Description

Elektrische Beheizung von Stromabnehmer-Kontaktstücken Die elektrische Beheizung von Stromahnehmerkontaktstücken als Vorbeugungsmittel gegen schädliche Einwirkungen von Rauhreifansatz ist bekannt. Im Gegensatz zu den bekannten Einrichtungen dieser Art erfolgt erfindungsgemäß die Erwärmung des Kontaktstückes durch Induktionsströme, indem das Kontaktstück in einen magnetischen Kreis eingeschaltet ist, der von einer stromdurchflossenen Spule erzeugt wird. Eine derartige Beheizung des Stromahnehmerkontaktstückes ermöglicht einen besonders einfachen Zusammenhau der Heizeinrichtung mit dem zu beheizenden Kontaktstück. Es kann nämlich der Spulenkern im magnetischen Kreis das eine Joch eines - Transformatorkerns sein, während das andere Joch das zu erwärmende Kontaktstück trägt. Ist das Kontaktstück eine Rolle, so bildet zweckmäßigerweise die Rollenachse das eine Joch des Transformatorkerns der Spule. Ein derartiges Ausführungsbeispiel für die Erfindung ist in der Fig. i und 2 der Zeichnung schematisch dargestellt, und zwar in zwei verschiedenen Ansichten und zum Teil im Schnitt.Electrical heating of current collector contacts The electrical Heating of current sensor contact pieces as a preventive against harmful The effects of hoarfrost deposits are known. In contrast to the well-known facilities According to the invention, this type of heating of the contact piece takes place by induction currents, by switching the contact piece into a magnetic circuit that is controlled by a current-carrying coil is generated. Such a heating of the current sensor contact piece enables a particularly simple combination of the heating device with the to heating contact piece. The coil core in the magnetic circuit can do that one yoke of a transformer core, while the other yoke is the one to be heated Contact piece carries. If the contact piece is a role, it expediently forms the roller axis is one yoke of the transformer core of the coil. Such an embodiment for the invention is shown schematically in Figs. i and 2 of the drawing, in two different views and partly in section.

i ist die Kontaktrolle und :2 die Kontaktleitung. Die Rollenachse 3, die mit dem Rollenträger 4. verbunden ist, bildet das eine Joch eines Transformatorkerns 5, der auf dem anderen Joch eine Spule 6 trägt. Die Rollenachse 3 ist durch einen Bügel 7 auf dem Eisenkern 5 befestigt.i is the contact role and: 2 the contact line. The roller axis 3, which is connected to the roller carrier 4, forms one yoke of a transformer core 5, which carries a coil 6 on the other yoke. The roller axis 3 is through a Bracket 7 attached to the iron core 5.

Der Spulenkern und die beiden Seitenstücke des Transformatorkerns 5 bestehen aus geblättertem Eisen, um die Erwärmung in der Nähe der Spule möglichst klein zu halten. Die Rollenachse 3 als Joch ist mit vollem Ouerschnitt ausgeführt, da die darin erzeugte Wärme in die Kontakterolle fließen soll.The coil core and the two side pieces of the transformer core 5 are made of peeled iron to keep the heating near the coil as possible to keep it small. The roller axis 3 as a yoke is designed with a full cross section, because the heat generated in it should flow into the contact roller.

Sind mehrere Kontaktleitungen mit je einer oder mehreren Kontaktrollen vorhanden, so kann jede Kontaktrolle für sich nach Bedarf durch Einschalten der zugehörigen Spule in den diese speisenden Stromkreis erwärmt «erden.Are several contact lines each with one or more contact roles available, each contact role can be switched on as required by switching on the associated coil in the circuit that feeds it.
