Description
Verfahren zur Bemessung des elektrischen Widerstandes von Schmelzleitern Bei der Fertigung von Schmelzleitern, die durch Aufbringen, z. B. durch Aufspritzen, Aufstreichen, Galvanisieren o. dgl., eines Metallbelages auf einen Träger aus Isoliermaterial, wie z. B. aus keramischen Baustoffen, hergestellt sind, bestehen Schwierigkeiten, die Schmelzleiter für einen bestimmten vorgeschriebenen elektrischen Widerstand zu bemessen. Derartige Schmelzleiter werden, insbesondere für Schmelzeinsätze, von elektrischen Sicherungen benötigt, bei denen es auf eine genaue Bemessung des elektrischen Widerstandes ankommt, damit die erforderliche Genauigkeit der Abschmelzwerte erreicht wird.Procedure for measuring the electrical resistance of fusible conductors In the manufacture of fusible conductors, which by applying, for. B. by spraying, Painting, electroplating or the like, a metal coating on a carrier made of insulating material, such as B. made of ceramic building materials, there are difficulties the fusible link for a certain prescribed electrical resistance to measure. Such fusible conductors are, in particular for fuse inserts, of electrical fuses are required, where there is a precise dimensioning of the electrical Resistance arrives so that the required accuracy of the meltdown values is achieved will.
Gemäß der Erfindung wird der als Schmelzleiter dienende Metallbelag von vornherein stärker als nötig, d. h. mit einem geringeren Widerstand aufgebracht und nachträglich unter Kontrolle von ins, besondere selbsttätig wirkenden Meßeinrichtungen durch Schleifen, Polieren, Schaben, Ätzen o. dgl. auf den gewünschten Wert gebracht. Durch einfache Feilstriche ist es beispielsweise möglich, den jeweils erforderlichen elektrischen Widerstand zu bemessen.According to the invention, the metal coating serving as a fusible link is used stronger than necessary from the start, d. H. applied with a lower resistance and subsequently under the control of, in particular, automatic measuring devices brought to the desired value by grinding, polishing, scraping, etching or the like. By means of simple lines of the file, it is possible, for example, to determine the required to measure electrical resistance.
