Description

Sperrschaltung für mit tonfrequenter Energie zu Fernsteuerzwecken überlagerte Leitungsnetze Es ist vielfach vorgeschlagen worden, in Starkstromnetze Ströme netzfremder Frequenz einzuführen, um bestimmte Schaltvorgänge auszulösen, z. B. Glühlampen, Tarifapparate u. dgl. aus- und einzuschalten. Bei derartigen Anlagen liegt vielfach die Aufgabe vor, Teile des Netzes, z. B. Stromerzeuger, gegenüber den Überlagerungsströmen abzuriegeln, um mit einer möglichst kleinen überlagerungsenergie auszukommen oder in bestimmten Netzteilen die Auslösung von Schaltvorgängen zu verhindern. Zur Abriegelung bestimmter Netzteile ist bereits vorgeschlagen worden, Gegenspannungen einzuführen, welche die Überlagerungsspannung kompensieren. Dabei zeigt sich die Schwierigkeit, daß bei veränderlicher Belastung des Netzes das Gleichgewicht zwischen der überlagerungsspannung und der Gegenspannung oft gestört wird.Blocking circuit for with audio-frequency energy for remote control purposes Superimposed line networks It has been proposed many times in power networks Introduce currents of non-network frequency in order to trigger certain switching processes, z. B. turn light bulbs, tariff devices and the like off and on. With such systems is often the task of parts of the network, z. B. power generator, opposite to cut off the interference currents in order to use as little interference energy as possible get by or prevent the triggering of switching processes in certain power supplies. Counter voltages have already been proposed to shut off certain power supplies introduce, which compensate the superimposition voltage. This shows the Difficulty that when the network load changes, the balance between the overlay voltage and the counter voltage is often disturbed.

Dieser Übelstand kann gemäß der Erfindung vermieden werden, wenn man die eine Wicklung des -zur Einführung der Gegenspannung dienenden Transformators, dessen andere Wicklung zwischen; dem Ü berlagerungsstromerzeuger und dem gegen die Tonfrequenzströme abzusperrenden Netzteil im Zuge des Netzleiters liegt, über einen den Durchgang der Netzfrequenz sperrenden, für Tonfrequenz durchlässigen Schwingungskreis zwischen die Netzleiter anschließt. Bei der Veränderung der Belastung ändert sich wohl die überlagerungsspannung; da diese Spannung jedoch, unmittelbar auch die Gegenspannung erzeugt, so wird das Gleichgewicht in dem Absperrorgan nicht gestört.This drawback can be avoided according to the invention if one one winding of the transformer used to introduce the counter voltage, its other winding between; the overlay generator and against the Audio frequency currents to be shut off power supply in the course of the power line is via a The resonance circuit that blocks the passage of the mains frequency and is permeable to the audio frequency connects between the line conductors. When changing the load changes probably the overlay voltage; since this tension, however, directly also the counter-tension generated, the equilibrium in the shut-off device is not disturbed.

In der Abbildunz ist ein Ausführungsbeispiel der Schaltanordnung gemäß der Erfindung dargestellt.In the illustration, an exemplary embodiment of the circuit arrangement is shown in FIG of the invention shown.

