Bei der elektromagnetischen Auslösung von Schaltern, insbesondere Installationsselbstschaltern, deren Schaltkontakte in der Einschaltlage mechanisch verriegelt sind, wird angestrebt, daß bei Auftreten eines Kurzschlußstromes die Kontaktöffnung in einem möglichst niedrigliegenden Punkt der ansteigenden Kurve des Kurzschlußstromes fällt, d. h. daß die Abschaltung möglichst frühzeitig vor Erreichen des vollen Kurzschluß Stromes zustande kommt.In the case of electromagnetic tripping of switches, especially installation switches, whose switching contacts are mechanically locked in the on position, the aim is to ensure that when of a short-circuit current, the contact opening in the lowest possible point of the rising Short-circuit current curve falls, d. H. that the shutdown as early as possible Achieving the full short-circuit current comes about.
Zur Lösung dieser Aufgabe sind schon verschiedene Maßnahmen angewendet worden, welche teilweise Erfolg brachten, z. B. wurden früher angewendete Kraftspeicher, die erst auf ein geschlossenes Kniegelenksystem einwirkten, durch abgestützte entklinkbare Gelenksysteme ersetzt. Dadurch ergeben sich kürzere Schaltzeichen vom Moment des Auftretens des Kurzschluß stromes bis zum Beginn der Kontaktöffnung, weil weniger Teile beschleunigt und, von den Teilen kleinere Gesamt- ao wege innerhalb dieser Schaltphase zurückgelegt werden müssen. In allen bekannten Fällen wird die Kontaktbrücke noch durch einen besonderen Mechanismus oder mindestens durch einen Hebel arretiert, auf den erst ein Magnetanker einwirken muß. Infolgedessen setzt sich die Zeit vom Auftreten des Kurzschlußstromes bis zum Beginn der Kontaktöffnung immer noch aus den für den Anker-To solve this problem, various measures have already been used, which brought partial success, z. B. were previously used energy storage, which only on a closed The knee joint system, replaced by supported unlatchable joint systems. Through this shorter circuit symbols result from the moment the short-circuit current occurs until at the beginning of the contact opening, because fewer parts are accelerated and, of the parts, smaller overall ao distances have to be covered within this switching phase. In all known cases, the Contact bridge by a special mechanism or at least by a lever locked, on which a magnet armature must first act. As a result, the time continues from occurrence of the short-circuit current up to the beginning of the contact opening still from the armature
