Description
Isolierung für gebogene starre Leiter Elektrische Leiter, z. B. solche, die in Transformatoren zur Verbindung von -Wicklungsteilen benutzt werden, isoliert man häufig durch übergeschobene Rohre aus Papier, Porzellan oder irgendeinem anderen Isolierstoff. Da diese Stoffe, zumal solche, die unter Öl benutzt werden, meist nicht ein nachträgliches Biegen der daraus hergestellten Rohre und auch nur die Herstellung gerader Rohre gestatten, kann man auf diese Weise nur gerade Leiter isolieren.Insulation for curved rigid conductors Electrical conductors, e.g. B. those used in transformers to connect winding parts, isolated often through tubes made of paper, porcelain or some other material Insulating material. Because these substances, especially those that are used under oil, mostly not a subsequent bending of the pipes made from it and even just the To allow the production of straight pipes, you can only use straight conductors in this way isolate.
Nach der Erfindung benutzt man zur Isolierung gebogener starrer Leiter starre Rohrstücke von einer durch den Krümmungsradius des Leiters bestimmten Länge und schräger Schnittfläche, die hintereinander auf den Leiter aufgefädelt und in mehreren Lagen so angeordnet sind, daß die Rohre einer Lage immer die Stoßstellen zwischen den Rohren der benachbarten Lagen überdecken. Auf diese Weise erhält man eine sichere Isolation mit guter Durchschlagfestigkeit und großen Kriechwegen.According to the invention, bent rigid conductors are used for insulation rigid pipe sections of a length determined by the radius of curvature of the conductor and inclined cut surface, which are threaded one behind the other on the conductor and in several layers are arranged so that the pipes of one layer always meet the joints cover between the tubes of the adjacent layers. That way you get a safe insulation with good dielectric strength and large creepage distances.
In der Zeichnung ist ein Ausführungsbeispiel dargestellt. Der Leiter a ist auf seinem geraden Teil durch zwei übergeschobene konzentrische Rohre b geschützt. Auf den gebogenen Teil ist zunächst eine Anzahl von Rohrstücken c aufgereiht, die allein nur einen unvollkommenen Schutz ergeben, weil die Stoßstellen zwischen ihnen leicht durchschlagen werden können. Darum ist über diese Rohrstücke c eine zweite Lage von Rohrstücken d geschoben, die so bemessen und angeordnet sind, daß sie die Stoßstellen der ersten Lage überdecken. Zur weiteren Erhöhung der Sicherheit kann man nun über diese Lage noch eine oder mehrere Lagen e schieben, die immer so liegen, daß die Stoßstellen der vorhergehenden Lage überdeckt sind.An exemplary embodiment is shown in the drawing. The head a is protected on its straight part by two concentric tubes b pushed over. First a number of pipe pieces c is lined up on the bent part, the only result in imperfect protection because the joints between them can be easily penetrated. This is why there is a second piece of pipe c over this Position of pipe pieces d pushed, which are dimensioned and arranged so that they the Cover the joints of the first layer. To further increase security can you now slide one or more layers e over this layer, which always lie like this that the joints of the previous layer are covered.
Die .letzten Rohre der äußersten Lage werden durch Bände, die auf das äußerste gerade Rohr aufgewickelt oder aufgepreßt sind, gegen Längsverschiebung gesichert.The last tubes of the outermost layer are supported by volumes that go up the outermost straight pipe are wound or pressed against longitudinal displacement secured.
