Die Erfindung betrifft eine Schaltungsanordnung zum Parallelbetrieb mehrerer Ionenrelais (Quecksilberschaltröhren), die gegenüber den bisher üblichen Schaltungen den Vorteil gesteigerter Betriebssicherheit besitzt. Die bisher üblichen Schaltungen, von denen eine in Abb. 1 dargestellt ist, zeigen den Nachteil, daß sehr oft nur eine einzige Röhre zum Zünden kommt. Dies erhellt aus folgender Betrachtung.The invention relates to a circuit arrangement for operating several ion relays in parallel (Mercury interrupter tubes), which has the advantage of increased operational reliability compared to the conventional circuits. The conventional circuits, one of which is shown in Fig. 1, have the disadvantage that very often only a single tube is ignited. This is evident from the following Consideration.
Die Schaltröhren I und II sind an eine Gleichspannungsquelle G in Parallelschaltung angeschlossen unter Benutzung der Widerstände/^ und R2, die Belastungswiderstände,The interrupters I and II are connected to a DC voltage source G in parallel using the resistors / ^ and R 2 , the load resistors,
z. B. Magnetisierungswicklungen von Hochfrequenzgeneratoren darstellen, und die Vorschaltwiderstände V1 und V2 besitzen. Wie bekannt, werden die Röhren durch einen Induktionsstoß an der Außenelektrode gezündet.z. B. represent magnetizing windings of high-frequency generators, and the ballast resistors V 1 and V 2 have. As is known, the tubes are ignited by an induction pulse on the outer electrode.
Die dazu erforderliche Zündspannung wird durch den ebenfalls von der Röhrengleichspannung betriebenen Zündinduktor Z geliefert. Parallel zu den Belastungswiderständen Hegen die Löschkondensatoren C1 und C2-Diese Kondensatoren werden über einen gemeinsamen Vorsc'haltwiderstand R von einigen 100 Ohm aufgeladeThe ignition voltage required for this is supplied by the ignition inductor Z, which is also operated by the tube DC voltage. Parallel to the load resistors Hegen the quenching capacitors C 1 and C 2 - These capacitors are charged via a common bias resistor R of a few 100 ohms
Es hat sich nun ^eim Betrieb dieser Parallelschaltung herausgestellt, daß häufig nur eine Röhre zündet, während die andere aussetzt. Der Grund dafür liegt darin, daß diejenigen Elektroden, in deren Stromkreise der Belastungswiderstand liegt, also die Anoden der Röhren, nicht nur über die Belastungswiderstände, sondern auch parallel dazu über die Löschkondensatoren miteinander verbunden sind- Diese Kondensatorenverbindung stellt, wenn die beiden Röhren nicht gleichzeitig zünden, für den Zündaugenblick der zweiten Röhre einen Kurzschluß dar, so daßThis parallel connection has now become effective found that often only one tube ignites while the other fails. The reason for this is that those Electrodes in whose circuits the load resistance is located, i.e. the anodes of the tubes, not only through the load resistors, but also through parallel to them the quenching capacitors are connected to each other- These capacitors connection if the two tubes do not ignite at the same time, the second tube is a short circuit, so that
*l Von dem Patentsucher ist als der Erfinder angegeben worden:* l The patent seeker stated as the inventor:

die Lichtbogenspannung der bereits gezündeten Röhre, die etwa 15 bis 20 Volt beträgt, über die Kondensatoren ebenfalls an der Anode der zweiten Röhre liegt und somit das * Anspringen dieser Röhre nicht zustande kommt.the arc voltage of the already ignited tube, which is around 15 to 20 volts, is also connected to the anode of the second tube via the capacitors and thus the * This tube does not jump off.
Erfindungsgemäß wird die Möglichkeit des Spannungsausgleiches zwischen beiden Röhren über die Kondensatoren C1 und C2 dadurch vermieden, daß zu jedem der beiden Kondensatoren, in Reihe mit ihnen geschaltet, eine kleine Luft- oder. Eisendrossel eingeschaltet wird. Diese Anordnung ist beispielsweise in Abb. 2 dargestellt. Die eingeschalteten Drosseln, die diese Abbildung von der Abb. 1 unterscheiden, sind mit D1 und D2 bezeichnet. Die Drosseln sind derart bemessen, daß sie die Löschwirkung der Kondensatoren nicht behindern können. Bei zwei oder einer anderen geraden Anzahl voii parallel arbeitenden Entladungsröhren läßt sich dies dadurch erreichen, daß man die Drosseln induktiv fest koppelt, derart, daß ihre Wirkung für den Löschstrom praktisch zu Null wird. Dies kann z. B. durch Verwendung einer Drossel mit Zapfpunkt in der Mitte erreicht werden. Die Wirkung als Schutidrossel beim Zünden wird dadurch nicht beeinträchtigt. According to the invention, the possibility of voltage equalization between the two tubes via the capacitors C 1 and C 2 is avoided by connecting a small air or air gap to each of the two capacitors in series with them. Iron choke is switched on. This arrangement is shown in Fig. 2, for example. The activated chokes, which distinguish this figure from Fig. 1, are labeled D 1 and D 2. The chokes are dimensioned in such a way that they cannot hinder the extinguishing effect of the capacitors. With two or some other even number of discharge tubes working in parallel, this can be achieved by inductively coupling the chokes so that their effect on the extinguishing current is practically zero. This can e.g. B. can be achieved by using a throttle with a tap in the middle. The effect as a Schutidrossel when igniting is not impaired.
