Description

Anordnung zur Verhinderung periodischer Ausgleichströme beim Zusammenarbeiten einer Gleichstromkommutatormaschine mit einer Akkumulatorenbatterie o. dgl. Wenn eine Akkumulatorenbatterie oder auch eine Batterie elektrolytischer Zeihen an die Spannung einer Gleichstrommaschine gelegt wird, so ändert sich infolge der durch die Stromwendung bedingten Spannungsschwankungen periodisch der in den Leitungen zwischen der Maschine und der Batterie fließende Gleichstrom. Praktisch ist für die Ausnutzung eines derartigen gewellten Gleichstromes im allgemeinen der arithmetische Mittelwert maßgebend. Insbesondere hängt bei Stromverbrauchern, die eine Kombination von Ohmschem Widerstand und großer Selbstinduktion darstellen, die Leistung des Verbrauchers vom Strommittehvert ab. Die Wärmeverluste sind jedoch dem Quadrat des Effektivwertes des Stromes proportional und infolgedessen höher, als dem Mittelwert entspricht. Durch die periodische Änderung des Gleichstromes wird also der Wirkungsgrad der Anlage hexuntergedrückt.Arrangement to prevent periodic equalizing currents when working together a DC commutator machine with an accumulator battery o. The like. If an accumulator battery or a battery of electrolytic drawing to the Voltage of a DC machine is applied, changes as a result of the voltage fluctuations caused by the commutation are periodic in the lines direct current flowing between the machine and the battery. Is convenient for the use of such a corrugated direct current is generally arithmetic Mean value decisive. In particular, depends on electricity consumers who have a combination of ohmic resistance and large self-induction represent the performance of the Consumer from the electricity center. However, the heat losses are the square of the The effective value of the current is proportional and consequently higher than the mean value is equivalent to. The periodic change in the direct current increases the efficiency the system hex suppressed.

Erfindungsgemäß sollen nun diese periodischen Änderungen des Gleichstromes dadurch nach Möglichkeit unterdrückt werden, daß die Verbindungsleitungen zwischen der Maschine und der Batterie eine künstliche erhöhte Selbstinduktion erhalten. Zu diesem Zwecke können .beispielsweise in die Leitungen Drosselspulen eingebaut oder statt dessen die Leitungen durch Eisenkörper hindurchgeführt werden. Besonders diese zweite Möglichkeit ist sehr vorteilhaft, da durch 'die Erhöhung der Selbstinduktion in diesem Falle keinerlei Erhöhung der Kupferverluste auftritt.According to the invention, these periodic changes in the direct current should now are thereby suppressed as far as possible that the connecting lines between the machine and the battery receive an artificially increased self-induction. For this purpose, inductors can, for example, be built into the lines or instead the lines are passed through iron bodies. Particularly this second option is very beneficial because it increases self-induction in this case no increase in copper losses occurs.

In. der Zeichnung ist ein. Ausführungsbeispiel veranschaulicht. Die Leitungsschienen. a1, a2 sind darnach je von einem geschlitzten Eisenring b1, b2 umgelben. Die Eisenringe können dabei gegebenenfalls noch nachträglich in :einer vorhandenen Anlage angebracht werden, so daß sich die Erhöhung der Selbstinduktion ohne Änderungen an den Leitungen selbst erzielen läßt.In. the drawing is a. Embodiment illustrated. the Line rails. According to this, a1, a2 are each made of a slotted iron ring b1, b2 to yellow. The iron rings can optionally also be subsequently in: a existing system to be attached, so that the increase in self-induction can be achieved without changes to the lines themselves.
