Description

Elektrische Dauersicherung mit Quecksilberfüllung. Die Erfindung betrifft eine elektrische Dauersicherung. Sicherungen mit einem Sicherungsfaden aus Quecksilber oder einem Ouecksilberamälgam sind bereits bekannt. Der größte Nachteil dieser bekannten Einrichtungen besteht darin, daß der einmal entstandene Lichtbogen bis zur endgültigen Beseitigung der Störung weiterbrennt. Hierdurch wird ein luftdichter Abschluß der Sicherung wegen der Explosionsgefahr erschwert.Permanent electrical fuse with mercury filling. The invention relates to a permanent electrical fuse. Fuses with a mercury fuse thread or a mercury amälgam are already known. The main disadvantage of this known Facilities consists in the fact that the once created arc to the final Elimination of the fault continues to burn. This creates an airtight seal for the Securing difficult because of the risk of explosion.

Gegenstand der Erfindung ist eine Sicherung, bei der das Weiterbrennen des Lichtbogens ausgeschlossen ist. Sie ist auf folgendem Prinzip aufgebaut: Als Sicherungsfaden wird Quecksilber mit einer Beimengung eines leichtverdampfbaren Nichtleiters, dessen Siedepunkt unter dem des Quecksilbers liegt, verwendet. Wird nun der Quecksilberfaden überlastet, so erhitzt sich das Quecksilber sowohl als auch der Nichtleiter. Dieser verdampft und bildet in der leichtgewölbten-Schaltröhre eine Dampfblase, welche den Quecksilberfaden auseinanderreißt. Natürlich entsteht im Augenblick des Auseinanderreißens ein Lichtbogen, der jedoch sofort auslöscht, da die sich weiter entwickelnden Nichtleiterdämpfe die beiden Enden immer weiter auseinanderdrängen. Als Nichtleiter käme etwa ein Öl oder gewöhnliches Wasser in Frage.The invention relates to a fuse in which burning continues the arc is excluded. It is based on the following principle: As Fuse thread is made of mercury with an admixture of an easily evaporable Insulator with a boiling point below that of mercury is used. Will if the mercury thread is overloaded, the mercury heats up as well as also the non-conductor. This evaporates and forms in the slightly curved interrupter a vapor bubble tearing apart the mercury thread. Naturally arises at the moment of tearing apart an arc, which however is extinguished immediately, as the evolving dielectric vapors continue to widen the two ends push apart. An oil or ordinary water would come in as a non-conductor Question.

Die Schaltröhre, in der sich der Faden befindet, ist nach der Stromstärke bemessen; in der Praxis sind ihrem Querschnitt keine Grenzen gezogen.The interrupter in which the thread is located is according to the strength of the current sized; in practice, there are no limits to its cross-section.
