Abstract
Description
Die Erfindung betrifft einen thermischen Auslöser gemäß dem Oberbegriff des Anspruches 1.The The invention relates to a thermal release according to the preamble of the claim 1.
Bei einem Leitungsschutzschalter oder einem Motorschutzschalter sind Auslöser für Kurzschlussströme und Überströme vorgesehen. Die Erfindung befasst sich hier mit einem thermischen Auslöser, der bei Überströmen auslösen soll.at a circuit breaker or a motor protection switch trigger intended for short-circuit currents and overcurrents. The invention is concerned here with a thermal release, the to trigger at overcurrents.
Normalerweise verwendet man für thermische Auslöser Thermobimetalle, die in Streifenform ausgebildet sind und die an einem Ende eingespannt sind, wobei sie sich am anderen Ende ausbiegen und auf eine Verklinkungsstelle in einem Schaltschloss einwirken, so dass diese entklinkt und eine Kontaktstelle bleibend geöffnet werden. Anstatt eines Thermobimetalls kann natürlich auch ein Streifen aus einer Formgedächtnislegierung verwendet werden.Usually one uses for thermal trigger Thermobimetals, which are formed in strip form and the clamped at one end, where they turn out at the other end and act on a Verklinkungsstelle in a switch lock, so that it unlocks and a contact point are permanently opened. Instead of a bimetallic strip can of course also a strip a shape memory alloy be used.
Bei dem Schalter S2 der Firma ABB Stotz Kontakt GmbH, Heidelberg, ist das Thermobimetall an dem Magnetjoch durch Verschweißen befestigt.at the switch S2 of the company ABB Stotz contact GmbH, Heidelberg, is attached the bimetallic strip to the magnetic yoke by welding.
Aufgabe der Erfindung ist es, einen thermischen Auslöser der eingangs genannten Art weiter zu verbessern, so dass der thermische Auslöser auf einfacherer Weise in den Leitungsschutzumfang eingesetzt und montiert werden kann.task The invention is a thermal release of the aforementioned Kind further improve, so that the thermal trigger on more easily inserted and mounted in the scope of protection can be.
Diese Aufgabe wird erfindungsgemäß gelöst durch die Merkmale des Anspruches 1.These The object is achieved by the features of claim 1.
Erfindungsgemäß ist demgemäß der Träger in Vertiefungen im Gehäuse fixiert und einerseits mit der Anschlussklemme und andererseits mit einer Zuführleitung verbunden, wobei am Träger eine Abkantung vorgesehen ist, mit der eine Stirnkante gebildet ist, gegen die das Thermobimetall mit seinem feststehenden Ende fest geschweißt ist.According to the invention, the carrier is accordingly in recesses in the case fixed and on the one hand with the terminal and on the other hand with a supply line connected to the carrier a fold is provided, with which a front edge is formed, against the thermostatic bimetal with its fixed end welded is.
Wenn hier und im folgenden der Begriff „Thermobimetall" verwendet wird, so wird unmittelbar damit auch ein Auslöser aus einem Formgedächtnismaterial darunter verstanden.If here and in the following the term "bimetallic bimetal" is used, this immediately becomes a trigger from a shape memory material understood by that.
In vorteilhafter Ausgestaltung der Erfindung kann der Träger U-förmig ausgebildet und das Thermobimetall mit einem der Schenkel fest und elektrisch leitend verbunden sein.In Advantageous embodiment of the invention, the carrier can be U-shaped and the thermostatic bimetal with one of the legs fixed and electrical be conductively connected.
Dabei
bestehen zwei Möglichkeiten:
Die
Schenkel der U-Form verlaufen in Richtung zum ausbiegbaren Ende
des Thermobimetalls oder in entgegen gesetzte Richtung. Im ersten
Fall ist im Bereich des Grundes der U-Form eine senkrecht zur Schenkelerstreckung
verlaufende, die U-Form überragende
Abkantung ausgeklinkt, an deren Stirnseite das Thermobimetall fest
geschweißt
ist.There are two possibilities:
The legs of the U-shape extend in the direction of the deflectable end of the bimetallic strip or in the opposite direction. In the first case, in the region of the bottom of the U-shape, a bend running perpendicular to the extension of the leg, which projects beyond the U-shape, is unlatched, at the end face of which the bimetallic strip is firmly welded.
Im anderen Fall ist das Thermobimetall mit einem Schenkel verbunden, wogegen am anderen Ende die Anschlussklemme angebracht ist. Dabei ist der Schenkel nach außen abgebogen und das Thermobimetall an die abgebogene Stirnkante fest verschweißt.in the In another case, the bimetallic strip is connected to a leg, whereas at the other end the terminal is attached. there is the thigh outward bent and the bimetallic welded to the bent front edge firmly.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind den weiteren Unteransprüchen zu entnehmen.Further advantageous embodiments of the invention are the further dependent claims remove.
Anhand der Zeichnung, in der einige Ausführungsbeispiele der Erfindung dargestellt sind, sollen die Erfindung sowie weitere vorteilhafte Ausgestaltungen und Verbesserungen der Erfindung und weitere Vorteile näher erläutert und beschrieben werden.Based the drawing, in which some embodiments of the invention are shown, the invention and further advantageous Embodiments and improvements of the invention and further advantages explained in more detail and to be discribed.
