Description

Durchführungen für sehr hohe Spannungen, insbesondere Kondensatordurchführungen, werden in bekannter Weise aus in Öl gekochtem Papier o. dgl. gewickelt und zum Schutz gegen Feuchtigkeit in eine Hülse, z. B. aus Hartpapier, fest eingesetzt, die an den Enden der Durchführung den Wickelkörper etwas überragt. Mit zunehmender Spannung erhalten die Durchführungen eine Länge, die «° schwierig herzustellen ist, da die Breite des auf dem Markt erhältlichen Papiers begrenzt ist. Um Durchführungen der erforderlichen Länge herzustellen, muß das verwendete Papier aus mehreren Breiten zusammengesetzt werden. Bei einfachem Wickeln aneinandergesetzter Papierbahnen entsteht eine durchgehende Stoßfuge, die keine genügende Isolierfähigkeit besitzt. Man hat diese, durchgehende Stoßfuge dadurch vermieden, daßBushings for very high voltages, in particular condenser bushings are made in a known manner from boiled in oil Paper o. The like. Wrapped and to protect against moisture in a sleeve, z. B. off Hard paper, firmly inserted, the winding body slightly at the ends of the implementation towers. As the voltage increases, the length of the bushings is difficult to manufacture because the width of the paper available on the market is limited. To carry out the required To produce length, the paper used must be composed of several widths will. Simply winding paper webs that are attached to one another creates a continuous one Butt joint that does not have sufficient insulation properties. You have this, continuous Butt joint avoided that

ao man die Papierbahnen überlappt und vor dem Aufwickeln die Überlappungsstelle aufgeschnitten hat, wobei der Schnitt nicht senkrecht zur Wickelachse abläuft, sondern sich ständig verschiebt. Man hat auch sich überläppende Papierbahnen kurz vor dem Wikkeln in der Überlappungsstelle aufgeschnitten. Ferner hat man die Stoßfugen der Papierbahnen auf der Länge der Durchführung versetzt. ao you overlap the paper webs and cut open the overlap before winding has, whereby the cut is not perpendicular to the winding axis, but is constantly shifting. One also has overlapping Paper webs cut open at the point of overlap shortly before winding. Furthermore, the butt joints of the paper webs have been offset along the length of the bushing.

Alle diese Ausführungen besitzen aber bei Kondensatordurchführungen den Nachteil, daß die durch die Stoßfugen herbeigeführten geschwächten Stellen des Isoliermaterials mit Hilfe der Metalleinlagen der Durchführung in Reihe geschaltet sind. Dies ist auch dann der Fall, wenn die Metalleinlagen über die Klemme versetzt gegeneinander verteilt sind.However, all these designs have the disadvantage of condenser bushings that the weakened areas of the insulating material brought about by the butt joints Using the metal inserts of the implementation are connected in series. This is also then the case when the metal inserts are offset from one another via the clamp.

Gemäß der Erfindung wird dieser MangelAccording to the invention, this shortcoming becomes

dadurch beseitigt, daß die Stoßfugen der Papierbahnen in bezug auf die gestaffelt gegeneinander versetzten, sich überlappenden Metalleinlagen so gruppiert werden, daß eine Reihenschaltung der schwachen Stellen des-Isoliermaterials vermieden ist, und zwar geschieht dies dadurch, daß die Stoßfugen der Papierbahnen außerhalb der durch die Metalleinlagen gebildeten Staffeln liegen und daß radial durch den ganzen Wickelkörper gehende Stoßfugen vermieden sind.thereby eliminating that the butt joints of the paper webs with respect to the staggered against each other offset, overlapping metal inlays are grouped so that a series connection of the weak points of the insulating material is avoided, and this is done by the fact that the butt joints of the paper webs outside by the metal inserts formed staggered and that radially extending through the entire winding body butt joints are avoided.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt. α ist der durchgeführte Leiter, b der Wickelkörper der Durchführung, der aus aneinanderstoßenden Papierbahnen mit den Metalleinlagen d gewickelt ist, und c ist der Befestigungsflansch. Die Stoßfugen ex bis es, ft und f2 der Papierbahnen sind in bezug auf die gestaffelten und sich überlappenden Metalleinlagen d so gruppiert, daß eine Reihenschaltung der Stoßfugen durch die Metalleinlagen verhindert ist.An exemplary embodiment of the invention is shown schematically in the drawing. α is the conductor passed through, b the winding body of the bushing, which is wound from abutting paper webs with the metal inserts d, and c is the fastening flange. The butt joints e x to e s , f t and f 2 of the paper webs are grouped with respect to the staggered and overlapping metal inserts d that a series connection of the butt joints through the metal inserts is prevented.
