Description
DEUTSCHESGERMAN
Die vorliegende Erfindung stellt eine weitere vorteilhafte Ausbildung der im Hauptpatent 1 071 208 beschriebenen elektrodynamischen Schnellausschalt-Einrichtung zur Begrenzung und Abschaltung von Überströmen und Kurzschlußströmen, insbesondere für Gleichstrom-Hochstromanlagen dar, wobei in dem zu schützenden Kreis ein mit mindestens zwei Einschnürungen versehener Stromleiter, der im Überstrom- und Kurzschlußfall durch elektrodynamische Kräfte abgeschert wird, und eine ihn beeinflussende, vom Hauptstrom durchflossen Spule angeordnet sind. Hierbei übt das magnetische Feld der Drossel auf den Stromleiter eine Kraft aus, welche quadratisch mit dem Strom ansteigt. Falls dieser rasch wächst, beispielsweise bei einem Kurzschluß, nimmt die Festigkeit der hochbelasteten Einschnürstellen infolge der schnellen Temperaturerhöhung schlagartig ab, und es tritt eine Abscherung des Schaltelementes vor dem Erreichen der Schmelztemperatur ein, wobei der frei, gewordene Leiterteil mit erheblicher Beschleunigung weggeschleudert wird.The present invention represents a further advantageous embodiment of that described in the main patent 1,071,208 electrodynamic quick disconnect device for limiting and disconnecting overcurrents and short-circuit currents, in particular for direct current high-current systems, in which to protective circuit a conductor provided with at least two constrictions, which in the overcurrent and short-circuit case is sheared off by electrodynamic forces, and an influencing the main current flowing through the coil are arranged. Here, the magnetic field of the choke acts on the Conductors generate a force that increases quadratically with the current. If this is growing rapidly, for example in the event of a short circuit, the strength of the highly stressed constriction points decreases as a result of the rapid The temperature increase abruptly and the switching element shears off before it is reached the melting temperature, whereby the conductor part that has become free is thrown away with considerable acceleration will.
Es sind nun noch weitere Verbesserungen im Hinblick auf größere Ausschaltleitungen, kürzere Schaltzeiten und eine gedrängte Bauweise möglich, wenn erfindungsgemäß der Abscherleiter im Innern der Dros- as seispule angeordnet wird. Bei einer 'bekannten Einrichtung" zur Überwachung der Kurzschlüsse an Gleichrichtern sind zwar schon Schaltstrecken in Achsrichtung einer Drosselspule angeordnet worden, jedoch außerhalb dieser Spule. Dort besteht aber bereits eine Schwächung des magnetischen Feldes, so daß zusätzliche Blasspulen erforderlich werden. Ferner sind bei der bekannten Einrichtung keine Abscherleiter mit Einschnürungen vorhanden, sondern Schnellschalter, die teuer sind und eine regelmäßige Wartung der Kontakte erfordern.There are now further improvements with regard to larger switch-off lines and shorter switching times and a compact design is possible if, according to the invention, the shear conductor is inside the Dros- as sepool is arranged. In a 'known device' for monitoring the short circuits Rectifiers have already been arranged switching paths in the axial direction of a choke coil, but outside of this coil. But there is already a weakening of the magnetic field, so that additional blow coils are required. Furthermore, there are no shear conductors in the known device with constrictions present, but quick-action switches that are expensive and require regular maintenance of contacts require.
Gemäß weiteren Merkmalen der Erfindung ist es zweckmäßig, die Schaltstrecke mit Lichtbogenhörnern und Lichtbogenkammern zu versehen und diese ebenfalls im Innern der Drosselspule anzuordnen. Schließ-Hch ist durch geeignete Lichtbogenführung dafür zu sorgen, daß ein Auftreten des Schaltfeuers außerhalb der Drosselspule verhindert wird und die beim Schaltvorgang entstehenden ionisierten Gase mit Hilfe von Einbauteilen abgelenkt werden.According to further features of the invention, it is expedient to use arcing horns for the switching path and to provide arc chambers and to arrange these also inside the reactor. Closing Hch it is to be ensured by means of suitable arc guidance that the switching fire occurs outside the choke coil is prevented and the ionized gases generated during the switching process with the help of Built-in parts are distracted.
Die Zeichnung gibt ein Ausführungsbeispiel des Erfindungsgegenstandes vereinfacht wieder.The drawing gives an embodiment of the subject matter of the invention simplified again.
In Fig. 1 ist mit 1 die Drosselspule und mit 2 die Schaltstrecke bezeichnet, welche aus einem Abscherleiter besteht. Die Lichtbogenhörner haben die Bezugsziffer 3, die Einbauteile aus Isoliermaterial oder Metall die Ziffer 4 und die Seitenwände des Funkenkamins das Bezugszeichen 6. Die Isolation 5 der Drosselspule dient zum Schutz gegen den Lichtbogen.In Fig. 1, 1 denotes the choke coil and 2 denotes the switching path, which consists of a shear conductor consists. The arcing horns have the reference number 3, the built-in parts made of insulating material or metal the number 4 and the side walls of the spark chimney the reference number 6. The insulation 5 of the choke coil serves to protect against the arc.