r ist der Netzstromerzeuger, 2 die Verbraucher. 3 ist ein überlagerungsstromerzeuger, der unter Zwischenschaltung des aus der Reihenschaltung. der Selbstinduktion 4. und der Kapazität 5 bestehenden Schwingungskreises mit den Leitungen 6 und 7 des Netzes verbunden ist. Durch die Kapazität 5 werden die Netzströme vom Schaltstromerzeuger 3 fast ferngehalten; für den überlagerungsstrom ist die Kapazität jedoch, durch die Induktivität ¢ kompensiert. 8 ist ein zur Erzeugung der Gegenspannung dienender Transformator, dessen Primärseite unter Zwischenschaltung der Kapazität 9 und der Induktivität t o mit den Leitungen 6 und 7 des Netzes verbunden ist. Die Kapazität 9 und die Induktivität ro sind auf die überlagerungsfrequenz abgestimmt, so daß sie für diese Frequenz nur einen kleinen Ohmschen Widerstand besitzen, dagegen den Netzstrom kaum hindurchlassen.r is the power generator, 2 the consumer. 3 is a superimposed generator, the with the interposition of the series connection. self-induction 4. and the capacity 5 existing oscillation circuit with the lines 6 and 7 of the Network is connected. Due to the capacity 5, the mains currents from the switching power generator 3 almost kept away; for the overlay current, however, the capacity is through the inductance ¢ compensates. 8 is used to generate the counter voltage Transformer, the primary side of which with the interposition of the capacitance 9 and the Inductance t o is connected to lines 6 and 7 of the network. The capacity 9 and the inductance ro are matched to the superposition frequency, so that they only have a small ohmic resistance for this frequency, but the Barely let mains current through.

Um die durch die Kapazität 9 und die Induktivität to hervorgerufene Phasenverschiebung zwischen der Sekundärspannung des Transformators 8 und der Spannung zwischen den Leitern 6 und 7 auszugleichen, wird zweckmäßig eine Kapazität i i vorgesehen, die im dargestellten Ausführungsbeispiel parallel zur Primärwicklung liegt. Im allgemeinen muß ihre Größe so bemessen werden, daß sie den Magnetisierungsstrom für den Transformator 8 liefert (Resonanz). Wenn es auf eine genaue Kompensation nicht ankommt, kann sie jedoch auch wesentlich kleiner sein. Sie kann auch zur Sekundärwicklung parallel geschaltet werden.To the caused by the capacitance 9 and the inductance to Phase shift between the secondary voltage of the transformer 8 and to balance the voltage between the conductors 6 and 7 is expedient Capacity i i provided, which in the illustrated embodiment parallel to Primary winding is located. In general, their size must be such that they supplies the magnetizing current for the transformer 8 (resonance). When it is on an exact compensation does not matter, it can however also be much smaller be. It can also be connected in parallel to the secondary winding.

Da in der Induktivität i o und der Kapazität 9 ein Spannungsabfall entsteht, so darf im allgemeinen das übersetzungsverhältnis des Transformators nicht i : i sein, sondern die Sekundärspule muß eine etwas höhere Windungszahl besitzen. Zweckmäßig sieht man Anzapfungen vor, mit deren Hilfe die Größe des Übersetzungsverhältnisses eingestellt werden kann. Bei genügend großem übersetzungsverhältnis kann man die Gegenspannung mit Hilfe eines im Primärstromkreis liegenden Widerstandes, insbesondere Ohmschen Widerstandes, einstellen. Damit Phasenabgleichung bei Veränderung des übersetzungsverhältnisses nicht gestört wird, werden die Anzapfstellen vorteilhaft an der Sekundärseite vorgesehen.Since in the inductance i o and the capacitance 9 there is a voltage drop arises, in general the transformation ratio of the transformer must not i: i, but the secondary coil must have a slightly higher number of turns. Expediently, one provides taps with the help of which the size of the transmission ratio can be adjusted. If the gear ratio is large enough, you can use the Counter voltage with the help of a resistor in the primary circuit, in particular Ohmic resistance. This means phase alignment when the transmission ratio changes is not disturbed, the taps are advantageously provided on the secondary side.

Es ist leicht einzusehen, daß an Stelle der in der Abbildung 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 anderen Netzleiter verbunden ist. Zur Absperrung der Netzströme wird auch in diesem Falle vorteilhaft eine auf die Überlagerungsfrequenz abgestimmte Reihenschaltung von Kapazität und Selbstinduktion benutzt.It is easy to see that instead of the 8 designated transformers with two windings also a transformer in the so-called Economy circuit can be used. A choke coil may even be sufficient, whose end adjacent to the line part to be shut off via the mains currents blocking element is connected to the other power line. To shut off the In this case, too, line currents are advantageously applied to the superimposition frequency Matched series connection of capacitance and self-induction used.
