Description

Die Erfindung bezieht sich auf eine Einrichtung zur Signalübertragung von der Strecke auf den fahrenden Zug auf elektrischen Bahnen, die mit Wechselstrom betrieben werden.The invention relates to a device for signal transmission from the Track on the moving train on electric railways that run on alternating current will.

Die Übertragung von der Strecke zur Lokomotive erfolgt in bekannter Weise auf induktivem Wege über Spulerianordnungen, die sich auf der Strecke an den Übertragungsstellen und im Fahrgestell der Lokomotive befinden. Man arbeitet zweckmäßig mit Resonanz des Strecken- und Lokomotivstromkreises. In den Lokomotivstromkreis ist das Signalrelais eingeschaltet, das bei Streckenwirkung anspricht. Es kommt darauf an, daß die Signalfrequenz genügend konstant gehalten wird, was dadurch gewährleistet wird, daß in bekannter Weise die Fahrspannung, deren Frequenz aus Betriebsgründen konstantThe transmission from the track to the locomotive takes place in a known manner by inductive means Paths via bobbin arrangements, which are on the route at the transmission points and are located in the chassis of the locomotive. It is advisable to work with resonance of the track and locomotive circuit. The signal relay in the locomotive circuit is switched on when the line is active appeals to. It is important that the signal frequency is kept sufficiently constant is, which is ensured that in a known manner the driving voltage, the frequency of which is constant for operational reasons

so gehalten werden muß, zur Erzeugung des ,Signalstromes benutzt wird. Diese Erzeugung kann über rotierende oder ruhende Frequenzwandler erfolgen. Die Signalstromerzeugung kann, wie das bei solchen Wechselstrombahnenmust be kept so is used to generate the signal stream. This generation can be done using rotating or static frequency converters. The signal current generation can, like that with such AC railways

as bekannt ist, auf der Strecke erfolgen, wobei an den Übertragungsstellen der Signalstrom auf induktivem Wege auf den Signalstromkreis der Lokomotive übertragen werden kann.as is known to be done on the route, being At the transfer points, the signal current is inductively transferred to the signal circuit the locomotive can be transferred.

Bei einer derartigen Einrichtung besteht der Nachteil, daß der Signalstromkreis der Lokomotive im Ruhezustand nicht dauernd stromdurchfiossen ist, so daß seine Ansprechfähigkeit nicht selbsttätig überwacht wird. Um dieses zu ermöglichen, wird gemäß der Erfindung die Lokomotivanordnung so getroffen, daß der Signalstromkreis dauernd von einem mit dem Signalstrom der Strecke synchron laufenden, auf, der Lokomotive von der Fahrspannung erzeugten Hilfsstrom durchflossen wird. Bei Streckenwirkung an den Übertragungsstellen tritt zu der Wirkung dieses Hilfsstromes die Wirkung des Strekkensignalstromerzeugers hinzu, wodurch in an sich beliebiger Weise die Signalauslösung erfolgt.In such a device there is the disadvantage that the signal circuit of the The locomotive does not have continuous current flowing through it when it is idle, so that its responsiveness is not automatically monitored. In order to make this possible, according to the invention, the locomotive arrangement is made so that the signal circuit is continuously from a running synchronous with the signal stream of the line, on, the locomotive of the auxiliary current generated by the traction voltage flows through it. With line effect on At the transmission points, in addition to the effect of this auxiliary current, there is also the effect of the line signal current generator added, whereby the signal is triggered in any way.

In Abb. ι und 2 ist ein Ausführungsbeispiel für eine Schaltung nach der Erfindung dargestellt. Die Fahrspannung speist einen im Lokomotivkreis L1, C1 liegenden Hilfsgenerator G1. In demselben Kreis liegt das Signalrelais R1, das bei Ansprechen beispielsweise die Bremse B oder eine andere Signaleinrichtung betätigt. L2, C2 ist der Streckenkreis, ■— der über eine Anschlußleitung in Abhängigkeit vom Schalter ί des Signals 6" vom Signalstromerzeuger G2 mit Signalstrom versorgt wird, und zwar ebenfalls von der Fahrspannung über den Transformator T2. Der Lokomotivrulfe'strom wird durch Gegenwirkung des Streckenstromes sich verringern und das Signalrelais R1 zum Ansprechen bringen. Die Verwendung der Resonanz ist jetzt nicht mehr unbedingt erforderlich. Der Synchronismus zwischen Lokomotivhilfsstrom und Streckensignalstrom, der für die WirkungIn Fig. Ι and 2 an embodiment of a circuit according to the invention is shown. The driving voltage feeds a circle lying in the locomotive L 1, C 1 auxiliary generator G. 1 In the same circle is the signal relay R 1 , which actuates, for example, the brake B or another signaling device when responding. L 2 , C 2 is the line circuit, ■ - which is supplied with signal current from the signal current generator G 2 via a connection line depending on the switch ί of the signal 6 ", also from the driving voltage via the transformer T 2 reduce the counteraction of the line current and cause the signal relay R 1 to respond. The use of resonance is no longer absolutely necessary

maßgebend ist, wird durch gemeinsame Erzeugung von der Fahrspannung gewährleistet. In Abb. 3 ist eine andere Schaltungsmöglichkeit wiedergegeben, bei der eine Differentialschaltung des Lokomotivstromkreises gewählt ist. Die Lokomotivübertragungsspule ist mit L1 bezeichnet; mit JV ist ihre das Differentialgleichgewicht herstellende Nachbildung bezeichnet. Das Signalrelais ist alsis decisive, is ensured by joint generation of the driving voltage. In Fig. 3 another circuit option is shown in which a differential circuit of the locomotive circuit is selected. The locomotive transmission coil is labeled L 1; their replica, which produces the differential equilibrium, is designated by JV. The signal relay is available as

ίο Differentialrelais Ra ausgebildet. Die Signalauslösung erfolgt bei Störung des Differentials und evtl. auch beim Verschwinden des von G1 erzeugten Hilfsstromes über ein Ruhestromrelais Rb. Bei Streckenwirkung erfolgt eine Induktion des Signalstromes der Strecke über die Streckenspule L2 in die Lokomotivspule L1 hinein, wodurch das Stromgleichgewicht im Signalrelais RA gestört und die Signalauslösung in Gang .gesetzt wird.ίο Differential relay R a formed. The signal is triggered in the event of a fault in the differential and possibly also when the auxiliary current generated by G 1 disappears via a closed-circuit relay R b . When the line is effective, the line's signal current is induced via the line coil L 2 into the locomotive coil L 1 , which disrupts the current balance in the signal relay RA and sets the signal to be triggered.

Man wird das Ruhestromrelais Rb zweckmäßig als Verzögerungsrelais ausbilden, damit keine Signalauslosung erfolgt, wenn die Fahrspannung auf der Lokomotive infolge kurzzeitigen Ablösens der Schleifbügel von den Fahrdrähten kurzzeitig verschwindet.The closed-circuit relay R b is expediently designed as a delay relay, so that no signal is triggered when the running voltage on the locomotive disappears for a short time as a result of the sliding bracket being briefly detached from the contact wires.
