Description

DEUTSCHESGERMAN

Es ist bekannt, zum schnellen Unterbrechen elektrischer Stromkreise die in chemischen Treib- oder Sprengladungen gespeicherte Energie auszunutzen. Ein Vorschlag sieht auch vor, Schmelzsicherungen mit einer Sprengladung zu versehen. Im Bereich begrenzter Überströme wirkt die Sicherung in üblicher Weise durch Abschmelzen des Schmelzleiters. Bei hohen Kurzschlußströmen soll dagegen auf mechanischem oder elektrischem Wege eine Zündung der Sprengladung erfolgen, wodurch der Schmelzleiter in kürzester Zeit zerstört und damit der Stromkreis unterbrochen wird.It is known to quickly interrupt electrical circuits in chemical propellants or Exploiting explosive charges stored energy. One proposal also provides for fuses to be provided with an explosive charge. In the area of limited overcurrents, the fuse works as usual Way by melting the fuse element. In the case of high short-circuit currents, on the other hand, mechanical or by electrical means an ignition of the explosive charge takes place, whereby the fusible conductor destroyed in a very short time and thus the circuit is interrupted.

Die Erfindung schafft eine besonders rasch wirkende Zündeinrichtung für Schmelzsicherungen mit Sprengladung und Hilfsschmelzleiter. Die Erfindung besteht darin, daß der Hilfsschmelzleiter in Reihe mit einem elektrischen Ventil, insbesondere einem Halbleitergleichrichter, parallel zu dem Schmelzleiter geschaltet ist.The invention creates a particularly fast-acting ignition device for fuses with an explosive charge and auxiliary fusible link. The invention is that the auxiliary fusible conductor in series with a electric valve, in particular a semiconductor rectifier, connected in parallel to the fusible conductor is.

Zur Erläuterung der Erfindung ist in der Zeichnung schematisch ein Ausführungsbeispiel einer derartigen Sicherung dargestellt. Der Schmelzleiter 1 trägt eine Sprengladung 2. Diese Ladung steht in Berührung mit einem Hilfsleiter 3, der, in Reihe mit einem oder mehreren Trockengleichrichterelementen 4, parallel zu dem Schmelzleiter 1 geschaltet ist. Schmelzleiter und Gleichrichter 4 sind so bemessen, daß der im Normalbetrieb an dem Schmelzleiter 1 auftretende Spannungsabfall unterhalb der Schwellspannung des Gleichrichters 4 liegt, so daß im normalen Betrieb der Hilfsleiter 3 stromlos bleibt. Im Kurzschlußfall erhöht sich jedoch der Spannungsabfall am Schmelzleiter 1, so daß die Schwellspannung des Gleichrichters 4 überschritten wird und der dann über den Hilfsschmelzleiter 3 fließende Strom diesen in kürzester Zeit zum Glühen bzw. Schmelzen bringt, was die Explosion der Sprengladung 2 und damit auch die Zerstörung des Schmelzleiters 1 zur Folge hat.To explain the invention, an embodiment of such a fuse is shown schematically in the drawing. The fusible conductor 1 carries an explosive charge 2. This charge is in contact with an auxiliary conductor 3 which, in series with one or more dry rectifier elements 4, is connected in parallel with the fusible conductor 1 . Fusible conductor and rectifier 4 are dimensioned so that the voltage drop occurring on fusible conductor 1 during normal operation is below the threshold voltage of rectifier 4 , so that auxiliary conductor 3 remains de-energized during normal operation. In the event of a short circuit, however, the voltage drop at the fuse element 1 increases, so that the threshold voltage of the rectifier 4 is exceeded and the current then flowing through the auxiliary fuse element 3 causes it to glow or melt in a very short time, which causes the explosion of the explosive charge 2 and thus also the Destruction of the fuse element 1 has the consequence.

An Stelle des in der Zeichnung angedeuteten Schmelzdrahtes 1 kann der Schmelzleiter auch die Schmelzsicherung mit Sprengladung
und Hilfsschmelzleiter
Instead of the fusible wire 1 indicated in the drawing, the fusible conductor can also be the fuse with an explosive charge
and auxiliary fusible link

Gestalt eines Rohres haben, in dessen Innerem die Sprengladung angeordnet ist.Have the shape of a tube, inside which the explosive charge is arranged.

Falls eine Anordnung nach der Erfindung zur Sicherung sowohl gegen Überstrom als auch Rückstrom dienen soll, können zwei Halbleiterventile in Gegenparallelschaltung verwendet werden. Dabei kann die Anordnung zweckmäßig so getroffen werden, daß das Ventil für Rückstrom geringere Schwellspannung besitzt als das andere Ventil.If an arrangement according to the invention for securing against both overcurrent and reverse current is to serve, two semiconductor valves can be used in opposite parallel connection. Here can the arrangement can expediently be made so that the valve for reverse current has a lower threshold voltage than the other valve.
