Description

Beschreibung description
Überlastauslöser, insbesondere für einen Leistungsschalter Die Erfindung betrifft einen Überlastauslöser, insbesondere für einen Leistungsschalter mit einem Metallstreifen aus mindestens zwei unterschiedlichen Metallarten, um welchen ein Heizleiter gewickelt ist. Die technischen Eigenschaften von Motor beziehungsweise Leis- tungsschutzgeräten bestehen unter Anderem darin, die Temperatur mittels gewickeltem Thermobimetall zu erfassen, die in den Strom führenden Zuleitungen zu überwachenden elektrischen Verbraucher angeordnet sind. Overload release, in particular for a circuit breaker The invention relates to an overload release, in particular for a circuit breaker having a metal strip of at least two different types of metal, around which a heating conductor is wound. Among other things, the technical characteristics of the motor or of the power protection devices consist in detecting the temperature by means of wound thermostatic bimetals which are arranged in the current-carrying supply lines to be monitored electrical consumers.
In elektromechanischen Schutzgeräten, insbesondere in Leistungsschaltern, werden Bimetall- beziehungsweise Trime- tallstreifen als Überlastauslöser verwendet. Um die gewünschten Auslösecharakteristiken zu erreichen, weisen die Metall- streifen in der Regel entweder eine Heizwicklung oder ein Heizpaket auf. In electro-mechanical protective devices, especially in circuit breakers, bimetallic or tri-metal strips are used as overload triggers. In order to achieve the desired tripping characteristics, the metal strips usually have either a heating coil or a heating package.
Bei Heizwicklungen handelt es sich um Metalldrähte oder Bänder, die um den Bimetallstreifen gewickelt sind. Zwischen Bi- metallstreifen und Heizwicklung befindet sich ein elektrischer Isolator, zum Beispiel Glasseidengewebe, um einen Kurz- schluss der einzelnen Heizleiterwicklungen zum Bimetallstreifen zu verhindern. Am oberen Ende des Bimetallstreifens sind Heizleiter und Bimetall miteinander verschweißt. Heater windings are metal wires or tapes wrapped around the bimetallic strip. Between the bimetal strip and the heating coil there is an electrical insulator, for example glass fiber fabric, in order to prevent a short-circuit of the individual heating conductor windings to the bimetallic strip. At the upper end of the bimetallic strip heating conductor and bimetal are welded together.
In elektromechanischen Schutzgeräten werden demgemäß Thermo- bimetallstreifen eingesetzt. Sind diese Strom durchflössen, das heißt direkt beheizt, so müssen sie im Gerät nicht nur mechanisch sondern auch elektrisch angebunden werden. Diese beiden Anbindungen werden mit einer Schweißung zwischen dem Thermobimetallstreifen und dem Metallteil realisiert. Mit diesem Metallteil wird der Thermobimetallstreifen im Gerät fixiert. Gleichzeitig wird der Strom über das Metallteil zum Thermobimetallstreifen herangeführt . In electro-mechanical protective devices, accordingly, bimetallic strips are used. If these currents are flowing through, ie directly heated, then they must be connected in the device not only mechanically but also electrically. These two connections are realized with a weld between the bimetallic strip and the metal part. With this metal part of the bimetallic strip is in the device fixed. At the same time, the current is supplied via the metal part to the bimetallic strip.
Bei Geräten für höhere Ströme wurde das oben beschriebene Problem aus Geräteerwärmung einerseits und fertigungs- und gerätetechnischen Hindernissen andererseits dadurch gelöst, dass für das Metallteil Kupfer plattierte Stahlwerkstoffe verwendet werden. Dieser Werkstoff kann mit den Thermobime- tallstreifen unter bestimmten Voraussetzungen gut verschweißt werden. Auf Grund des Stahlanteils ist der Werkstoff zum ei¬ nen ferromagnetisch und kann damit in den magnetischen Kreis eines Kurzschlussauslösers integriert werden. Zum Anderen liefert der Stahlanteil auch die geforderte Steifigkeit für das Metallteil. Die Dicke der Kupferplattierung wird dabei so gewählt, dass der Widerstand des Metallteils, und damit des¬ sen Erwärmung im Betrieb des Geräts, auf das geforderte Maß sinkt . In devices for higher currents, the above-described problem of device heating on the one hand and manufacturing and device-related obstacles on the other hand was solved by using copper-plated steel materials for the metal part. This material can be well welded with the thermobimetal strips under certain conditions. Due to the steel content, the material is ferromagnetic to egg ¬ nen and can thus be integrated into the magnetic circuit of a short-circuit release. On the other hand, the steel content also provides the required rigidity for the metal part. The thickness of the copper cladding is chosen so that the resistance of the metal part, and thus the ¬ sen heating during operation of the device, to the required level decreases.
