Description

Elektrischer Leiter zum Wickeln von Spulen Die Erfindung hetri -fft einen elektrischen Leiter zum Wickeln von Spulen, der aus einer Folie besteht, die auf ein Isolierband aufgespritzt ist, und besteht darin, daß die über die Folie überstehenden Ränder des Isolierbandes um die Folie herumgeschlungen sind.Electrical conductor for winding coils The invention hetri -fft an electrical conductor for winding coils, which consists of a film which is sprayed onto an electrical tape, and consists of that over the foil protruding edges of the insulating tape are wrapped around the film.

Elektrische Leiter, die aus einer auf Isolierband aufgespritzten Folie bestehen, sind bereits bekannt; sie sind jedoch den mechanischen Bieänspruchungen beim Wickeln von Spulen nicht gewachsen. Durch das Herumschlagen der über die Folie überstehenden Ränder des Isolierbandes um die Folie wird dieser Nachteil beseitigt und gleichzeitig auch der weitere Vorteil einer größeren dielektrischen Festigkeit an den Rändern erreicht. Es ist auch bereits ein Verfahren zur Isolierung von Spulen aus Flachleitern für elektrische Maschinen bekanntgeworden, deren zwischen den Windungen angeordnete Zwischenisolationen um so viel breiter als die -Breite der Leiter bemessen sind, daß sie, nach den Seitenflächen der Spulen umgelegt, mehr als eine Windung übergreifen. Die Spulen und deren beiderseitig mit Klebstoff versehene, an den Seitenflächen einander dachziegelartig überragenden Isolationszwischenlagen werden unter gleichzeitiger Erwärmung einer von allen Seiteneinwirkenden Pressung unterworfen. Schließlich ist es auch schon bei soggenannten Wicklungsstäben für elektrische Maschinen bekanntgeworden, die Isolierung an den Rändern überstehen zu lassen und um die Leiter, herumzuschlagen. Diese Stäbe haben Beinen großen Leiterquerschnitt und lassen sich also mit aus einer Folie bestehenden Leitern gar nicht vergleichen. Es tritt bei diesen bekannten Verfahren und Anordnungen die der Erfindung zugrunde liegende Aufgabe, beim Wickeln von Spulen mit aus Folien bestehenden Leitern dafür zu sorgen, daß die Folie neben großer dielektrischer Festigkeit an den Rändern eine derart gute mechanische Festigkeit erhält, daß ein Zerreißen der Folie beim Wickeln vermieden wird, überhaupt nicht auf.Electrical conductors made from a film sprayed onto insulating tape exist are already known; however, they are subject to mechanical bending stresses not grown when winding bobbins. By flipping the over the slide protruding edges of the insulating tape around the film, this disadvantage is eliminated and at the same time also the further advantage of greater dielectric strength reached at the edges. It is also already a method of isolating coils became known from flat conductors for electrical machines, whose between the windings arranged intermediate insulation is so much wider than the width of the conductor are that they, folded over to the side surfaces of the coils, more than one turn overlap. The coils and their adhesive on both sides on the side surfaces Intermediate insulation layers that tower over each other like roof tiles are under simultaneous Heating subjected to pressure acting on all sides. Finally is it has already become known for so-called winding bars for electrical machines, Leaving the insulation sticking out at the edges and wrapping around the ladder. These rods have legs with a large conductor cross-section and can therefore be combined with one Do not compare foil with existing ladders. It occurs with these known procedures and arrangements, the object underlying the invention, when winding bobbins Using foil conductors to ensure that the foil is next to large dielectric Strength at the edges so good mechanical strength that a Tearing of the foil during winding is avoided, not at all.

Vorbeschrieben ist es auch des weiteren, bandförmige Leiter zur Isolation in der Längsrichtung auf ein Isolierband, welches sie an beiden Seiten überragt,-zu legen und die überstehenden Ränder des Isoliermaterials um die Seitenkanten des Bandes herumzuschlagen. Diese Maßnahme dient bei den bekannten Drähten einzig dem Zwecke, eine einfache Isolation zu schaffen. Die der Erfindung zugrunde liegende Aufgabe, daß auch die Festigkeit der bandförmigen Leiter erhöht werden soll, spielt dabei 'kleine Rolle. . Ein gemäß der Erfindung ausgebildeter -ele'ktrischei Leiter ist vorzugsweise für Wicklungen von Induktionsapparaten geeignet, bei denen ies darauf ankommt, möglichst viel Windungen bei geringstem Raumbedarf anzubringen, wie dies beispielsweise bei Spannungswandlern für höhere Spannungen erforderlich ist. Es ist -in vielen Fällen vorteilhaft, in an sich bekannter Weise #die Stärke des Isolierbandes durch Einlaufen von weiteren Isolierbändern- nach Belieben, etwa an den Eingangswindungen, zu verstärken. Das Isolierband kann beispielsweise aus Papier bestehen.It is also described above, tape-shaped conductors for insulation in the longitudinal direction on an insulating tape, which protrudes beyond them on both sides, -zu and place the protruding edges of the insulating material around the side edges of the Band around. This measure is only used for the known wires Purposes to create simple isolation. The underlying of the invention Task that the strength of the ribbon-shaped conductor should be increased, plays thereby 'small role. . A -ele'ktrischei trained according to the invention Conductor is preferably suitable for windings of induction devices in which It is important to make as many turns as possible with the least amount of space required, as required, for example, with voltage converters for higher voltages is. In many cases it is advantageous, in a manner known per se, # the strength of the insulating tape by running in further insulating tapes - at will, for example on the input windings to reinforce. The insulating tape can be made of, for example Made of paper.
