Description

Elektrische Isolation zwischen einer stromführenden Eisenbahnschiene auf Betonschwellen und der Erde. In der neuzeitlichen Eisenbahnsignaltechnik werden Signale elek- trisch betätigt und Einrichtungen zur Anzeige der Gleisbesetzung elektrisch gesteuert, wobei als übertragungsmittel für den Wirk-oder Steuerstrom auch die Schiene benutzt wird. Da ein störungsfreies Arbeiten der Signalanlage, und der Anzeigeeinrichtungen nur dann gewährleistet ist, wenn der Schwachstrom möglichst verlustlos geleitet wird, ist es erforderlich, die stromführenden Schienenstränge gegeneinander und gegen Erde elektrisch zu isolieren.Electrical isolation between a live Railroad track on concrete sleepers and the earth. In modern railway signaling technology, signals are elec- trically operated and devices for displaying the track occupation electrically controlled, the rail being also used as the transmission means for the active or control current. Since trouble-free operation of the signal system and the display devices is only guaranteed if the weak current is conducted with as little loss as possible, it is necessary to electrically isolate the current-carrying rails from one another and from earth.

Da bei Gleisen mit Betonschwellen hauptsächlich die tief in die Schwellen eingreifenden Befestigungsschrauben der Schienenunterlagerplatten Gefahrenstellenfür das Ableiten des Stromes von der Schiene zum Erdreich ßind, wurde vorgeschlagen, die Schrauben oder die Schraubendübel gegen die Schwellen elektrisch zu isolieren. Since on tracks with concrete sleepers mainly those deep in the sleepers engaging fastening screws of the rail support plates the discharge of the current from the rail to the ground has been proposed, to electrically isolate the screws or the screw anchors from the sleepers.

'Die Maßnahme-Überziehen der Schrauben oder der Schwellenschraubendübel mit Isolierstoff-hat nicht zum Erfolg geführt, weil' der Isoliermantel der Schrauben oft schon beim Einschrauben und der Dübelmanteloftschon nach verhältnismäßig kurzer Zeit infolge der betrieblichen Gleisbeanspruchungen durch Abrieb zerstört wurde.'The measure - covering the screws or the sleeper screw anchors with insulating material - did not lead to success, because' the insulating jacket of the screws often already when screwing in and the dowel jacket often after a relatively short time as a result the operational track stresses destroyed by abrasion became.

Eine dauerhafte und verhältnismäßig billige elektrische Isolation zwischen einer stromführenden Eisenbahnschiene und der Erde ist Gegenstand der Erfindung. Sie sieht vor, daß zwischen der normalen Sohienenunterlagsplatte und der Betonschwelle eine Platte aus solierstoff eingefügt ist, und die Schwellenschraubenlöcher der Unterlagsplatte mit Hülsen aus Isolierstoff ausgefüttert sind die sowohl gegen-den Schraubenschaft als auch in Richtung auf den Schraubenkopf isolieren. Permanent and relatively cheap electrical insulation between a live railroad track and the earth is the subject of the invention. It provides that between the normal shoe pad and the concrete sleeper a plate of insulating material is inserted, and the sleeper screw holes of the The base plate are lined with sleeves made of insulating material the Insulate both against the screw shaft and in the direction of the screw head.

Ein Ausführungsbeispiel der Isolation zwischen einer stromführen- den Schiene und der Erde ist in Abb. 1 dargestellt. . Die stromführende Schiene 1 ist in bekannter Weise auf der Schie- nenunterlagsplatte 2 befestigt. Um die Schiene'gegen Erde 3 elek- trisch zu isolieren, wurde zwischen Unterlagsplatte und Betonschwelle 4 eine Platte aus Isolierstoff 5 eingefügt und die Schwellenschraubenlöcher der Unterlagsplatte mit Flanschhülsen 6 aus Isolierstoff ausgefüttert. Da die zylindrischen Teile der Hülsen gegen die Schäfte der Schrauben 7 und die Hülsenflansche gegen die Federringe 8 und außerdem die Betonschwelle gegen die Schienenunterlagsplatte elektrisch isoliert sind, ist die Gefahr der Ableitung des Stromes von der Schiene zur Erde beseitigt. Schutzanspruch : An embodiment of the isolation between a current-carrying the rail and the earth is shown in Fig. 1. . The current-carrying rail 1 is in a known manner on the rail Nen washer plate 2 attached. Around the rail 'against earth 3 elec- To insulate trisch, a plate made of insulating material 5 was inserted between the base plate and concrete sleeper 4 and the sleeper screw holes of the base plate were lined with flange sleeves 6 made of insulating material. Since the cylindrical parts of the sleeves are electrically isolated from the shafts of the screws 7 and the sleeve flanges from the spring washers 8 and also the concrete sleeper from the rail support plate, the risk of the current being diverted from the rail to earth is eliminated.
