Description
Überstromschalter mit elektromagnetischer Schnellauslösung und thermischer Zeitauslösung Die Erfindung bezieht sich auf einen überstromschalter mit elektromagnetischer Schnellauslösung und thermischer Zeitauslösung. Das Wesen der Erfindung besteht darin, daß an seinem dreischenkelib n Elektromagneten mit je einem am Mittelschenkel gelagerten leichten und schweren Anker hinter der Magnetspule der Strom eine Abzweigung über den schweren Anker, die Auslöseklinke und den Bimetallstresfen besitzt und eine hierzu parallele Abzweigung über den leichten Anker und einen von diesem gesteuerten öffnungskontakt den Bimetallstreifen kurzgeschlossen hält.Overcurrent switch with electromagnetic quick release and thermal time release The invention relates to an overcurrent switch with electromagnetic quick release and thermal time release. The essence of the invention is that on its three-legged electromagnet, each with a light and heavy armature mounted on the middle leg, behind the magnet coil, the current has a branch via the heavy armature, the release pawl and the bimetallic lever and a parallel branch via the light armature and an opening contact controlled by this keeps the bimetal strip short-circuited.
Durch diese Einrichtung wird (erreicht, daß der Thermostat während der normalen Belastung nicht vom Gesamtstrom durchflossen wird, so daß @er sich bei Dauerbetrieb nicht erwärmt. Brei den bekannten Einrichtungen, bei dienen der Thermostat idauernd vom Hauptstrom durchflossen wird, kann. es vorkommen, daß per bei Dauerbetrieb anspricht, ohne daß eine Überlastung vorhanden. war. Dieser Nachteil wird durch die Erfindung nun dadurch mrnni:eden, daß der Thermostat erst dann in den Hauptstromkreis ;eingeschaltet wixd, wenn eine Überlastung eintritt, während @er im normalen Betrieb im Nebenschluß liegt. Weiterhin wird durch diese Schaltung in Verbindung mit .dem dreischenkeligen Magnieten erreicht, daß der Thermostat bei Kurzsch3.uß nicht in Mitleidenschaft gezogen wird und dadurch gegen Zerstörung einen bessern Schutz -genießt.This device (ensures that the thermostat during the normal load is not traversed by the total current, so that @er himself not heated during continuous operation. Porridge the well-known facilities, at serve the Thermostat i the main current flows through continuously, can. it happens that by responds in continuous operation without an overload being present. was. This disadvantage is now by the invention mrnni: eden that the thermostat is only then in the main circuit; switched on when an overload occurs while @ he is shunted in normal operation. Further through this circuit in connection with .dem three-legged magnet rivets that the thermostat at Kurzsch3. Does not have to be affected and thus one against destruction better protection - enjoy.
Auf der Zeichnung ist eine beispielsweise schematische Darstellung der Erfindung gegeben.The drawing shows an example of a schematic representation given the invention.
Der Strom durchfließt die Spulea und den Körper ;des Magneten b und geht von hier einmal über den leichten Anker c, den Kontakt d nach e, dann über den Schalter k nach f. Der zweite Stromweg führt über den Anker g, die Klinke h, den Bimetallstreifen s nach , usw.The current flows through the coilea and the body; the magnet b and goes from here once over the light anchor c, the contact d to e, then over the switch k to f. The second current path leads via the armature g, the pawl h, the bimetallic strips s, etc.
Die Wirkungsweise ist folgende: Bei eintretendem Höchststrom wird der Anker c vom Magneten b angezogen, so daß der Kreis zwischen c und d unterbrochen ist. Nunmehr fließt der volle Strom über den Bimetallstreifcn i, der sich bei längerer Dauer der Überlastung so weit nach links bewegt, daß die Klinke h die Arretierung der Stange l freigibt, die unter der Einwirkung der Federn die Kontakte des Schalters k trennt.The mode of operation is as follows: When the maximum current occurs, the armature c attracted by the magnet b, so that the circle between c and d is interrupted is. Now the full current flows through the bimetallic strip i, which becomes longer with longer Duration of the overload moved so far to the left that the pawl h locks the rod l releases the contacts of the switch under the action of the springs k separates.
Bei eintretendem Kurzschluß oder kurzschlußähnlichen Überlastungen wird der Anker g des Magneten sofort angezogen und löst die Klinke h direkt aus.In the event of a short circuit or overload similar to a short circuit the armature g of the magnet is immediately attracted and triggers the pawl h directly.
Der Schalter kann z. B. .durch den Knopf tt wiedereingeschaltet werden. Es ist selbstverständlich, daß auch eine Freiauslösung angebracht werden kann.The switch can e.g. B.. Be switched on again by the button tt. It goes without saying that a trip-free mechanism can also be attached.
Die Einrichtung selbst eignet sich besonders auch für Installationsselbstschalter.The device itself is particularly suitable for self-contained installation switches.
