Description
DleErfindungbezieht sich auf elektrische Kondensatoren, bei denen der Elektrodenanschluß durch stirnseitig auf den Kondensatorwickel aufgebrachte Meitallbrücken erfolgt. An die Haftfestigkeit dieser meist durch Aufspritzen aufgebrachten Metallbrücken werden bekanntlich hohe Anforderungen gestellt, da der Kondensatorwickel, z. B. durch die Bearbeitung beim Einbau oder im Betrieb bei elektrischen Durchschlagen, unter UmständenThe invention relates to electrical capacitors, in which the electrode connection is applied to the capacitor winding through the face Meitallbrücken takes place. The adhesive strength of these metal bridges, which are usually applied by spraying are known to have high requirements, since the capacitor winding, for. B. by the Processing during installation or during operation in the event of electrical breakdown, possibly
ίο mechanisch erheblich beansprucht werden kann.ίο can be mechanically stressed considerably.
Die Haftfestigkeit der Metallbrüc'ken an elektrischen Kondensatoren mit stimeeitigem Elektrodenanschluß wird erheblich verbessert, wenn, gemäß der Erfindung die innen im Kondensatorwickel liegende Hülse oder die Anfangs leerwindungen, auf die der Wickel aufgerollt ist, und die außen am Wickel liegenden Leerwindungen eine von den übrigen Windungen, des Wickels verschiedene Höhe haben. Die Metallbrücke erfährt durch dieseThe adhesion of metal bridges to electrical Capacitors with electrode connection at the same time is significantly improved if, according to the invention, the inside of the capacitor winding lying sleeve or the initial empty turns on which the winding is rolled up, and the outside Idle turns lying on the coil are one that is different from the other turns of the coil Have height. The metal bridge experiences through this
ao Ausgestaltung eine bessere Verankerung auf der Stirnfläche und findet einen Halt gegen sidtliches Abgleiten.ao design better anchoring on the Face and finds a hold against sliding sideways.
Zu diesem Zweck sind die innen imKondensatorwickel liegende Hülse oder die Anf angsleerwindungen, auf die der Kondensatorwickel aufgerollt ist, kürzer in ihrer Höhe gegenüber den übrigen Windungen des Wickels, während die außen am Kondensatorwickel liegenden Leerwindungen, länger in ihrer Höhe als die übrigen Windungen, des Wickels sind.For this purpose, they are inside the capacitor winding lying sleeve or the initial empty windings on which the capacitor winding is rolled up, shorter in height than the other turns of the winding, while the outside of the capacitor winding lying idle turns, longer in height than the other turns, of the coil are.
Die Abb. 1 zeigt einen Querschnitt durch einen Teil eines Kondensatorwickels. Mit 1 sind die Windungen des Wickels bezeichnet, die als Belegungen und als Dielektrikum elektrisch beansprucht werden. Von diesen Lagen in der Höhe verschieden sind die zusammengepreßte Hülse 2 oder die inneren Leerwindungen, auf die der Wickel aufgerollt ist, und die außen am Wickel befindlichen Leerwindungen 3, die keine metallischen Belegungen tragen.Fig. 1 shows a cross section through part of a capacitor winding. With 1 they are Turns of the winding referred to, which are electrically stressed as coatings and as a dielectric will. The compressed sleeve 2 differs in height from these layers or the inner idle turns on which the roll is rolled up and those on the outside of the roll Empty turns 3 that do not have any metallic coatings.
Die Abb. 2 zeigt im Querschnitt den gleichen Teil des Wickels wie in Abb. 1, nur ist jetzt die Stirnseite mit 'Anschlußmetall4 versehen, z.B. durch Aufspritzen. Der Maßstab in beiden. Abbildungen ist willkürlich übertrieben und soll nur eine schematische Darstellung geben. Die Stirnseitenfläche braucht nicht ganz vom Metall ausgefüllt zu sein, es lassen sich auch zweckmäßig geformte Brücken aufbringen. Fig. 2 shows in cross section the same part of the coil as in Fig. 1, only now it is Provide the end face with connection metal4, e.g. by spraying on. The benchmark in both. Illustrations is arbitrarily exaggerated and is only intended to provide a schematic representation. The end face does not need to be completely filled with metal; appropriately shaped bridges can also be applied.
Damit die anfangs statt einer Hülse aufgewickelten Leerwindungen ohne Metallbelegungen beim Auf wickeln nicht ausschießen, sind vorteilhaft die Ecken der Kanten am Anfang umgeklappt. Die Abb. 3 zeigt die noch nicht aufgerollte flache Bahn, die zu Leerwindungen aufgewickelt werden soll, mit den umgeklappten Ecken 5 und 6.So that the initially wound up instead of a sleeve Do not exclude empty turns without metal coverings when winding on, are advantageous the corners of the edges folded down at the beginning. Fig. 3 shows the flat one that has not yet been rolled up Web that is to be wound up into empty turns with folded corners 5 and 6.
