Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Spulen in Scheibenform für Wechselstromapparate, insbesondere für Drosselspulen und Transformatoren, sind bekanntlich an den Eintrittsstellen am meisten gefährdet, da beim Einschalten momentan die volle Netzspannung zwischen den benachbarten Windungen auftritt und ebenso Wanderwellen mit dem ganzen Betrage ihrer Spannung die Isolation an der Eintrittsstelle beanspruchen.Disc-shaped coils for alternating current apparatus, in particular for choke coils and Transformers are known to be most at risk at the points of entry, because at Switching on momentarily the full mains voltage occurs between the neighboring windings and also traveling waves with the full amount of their tension claim the insulation at the point of entry.

ίο Bei der bisherigen Ausführungsform der Scheibenspulen ist es nun nicht ohne weiteres möglich, die Isolation zwischen benachbarten Windungen an der Eintrittsstelle zu messen.ίο With the previous embodiment of the disc coils, it is not straightforward possible to measure the insulation between adjacent turns at the point of entry.

Gemäß der Erfindung wird die Isolationsprüfung an der Eintrittsstelle dadurch ermöglicht, daß die Scheibenspule aus mindestens zwei' konzentrisch gewickelten Leitern hergestellt wird, die erst nach erfolgter Isolationsprüfung derart hintereinander geschaltet wer- den, daß der richtige Wicklungssinn erhalten wird. Es wird also das Ende der ersten Lage mit dem Anfang der zweiten Lage verbunden. According to the invention, the insulation test at the entry point is made possible by that the disc coil made of at least two 'concentrically wound conductors which are only switched one after the other after the insulation test has been carried out. that the correct winding sense is obtained. So it will be the end of the first Layer connected to the beginning of the second layer.

In der Figur, die schematisch die neue Anordnung mit zwei konzentrischen Leitern zeigt, ist die erste Lage α ausgezogen, die zweite Lage b gestrichelt gezeichnet. Das Ende von α ist durch die Verbindung c mit dem Anfang von b verbunden; die Verbindung c wird jedoch erst hergestellt, nachdem an der Eintrittsstelle die Isolation zwischen den Windungen α und b geprüft wurde.In the figure, which schematically shows the new arrangement with two concentric conductors, the first layer α is drawn out, the second layer b is shown in dashed lines. The end of α is connected to the beginning of b by the connection c; however, the connection c is only established after the insulation between the turns α and b has been checked at the point of entry.
