Abstract
Bei dem Verfahren zur Messung der Kontaktkraft zwischen einem Stromabnehmer (3) und einer Stromleitung (2), wird mindestens ein am Stromabnehmer (2) angeordneter Faser-Bragg-Gitter-Sensor (41) unter dem Einfluss der Kontaktkraft mechanisch gedehnt. Ein in den Faser-Bragg-Gitter-Sensor (41) eingespeistes Lichtsignal (LS) wird aufgrund der mechanischen Dehnung in seinem Wellenlängengehalt verändert. Aus der kontaktkraftbedingten Wellenlängenänderung wird mittels Auswertung ein Maß für die Kontaktkraft bestimmt.In the method for measuring the contact force between a pantograph (3) and a power line (2), at least one fiber Bragg grating sensor (41) arranged on the pantograph (2) is mechanically stretched under the influence of the contact force. A light signal (LS) fed into the fiber Bragg grating sensor (41) is changed in its wavelength content due to the mechanical expansion. A measure of the contact force is determined from the change in wavelength caused by the contact force by means of evaluation.
Description
Die Erfindung betrifft ein Verfahren und eine Einrichtung zur Messung der Kontaktkraft zwischen einem Stromabnehmer und einer StromleitungThe invention relates to a method and a device for measuring the contact force between one Pantograph and a power line
Ein Schienentriebfahrzeug wird über eine Stromleitung in Form einer Oberleitung mit elektrischer Energie versorgt. Die Zuführung der Energie erfolgt mittels eines Stromabnehmers (= Pantograph). Hierbei ist ein ausreichender Kontakts zwischen der Stromleitung und dem Stromabnehmer von entscheidender Bedeutung für die Funktionsfähigkeit des Schienentriebfahrzeugs. Die tatsächlich vorhandene Kontaktkraft bestimmt aber auch den Verschleiß und möglicherweise auch die Beschädigung der Stromleitung und des Stromabnehmers. Die Kontaktkraft ist die Kraft, mit der eine Schleifleiste des Stromabnehmers gegen die Oberleitung (= Fahrdraht) gedrückt wird. Eine zu hohe Kontaktkraft sorgt für erhöhten Verschleiß am Fahrdraht und Schleifleiste, eine zu niedrige führt zu einem mangelnden elektrischen Kontakt. Letzteres ist die Ursache für eine Lichtbogenbildung und damit wiederum für erhöhten Verschleiß. Eine korrekt eingestellte Kontaktkraft ist folglich auch von erheblicher wirtschaftlicher Bedeutung.A railcar is powered by a power line supplied with electrical energy in the form of an overhead line. The feed the energy comes from a pantograph. Here there is sufficient contact between the power line and the pantograph is vital for functionality of the railcars. The actual contact force but also determines the wear and possibly also the damage to the Power line and pantograph. The contact force is the force with the one collector bar of the pantograph against the overhead line (= Contact wire) pressed becomes. Too high a contact force increases wear on the contact wire and contact strip, a too low leads to a lack of electrical Contact. The latter is the cause of arcing and with that again for increased Wear. A correctly set contact force is therefore also significant economic importance.

Die Kontaktkraft wird bisher mittels Kraftmessdosen ermittelt. Diese sitzen an den Befestigungspunkten zwischen der Schleifleiste und der Stromabnehmerwippe. üblicherweise ist an jedem Ende der Schleifleiste ein Kraftsensor vorhanden, so dass für eine Wippe mit typischerweise zwei Schleifleisten insgesamt vier Kraftsensoren eingesetzt werden. Die Summe aus den allen vier gemessenen Kräften ergibt die Kontaktkraft.The contact force is so far Load cells determined. These sit at the attachment points between the contact strip and the pantograph head. usually there is a force sensor at each end of the contact strip, so that for one Rocker with typically two contact strips, a total of four force sensors be used. The sum of all four measured forces results the contact force.
