Description
Die Erfindung bezieht sich auf ein Magnetsystem für Leitungsschutzschalter gemäß Oberbegriff von Anspruch 1 und auf ein Verfahren zur Herstellung eines solchen Magnetsystems.The invention relates to a Magnet system for Miniature circuit breakers according to the generic term of claim 1 and a method for producing such Magnet system.
Leitungsschutzschalter werden in der Elektrotechnik zum Schutz von Schaltkreisen gegen Überlastung, z.B. durch Kurzschlüsse oder dgl., verwendet und dienen zur automatischen Unterbrechung einer Leitung, d.h. sie lösen aus, wenn eine solche Überlastung auftritt.Miniature circuit breakers are in electrical engineering to protect circuits against overload, e.g. through short circuits or the like, used and used for automatic interruption one line, i.e. solve them out when such overload occurs.
Für einige mögliche Überlastungsfälle wird ein Magnetsystem zur Auslösung des Leitungsschutzschalters verwendet. Das Magnetsystem hat einen beweglichen Anker, der in Ruhelage teilweise in eine von dem Strom in der zu überwachenden Leitung fließenden Strom durchflossene Spule hineinragt. Wird der Strom in der Spule größer als ein vorbestimmter Auslösestrom, wird der Anker durch das entstehende Magnetfeld der Spule verschoben und löst über einen Stößel den Leitungsschutzschalter aus.For there will be some possible overload cases Magnetic system for triggering of the circuit breaker. The magnet system has one movable anchor, which at rest partially in one of the stream in the to be monitored Pipe flowing Current flowing through the coil protrudes. The current in the coil larger than a predetermined tripping current, the armature is displaced by the magnetic field of the coil and solve about one Pestle the Miniature circuit breaker off.
Weil die Spule stets von dem zu überwachenden Strom durchflossen ist, muss das Auslöseglied, d.h. Anker und Stößel, von einer Feder in einer definierten Ruhelage gehalten sein, um ein definiertes Ansprechen des Leitungsschutzschalters sicherzustellen und Fehlauslösungen zu vermeiden.Because the coil is always monitored Current has flowed through, the trigger element, i.e. Anchor and plunger, by a spring in a defined rest position to be a ensure a defined response of the circuit breaker and false triggers to avoid.
Folglich muss das Magnetsystem eine Mehrzahl verschiedener mechanischer Teile enthalten, um diese Funktionssicherheit zu gewährleisten. Diese Mehrzahl mechanischer Teile zusammenzufügen ist zeitaufwendig und folglich teuer.As a result, the magnet system must A variety of different mechanical parts are included to ensure this functional reliability to ensure. Assembling this plurality of mechanical parts is time consuming and consequent expensive.
Die Leitungsschutzschalter werden in großen Stückzahlen hergestellt, da nahezu sämtliche Stromkreise in Häusern, Fabriken und dgl. inzwischen durch solche Schalter abgesichert werden müssen.The circuit breakers are in large numbers manufactured because almost all circuits in houses, Factories and the like must now be protected by such switches.
Aus der
Die
In einer Vielzahl von Fällen erfolgt die Anpassung der Auslösecharakteristik dieser Magnetsysteme zum einen durch die Gestaltung der Spule, zum anderen auch durch die passende Wahl der Vorspannkraft. Dazu wird beispielsweise eine abgewandelte Feder verwendet.Done in a variety of cases the adjustment of the tripping characteristic of these magnet systems on the one hand through the design of the coil, on the other also through the right choice of preload. For example a modified spring used.
Folglich liegt der Erfindung die Aufgabe zugrunde, ein Magnetsystem zu schaffen, das mit einer geringeren Teilevielfalt die Veränderung der Auslösecharakteristik des Magnetsystems ermöglicht, sowie ein Montageverfahren dafür vorzuschlagen.Consequently, the invention is the Task to create a magnet system with a lower Variety of parts the change the tripping characteristic of the magnet system enables as well as an assembly process for it propose.
Diese Aufgabe wird hinsichtlich des Magnetsystems mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst, während die Aufgabe hinsichtlich des Verfahrens durch die Schritte des Anspruchs 7 gelöst wird.This task is carried out with regard to the Magnet system with the characterizing features of claim 1 solved, while the task with regard to the method by the steps of claim 7 solved becomes.
Gemäß der vorliegenden Erfindung ist der Einsatz, welcher ein Widerlager für die Feder bildet, derart gestaltet, dass er in zwei unterschiedlichen Positionen eingebaut werden kann, wobei die unterschiedlichen Einbaulagen jeweils unterschiedliche Federvorspannungen bewirken, weil der Abstand zwischen Einbauanschlag und Federwiderlager durch den Umschlag verändert werden kann.According to the present invention is the insert, which forms an abutment for the spring, such designed to be installed in two different positions can be, the different installation positions each have different spring preloads cause because of the distance between the installation stop and the spring abutment changed the envelope can be.
