Description

Einrichtung an Schallsenderanlagen. Das Patent 3q.8=27 betrifft eine Einrichtung für mit Wechselstrom betriebene Schallsenderanlagen, bei welcher der den Sender enthaltende, von einer Wechselstrommaschine gespeiste Wechselstromkreis durch Einschaltung eines der Größe der Selbstinduktion des Senders entsprechenden Kondensators auf die Betriebsfrequenz abgestimmt ist. Erfolgt die Einschaltung des Kondensators wie bei dem in dem Hauptpatent dargestellten Beispiel in Reihe mit der Maschine und dem Schallsender, so ergeben sich, da der Fall der Spannungsresonanz vorliegt, am Kondensator und an der Wechselstromwicklung des Senders unter Umständen sehr hohe Spannungen. Vorteilhafter ist der in dem Hauptpatent nicht gezeichnete Fall der Stromresonanz, d. h. die Einschaltung des Kondensators parallel zur Senderwicklung, weil sich alsdann überall nur höchstens die Klemmenspannung der Maschine ergibt. Bei diesem Fall kann es jedoch vorkommen, daß der durch den parallel geschalteten Kondensator und die Maschine gebildete Stromkreis mit den höheren Harmonischen der Maschine in Resonanz gerät, so daß sich in dem durch die Maschine und den Kondensator dargestellten Stromkreis ein sehr hoher Stromverbrauch und eine entsprechende hohe Belastung der Maschine einstellt, wodurch wiederum der durch den Phasenabgleich erzielte Vorteil der Verkleinerung der Maschine aufgehoben wird. Die Erfindung bezieht sich auf diesen letztgenannten Fall. Sie besteht darin, daß durch Einschaltung einer Selbstinduktion (Drosselspule) in dem von der Maschine und dem Kondensator gebildeten Kreis dieser Kreis gegen die auftretenden höheren Harmonischen verstimmt wird; dadurch findet eine Abdrosselung dieser Schwingungen statt. Die Einschaltung der Selbstinduktion kann entweder in dem gemeinsamen Stromkreise oder auch in der den Kondensator enthaltenden Brücke erfolgen.Installation on sound transmitter systems. The patent 3q.8 = 27 concerns one Device for sound transmitter systems operated with alternating current, in which the AC circuit containing the transmitter and powered by an alternator by switching on one corresponding to the size of the self-induction of the transmitter Capacitor is matched to the operating frequency. If the Capacitor as in the example shown in the main patent in series with of the machine and the sound transmitter, there is the case of voltage resonance present, on the capacitor and on the alternating current winding of the transmitter under certain circumstances very high voltages. The one not shown in the main patent is more advantageous Case of current resonance, d. H. the connection of the capacitor parallel to the transmitter winding, because then only the terminal voltage of the machine results everywhere. In this case, however, it can happen that the parallel-connected Capacitor and the machine formed circuit with the higher harmonics of the Machine gets into resonance, so that it is caused by the machine and the capacitor shown circuit has a very high power consumption and a correspondingly high Load of the machine adjusts, which in turn results from the phase adjustment The advantage achieved by downsizing the machine is canceled. The invention relates refer to this latter case. It consists in the fact that by engaging a Self-induction (choke coil) in that formed by the machine and the capacitor Circle this circle is detuned against the occurring higher harmonics; through this a throttling of these vibrations takes place. The activation of self-induction can either be in the common circuit or in the circuit containing the capacitor Bridge take place.

In der Zeichnung sind beide Fälle in Gestalt schematischer Schaltskizzen wiedergegeben, und zwar zeigt Abb. Z die Drosselspule im Hauptstromkreis zwischen Maschine und Kondensator, während sie bei Abb. 2 in der den Kondensator enthaltenden Brücke liegt.In the drawing, both cases are in the form of schematic circuit diagrams reproduced, namely Fig. Z shows the reactor in the main circuit between Machine and condenser, while in Fig. 2 they contain the condenser Bridge lies.

Es bezeichnet M eine Wechselstrommaschine, S einen Schallsender, K den Kondensator und D die Drosselspule.It denotes M an alternating current machine, S a sound transmitter, K the capacitor and D the choke coil.
