   Es ist leicht einzusehen, dass an Stelle der in der Figur mit 8 bezeichneten Transformatoren mit zwei Wicklungen auch ein Transformator in der sogenannten Sparschaltung verwendet werden kann. Unter Umständen genügt sogar eine Drosselspule, deren, dem abzusperrenden Leitungsteil benachbartes Ende über ein die Netzströme absperrendes Glied mit dem andern Netzleiter verbunden ist. Zur Absperrung der Netzströme wird auch in diesem Falle vorteilhaft eine auf die Überlagerungsfrequenz abgestimmte Reihenschaltung von Kapazität und Selbstinduktion benutzt. 



   PATENT-ANSPRÜCHE :
1. Sperrschaltung für Leitungsnetz, in die Energie netzfremder Frequenz eingeführt wird, bei der zwischen dem Überlagerungsstromerzeuger und dem abzusperrenden Teil der Leitung eine Gegenspannung eingeführt wird, dadurch gekennzeichnet, dass der im Zuge der Leitung liegende zur Einführung der Gegenspannung dienende Transformator   (8)   oder Spule unter Zwischenschaltung eines die Netzströme schwächenden, auf die Überlagerungsfrequenz abgestimmten Schwingungskreises   (9,   10) unmittelbar mit den Leitungen (6, 7) des Netzes verbunden ist.

   It is easy to see that instead of the transformers denoted by 8 in the figure with two windings, a transformer in the so-called economy circuit can also be used. Under certain circumstances, even a choke coil is sufficient, the end of which, adjacent to the line part to be shut off, is connected to the other line conductor via a member that shuts off the mains currents. In this case, too, a series connection of capacitance and self-induction that is matched to the superimposition frequency is advantageously used to shut off the mains currents.



   PATENT CLAIMS:
1. Blocking circuit for the line network, into which energy of a frequency external to the network is introduced, in which a counter voltage is introduced between the superimposed current generator and the part of the line to be shut off, characterized in that the transformer (8) or transformer located in the course of the line is used to introduce the counter voltage Coil is connected directly to the lines (6, 7) of the network with the interposition of an oscillating circuit (9, 10) which weakens the network currents and is tuned to the superimposition frequency.
