Description

Anordnung zur Kompensierung von Spannungsschwankungen. In vielen Fällen erweist es sich als not. Netzspannung konstant zu halten und eintretende Schwankungen durch geeig- nete Vorrichtungen zu kompensieren. Die hierfür üblichen Verfahren reichen für manche Zwecke nicht aus, einerseits, da, sie die Netzspannungsschwankungen nicht genügend kompensieren, anderseits, da sie die Netzspannungsschwankungen nicht schnell genug kompensieren. Diese Mängel beseitigt die vorliegende Anordnung.Arrangement to compensate for voltage fluctuations. In many cases it turns out to be a necessity. Keep the mains voltage constant and occurring fluctuations due to suitable Nete devices to compensate. The methods customary for this are not sufficient for some purposes, on the one hand because they do not sufficiently compensate for the mains voltage fluctuations, and on the other hand because they do not compensate for the mains voltage fluctuations quickly enough. The present arrangement overcomes these shortcomings.

Der eine Zweig der Brückenschaltung, Abb. i, besteht aus einer Drei-Elektrodeni röhre, deren Kathode 2 und Anode i an die Brückenleitungen angelegt sind. Die anderen Brückenzweige bestehen aus Ohmschen Widerständen, die so abgeglichen sind, daß durch die Wicklung 3 normalerweise ein bestimmter Strom fließt. Gitter und Kathode der Röhre q. sind über ein Potentiometer 5 mit den Netzklemmen 6 und 7 verbunden. Der Widerstand der Röhre ist in hohem Maße abhängig von der Spannung, die zwischen Gitter und Kathode liegt. Es ist also klar, daß Netzspannungsschwankungen, die an Gitter und Kathode der Röhre ¢ vom Netz aus herankommen, die Brückeneinstellung verändern und somit den Strom, der durch die Wicklung 3 fließt. Diese Wicklung 3 ist die Wicklung des Feldes einer Zusatzmaschine, die in Serie mit dem Netz liegt. Die Brücke wird so abgeglichen, daß die Netzspannungsschwankungen, die an das Gitter der Röhre q. gelangen, durch den Strom, der durch die Wicklung 3 der Feldmagnete der Zusatzmaschine fließt, genau kompensiert werden. Diese Kompensierung erfolgt momentan beim Eintreten der Spannungsschwankungen.One branch of the bridge circuit, Fig. I, consists of three electrodes tube whose cathode 2 and anode i are connected to the bridge lines. The others Bridge branches consist of ohmic resistances that are balanced so that through the winding 3 normally flows a certain current. Grid and cathode of the Tube q. are connected to the mains terminals 6 and 7 via a potentiometer 5. Of the Resistance of the tube is highly dependent on the voltage applied between grids and cathode lies. It is therefore clear that mains voltage fluctuations that affect grid and cathode of the tube ¢ come from the mains, change the bridge setting and thus the current flowing through the winding 3. This winding 3 is the winding of the field of an additional machine that is in series with the network. The bridge will balanced in such a way that the mains voltage fluctuations which are exerted on the grid of the tube q. get through the current flowing through the winding 3 of the field magnets of the additional machine flows, be precisely compensated. This compensation takes place momentarily when entering of voltage fluctuations.
