Die Zeichnung zeigt Ausführungsbeispiele der Erfindung in schematischer Darstellung ίο bei Dreiphasennetzen.The drawing shows exemplary embodiments of the invention in a schematic representation ίο with three-phase networks.
Bei der Anordnung nach Abb. ι wird ein Drehstromtransformator verwandt, dessen eine mittels der Leitungen L' an die Maschine angeschlossene Wicklung im Punkte N' in Sternschaltung geschlossen ist, während die andere Wicklung, die mit den Übertragungsleitungen L verbunden ist, im Punkte N" in Sternschaltung zusammengeführt ist. Ein Apparat G, der die Bauart und Wirkungsweise eines beliebigen Senders der drahtlosen Telegraphic oder Telephonie hat, wirkt über die induktive Übertragung S'-S auf den Transformator, wobei die Spule 5* zwichen die Erde und einen der NuIl-In the arrangement according to Fig. Ι a three-phase transformer is used, one winding of which is connected to the machine by means of the lines L ' in a star connection at point N' , while the other winding, which is connected to the transmission lines L , is closed at point N " An apparatus G, which has the design and mode of operation of any wireless telegraphic or telephony transmitter, acts on the transformer via the inductive transmission S'-S , the coil 5 * between earth and one of the
s5 punkte N" oder N' gelegt ist.s5 points N " or N 'is laid.
Die von dem Apparat G ausgesandten Schwingungen werden also über die Leitungen anderen Apparaten G übermittelt, die in ähnlicher Weise mit der Leitung verbunden sind und so eine Nachrichtenübermittlung ermöglichen.The vibrations emitted by the device G are thus transmitted via the lines to other devices G , which are connected in a similar manner to the line and thus enable a message to be transmitted.
Bei der Ausführungsform nach Abb. 2 ist die Spule ,S mit einem Punkt N des Kerns des Transformators verbunden, welcher hier die Rolle der einen Belegung des Kopplungskondensators übernimmt. Im übrigen ist die Anordnung die gleiche wie nach Abb. 1.In the embodiment according to Fig. 2, the coil, S is connected to a point N of the core of the transformer, which here takes on the role of one assignment of the coupling capacitor. Otherwise the arrangement is the same as in Fig. 1.
Zur näheren Erläuterung der Wirkungsweise der Erfindung diene die bekannte Schaltung nach Abb. 3. Hier ist die Spule 6" mit einem Nullpunkt P verbunden, der mittels dreier über drei Kondensatoren K, K' K" geführten Zweigleitungen der drei Phasen der Drehstromleitung L gebildet wird. An die Spule 6" ist induktiv, wie in den anderen beiden Abbildungen dargestellt, der Apparat zum Senden bzw. Empfangen der elektrischen Wellen angeschlossen.To further explain the operation of the invention, the prior art circuit serving as shown in Fig. 3. Here, the coil is 6 "connected to a neutral point P, the means of three over three capacitors K, K 'K" guided branch lines of the three phases of the three-phase line L is formed . As shown in the other two figures, the apparatus for transmitting and receiving the electrical waves is inductively connected to the coil 6 ″.
Die in dieser Schaltung nach Abb. 3 dargestellte kapazitive Ankopplung von Hochfrequenzgeräten an Starkstromleitungen ist, wie gesagt, bekannt, und nur zur Erläuterung der Wirkungsweise des Gegenstandes der Erfindung herangezogen worden.The capacitive coupling of high-frequency devices shown in this circuit according to Fig. 3 on power lines is, as I said, known and only to explain the mode of operation of the object the invention has been used.
Die Einrichtung gemäß der Erfindung ergibt eine störungsfreie Nachrichtenübermittlung mittels Hochfrequenzschwingungen über Kraftübertragungsleitungen ohne die Anwendung besonderer Kopplungskondensatoren. The device according to the invention results in trouble-free communication by means of high-frequency vibrations via power transmission lines without the use of special coupling capacitors.
