Description
Einrichtung zum Ablösen einer Reif- und Eisschicht durch Wärme an Fahrleitungen elektrischer Triebfahrzeuge, insbesondere Hebezeuge Bei den Fahrleitungen elektrischer Triebfahrzeuge treten im Winter dadurch Schwierigkeiten für den Betrieb auf, daß die Fahrleitungen stark vereisen oder mit Raubreif beschlagen sind. Bei Bahnfahrleitungen, die verhältnismäßig häufig befahren werden, wird durch die Gleitwirkung sowie die Wärmeentwicklung beim Stromübergang der Eisansatz an der Fahrleitung verhindert. Fahrleitungen, die gewisse Zeiten nicht befahren werden, beispielsweise Straßenbahnfahrleitungen in den Nachtstunden, werden. zur Verhinderung des Eisansatzes während dieser Zeit kurzgeschlosisen und mit verminderter Spannung eingeschaltet, so daß infolge des Eigenwiderstandes der Fahrleitung und des hindurchgehenden Stromes eine Wärmeentwicklung eintritt, die den Eisansatz verhindert. Während dieser Zeit kann natürlich die Fahrstrecke nicht befahren werden.Device for removing a layer of frost and ice by means of heat Contact lines for electric traction vehicles, in particular hoists For the contact lines Electric locomotives therefore experience operational difficulties in winter on that the overhead lines are badly iced up or covered with robbery. at Railway contact lines, which are used relatively frequently, is due to the sliding effect as well as the development of heat when the current is transferred, the ice build-up on the contact line prevents. Contact lines that are not used for certain times, for example tram contact lines in the night hours, will. to prevent ice accumulation during this time Kurzgeschlosisen and switched on with reduced voltage, so that as a result of Resistance of the contact line and the current passing through it generates heat occurs, which prevents the formation of ice. During this time, of course, the route can be not be driven on.
Bei den Fahrleitungen für Hebezeuge kann ebenfalls der Fall eintreten, daß ein gewisser Fahrleitungsabs@chnitt eine Zeitlang nicht befahren wird, so d.aß sich Eis und Rau,hreif ansetzen können. Bei diesen Fahrleitungen ist es aber häufig nicht möglich, mit der oben beschriebenen Widerstandsheizung die Fahrleitungen eisfrei zu halten, da ein anderer, nicht abtrennbarer Teil der Leitung in Betrieb ist.In the case of contact lines for hoists, it can also happen that that a certain catenary section is not used for a while, so d.aß ice and rough, ready to put on. However, it is common with these overhead lines not possible, with the resistance heating system described above, the contact lines are free of ice because another, non-separable part of the line is in operation.
Es sind bereits verschiedene Vorschläge bekanntgeworden, die Reifansätze von Fahrleitungen dadurch zu beseitigen, daß die Stromabnehmer selbst beheizt werden. Dabei sind sowohl Anordnungen bekanntgeworden, die eine unmittelbare Erwärmung des Stromabnehmers durch Heizwiderstände bewirken, als auch solche, bei denen die Rolle eines sogenannten Rollenstromabnehmers in einen magnetischen Kreis eingeschaltet und durch Induktionsströme erwärmt wird. Zwar ist es auf diese Weise möglich, den Reifansatz unter dem ruhenden Stromabnehmer zu beseitigen, jedoch ist eine voreilende Erwärmung des Fahrdrahtes zur Beseitigung der Reifansätze eine bestimmte Strecke vor dem Stromabnehmer sehr gering, so daß selbst bei kleinen Stromabnehmergeschwindigkeiten der Stromabnehmerkopf stets auf Teile der Fahrleitung trifft, die noch nicht von Reifanlagerungen befreit sind.Various proposals have already become known, the ripening approaches to eliminate overhead lines by heating the pantographs themselves. Both arrangements have become known that allow immediate heating of the Cause pantograph through heating resistors, as well as those in which the role a so-called roller pantograph switched into a magnetic circuit and is heated by induction currents. It is possible in this way to To eliminate frost build-up under the resting pantograph, however, is a leading one Warming of the contact wire to remove the frost deposits a certain distance very low in front of the pantograph, so that even at low pantograph speeds the pantograph head always encounters parts of the contact line that have not yet been removed from Frost deposits are free.
Deshalb wurde weiter vorgeschlagen, vor dem eigentlichen Stromabnehmer einen besonderen Rauhreifabstreifer anzuordnen, der den Rau ,reif im wesentlichen mechanisch beseitigt und gegebenenfalls noch zusätzlich eine elektrische Heizung enthalten kann, die ihre Wärme durch Kontaktwirkung auf den Fahrdraht übertragen soll. Die mechanische Reifbeseitigung hat jedoch den Nachteil, daß der Fahrdraht erhöhtem Verschleiß unterliegt und d:aß insbesondere an den sogenannten Sonderteilen, wie Weichen, Kreuzungen, Abzweigungsstellen u. dgl., Beschädigungen der Fahrleitung auftreten können. Die Beheizung des mechanischen Rauhreifabstreifers hat bei diesem Vorschlag lediglich den Zweck, die Reif- oder Eiskruste zu lockern, so daß der Verschleiß der Fahrleitung herabgesetzt werden kann.Therefore it was suggested further, in front of the actual pantograph to arrange a special hoarfrost scraper, the rough, ripe essentially mechanically eliminated and, if necessary, an additional electric heater that transfer their heat to the contact wire through contact target. The mechanical frost removal, however, has the disadvantage that the contact wire is subject to increased wear and tear and d: ate especially on the so-called special parts, such as switches, crossings, junctions, etc., damage to the overhead contact line may occur. The heating of the mechanical hoarfrost scraper has on this The only suggestion is to loosen the rime or ice crust, so that the wear and tear the catenary can be lowered.
Die Erfindung beruht auf dem Gedanken, an dem Stromabnehmer ein selbständiges Gerät anzuordnen, das bereits eine gewisse Strecke vor dem Stromabnehmer die Reif- oder Eisschicht beseitigt, ohne durch mechanische Abstreifer die Fahrleitung zu beschädigen.The invention is based on the idea of an independent pantograph To arrange device that already a certain distance in front of the pantograph or ice layer removed without the contact line being closed by mechanical scrapers to damage.
Die Erfindung besteht darin, daß die Stromzuführungseinrichtung zum Fahrzeug mit einem Strahlungsgerät, z. B. einem Wärmestrahler, ausgerüstet ist. Dieser Wärmestrahler wird so angebracht, d.aß die Wärmeenergie bereits eine gewisse Strecke vor dem Stromabnehmer auf die Fahrleitung einwirkt und dadurch Eis- und Rauhreifbesatz beseitigt. Die Wellenlänge dieses Strahlungsgerätes kann beispielsweise im Bereich des Infrarot- oder des Hochfrequenzgebietes oder eines dazwischenliegenden Gebietes liegen.The invention consists in that the power supply device for Vehicle with a radiation device, e.g. B. a radiant heater equipped. This radiant heater is attached in such a way that the thermal energy already has a certain amount Section in front of the pantograph acts on the catenary and thereby ice and Hoarfrost removed. The wavelength of this radiation device can, for example in the range of the infrared or the high frequency range or one in between Area.