Derzeit sind als Kraftsensoren fast ausschließlich elektrische Dehnungsmessstreifen (= DMS) im Einsatz. Die zu messende Kraft wird in einen Verformungskörper eingeleitet, welcher den DMS dehnt. Ungünstig ist allerdings, dass diese Art von Kraftsensor eine elektrische Energieversorgung benötigt. Der gesamte Stromabnehmer inklusive Schleifleiste befindet sich auf Hochspannung, typischerweise zwischen 1,5 kV und 25 kV, bei der Deutschen Bahn insbesondere 15 kV. Das Dehnungsmessstreifen-System ist auf Hochspannungspotential angeordnet und wird beispielsweise mittels Batterie gespeist. Beim Einsatz zweier Motorradbatterien kann man eine Operationsdauer des Systems von etwa 24 Stunden erreichen. Es gibt auch Versuche, die Energieversorgung direkt aus der Oberleitung zu gewinnen. Diese Lösungen sind jedoch sehr aufwändig und störanfällig.Currently, almost as force sensors exclusively electrical strain gauges in use. The one to be measured Force is in a deformation body initiated, which stretches the DMS. However, it is unfavorable that this type of force sensor requires an electrical power supply. The entire pantograph including the contact strip is located on High voltage, typically between 1.5 kV and 25 kV, at the Deutsche Bahn in particular 15 kV. The strain gauge system is arranged at high voltage potential and is, for example powered by battery. When using two motorcycle batteries one can achieve a system operating time of about 24 hours. There are also attempts to supply power directly from the overhead line to win. These solutions are, however, very complex and prone to failure.

Die Erfindung beruht dabei auf der Erkenntnis, dass ein faseroptischer Sensor in Form eines Faser-Bragg-Gitter-Sensors eine deutlich verbesserte Erfassung der Kontaktkraft ermöglicht. Als optischer Sensor benötigt ein Faser-Bragg-Gitter-Sensor keine elektrische Energieversorgung auf Hochspannungspotential. Vielmehr können die Energieversorgung und die Signalauslesung im Innern des Schienentriebfahrzeugs und damit auf Erdpotential erfolgen. Da ein Faser-Bragg-Gitter-Sensor vom Wirkprinzip als optische Dehnungsmessstreifen verstanden werden kann, sind grundsätzlich die gleichen Konstruktionen wie beim Einsatz eines konventionellen elektrischen Dehnungsmessstreifens möglich, allerdings mit dem Vorteil einer intrinsischen Potentialtrennung aufgrund des optischen Wirkprinzips. Der Stromabnehmer, an dem der Faser-Bragg-Gitter-Sensor angeordnet ist, kann also ohne weiteres während des Messvorgangs unter elektrischer (Hoch)Spannung stehen. Andererseits hat ein Faser-Bragg-Gitter-Sensor aber eine ähnliche hohe Empfindlichkeit wie ein elektrischer Dehnungsmessstreifen und benötigt deshalb im Gegensatz zu dem optischen Faserfühlhebel-Sensor kein großvolumiges Federelement.The invention is based on the Realization that a fiber optic sensor in the form of a fiber Bragg grating sensor enables a significantly improved recording of the contact force. Needed as an optical sensor a fiber Bragg grating sensor no electrical power supply at high voltage potential. Rather you can the energy supply and the signal reading inside the railcar and thus take place at earth potential. Because a fiber Bragg grating sensor can be understood from the principle of operation as optical strain gauges can, are fundamentally the same constructions as when using a conventional one electrical strain gauge possible, but with the advantage an intrinsic isolation based on the optical principle. The pantograph on which the fiber Bragg grating sensor is arranged can therefore be without further during of the measuring process are under electrical (high) voltage. on the other hand has a fiber Bragg grating sensor but a similar high sensitivity like an electrical strain gauge and therefore needed in contrast to the optical fiber feeler sensor, not a large one Spring element.
