Schmelzsicherung.
Sicherungen müssen so hergestellt sein, dass sie auch bei Kurzschluss den auftretenden Lichtbogen zum Erlöschen bringen, ohne dass die Contacte oder die Leitungen zerstört worden. Um für Mittelspannungen und Hochspannungen nicht zu grosse Abmessungen der Sicherungen zu erhalten, hat man mechanisch, magnetisch oder dynamisch wirkende Anordnungen getroffen.
Bei der Sicherung, die den Gegenstand vorliegender Erfindung bildet, ist besonders darauf Rücksicht genommen worden, dass, unbeschadet der Wirksamkeit der Sicherung, möglichst wenig Metall verbrenne, da die starke Entwickelung von Metalldämpfen haupt- sächlich zur Vergrösserung des Lichtbogens beiträgt. Bei einem Schmelzstreifen (Fig. 1) mit einer Einschnürung a in der Mitte entsteht an der Schmelzstelle verhältnismässig starkos
EMI1.1
Die Bügel b können entweder von gleichem Material, aber mit verstärktem Quer- schnitt, wie die Schmoizstreifen c sein oder es können beispielsweise die Schmelzstreifen c aus Silberdraht, die Verbindungsbügel dagegen aus Kupferblech bestehen. Stets wird bei der beschriebenen Anordnung die gleiche Wirkung auftreten, und es werden verhältnismässig geringe Mengen Metall verbrannt.

werden.
Versuche haben ergeben, dass bei Kurzschlüssen mit Maschinen von grosser Leistung die Sicherungen sicher wirken ; der Lichtbogen ist auch bei Kurzschlüssen gering und erlischselbstbeiallmählichgesteigerterStromstärkesofort.
Anstatt zwei Sehmelzstreifen zu einer Sicherung zu verbinden, können deren mehrere verbunden werden, z. H. vier zu einem Doppel-U.

Fuse.
Fuses must be manufactured in such a way that they extinguish the arcing that occurs even in the event of a short circuit, without the contacts or the lines being destroyed. Mechanically, magnetically or dynamically acting arrangements have been made so that the dimensions of the fuses are not too large for medium voltages and high voltages.
In the fuse, which is the subject of the present invention, particular care has been taken to ensure that, irrespective of the effectiveness of the fuse, as little metal as possible burns, since the strong development of metal vapors mainly contributes to the enlargement of the arc. In the case of a melting strip (Fig. 1) with a constriction a in the middle, relatively strongos occurs at the melting point
EMI1.1
The brackets b can either be made of the same material, but with a reinforced cross-section, like the Schmoiz strips c or, for example, the melt strips c can be made of silver wire, whereas the connecting brackets are made of sheet copper. The same effect will always occur with the arrangement described, and relatively small amounts of metal are burned.
EMI1.2
will.
Tests have shown that in the event of short circuits with high-performance machines, the fuses work safely; the arc is small even in the event of short circuits and extinguishes immediately, even with gradually increased current.
Instead of connecting two strips of clay to a fuse, several can be connected, e.g. H. four to a double U.