Wirtschaftlich und technisch sinnvoll ist der Einsatz von Kupfer plattierten Stahlbändern zur Herstellung der Metallteile nur bis zu einer bestimmten Grenze. Eine wirtschaftli¬ che Begrenzung findet sich im Materialpreis, der ca. doppelt so hoch ist wie der für reine Kupferbänder gleicher Abmessung. Zusätzlich verteuernd wirkt in diesem Zusammenhang, dass die Stanzabfälle als Mischmetallschrot nur geringe Erlö¬ se erzielen. Damit ergibt sich der wirtschaftliche Zwang, konstruktiv den Einsatz dieses Materials im Gerät und den anfallenden Stanzabfall zu minimieren. Technisch begrenzt wird die Verwendung des Kupfer plattierten Stahlwerkstoffs bezogen auf den Strombereich der Geräte nach oben hin dadurch, dass mit steigendem Strombereich auch die Dicke der Kupferplattierung zunehmen muss. Gleichzeitig soll die Gesamtblechdicke des Materials jedoch gleich bleiben, damit keine separaten Fertigungsmittel wie Stanz-Biegewerkzeuge, Teilzuführungen, Montagevorrichtungen oder Schweißaufnahmen benötigt werden.Economically and technically useful is the use of copper-plated steel strips for the production of metal parts only up to a certain limit. Towards economically ¬ che limitation is found in the material price, which is about twice as high as the same for pure copper strips dimensions. In addition, more expensive in this context, that the punching waste as Mischmetallschrot achieve only low Erlö ¬ se. This results in the economic compulsion to constructively minimize the use of this material in the device and the resulting punching waste. The use of the copper-clad steel material with respect to the current range of the devices is technically limited at the top because the thickness of the copper cladding must increase with increasing current range. At the same time, however, the total sheet thickness of the material should remain the same, so that no separate means of production such as stamping and bending tools, part feeders, mounting devices or welding fixtures are needed.
Dies hat zur Folge, dass der Stahlanteil im Material abnimmt. Dies führt ab einer bestimmten Grenze zu Problemen beim Verbinden von Metallteil und Thermobimetallstreifen . Weiterhin verliert das Metallteil an benötigter Steifigkeit zur ausrei¬ chenden mechanischen Fixierung des Thermobimetallstreifens . Bei Geräten mit Kurzschlussauslösern wie zum Beispiel Leistungsschaltern, bewirkt der geringe Stahlanteil im Metallteil eine verringerte Funktion im Magnetkreis der Auslöserspule. This has the consequence that the steel content in the material decreases. This leads from a certain limit to problems when connecting metal part and bimetallic strip. Farther loses the metal part of the required rigidity for ausrei ¬ ing mechanical fixation of the bimetallic strip. In devices with short-circuit releases, such as circuit breakers, the low steel content in the metal part causes a reduced function in the magnetic circuit of the trigger coil.
Demgemäß besteht die Aufgabe der vorliegenden Erfindung darin, einen Überlastauslöser zu schaffen, der insbesondere für höhere Strombereiche einen optimierten Wärmehaushalt ermög- licht. Accordingly, the object of the present invention is to provide an overload release that makes an optimized heat balance possible, especially for higher current ranges.
Diese Aufgabe wird durch einen Überlastauslöser mit den Merkmalen des Patenanspruchs 1 gelöst. Vorteilhafte Aus- und Wei¬ terbildungen, welche einzeln oder in Kombination miteinander eingesetzt werden können, sind der Gegenstand der abhängigen Ansprüche . This object is achieved by an overload release with the features of patent claim 1. Advantageous embodiments and developments of Wei ¬ which may be used individually or in combination, are the subject of the dependent claims.
