Description

Bei Hochspannungssicherungen größerer Leistung nach Patent 494 132, bei denen der Schmelzdraht durch eine Reihe Isolierplatten hindurchgeführt wird, ist es schwierig, festzustellen, ob die betreffende Sicherung noch intakt ist oder durch irgendeine äußere Ursache zum Abschmelzen gebracht wurde. Es ist daher notwendig, eine Anordnung zu treffen, die äußerlich erkennen läßt, in welchem Zustand sich die Sicherung befindet. Da der Sicherungsschmelzleiter die Isolationsplatten in Windungen um die Achse durchsetzt, also eine Art Spule darstellt, kann man eine Anzeigevorrichtung in der Weise leicht anbauen, daß innerhalb der Isolierplatten eine Schraubenlinie aus Leitungsmaterial angeordnet ist, deren Enden an eine Meßvorrichtung angeschlossen werden. Man wird an dem Anzeigeapparat einen Ausschlag erhalten und so ohneIn the case of high-voltage fuses of greater power according to Patent 494 132, in which the Fusible wire is passed through a series of insulating plates, it is difficult to determine whether the fuse in question is still intact or due to some external cause was brought to melt. It is therefore necessary to make an arrangement which shows the state of the fuse from the outside. Since the Fuse fuse penetrates the insulation plates in turns around the axis, that is represents a kind of coil, a display device can easily be attached in such a way that that a helix made of line material is arranged within the insulating plates, the ends of which are connected to a measuring device. One becomes at the display apparatus get a rash and so without

ao Schwierigkeiten erkennen können, ob die Sicherung intakt ist.ao Difficulty being able to tell whether the fuse is intact.

Eine der möglichen Ausführungsformen ist in der Zeichnung dargestellt. Die Isolierplatten α sind zwischen den Kontaktmessern b und c angeordnet und werden durch den Schmelzleiter d in Windungen durchsetzt, e ist die innerhalb der Platten α angebrachte Spule, deren Enden auf eine Meßeinrichtung / arbeiten. Der Schmelzleiter d erzeugt in der Spule e einen Strom, so daß man an dem Meßinstrument f erkennen kann, ob die Sicherung noch intakt ist.One of the possible embodiments is shown in the drawing. The insulating plates α are arranged between the contact blades b and c and are penetrated in turns by the fusible conductor d , e is the coil attached within the plates α , the ends of which work on a measuring device /. The fusible conductor d generates a current in the coil e , so that one can see from the measuring instrument f whether the fuse is still intact.
