Die Erfindung betrifft eine Schaltungsanordnung zum Betrieb von Vakuumröhren vom Netz aus. Es sind bereits derartige Schaltungen bekannt geworden, bei welchen vom Netz aus eine Spannungsabzweigung über ein Potentiometer vorgenommen wird und die Vakuumröhren an das Potentiometer geschaltet sind. Um eine Übertragung der unvermeidlichen Schwankungen der Netzspan-'nung auf die Vakuumröhren zu vermeiden, hat man dabei Drosselspulen zwischen den Anschlußpunkten des Netzes und dem Potentiometer vorgesehen sowie Kondensatoren zwischen die Anschlußleitungen eingeschaltet.The invention relates to a circuit arrangement for operating vacuum tubes from Power off. Such circuits are already known in which from Network is made from a voltage branch via a potentiometer and the vacuum tubes are connected to the potentiometer. To a transfer of the inevitable To avoid fluctuations in the mains voltage on the vacuum tubes, one has choke coils between the connection points of the network and the potentiometer provided and capacitors switched between the connecting lines.
Im Gegensatz hierzu wird gemäß der Erfindung die Schaltung derart abgeändert, daß die Drosselspulen unter Parallelschaltung von Kondensatoren unmittelbar an die mit der Vakuumröhrenanordnung verbundenen Klemmen gelegt sind. Auf diese Weise wird gegenüber der Anordnung der Drosseln zwischen Netz und Potentiometer der Vorteil erreicht, daß eine erhöhte Sicherheit gegen das Eindringen von SpannungsschwankungenIn contrast, according to the invention, the circuit is modified such that the inductors with parallel connection of capacitors directly to those with the Vacuum tube assembly connected terminals are placed. That way will the advantage over the arrangement of the chokes between the mains and the potentiometer achieved that increased security against the ingress of voltage fluctuations
ag in die Vakuumröhrenanordnung geschaffen wird. Es wird ein Vordringen der Hochfrequenz andererseits nach dem zum abgezweigten, Potentiometerteil parallel geschalteten Kondensator vermieden, der infolgedessen keiner besonderen Sicherung und Bemessung bedarf, sondern durch einen normalen Kondensator gegeben sein kann.ag is created in the vacuum tube assembly. There will be an advance of the high frequency on the other hand after that connected in parallel to the branched off potentiometer part Avoided capacitor, which as a result, no special fuse and rating needs, but can be given by a normal capacitor.
Die Zeichnung zeigt die Neuerung in einem Ausführungsbeispiel. Von den Klemmen i, 2 der Netzspannung ist ein fester oder veränderlicher Widerstand 3 abgezweigt, von welchem die Spannung für die Vakuumröhren nach Art einer Potentiometerschaltung abgegriffen und den Anschlußklemmen 8, 9 für die Röhrenanordnung zugeleitet wird. Parallel zu dem Widerstand 3 und ebenso parallel zu der Spannungsabzweigung 8, 9 ist je ein Kondensator 4 bzw. 5 geschaltet, der den Spannungsschwankungen einen Ausgleich bietet. Unmittelbar vor die Anschlußklemmen 8, 9 der Röhrenanordnung sind Drosselspulen 6, 7 geschaltet, welche entweder Luftdrosseln sein oder Eisen enthalten können.The drawing shows the innovation in an exemplary embodiment. From terminals i, 2 the mains voltage is branched off a fixed or variable resistor 3, from which the voltage for the vacuum tubes is tapped in the manner of a potentiometer circuit and the terminals 8, 9 for the tube arrangement is forwarded. Parallel to the resistor 3 and also parallel to the voltage branch 8, 9 is a capacitor each 4 or 5 switched, which compensates for the voltage fluctuations. Direct choke coils 6, 7 are connected in front of the connection terminals 8, 9 of the tube arrangement, which can either be air chokes or contain iron.
