleichstrommaschinen mit Nebenschlußregelung. Erfindungsgemäß erhält die Gleichstrommaschine eine Zusatzselbsterregung, deren Stromstärke durch einen Strombegrenzer dm größten Teile des Regelbereichs der Maschine praktisch konstant gehalten. wird.Self-excited DC machine with shunt regulation. The the The object on which the invention is based is to expand the stable control range for self-excited DC machines with shunt regulation. According to the invention the DC machine receives an additional self-excitation, the current strength of which by a current limiter practically constant over the largest part of the control range of the machine held. will.

Die Abbildung zeigt ein Ausführungsbeispiel der Erfindung, in welchem als Strombegrenzer ein an sich bekannter Variationswiderstand dient. Es bedeutet: a den Anker der Maschine, e deren Erregerwicklung, die in Reihe mit dem Nebenschlußregler y liegt. Parallel zu diesem Erregerkreise ist ein Zusatzerregerkreis angeordnet, in dem die Zusatzerregerwicklung z und gegebenenfalls ein Vorschaltwiderstand w in Reihe mit dem Variationswiderstand v liegen. Da dieser bekanntlich auch bei Schwankungen der Klemmenspannung in weiten Grenzen nur eine bestimmte Grenzstromstärke durchläßt, wird die Zusatzerregung von den Änderungen der Klemmenspannung nicht beeinflußt und verhält -sich praktisch wie eine konstante Fremderregung. Es ist dadurch ein Zusammenfallen der Widerstandscharakteristik des Erregersystems der Maschine mit dem geradlinigen Teil von deren Leerlaufcharakteristik ausgeschlossen und eine stabile Regelbarkeit bis nahe an die Spannung Null heran gewährleistet.The figure shows an embodiment of the invention in which a known variable resistor serves as a current limiter. It means: a the armature of the machine, e its excitation winding, which is in series with the shunt regulator y lies. An additional excitation circuit is arranged parallel to this excitation circuit, in which the additional field winding z and possibly a series resistor w are in series with the variation resistance v. As it is well known, this also applies to fluctuations the terminal voltage only allows a certain limit current to pass through within wide limits, the additional excitation is not influenced by the changes in the terminal voltage and behaves practically like a constant external excitation. It is thereby a Coincidence of the resistance characteristics of the excitation system of the machine with the rectilinear part is excluded from its idling characteristic and a stable one Controllability up to almost zero voltage guaranteed.

Als Strombegrenzer könnte auch eine elektromagnetische Regeleinrichtung dienen, doch steht diese an Einfachheit der beschriebenen Anordnung nach. Andere als Strombegrenzer geeignete Vorrichtungen sind die Elektronenröhren, die ebenfalls bei veränderlicher Spannung nur eine bestimmte Stromstärke (Sättigungsstrom) durchlassen und daher in ähnlicher Weise wie ein Variationswiderstand verwendet werden können.An electromagnetic control device could also be used as a current limiter serve, but this is inferior to the described arrangement in terms of simplicity. Other Devices suitable as current limiters are electron tubes, which are also suitable If the voltage changes, only allow a certain amount of current (saturation current) to pass and therefore can be used in a manner similar to a variation resistor.
