Description

Anordnung zum Schutz der Stromquelle elektrischer Weichenantriebe gegen Uberstrom bei Stellwerken im Eisenbahn-Sicherungswesen In dem Hauptpatent 8ro997 ist eine Anordnung beschrieben, die bei Eisenbahn-Sicherungseinrichtungen zur Anwendung kommt und bei welcher beim Einstellen einer Fahrstraße die Weichen gruppenweise nacheinander zum Umlaufen gebracht «erden. Im besonderen ist hierbei die Einrichtung so getroffen, daß ein. Überstromausschalter vorgesehen ist, der bei Überlastung anspricht und hierdurch die etwa zu früh eingeschaltete Weichengruppe wieder abschaltet.Arrangement to protect the power source of electrical point machines against overcurrent in signal boxes in the railway security system In the main patent 8ro997 describes an arrangement that is used in railway safety devices is used and in which when setting a route the switches made to circulate in groups one after the other «ground. In particular here is the establishment so made that a. Overcurrent switch is provided, the responds in the event of an overload and thereby the turnout group that is switched on too early turns off again.

Gemäß der Erfindung ist eine solche Einrichtung, d. h. also die Verwendung eines Überstromausschalters besonders zweckmäßig- in: den Fällen, wo bei Netzausfall der Betrieb der Stellwerkseinrichtungen durch ein Reserveaggregat aufrechterhalten wird. An das Reserveaggregat kann man hinsichtlich Belastung nicht so hohe Ansprüche stellen wie an das Netz. Die Zusammenfassung der Weichen zu Gruppen, die sich überlappend umlaufen, muß -daher geändert werden, sobald das Netz ausfällt und der Betrieb mit dem Reserveaggregat bestritten werden muß. Man. könnte nun mit dem Netzüberwach-ungsrelais gleichzeitig die bereits angelaufenen Antriebe abschalten und eine Handstellung der Weichen vornehmen. Dies ist jedoch sehr zeitraubend und umständlich und muß nach Möglichkeit vermieden werden. Hier kennt nun der in dem Hauptpatent bereits verwendete Überstromausschalter eine zweckmäßige Lösung bringen, wenn gemäß der Erfindung die -Anordnung so getroffen wird, daß das Weiterlaufen der bereits bei Netz-. ausfall laufenden: Antriebe durch das Umschalten auf das Reserveaggregat bewerkstelligt wird, wenn. nicht infolge hierdurch, eintretender Überlastung der Überstromausschalter anspricht, d. h. nur in den Fällen, wo zufällig in dem Augenblick des Netzausfalles mehr Weichenantriebe- am Umlaufen sind, als das Reserveaggregat vertragen kann., wird die Abschaltung der angelaufenen Antriebe erfolgen; in allen anderem Fällen dagegen kann ohne Aufenthalt das Weiterlaufen, der Antriebe durch das Reserveaggregat bewirkt werden.According to the invention, such a device, i. H. so the use An overcurrent switch especially useful in: those cases where there is a power failure the operation of the interlocking equipment is maintained by a reserve generator will. The demands on the reserve unit in terms of load are not so high like to the network. The summary of the turnouts into groups that overlap must therefore be changed as soon as the network fails and operations with the reserve unit must be disputed. Man. could now with the network monitoring relay at the same time switch off the already started drives and a manual position of the turnouts. However, this is very time consuming and cumbersome and must if possible be avoided. Here is now the one in the main patent overcurrent switches already used bring an appropriate solution, if according to the invention the arrangement is made so that the continued running of the already at network. Failure running: drives by switching to the reserve unit is accomplished when. not as a result of overloading the Overcurrent switch responds, d. H. only in cases where coincidentally at the moment of the power failure, more point machines are in circulation than the reserve unit the drives that have started will be switched off; in all In other cases, however, the drives can continue to run without stopping the reserve unit can be effected.
