Description

Schmelzsicherung für elektrische Stromkreise Gegenstand der Erfindung ist eine Schmelzsicherung für elektrische Stromkreise, deren Auslösestrom auf einem besonders zuverlässig einzuhaltenden Wert gehalten werden kann.Fuse for electrical circuits is the subject of the invention is a fuse for electrical circuits whose tripping current is on a can be kept particularly reliable value.

Nach der Erfindung besteht die Schmelzsicherung aus einem als Einkristall ausgebildeten Schmelzkörper. Eine derartige Schmelzsicherung ist durch die an sich bekannten Eigenschaften von Einkristallen in elektrischer Hinsicht besonders brauchbar..According to the invention, the fuse consists of a single crystal trained melting body. Such a fuse is by itself known properties of single crystals are particularly useful in electrical terms.

Einkristalle weisen eine vollkommen gleichmäßige Struktur auf, ihr Material ist vollkommen homogen. Einkristalle sind ferner besonders gut zu bearbeiten und lassen sich daher ohne großen Arbeitsaufwand in die für eine Sicherung gewünschten Dimensionen unter Einhaltung genauester Herstellungsmaße bringen. Durch die Homogenität des Materials der Sicherung ist deren Auslösestromstärke aus den Dimensionen der Sicherung genau bestimmbar.Single crystals have a perfectly uniform structure, you Material is completely homogeneous. Single crystals are also particularly easy to work with and can therefore be converted to the ones required for a backup without a great deal of work Bring dimensions in compliance with the most precise manufacturing dimensions. Because of the homogeneity of the fuse material is its tripping current from the dimensions of the Securing precisely determinable.

Statt einen einzigen Schmelzkörper aus Einkristall zu verwenden, ist es unter Umständen vorteilhaft, mehrere parallel geschaltete Schmelzleiter zu verwenden, von denen nur einer als Einkristall ausgeführt ist. Zweckmäßig wird man dann die Schwächung des Stromes durch einen Schmelzstreifen aus einem anderen Material hervorrufen, worauf die endgültige Abschaltung durch den als Einkristall ausgebildeten Schmelzkörper mit genau festgelegter Auslösestromstärke erfolgt.Instead of using a single fusible body made of single crystal, is it may be advantageous to use several fusible conductors connected in parallel, only one of which is a single crystal. Appropriately, one then becomes the Cause a weakening of the current by a melt strip made of another material, whereupon the final shutdown by the single-crystal melting body takes place with a precisely defined tripping current.

Als Material der Schmelzsicherung nach der Erfindung kann man alle Metalle wählen, aus denen sich Einkristalle leicht herstellen lassen; es sind dies beispielsweise Kupfer, Silber, Zinn, Blei usw.The material of the fuse according to the invention can be any Choose metals from which single crystals can be easily made; it is this for example copper, silver, tin, lead, etc.
