Description
Querdrahtaufhängung für mehrere Fahrleitungen mit Kettenlinienaufhängung einer elektrischen Bahn. Bei den bisher bekannt gewordenen Querdrahtaufhängungen für Fahrleitungen mit Kettenlinienaufhängung bei elektrischen Bahnen sind sämtliche Querdrähte oder zum mindesten ein Teil derselben von dem Masten isoliert, oder es sind die einzelnen Gleisgruppen durch in die Querdrähte eingebaute Isolatoren elektrisch voneinander getrennt. Derartige Anordnungen haben den Nachteil, daß bei Isolatorschäden o. dgl. einzelne Querdrähte Spannung führen können und daß infolgdessen Arbeiter gefährdet wenden, wenn sie beim Auswechseln von Isolatoren oder bei anderen Arbeiten einen spannungführenden Draht berühren. Selbstverständlich kann man durch Erdung der in dem Bereich der Arbeitsstelle befindlichen Drähte Unfälle vermeiden. Derartige Maßnahmen benötigen aber einen Arbeitsaufwand und naturgemäß auch einen Zeitverlust. Gerade der letztere wird häufig dazu führen, daß Arbeiter die Sicherung unterlassen und daß dann Betriebsunfälle auftreten.Cross wire suspension for several contact lines with chain line suspension an electric train. With the previously known cross wire suspensions for contact lines with chain line suspension on electric railways are all Cross wires or at least part of them isolated from the mast, or it the individual track groups are electrical through insulators built into the cross wires separated from each other. Such arrangements have the disadvantage that insulator damage o. The like. Individual cross wires can lead voltage and that as a result workers at risk when changing insulators or doing other work touch a live wire. Of course you can by grounding avoid accidents with the wires in the area of the work site. Such However, measures require a workload and, of course, a loss of time. The latter in particular will often lead to workers failing to secure and that industrial accidents then occur.
Gemäß der Erfindung werden die angegebenen Nachteile dadur rh vermieden, daß sämtliche Querdrähte ahne Einschaltung von Isolatoren unmittelbar rn die Maste geführt sind.According to the invention, the specified disadvantages are avoided dadur rh, that all transverse wires go directly to the masts without the inclusion of insulators are led.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing.
An den Masten a, a sind die Querdrähte b, c, d, e untereinander befestigt. Der oberste Draht b hängt in einer Kettenlinie durch; die unteren Drähte c bis e sind wagerecht geführt. Zwischen den Drähten c und d sind an Flacheisenkonstruktionen f die Isolatoren g, h für die Tragseile i befestigt. Die Stützstreben in zur Festlegung der mittleren Fahrleitungen k, k sind mittels Isolatoren g, h an Flacheisen n angelenkt. (Abb. 2 zeigt die Seitenansicht dieser Teile im doppelten Maßstab der Abb. I). Diese sind an den Querdrähten d und e befestigt. Zur Festlegung der äußeren Fahrleitungen o, o dienen Stützstreben p, p, die in der üblichen Weise an den Masten a gelagert sind.The cross wires b, c, d, e are attached to each other on the masts a, a. The top wire b sags in a chain line; the lower wires c through e are guided horizontally. Between wires c and d are flat iron structures f the insulators g, h for the suspension cables i attached. The support struts in laying down the central contact lines k, k are hinged to flat iron n by means of insulators g, h. (Fig. 2 shows the side view of these parts on a double scale of Fig. I). These are attached to cross wires d and e. To define the outer contact lines o, o serve support struts p, p, which are mounted in the usual way on the masts a are.
Vor den bekannten Anordnungen hat die vorliegende außerdem den Vorzug, daß die Anordnung der Po zellanisolatoren sehr einfach und übersichtlich ist und daß trotzdem jede spannungführende Leitung .doppelt isoliert ist.The present one also has the advantage over the known arrangements that the arrangement of the Po zellanisolatoren is very simple and clear and that every live line is .double insulated.