Erfindungsgemäß wird diese Aufgabe durch einen Überlastauslö¬ ser, insbesondere für einen Leistungsschalter gelöst mit ei- nem Metallstreifen aus mindestens zwei unterschiedlichen Metallarten, um welchen ein Heizleiter gewickelt ist. Die Erfindung zeichnet sich dabei dadurch aus, dass die mechanische und elektrische Anbindung des Metallstreifens vollständig oder teilweise getrennt ausgeprägt ist, so dass bei vollstän- diger Ausprägung kein Strom über die mechanische Anbindung des Metallstreifens fließt und bei teilweiser Ausprägung ein Teil des Stroms über die mechanische Anbindung fließt. According to the invention, this object is achieved by a Überlastauslö ¬ ser, in particular for a circuit breaker with a metal strip of at least two different types of metal, around which a heating element is wound. The invention is characterized in that the mechanical and electrical connection of the metal strip is completely or partially separated, so that when fully pronounced no current flows through the mechanical connection of the metal strip and part of the current through the mechanical partial Connection flows.
Die erfindungsgemäße Lösung besteht hier also darin, dass die mechanische und die elektrische Anbindung des Metallstrei¬ fens, insbesondere des Thermobimetallstreifens , getrennt wer¬ den. Dadurch lässt sich zum Einen ein optimierter Wärmehaushalt bewerkstelligen und zum Anderen sowohl fertigungs- als auch gerätetechnische Vorteile erzielen. Erfindungsgemäß kann die Trennung von mechanischer und elektrischer Anbindung vollständig oder teilweise ausgeprägt sein. Bei einer voll¬ ständigen Ausprägung fließt kein Strom über die mechanische Anbindung des Thermobimetallstreifens , bei teilweiser Ausprä- gung fließt ein Teil des Stroms über die mechanische Anbin- dung. Durch die erfindungsgemäße Trennung der beiden Anbin- dungen wird der Zwang zu einem Kompromiss aus mechanischen und elektrischen Forderungen aufgehoben. Die jeweilige Anbin- dung kann damit optimiert werden. The inventive solution consists here in the fact that the mechanical and the electrical connection of the Metallstrei ¬ fens, in particular the Thermobimetallstreifens separated ¬ the. As a result, on the one hand, it is possible to achieve an optimized heat balance and, on the other hand, to achieve both manufacturing and device-related advantages. According to the invention, the separation of mechanical and electrical connection can be fully or partially pronounced. In a fully continuous expression ¬ no current through the mechanical connection of the Thermobimetallstreifens flows with partial Ausprä- A portion of the current flows via the mechanical connection. The separation according to the invention of the two connections eliminates the need for a compromise between mechanical and electrical requirements. The respective connection can thus be optimized.
Die mechanische Anbindung und damit die Fixierung des Thermo- bimetallstreifens im Gerät erfolgt vorzugsweise über ein ein¬ faches Stahlteil. Die Schweißung zwischen dem Stahlteil und dem Thermobimetallstreifen ist auf Grund der Werkstoffpaarung auf einfache Weise möglich. Über die Schweißung fließt kein Strom beim Betrieb des Geräts. Über das Stahlteil wird der Thermobimetallstreifen im Oberteil des Leistungsschalters ex¬ akt mechanisch fixiert. The mechanical connection and the fixation of the thermal bimetallic strip in the device is preferably via a fold ¬ a steel part. The welding between the steel part and the bimetallic strip is possible due to the material pairing in a simple manner. There is no current flowing through the welding during operation of the device. About the steel part of the bimetallic strip is mechanically fixed ex ¬ akt in the upper part of the circuit breaker.
Die elektrische Anbindung des Thermobimetallstreifens wird erfindungsgemäß direkt ausgeführt, das heißt ohne Stromfüh¬ rung über das Metallteil, das den Thermobimetallstreifen mechanisch anbindet. Die Stromführung in der Strombahn des Schaltgeräts erfolgt in der Regel über einen Kupferleiter. Dieser wird erfindungsgemäß direkt mit dem Thermobimetall¬ streifen verbunden. Kupferleiter mit kleinem Querschnitt können direkt mit dem Thermobimetallstreifen verschweißt werden. Kupferleiter mit großem Querschnitt können nicht ohne Weite- res mit dem Thermobimetallstreifen verschweißt werden. Kupferleiter mit großem Querschnitt können an den Thermobimetallstreifen unter bestimmten Bedingungen gelötet werden. Dies kann mit einem dafür geeigneten Flussmittel und Lot erfolgen . The electrical connection of the bimetallic strip is carried out according to the invention directly, that is without Stromfüh ¬ tion on the metal part, which binds the bimetallic strip mechanically. The current in the current path of the switching device is usually via a copper conductor. This is inventively connected directly to the bimetallic strip ¬ . Copper conductors with a small cross-section can be welded directly to the bimetallic strip. Copper conductors with a large cross-section can not be readily welded to the bimetallic strip. Copper conductors with a large cross-section can be soldered to the bimetallic strip under certain conditions. This can be done with a suitable flux and solder.
