PATENTAMT.PATENT OFFICE.
Aus Betriebsrücksichten wird der Fahrdraht der elektrischen Bahnen mit .Oberleitungsbetrieb doppelt isolirt, und zwar wird, behufs geringer Belastung der Tragdrähte und auch aus Schönheitsrücksichten, je ein Isolator zwischen Fahrdraht und Tragdraht, bezw. zwischen Tragdraht und Erde geschaltet. Schlägt.bei dieser Anordnung der Isolator zwischen Fahrdraht und Tragdraht durch, so. erhält letzterer die volle Spannung des ersteren, und es werden die Schwachstromanlagen gefährdet, deren die Bahn kreuzende Drähte beim Zerreifsen auf die Tragdrähte fallen können.Out of operational considerations, the contact wire of the electric railways with overhead line operation double insulated, namely, for the sake of less stress on the supporting wires and also for reasons of beauty, an insulator between contact wire and support wire, respectively. connected between suspension wire and earth. Beats. At this Arrangement of the insulator between the contact wire and the support wire, see above. the latter receives the full voltage of the former, and the low-voltage systems are endangered, whose Wires crossing the web can fall onto the supporting wires when they are torn.
Zur Vermeidung dieses Nachtheiles werden gemäfs vorliegender Erfindung die Tragdrähte, welche in bekannter Weise an Isolatoren aufgehängt sind, durch einen die Isolatoren überbrückenden und von der Strafse aus sichtbaren Schmelzstreifen an Erde bezw. die Erdrückleitung angeschlossen.To avoid this disadvantage, according to the present invention, the supporting wires, which are suspended in a known manner on insulators, by a bridging the insulators and from the straits visible melt streaks on earth respectively. the earth return connected.
Hierdurch wird erreicht, dafs ein Kurzschlufs im Isolator zwischen Fahrdraht und Tragdraht
dem Betriebspersonal leicht erkennbar gemacht wird und das Auswechseln des schadhaften
Isolators ohne Zeilverlust möglich ist.
■ In der beiliegenden Zeichnung ist die Erfindung in einem Beispiel zur Darstellung gebracht,
α ist der Fahrdraht einer elektrischen Bahn, welcher mittelst des Isolators b an dem
Tragdraht c aufgehängt ist. d sind die zwischen dem Tragdraht c und dem geerdeten eisernen
Maste e eingeschalteten Isolatoren und/ ist ein Schmelzdraht zur Ueberbrückung eines Isolators
d. This ensures that a short circuit in the insulator between the contact wire and the support wire is made easily recognizable to the operating personnel and the defective insulator can be replaced without any loss of line.
The invention is shown in an example in the accompanying drawing, α is the contact wire of an electrical train, which is suspended from the support wire c by means of the insulator b. d are the insulators connected between the support wire c and the earthed iron mast e and / is a fuse wire for bridging an insulator d.
So lange der Isolator b fehlerfrei bleibt, liegt der Tragdraht an Erde, und Schwachstromdrähte, welche auf letzteren herauffallen, werden ebenfalls geerdet, so dafs jede Gefahr für die zugehörigen Schwachstromanlagen ausge-" schlossen ist. Schlägt der Isolator b durch, so wird durch den nunmehr zur Erde fliefsenden Starkstrom die zugehörige Schmelzsicherung f durchgebrannt und hierdurch das Betriebspersonal veranlafst, den schadhaften Isolator sofort auszuwechseln. In der Zwischenzeit kann aber der Betrieb auf der Bahn aufrecht erhalten werden, da nunmehr der bisher kurz geschlossene Isolator d zur Wirkung kommt.As long as the insulator b remains fault-free, the support wire is connected to earth, and low-current wires that fall onto the latter are also earthed, so that any danger to the associated low-voltage systems is excluded. If the insulator b breaks down, the now the earth fliefsenden power the corresponding fuse f blown, thereby occasioned the operating personnel to replace the defective insulator immediately. In the meantime, the operation can be maintained on the track, because now the previously shorted insulator d comes into effect.
An Stelle der Schmelzsicherungen kann natürlich auch jeder bekannte selbsttätige Maximalausschalter benutzt werden, der dann zweckmäfsig mit einem optischen Signal verbunden wird, welches beim Ausschalten erscheint.Instead of the fuses, of course, any known automatic maximum cut-out switch can also be used be used, which is then appropriately connected to an optical signal which appears when switching off.
