Description
Außer der im Eisenbahnwesen allgemein gebräuchlichen Isolierschiene sind auch Einrichtungen, bestehend aus zwei isolierten Schienenteilstrecken, bekannt, die durch den fahrenden Zug irgendeine Sicherheitseinrichtung betätigen. Um die ungewollte, vorübergehende Aufhebung des Kurzschlusses zu vermeiden, sieht die vorliegende Erfindung in Verbindung mit einer zweiteiligen Isolierstrecke ein dazugehöriges Schaltrelais vor, das so eingerichtet ist, daß es nur beim Befahren der beiden isolierten Strecken anzieht, aber beim Befahren nur einer isolierten Strecke nicht abfällt. Auf die Weise wird verhindert, daß eine Isolierschicht auf einer Schiene kein Abfallen des Relais bewirken kann. Dies könnte nur dann eintreten, wenn beide Achsen auf beiden Schienen gleichzeitig auf eine Isolierschicht treffen und an beiden der Übergang verhindert wird. Diese Wahrscheinlichkeit ist aber sehr gering. Außerdem hat diese Isolierstrecke den Vorteil, daß sie nicht durch einen zufälligen Kurzschluß eine Betätigung bewirkt.In addition to the insulating rail commonly used in the railway industry, there are also facilities consisting of two isolated rail sections, known that some safety device by the moving train actuate. To avoid the unintentional, temporary cancellation of the short circuit, sees the present invention in connection with a two-part insulating section an associated switching relay, which is set up so that it is only when driving of the two isolated stretches attracts, but only one isolated when driving Track does not drop. In this way it is prevented that an insulating layer is on a Rail cannot cause the relay to drop out. This could only happen if both axes on both rails hit an insulating layer at the same time and on both the transition is prevented. However, this probability is very low. aside from that this isolating distance has the advantage that it is not caused by an accidental short circuit Actuation causes.
Abb. ι zeigt als Beispiel ein Relais mit zwei Wicklungen 1\ und r2, die an die beiden Hälften I1 und i2 angeschlossen sind. Die Wicklungen sind so bemessen, daß beim Befahren des einen Teiles der isolierten Schiene ein Anziehen des Relaisankers r nicht erfolgt. Erst wenn J1 und i2 kurzgeschlossen sind, zieht das Relais an. Dagegen ist nur eine stromdurchfiossene Wicklung in der Lage, den angezogenen Relaisanker festzuhalten. Damit wird erreicht, daß das Relais auf dem ersten Teil it der isolierten Schiene noch nicht angezogen wird und daher auch eine Aufhebung des Kurzschlusses durch eine isolierende Schmutzschicht nicht wirksam werden kann. Erst wenn I1 und iz kurzgeschlossen werden, zieht das Relais an. Eine dann auftretende Unterbrechung eines Kurzschlusses bleibt wirkungslos, und das Abfallen des Relais erfolgt erst beim Verlassen der letzten Achse von L. Fig. Ι shows as an example a relay with two windings 1 \ and r 2 , which are connected to the two halves I 1 and i 2 . The windings are dimensioned in such a way that the relay armature r does not tighten when driving on one part of the insulated rail. The relay only picks up when J 1 and i 2 are short-circuited. In contrast, only a current-carrying winding is able to hold the attracted relay armature. This ensures that the relay on the first part i t of the insulated rail is not yet picked up and therefore the short circuit cannot be canceled by an insulating layer of dirt. The relay picks up only when I 1 and i z are short-circuited. An interruption of a short circuit that then occurs remains ineffective, and the relay only drops out when the last axis of L is left.

Dadurch wird die Stromaufnahme des Relais so gedrasselt, daß es in gleicher Weise wirkt wie das Relais mit der Doppelwicklung nach Abb. i. Will man die Sicherheit noch etwas weitertreiben, so daß auch auf der Strecke i2 keine falsche Betätigung des Relais möglich ist, so kann man eine Schutzisolier strecke hinter i2 mit einem dritten Widerstand anbringen. As a result, the power consumption of the relay is so throttled that it works in the same way as the relay with the double winding according to Fig. I. If you want to push the security a little further, so that no incorrect operation of the relay is possible on the route i 2 , you can attach a protective insulating route behind i 2 with a third resistor.