Ein anderer Weg zum Löten der Kupferleitung an den Thermobimetallstreifen besteht darin, vorab wenigstens partiell eine mit einem nacharbeitsfreien Lot lötbare Oberfläche auf dem Thermobimetallstreifen zu erzeugen. Dort kann der Kupferlei- ter dann angelötet werden. Zur Erzeugung solcher lötbarerAnother way of soldering the copper wire to the bimetallic strip is to produce at least partially beforehand a surface solderable to a post-free solder on the bimetallic strip. There, the copper conductor can then be soldered. To produce such solderable
Oberflächen auf dem Thermobimetallstreifen gibt es verschiedene Vorgehensweisen. Bei Trimetallstreifen befindet sich im inneren eine Kupferseele, die freigelegt werden kann, die Oberfläche von Trimetallstreifen kann bis zur Kupferseele um¬ geschmolzen werden, es kann ein geeignetes Plättchen aufgeschweißt werden oder die Oberfläche des Thermobimetalls kann verkupfert werden. Surfaces on the bimetallic strip there are various approaches. In Trimetallstreifen located inside a copper soul, which can be exposed, the Surface of Trimetallstreifen can be melted ¬ to the copper core , it can be welded to a suitable plate or the surface of the bimetallic strip can be coppered.
Bei Schaltgeräten für höhere Strombereiche werden fast aus¬ schließlich so genannte Trimetalle zur Herstellung des Me¬ tallstreifens verwendet. Diese Trimetalle weisen eine Kupfer¬ seele auf, welche zwischen der Aktiv- und der Passivseite an- geordnet ist. Durch partielles Abtragen der Aktiv- oder Pas¬ sivseite kann die Kupferseele zum Beispiel durch Fräsen, Räu¬ men, Schleifen oder andere Fertigungsverfahren freigelegt werden. Damit entsteht eine Kupferoberfläche. Wird die Oberfläche des Trimetalls ausreichend stark umge¬ schmolzen, so wird Kupfer aus der Kupferseele in der Aktivbeziehungsweise Passivseite eingelagert. Dadurch befindet sich auch Kupfer an der Oberfläche, so dass dort gelötet wer¬ den kann. Das Umschmelzen kann beispielsweise durch einen La- serstrahl erfolgen. In switching devices for higher current ranges of Me ¬ tallstreifens be used almost from ¬ finally so-called Trimetalle for the preparation. These trimetals have a copper core , which is arranged between the active and the passive side. By partial removal of the active or Pas ¬ sivseite the copper core can be exposed, for example by milling, Räu ¬ men, grinding or other manufacturing processes. This creates a copper surface. If the surface of the Trimetalls sufficiently strong vice ¬ melted, so copper is deposited from the copper core in the asset or liability side. As a result, copper is also on the surface, so that there soldered ¬ who can. The remelting can be done, for example, by a laser beam.
Mit Hilfe eines Plättchens kann ebenfalls eine lötbare Ober¬ fläche auf dem Thermobimetallstreifen erzeugt werden. Das Plättchen hat die Eigenschaft, dass es sowohl mit dem Thermo- bimetallstreifen schweißbar, als auch mit dem Kupferleiter lötbar ist. Dabei kann das Plättchen entweder aus einem homogenen Werkstoff, wie beispielsweise Messing oder Bronze be¬ stehen oder aus einem mehrschichtigen Werkstoff wie zum Beispiel Kupfer beschichteter Stahl. Im Fall von Kupfer be- schichtetem Stahl wird das Plättchen mit der Stahlseite an den Thermobimetallstreifen geschweißt. Auf der außen liegenden Kupfer beschichteten Seite kann der Kupferleiter gelötet beziehungsweise anderweitig verbunden werden. Durch eine vollständige oder partielle Verkupferung der Ther- mobimetalloberfläche kann eine lötbare Oberfläche erzeugt werden. Das Verkupfern kann dabei anhand unterschiedlicher Methoden erfolgen: Es ist möglich, das Ausgangsmaterial für die Thermobimetallstreifen mit Kupfer zu plattieren oder galvanisch mit mindestens 10ym Kupfer zu beschichten. Es ist auch möglich, die gestanzten Thermobimetallstreifen vor dem Bewickeln galvanisch mit mindestens 10ym Kupfer zu beschich- ten. Denkbar ist auch, die gestanzten Thermobimetallstreifen vor dem Bewickeln durch so genanntes Kaltgasspritzen mit mindestens 10ym Kupfer zu beschichten. By means of a lamina a solderable top ¬ surface may also be formed on the bimetallic strip. The plate has the property that it is weldable both with the bimetallic strip and with the copper conductor solderable. In this case, the plate of either a homogeneous material, such as brass or bronze be ¬ stand or a multi-layer material such as copper coated steel. In the case of copper-coated steel, the plate with the steel side is welded to the bimetallic strip. On the outer copper coated side of the copper conductor can be soldered or otherwise connected. Complete or partial copper plating of the thermal metal surface can produce a solderable surface. The coppering can be done using different methods: It is possible, the starting material for clad the bimetallic strips with copper or coat them galvanically with at least 10microns of copper. It is also possible to galvanically coat the stamped bimetallic strips with at least 10 μm copper prior to winding. It is also conceivable to coat the stamped bimetallic strips with at least 10 μm copper prior to winding by so-called cold gas spraying.
