Description
In dem Patent 497 573 ist eine Anordnung zur Signalübertragung auf fahrende Züge
beschrieben, bei der durch Benutzung von Resonanzerscheinungen für Strecken- und
Lokomotivstromkreise und außerdem durch Benutzung einer Differentialschaltung eine
beträchtliche Steigerung der Signalstromwirkung gegenüber früher verwandten Wechselstrominduktionsmethoden
erzielt wird.
Das vorliegende Zusatzpatent hat nun zum Gegenstand eine besondere Differentialschaltung,
bei welcher ein Signalrelais mit zwei Wicklungen benutzt wird, wie es für andere
Signalschaltungen bekanntgeworden ist. Gemaß der Erfindung wird ein solches Relais an
Stelle des Differentialtransformators mittelbar in die von dem Wechselstromerzeuger erregte
Brückenschaltung eingefügt, wobei die eine Wicklung an die Lokomotiv-Resonanzao schaltung, die andere an ihre Ohmsche Nachbildung
angeschaltet ist. Das bedeutet gegenüber den früher genannten Schaltungen eine Vereinfachung und demgemäß eine Verbilligung.
Patent 497 573 describes an arrangement for transmitting signals to moving trains in which, by using resonance phenomena for track and locomotive circuits and also by using a differential circuit, a considerable increase in the signal current effect is achieved over previously used AC induction methods.
The subject of the present additional patent is a special differential circuit in which a signal relay with two windings is used, as has become known for other signal circuits. According to the invention, instead of the differential transformer, such a relay is inserted indirectly into the bridge circuit excited by the alternator, one winding being connected to the locomotive resonance circuit, the other being connected to its ohmic replica. Compared to the circuits mentioned earlier, this means a simplification and, accordingly, a lower cost.
Die Anordnung nach der Erfindung wird nachstehend an Hand der Zeichnung erläutert. The arrangement according to the invention is explained below with reference to the drawing.
Beim Ausführungsbeispiel nach Fig. 1 arbeitet der Wechselstromerzeuger der Lokomotive G über das Signalrelais R auf die Lokomotiv-Resonanzschaltung L, C und deren Ohmsche Nachbildung JV. Die Selbstinduktion L der Resonanzschaltung wird am besten im Fahrgestell der Lokomotive als offener Magnet mit magnetischem Anschluß oder starker Streuung nach dem Gleiskörper angeordnet und an gewissen Stellen des Bahnkörpers der induktiven Wirkung des Strekkenmagneten ausgesetzt. Die Resonanzschaltung kann natürlich auch aus einer Serienschaltung von L und C bestehen.In the embodiment according to FIG. 1, the alternator of the locomotive G works via the signal relay R on the locomotive resonance circuit L, C and its ohmic replica JV. The self-induction L of the resonance circuit is best arranged in the chassis of the locomotive as an open magnet with a magnetic connection or strong scattering after the track structure and exposed to the inductive effect of the track magnet at certain points on the track structure. The resonance circuit can of course also consist of a series circuit of L and C.
Das Signalrelais R ist nun nach der Erfindung als Differentialrelais gebaut, besitzt also zwei Wicklungen, die in der durch die Schaltung skizzierten Weise an die anderen Stromkreisteile der Lokomotive angeschaltet werden. Der Vorteil dieser Schaltung gegenüber dem früher genannten liegt in der Vermeidung eines besonderen Differentialtransformators. The signal relay R is now built according to the invention as a differential relay, so it has two windings that are connected to the other parts of the circuit of the locomotive in the manner outlined by the circuit. The advantage of this circuit over the previously mentioned one lies in the avoidance of a special differential transformer.
Die Selbstinduktion des Signalrelais kann durch Serienschaltung von Kapazitäten (C — vgl. Schaltungsbeispiel 2) zur Erhöhung der Stromsteigerung kompensiert werden. Zur Durchführung des Ruhestromprinzips ist es außerdem zweckmäßig, in die Hauptstromzuführungen des Generators G ein Ruhestromrelais einzuschalten oder den Leitungszustand mittels überlagerten Gleichstromes und Gleichstromrelais zu kontrollieren, wobei der Gleichstrom der Gleichstromdynamo für die Lokomotivbeleuchtung entnommen werden kann.The self-induction of the signal relay can be compensated for by connecting capacitors in series (C - see circuit example 2) to increase the increase in current. To implement the quiescent current principle, it is also useful to switch on a quiescent current relay in the main power supply of the generator G or to check the line status by means of superimposed direct current and direct current relays, whereby the direct current can be taken from the direct current dynamo for the locomotive lighting.
Die Erfindung gilt selbstverständlich für beliebige Signalstromfrequenzen und für Übertragungsmagnete mit und ohne Eisenkern.The invention naturally applies to any signal current frequencies and for Transmission magnets with and without iron core.
