Description
Anordnung zur Unterdrückung des auf die Außenseite des Mantels einer konzentrischen Ultrakurzwellenleitung an einer Unterbrechungsstelle übertretenden Hochfrequenzstromes Es ist oft erwünscht, die auf die Außenseite des Mantels einer konzentrischen Ultrakurzwellenleitung an einer UnterbrechungssteUe übertretenden elektrischen Wellen zu beseitigen. Hierzu verwendet man, -wie an sich bekannt, neuerdings sag. Sperrtöpfe. Diese bestehen aus einem axial den Kabelmantel-umschließenden Zylinder, dessen Länge einem Viertel der zu sperrenden Wellenlänge entspricht und der aneinem Ende kurzgeschlossen ist und an dem anderen Ende einen unendlichen hohen Widerstand darstellt. DieserTopf wird an das Ende oder in den Zug des Kabelmantels verlegt, auf dem man den Hochfrequen7strom unterdrücken will. An Stelle dieses 2/q.-Sperrtopfes kann man Sp:err-ebilde mit konzentrierter Kapazität und Induktivität verwenden, wie es in Abb. i für ein Kabelende gezeigt ist. Der Sperrtopf verhindert hierbei, daß ein Hochfrequenzs.trom auf dem Innenleiter aus dem Kabel herausfließen kann. In dem schräg schraffierten Rauur bildet sich das magnetische und in dem vertil>-al schraffierten das elektrische Feld aus. An den als Kapazitätsbeläge wirkenden Begrenzungsflächen tritt der Widerstand auf, der die Leitung für den Hochfrequenzstrom sperrt.Arrangement for suppressing the on the outside of the jacket one concentric ultra-short wave line crossing at an interruption point It is often desirable to apply high frequency current to the outside of the jacket of a concentric ultra-short wave line at an interruption point crossing Eliminate electrical waves. For this purpose, as is known per se, has recently been used say. Locking pots. These consist of a cylinder axially enclosing the cable jacket, whose length corresponds to a quarter of the wavelength to be blocked and that of one End is short-circuited and at the other end an infinite high resistance represents. This pot is laid at the end of or in the train of the cable jacket, on which one wants to suppress the high-frequency current. Instead of this 2 / q.-locking pot one can use Sp: err-forms with concentrated capacitance and inductance, as shown in Fig. i for one end of the cable. The locking pot prevents that a high-frequency current can flow out of the cable on the inner conductor. In the diagonally hatched area the magnetic forms and in the vertil> -al hatched out the electric field. At the boundary surfaces acting as capacitance coverings the resistance occurs, which blocks the line for the high-frequency current.
Derartige Sperrgebilde nehmen bei Frequenzen im, Meterwellenbereich und darunter große Ausmaße an, so daß ihre Herstell-unb schwierig oder unmöglich wird.Such barrier structures take place at frequencies in the meter wave range and under large dimensions, so that their manufacture is difficult or impossible will.
Die Erfindung betrifft :eine Anordnung zur Unterdrückung des auf die Außenseite des Mantels einer konzentrischen Ultrakurzwellen-Ieitung an einer Unterbrechungsstelle übertretenden Hochfrequenzstromes und besteht darin. daß der Kabelmantel von einer Toroidspul@e umschlossen ist, die mit einer Reihenkapazität auf Resonanz abgestimmt ist. Die Erfindung sei an Hand von Abb.2 erläutert. Die Toroidspu@le S ist um den Kabelmantel L, auf weIchem ein Hochfrequenz.strom gesperrt werden soll, herumgelegt und mit einer Reihenkapazität C auf Resonanz abgestimmt. Eine derartige, auf Resonanz. abgestimmte angekoppelte Toroidspule wirkt wie ein Sperrkreis und bewirkt im, Idealfall ein Verschwinden des auf dem Kabelmantel L sich ausbildenden Stromes.The invention relates to: an arrangement for suppressing the Outside of the jacket of a concentric ultra-short wave line at an interruption point transgressing high-frequency current and consists in it. that the cable sheath of a Toroidspul @ e is enclosed, which is tuned to resonance with a series capacitance is. The invention will be explained with reference to Fig.2. The toroidal coil S is around the Cable sheath L, on which a high-frequency current is to be blocked, laid around and tuned to resonance with a series capacitance C. Such a response. Matched coupled toroidal coil acts like a blocking circuit and, ideally, causes a disappearance of the current developing on the cable sheath L.
Bei abgeschirmten Fernsprechleitungmn ist es bekannt, auf dem Kabelmnantel auftretende, von einer benachbarten Starkstromleitung induzierte Störspannungen durch eine um das Kabel gelegte Ringspule zu -beseitigen, welche mit einem zur Einstellung der richtigen Phasenbeziehung,-en dienenden Kondensator verbunden ist. Demgegenüber bezieht sich die vorliegende Erfindung, wie bereits erwähnt. auf Anordnungen zur Unterdrückung des auf die Außenseite des Mantels einer konzentrischen Ultrakurzwellenleitung an einer Unterbrechungsstelle übertretenden Hochfrequenzstromes.In the case of shielded telephone lines, it is known that on the cable jacket Occurring interference voltages induced by a neighboring power line by means of a toroidal coil placed around the cable, which can be adjusted with a the correct phase relationship, -en serving capacitor is connected. In contrast the present invention relates as mentioned earlier. on orders to Suppression of the on the outside of the cladding of a concentric ultra-short wave line high-frequency current passing at an interruption point.