Die vorliegende Erfindung besteht darin, die mechanische und elektrische Anbindung des Thermobimetallstreifens im Schalt¬ gerät bei Strom durchflossenen Thermobimetallstreifen zu trennen. Dadurch ist es möglich, einen gut leitenden Werkstoff mit einem Thermobimetall direkt zu verbinden. Das Me¬ tallteil zur mechanischen Anbindung des Thermobimetallstrei- fens kann für seine mechanischen und magnetischen Funktionen optimiert werden. Es kann als kostengünstiges Stahl-Bauteil ausgeführt werden und eröffnet damit gleichzeitig die Mög¬ lichkeit einer steifen Fixierung des Thermobimetalls . Dies ist aus gerätetechnischer Sicht von Bedeutung. Für die Ver- bindung von Thermobimetallstreifen mit dem fixierenden Stahl- Bauteil kann das gut automatisierbare Laserschweißverfahren eingesetzt werden, wodurch die Herstellungskosten verringert werden. Da die Verbindung nicht Strom führend ist, bestehen geringere Anforderungen an den verschweißten Querschnitt. Dies wirkt sich fertigungstechnisch und wirtschaftlich positiv aus. Die praktisch direkte Stromführung in den Thermobimetallstreifen ohne Zwischenschaltung eines weiteren Metallteils leistet einen wichtigen Beitrag zur Minimierung des elektrischen Widerstands und damit der Erwärmung in der The present invention is to separate the mechanical and electrical connection of the bimetallic strip in the switching ¬ device in current-traversed bimetallic strip. This makes it possible to directly connect a good conductive material with a bimetallic strip. The Me ¬ tallteil for mechanical connection of the Thermobimetallstrei- fens can be optimized for its mechanical and magnetic features. It can be designed as a cost-effective steel component and thus at the same time opens up the possi ¬ probability of a rigid fixation of the bimetallic strip. This is from a device technical point of importance. For the bonding of bimetallic strips with the fixing steel component, the easily automatable laser welding process can be used, whereby the manufacturing costs are reduced. Since the connection is not current leader, there are fewer requirements for the welded cross-section. This has a positive manufacturing and economic impact. The virtually direct current conduction in the bimetallic strip without the interposition of another metal part makes an important contribution to minimizing the electrical resistance and thus the heating in the
Strombahn außerhalb des Thermobimetallstreifens . Dies ist ge¬ rätetechnisch von großer Bedeutung, da auf Grund der vom Kunden gewünschten zunehmenden Leistungsdichte im Schaltgerät die Einhaltung der zulässigen Erwärmung eine Herausforderung darstellt. Die Trennung von mechanischer und elektrischer An- bindung des Thermobimetallstreifens im Schaltgerät ermöglicht die Einsparung von teurem Kupfer plattierten Material. Zudem kann die elektrische Anbindung verbessert werden. Damit erge¬ ben sich größere verschweißte, Strom tragende Querschnitte, so dass die Sicherheit bei Kurzschlussströmen und Überlast¬ strömen erhöht wird. Current path outside the bimetallic strip. This is ge ¬ councils technically important as maintaining the required warming is due to the customer's desired increase in power density in the switching device a challenge. The separation of mechanical and electrical connection of the bimetallic strip in the switching device makes it possible to save expensive copper-clad material. In addition, the electrical connection can be improved. Thus erge ¬, larger welded, electricity ben-bearing sections, so that the safety is increased in case of short-circuit currents and overload currents ¬.
