Besondere Probleme bestehen bekanntlich bei Isolatoren im Schienenverkehrsweßen. l3ei den üblichen hierfUr bisher eingesetzten Isolatoren aus Porzellan, Keramik oder Glas ist einmal die rationelle Herstellung von spannungsfreien Isolatorkörper recht schwierig und zum anderen sind alle diese Materialien eehr bruchanfällig. Die geschilderten wirtschaftlichen und technischen Gesichtspunkte spielen bei Isolatoren die dies Oberleitungen von Schienenfahrzeugen eine besondere Rolle.As is known, there are particular problems with insulators in the railways. In the case of the usual insulators made of porcelain and ceramics that have been used for this up to now or glass is the efficient production of stress-free insulator bodies quite difficult and on the other hand all these materials are very prone to breakage. The described economic and technical aspects play a role in isolators which this overhead lines of rail vehicles play a special role.
Wegen der benötigten hohen Stückzahlen ist eine wirtschaftliche Fertigung besonders wichtig. Weil die Isolatoren im Gebrauch sehr stark mechanisch beansprucht werden, ist auch eine verminderte Bruchanfälligkeit von erheblichem Vorteil. Die Bruchsicherheit ist einmal erforderlich, damit die Isolatoren beim Transport und bei der Montage nicht schon beschädigt werden, zum anderen können bei höheren Geschwindigkeiten der Schienenfahrzeuge durch die dabei auftretenden mechanischen Schwingen der Fahrdrähte zu spröde Isolatoren reißen.Because of the high number of pieces required, it is economical to manufacture particularly important. Because the isolators are in use a lot strong mechanical are stressed, a reduced susceptibility to breakage is also significant Advantage. The break resistance is required once so that the insulators when Transport and during assembly are not already damaged, on the other hand at higher speeds of the rail vehicles due to the resulting mechanical oscillations of the contact wires tear into brittle insulators.
Gegenstand der Erfindung sind Isolatoren für Fahrzeuge, Hebe- und Fördermittel die zwecks Fortbewegung und/oder Betrieb elektrische Energie von einem Netz Uber Schleifkontakte abnehmen, bzw. solche Isolator.The invention relates to insulators for vehicles, lifting and Funding for the purpose of locomotion and / or operation of electrical energy from a Remove the network via sliding contacts or such an insulator.
teile, die die charakteristischen elektrischen Eigenschaften des Isolators bestimmen. In Betracht kommen vor allem Isolatorteile, die bisher aus sehr sprödem Material wie Porzellan, Keramik oder Glas bestanden. Für die Isolatoren bzw. die vorgenannten Teile davon werden Formosßson verwendet, wie sie im Hauptpatent beschieben sind. Dies hat den Vorteil, daß diese Kunststoff-Formteile in günstigen Taktzeiten im Preß-, Sprltzpre8- und Spritzgießverfahren gegebenenfalls auch vollautomatisch, hergestellt werden können.parts showing the characteristic electrical properties of the insulator determine. Particularly into consideration are insulator parts that have hitherto been made of very brittle Material like porcelain, ceramic or glass passed. For the isolators or the Afore-mentioned parts thereof are Formosßson used as they are described in the main patent are. This has the advantage that these plastic molded parts can be used in favorable cycle times in compression, spray molding and injection molding processes, if necessary also fully automatically, can be produced.
Wenngleich die erfinduggsgemäßen Isolatoren bzw. Isolatorteile aus den vorgenannten Gründen besonders für das Schienenverkehrswesen und hier vor allem fur die Isolatoren an den Fahrleitungen von ganz besonderer Bedeutung sind, eignen sie sich auch fUr andere Fahrzeuge, Hebe- und Fördermittel, wie Oberleitungsbuse, Krähe, Auf zUge usw. Vor allem kommen Isolatorschirme in Betracht, z. B. solche, die auf stab- oder rohrförmige Kerne aus an eich bekanntem glasfrverstärktem Duroplastkunststoff, z. B. ungesättigten Polyestern, aufgebracht sind. Dieser Kern soll die erforderliche Zugfestigkeit besitzen, während der oder die Isolatorschirme die wesentlichen elektrischen Eigenschaften bestimnn.Although the isolators or isolator parts according to the invention are made the aforementioned reasons especially for the rail transport sector and here above all for the insulators on the contact lines are of particular importance they are also suitable for other vehicles, lifting and conveying equipment, such as trolleybuses, Crows, lifts, etc. Above all, isolator screens come into consideration, z. B. those which are based on rod-shaped or tubular cores made of glass-FR-reinforced thermoset plastic known from calibration, z. B. unsaturated polyesters are applied. This core aims to provide the required Have tensile strength, while the insulator screen or screens is the essential electrical Determine properties
Die Schirme können dabei einzeln oder in Form einer von vonherein hergestellten Kombination mehrerer Schirme auf den Stab aufgebracht werden.The screens can be used individually or in the form of one produced combination of several screens are applied to the rod.
Eine Ausführungsform stellt einen Hängeisolator dar, der einen glasfaservarstärkten Kern besitzt, auf dem sich die Isolatorschirme aus den Fornmosen nach den Anspruche 1 bis 6 des Hauptpatents befinden, wobei die Aufhängung so konstruiert ist, daß der glasfaserverstärkte Kern an den Enden konisch erweitert ist und daß diese Erweiterung von Je einer mit einer entsprechenden konischen Aussparung versehenen Kappe erfaßt wird, die die Aufhängeöse trägt.One embodiment is a suspension insulator that has a fiberglass reinforced Has core on which the isolator screens from the Fornmosen according to the claims 1 to 6 of the main patent are located, the suspension being constructed so that the fiberglass-reinforced core is flared at the ends and that this expansion each covered by a cap provided with a corresponding conical recess that carries the hanging loop.
Die Isolatoren bzw. Isolatorteile können auch noch lackiert sein.The insulators or insulator parts can also be painted.
Diese Lackierung braucht die elektrischen Eigenschaften nicht zu verbessern, sondern 8011 diese lediglich nicht beeinträchtigen, d. h., sie soll gegen etwa auftretende Kriechetröme oder Lichtbögen entweder beständig sein oder an den beanspruchten Stellen so wegbrennen, daß keine leitfähige Spur zurUckbleibt. Die Lackierung hat die Aufgabe, die Isolatoren bzw. Isolatorteile gegen Witterungseinflüsse zu schUtzen. Als Lackierung ist z. B.This paint does not need to improve the electrical properties, but only 8011 do not affect this, d. i.e., it should be used against any occurring Creeping currents or arcs either be permanent or at the stressed points Burn away so that no conductive trace remains.
