Description

Vorrichtung zur Überlagerung von tonfrequenten Strömen über bestehende Gleichstrom-und Einphasenwechselstrom-Dreileiteranlagen mit zwei Außenleitern und einem Nulleiter zur Fernsteuerung von Frequenzrelais Es ist bekannt, bestehende Gleichstrom-und Einphasenwechselstrom-Dreileiteranlagen mit zwei Außenleitern und einem Nulleiter durch Aufdrücken von Wechselströmen beliebiger Frequenz auf die Außenleiter oder auch auf den Nulleiter zum Zwecke des Betriebes von Resonanzapparaten zu überlagern. Es sind folgende Anordnungen getroffen worden: i. Überlagerung der beiden Außenleiter derart, daß über den Nulleiter die Summe der in den beiden Außenleitern überlagerten Ströme zurückfließt, oder auch 2. derart, daß im Nulleiter nur die Differenz der beiäen Außenleiterströme auftritt.Device for superimposing audio-frequency currents over existing ones Direct current and single-phase alternating current three-wire systems with two outer conductors and a neutral conductor for remote control of frequency relays It is known, existing Direct current and single-phase alternating current three-wire systems with two outer conductors and a neutral conductor by applying alternating currents of any frequency to the Outer conductor or on the neutral conductor for the purpose of operating resonance apparatus to overlay. The following arrangements have been made: i. Overlay of the two outer conductors in such a way that over the neutral conductor the sum of the two outer conductors superimposed currents flows back, or 2. in such a way that only the Difference between the two external conductor currents occurs.

lin ersteren Falle, in welchem der Nulleiter den doppelten Überlagerungsstrom der Außenleiter zu führen hat, treten wegen der Überlastung des ohnehin schwächer bemessenen Nulleiters sehr hohe Spannungsabfälle auf. Dasselbe ist sinngemäß der Fall, wenn die Überlagerung über den Nulleiter vorgenommen wird. Ferner hat diese Methode den Nachteil, daß zwischen den Außenleitern, zwischen welchen der Anschluß von Resonanzapparaten ebenfalls wünschenswert erscheint, keine Spannung auftritt. Die zweite Anordnung hat den Nachteil, daß zwischen den Außenleitern in der gleichen Weise wie beim Gleichstrom-Dreileitersystem die doppelte überlagerungsspannung auftritt wie zwischen einem Hauptleiter und dem Nulleiter, wodurch die Anwendung von normalen Resonanzapparaten nicht möglich ist.in the former case, in which the neutral conductor has twice the superimposed current the outer conductor has to lead, due to the overload of the already weaker occur dimensioned neutral conductor has very high voltage drops. The same is analogously the Case when the superposition is made via the neutral conductor. Furthermore this has Method has the disadvantage that between the outer conductors, between which the connection of resonance apparatus also appears to be desirable, no tension occurs. The second arrangement has the disadvantage that between the outer conductors in the same How double the superimposed voltage occurs in the direct current three-wire system as between a main conductor and the neutral conductor, eliminating the application of normal Resonance apparatus is not possible.

Die Erfindung hat den Zweck, die Stromverteilung unter Vermeidung obiger Mängel in den drei Leitern gleichmäßig zu gestalten und zu erreichen, daß sowohl zwischen den Außenleitern wie auch zwischen je einem Außenleiter und dem Nulleiter die gleiche Überlagerungsspannung auftritt. Dieser Zweck wird erreicht, dadurch, daß man den bestehenden Gleichstrom- oder Einphasenwechselstrom-Dreileiteranlagen mit zwei Außenleitern und einem Nulleiter Drehstrom mittels Transformatoren überlagert. Die Primärwicklungen können beliebig geschaltet sein.The purpose of the invention is to avoid power distribution to make the above deficiencies in the three ladders evenly and to achieve that both between the outer conductors and between one outer conductor and the Neutral conductor the same overlay voltage occurs. This purpose is achieved by using the existing direct current or single phase alternating current three-wire systems with two outer conductors and a neutral conductor, three-phase current superimposed by means of transformers. The primary windings can be connected as required.

Die Sekundärwicklungen sind in die Leiter der bestehenden Anlage einzuschalten, wobei die bestehenden Generatoren und Batterien der Zentrale als Sternpunkt wirken, da sie praktisch als widerstandslos zu betrachten sind. . Bei Sternschaltung der Primärwicklungen der Aufdrücktransformatoren ist es zweckmäßig, zu Ausgleichszwecken in an sich bekannter Weise eine kurzgeschlossene Dreieckwicklung (Tertiärwicklung) auf den Schenkeln des Drehstromtransformators bzw. der zur Verwendung kommenden drei Einphasentransformatoren anzuordnen, Ferner ist es zweckmäßig, die störenden induktiven Blindströme, welche infolge der starken Vormagnetisierung des Eisenkerns durch die Netzströme entstehen, durch das an sich bekannte Parallelschalten von entsprechend bemessenen Kondensatoren aufzuheben.The secondary windings are to be switched into the conductors of the existing system, where the existing generators and batteries of the control center act as a star point, since they can be regarded as practically without resistance. . With star connection of the primary windings of the push-on transformers, it is useful for compensation purposes a short-circuited triangular winding (tertiary winding) in a manner known per se on the legs of the three-phase transformer or the one to be used to arrange three single-phase transformers, It is also useful to remove the disruptive inductive reactive currents, which result from the strong premagnetization of the iron core arise through the mains currents, through the known parallel connection of appropriately sized capacitors.
