  Sicherung fur elektrische Stromkreise. 



   Die bekannten Schmelzsicherungen für elektrische Stromkreise haben die Eigenschaft, dass sie bei Überschreiten einer gewissen Stromstärke ansprechen und den   durchfliessenden   Strom abschalten. 



  Um die Sicherung wieder brauchbar zu machen, muss der Schmelzdraht ersetzt werden. Um den Nachteil des Ersetzens des Sehmelzdrahtes zu vermeiden, ist vorgeschlagen worden, den Schmelzdraht durch eine   leitende Flüssigkeit   zu ersetzen, welche selbständig in das Sicherungsrohr hineinfliessen kann. Ein An- 
 EMI1.1 
 bekannten Anordnungen nicht möglich. 



   Um diesen Mangel zu beseitigen, wird erfindungsgemäss in die leitende Flüssigkeit (z. B. Quecksilber) einer Sicherung Pressluft hineingeblasen, so dass die Flüssigkeitssäule unterbrochen und aus dem Sicherungsrohr herausgestossen wird. 



   Die Einrichtung gemäss der Erfindung besitzt dem Bekannten gegenüber Vorteile, indem Pressluft leicht erhältlich ist und die leitende Flüssigkeit restlos aus dem   Sieherungsrohr   ausgestossen wird, so dass keine leitenden Reste, welche den Strom führen könnten, übrigbleiben. Wenn die Flüssigkeit aus dem Sicherungsrohr ausgestossen ist, wird die Pressluft durch das letztere durchströmen und das Auslöschen des Lichtbogens begünstigen. 



   Durch diese Anordnung ist es also möglich, dass die Sicherung für einen beliebigen Dauerstrom bemessen werden kann, aber doch einen beliebigen kleineren Strom zu einem beliebigen Moment abschalten kann.

  Fuse for electrical circuits.



   The known fuses for electrical circuits have the property that they respond when a certain current strength is exceeded and switch off the current flowing through.



  To make the fuse usable again, the fuse wire must be replaced. In order to avoid the disadvantage of replacing the melting wire, it has been proposed to replace the melting wire with a conductive liquid which can flow independently into the safety tube. An on
 EMI1.1
 known arrangements not possible.



   In order to eliminate this deficiency, according to the invention, compressed air is blown into the conductive liquid (for example mercury) of a fuse, so that the liquid column is interrupted and pushed out of the fuse tube.



   The device according to the invention has advantages over the known in that compressed air is easily available and the conductive liquid is completely expelled from the sieve tube so that no conductive residues which could conduct the current remain. When the liquid is expelled from the safety tube, the compressed air will flow through the latter and favor the extinguishing of the arc.



   With this arrangement it is possible that the fuse can be rated for any continuous current, but can switch off any smaller current at any moment.
