Description
Die Erfindung betrifft einen elektrischen Wickelkondensator, welcher aus Dielektrikumsfolien aus Polypropylen und Metallfolien aus einem der Stoffe Aluminium, Nickel, Zink, Zinn oder Blei oder aus Legierungen dieser Stoffe gewickelt ist und bei welchem die Polypropylenfolien geschrumpft sind, wodurch in den Wickel eingesetzte metallische Anschlußteile, die im wesentlichen aus Kupfer bestehen, mechanisch festgehalten sind.The invention relates to an electrical wound capacitor made of dielectric films made of polypropylene and metal foils made of one of the materials aluminum, nickel, zinc, tin or lead or of alloys of these Fabrics is wrapped and in which the polypropylene films have shrunk, causing in the wrap inserted metallic connecting parts, which consist essentially of copper, held mechanically are.
Aus der US-PS 33 91313 ist ein elektrischer Wickelkondensator bekannt, dessen Dielektrikumsfolien z. B. aus Polypropylen bestehen, und der Metallfolien aus Aluminium oder einer Blei-Zinn-Legierung besitzt Die Anschlußteile dieses Kondensators bestehen aus Kupfer oder Stahl und weisen an einem Ende zur Verankerung im Kondensator Widerhaken auf. Das Ende des Widerhakens kann bei Anschlußteilen aus Kupfer verzinnt sein.From US-PS 33 91313 is an electrical Winding capacitor known, the dielectric foils z. B. consist of polypropylene, and the metal foils The connection parts of this capacitor are made of aluminum or a lead-tin alloy made of copper or steel and have barbs at one end for anchoring in the capacitor. That The end of the barb can be tinned in connection parts made of copper.
Beim Betrieb des bekannten Kondensators, der als Dielektrikumsmaterial Polypropylen und als Material für die Anschlußteile Kupfer, das mit dem Dielektrikumsmaterial in Berührung ist, aufweist, treten im Dauerbetrieb Ausfälle durch Spannungsdurchschläge auf, deren Ursache bisher nicht aufgeklärt werden konnte.When operating the known capacitor, which is used as a dielectric material and polypropylene as a material for the connection parts copper, which is in contact with the dielectric material, occur in Continuous operation, failures due to voltage breakdowns, the cause of which has not yet been clarified could.
Aufgabe der Erfindung ist es, einen Kondensator der eingangs angegebenen Art anzugeben, bei welchem auch bei längerem Dauerbetrieb keine Spannungsdurchschläge auftreten, und der sich somit durch eineThe object of the invention is to provide a capacitor of the type specified at the outset, in which no voltage breakdowns occur even with long-term continuous operation, and thus through a
längere Lebensdauer auszeichnetlonger service life
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zumindest jeweils der gesamte mit dem Polypropylen in Berührung stehende Abschnitt der Anschlußteile mit Nickel, Zink, Zinn oder Blei oder Legierungen dieser Stoffe überzogen istThis object is achieved according to the invention in that at least in each case the entire with the polypropylene section of the connecting parts in contact with nickel, zinc, tin or lead or alloys of these Fabric is coated
Die Vorteile des Gegenstandes der Erfindung bestehen darin, daß ein derartiger Kondensator auch bei längerem Dauerbetrieb keine Spannungsdurchschläge aufweist, und der sich somit durch eine längere Lebensdauer als die bekannten Kondensatoren auszeichnet The advantages of the object of the invention are that such a capacitor also with does not show any voltage breakdowns during longer continuous operation, and thus through a longer Lifetime than the well-known capacitors
Dies ist darauf zurückzuführen, daß die bisher nicht bekannte Ursache für die Spannungsdurchschläge darinThis is due to the fact that the previously unknown cause of the voltage breakdowns therein
is besteht, daß Kupfer wie auch Silber eine Zersetzung des Polypropylens hervorrufen, wenn es mit diesen Metallen direkt in Berührung steht, und zwar unabhängig davon, ob eine elektrische Spannung anliegt oder nicht Auch Legierungen, die Kupfer oder Silber enthalten, bewirken eine Zersetzung des Polypropylens.It is a fact that copper, like silver, is a decomposition of the Polypropylene when it is in direct contact with these metals, independently whether an electrical voltage is applied or not. Also alloys, the copper or silver contain, cause the polypropylene to decompose.
daß bei 85° C zur Zerstörung einer 20μπι dickenthat at 85 ° C to destroy a 20μπι thick
dadurch aus, daß die Anschlußteile aus dem besonders duktilen Kupfer hergestellt werden können, ohne daß
die in Bezug auf Polypropylenfolien negativen Eigenschaften auftreten.
Ein Überzug aus Nickel zeichnet sich durch eine gute Schweißbarkeit und Korrosionsbeständigkeit bei
Raumtemperatur aus, was für eine Lagerung der Kondensatoren vor einem Einschweißen in eine
Schaltung durch den Anwender vorteilhaft ist, da eine spezielle Behandlung zur Entfernung einer Korrosionsschicht
auf dem Nickel vor dem Einschweißen entfälltcharacterized in that the connection parts can be made from the particularly ductile copper without the negative properties in relation to polypropylene foils occurring.
A coating made of nickel is characterized by good weldability and corrosion resistance at room temperature, which is advantageous for the user to store the capacitors before welding them into a circuit, since there is no special treatment to remove a corrosion layer on the nickel before welding
Eine Weiterbildung der Erfindung zeichnet sich dadurch aus, daß die genannten Abschnitte der Anschlußteile mit einer Zinn-Blei-Legierung überzogen sind, die 60% Zinn und 40% Blei enthältA development of the invention is characterized in that the aforementioned sections of the Connection parts are coated with a tin-lead alloy, which contains 60% tin and 40% lead
Diese Legierung, die z. B. in der Norm DIN 1707 unter der Bezeichnung LSn 60 Pb angeführt ist, zeichnet sich durch gute Lötfähigkeit aus.This alloy, which z. B. is listed in the standard DIN 1707 under the designation LSn 60 Pb, draws are distinguished by their good solderability.
Ein weiterer Vorteil des Anmeldungsgegenstandes besteht darin, daß die Anschlußteile, die lediglich durch die Schrumpfkräfte der Polypropylenfolien mechanisch festgehalten werden, während der gesamten Betriebsdauer des Kondensators fest verankert werden, ohne daß eine spezielle Ausbildung, wie z. B. Widerhaken, erforderlich wäre.Another advantage of the subject of the application is that the connecting parts, which only through the shrinkage forces of the polypropylene films are mechanically retained during the entire service life of the capacitor are firmly anchored without a special training, such. B. barbs, would be required.
so Die aufgeführten Vorteile des Anmeldungsgegenstandes gewährleisten somit eine lange Betriebsdauer der Kondensatoren, da einerseits Spannungsdurchschläge nicht mehr auftreten und andererseits die mechanische Halterung der Anschlußteile sichergestellt istThe listed advantages of the subject of the application thus ensure a long service life the capacitors, because on the one hand voltage breakdowns no longer occur and on the other hand the mechanical Holding the connecting parts is ensured
