Description

Einrichtung zur Speisung von Weckern oder elektrischen Hörnern aus Starkstromleitungen. Zur Speisung von Weckern oder elektrischen Hörnern aus Starkstromleitungen verwendete man bisher zwischengeschaltete Reduktoren. Am beten als solche geeignet sind Glimmlichtröhren, beispielsweise gewöhnliche Glimmlampen, weil sie auch im Zustande der Stromlosigkeit einen beträchtlichen Teil der Starkstromspannung abdrosseln, so daß an den Weckern oder elektrischen Hörnern keine gefährlichen Spannungen auftreten können. Immerhin beträgt die Restspannung gewöhnlich 4.o bis 5o Volt, so daß an den Unterbrechern Funken auftreten, die Abnutzungserscheinungen verursachen. Kleben die Kontakte (beispielsweise infolge Verstaubung), so brennen die Spulen der Wecker oder elektrischen Hörner meistens durch, weil sie der Belastung mit ununterbrochenem Strom nicht gewachsen sind.Device for feeding alarm clocks or electric horns Power lines. For supplying alarm clocks or electric horns from power lines Intermediate reductors were used up to now. Suitable for praying as such are glow tubes, for example ordinary glow lamps, because they are also im In the absence of current, a considerable part of the high-voltage voltage can be throttled off, so that no dangerous voltages occur on the alarm clocks or electric horns can. After all, the residual voltage is usually 4.o to 5o volts, so on sparks occur in the breakers, which cause signs of wear and tear. Adhere the contacts (e.g. due to dust), the coils of the alarm clock burn or electric horns mostly due to the fact that they are exposed to continuous stress Electricity have not grown.

Gemäß der Erfindung wird diesen Übelständen vorgebeugt, indem der als Reduktor dienenden Glimmlichtröhre ein Kondensator parallel geschaltet und beiden ein (Ohmscher oder induktiver) Widerstand vorgeschaltet wird. Eine solche Anordnung ist an sich bekannt und erzeugt ununterbrochenen Gleichstrom, indem der Kondensator allmählich aufgeladen wird, bis seine Spannung zur 'Zündung der Glimmlichtröhre ausreicht, so daß er sich plötzlich über die Glimmlichtröhre entlädt, worauf dass Spiel von neuem beginnt. Legt man einen Wecker oder ein elektrisches Horn in eine der Verbindungsleitungen zwischen Kondensator und Glimmlichtröhre, so kann man den Unterbrecher kurzschließen, und die obenerwähnten Übelstände können naturgemäß nicht mehr in Erscheinung treten.According to the invention, these inconveniences are prevented by the a condenser connected in parallel with the glow tube serving as a reductor and both an (ohmic or inductive) resistor is connected upstream. Such an arrangement is known per se and generates uninterrupted direct current by the capacitor is gradually charged until its voltage leads to the ignition of the glow tube is sufficient so that it suddenly discharges through the glow tube, whereupon that The game starts all over again. Put an alarm clock or an electric horn into one of the connecting lines between the capacitor and the glow tube, you can use the Short-circuit breakers, and the abovementioned inconveniences naturally cannot appear more.

In der Abb. z ist eine derartige Anordnung dargestellt. Von den Klemmen r, 2, an denen die Starkstromleitung angeschlossen ist, liegt eine Glimmlichtröhre 3 mit vorgeschaltetem Widerstand d. Parallel zur Glimmlichtröhre liegt der Kondensator 5 und in Reihe mit ihm der Wecker 6. Zweckmäßig werden die elektrischen Größen derart abgestimmt, daß die Frequenz in Resonanz mit der Schwingungszahl des Weckers oder des elektrischen Hornes ist.Such an arrangement is shown in Fig. Z. From the clamps r, 2, to which the power line is connected, is a glow tube 3 with an upstream resistor d. The capacitor is parallel to the glow tube 5 and in series with it the alarm clock 6. The electrical quantities are expediently like this matched that the frequency in resonance with the number of vibrations of the alarm clock or of the electric horn is.

Man kann die Spule des Weckers oder des elektrischen Hornes auch als Vorschaltwiderstand für Glimmlichtröhre und Kondensator benutzen, wie dies in Abb. 2 dargestellt ist. Der Strom wird in dem Wecker zwar niemals vollständig unterbrochen, erfährt aber doch taktmäßige Schwankungen der Stärke.The coil of the alarm clock or the electric horn can also be used as a Use a series resistor for the glow tube and capacitor, as shown in Fig. 2 is shown. The current in the alarm clock is never completely interrupted, but experiences rhythmic fluctuations in strength.
