Abstract

Two yoke metal sheets are held at a given spacing and are fixed at a mean spacing, to determine the magnetic properties of the actuator, after application of contacting points. Before the contact points are applied, the capacitance formed by the yoke metal sheets and the air gap is periodically determined and compared with a preset rated value. The yoke metal sheet spacing, at the attained rated value, is held constant. An Independent claim is included for the manufacturing mechanism.

Description

TECHNISCHES GEBIETTECHNICAL AREA

Bei der Erfindung wird ausgegangen von einem Verfahren zur Herstellung eines zwei feststehende Bleche enthaltenden Jochs eines vorzugsweise in einem Fehlerstrom-Schutzschalter (Fl-Schalter) einsetzbaren Magnetauslösers nach dem Oberbegriff von Patentanspruch 1. Ein solches Joch dient der Führung eines konstanten magnetischen Dauerflusses von einem Dauermagneten zu einem beweglichen Anker des Magnetauslösers. Wird der magnetische Dauerfluss durch ein von einer Auslösespule abgegebenes und etwa auf einen Fehlerstrom zurückzuführendes Signal geschwächt, so wird der von einer vorgespannten Feder belastete Anker vom Joch abgehoben und löst dann ein Kraftübertragungsglied aus. Bei einem Fl-Schalter wirkt das Kraftübertragungsglied auf ein Schaltschloss, welches ein Öffnen der Kontaktanordnung des Fl-Schalters bewirkt.The invention is based on a method for producing a two fixed sheets containing yokes, preferably in one Residual current circuit breaker (Fl switch) insertable magnetic release after the Preamble of claim 1. Such a yoke is used to guide a constant magnetic flux from one permanent magnet to one movable armature of the magnetic release. Will the permanent magnetic flux through one emitted by a trip coil and approximately to a fault current The signal to be fed back is weakened by a preloaded spring loaded anchor is lifted from the yoke and then triggers a force transmission element. In the case of a Fl switch, the force transmission element acts on a key switch, which causes an opening of the contact arrangement of the Fl switch.

STAND DER TECHNIKSTATE OF THE ART

Die Erfindung nimmt auf einen Stand der Technik Bezug, wie er in EP 0786 789 A1 beschrieben ist. Ein in diesem Stand der Technik angebenes Joch für einen in einen Fl-Schalter eingebauten Magnetauslöser weist im wesentlichen zwei feststehend angeordnete Jochbleche auf, welche mittels stegförmig ausgebildeter Verbindungspunkte zusammengefügt sind, und zwischen denen sich als magnetisch schlecht leitendes Diaphragma ein ca. 20 bis 100 µm dicker Luftspalt befindet. Der Luftspalt trennt die beiden Jochbleche unter Bildung eines magnetischen Widerstandes vorgegebener Grösse und verhindert so, dass der von einem Dauermagneten in den magnetischen Kreis eingespeiste magnetische Dauerfluss kurzgeschlossen wird. The invention relates to a prior art, as described in EP 0786 789 A1 is described. A yoke specified in this prior art for one in one Fl-switch built-in magnetic trigger essentially has two fixed arranged yoke plates, which by means of web-shaped Connection points are joined together, and between them are magnetic poorly conductive diaphragm is an air gap approx. 20 to 100 µm thick. The Air gap separates the two yoke sheets to form a magnetic one Resistance of a predetermined size and thus prevents that of one Permanent magnet permanent magnetic flux fed into the magnetic circuit is short-circuited.

Für die Funktionssicherheit des Magnetauslösers ist es entscheidend, dass seine Ausschaltleistung in einem vorgegebenen schmalen Bereich mit einer Schwankungsbreite von typischerweise 10 bis 20 % liegt. Die Ausschaltleistung hängt ab von den Abmessungen des Luftspaltes und dem Verhältnis von Jochblechzu Luftspaltfläche. Daher ist die Einhaltung einer Dickentoleranz des Luftspaltes innerhalb des vorgenannten Schwankungsbereichs notwendig. Bei einem für einen Magnetauslöser typischen Luftspalt mit einer mittleren Dicke von ca. 40 µm entspricht dies einer Dicken- bzw. Abstandstolerenz von ca. ± 4 µm. Die verwendeten Jochbleche weisen einen aufgebogenen Schenkel und eine verhältnismässig unregelmässige Aussenkontur auf. Ihre Geradheits- und Dickentoleranz liegt praktisch eine Grössenordnung über der geforderten Toleranz des Luftspaltes, so dass eine vorgängige kostenintensive Bearbeitung der Jochbleche im Bereich des Luftspaltes, beispielsweise durch Läppen, und die Verwendung von Abstandshaltern erforderlich erscheinen.For the functional reliability of the magnetic release, it is crucial that its Breaking capacity in a predetermined narrow range with a Fluctuation range is typically 10 to 20%. The breaking capacity depends on the dimensions of the air gap and the ratio of the yoke plate Air gap area. Therefore, compliance with a thickness tolerance of the air gap necessary within the above-mentioned fluctuation range. One for one Magnetic release typical air gap with an average thickness of approx. 40 µm this corresponds to a thickness or spacing tolerance of approx. ± 4 µm. The The yoke sheets used have a bent leg and one relatively irregular outer contour. Your straightness and Thickness tolerance is practically an order of magnitude above the required tolerance of the air gap, so that a previous cost-intensive processing of the Yoke plates in the area of the air gap, for example by lapping, and the Use of spacers may appear necessary.

Bei der Herstellung des vorbekannten Jochs werden die beiden Jochbleche üblicherweise jeweils in eine von zwei vertikal übereinander angeordneten und gegeneinander verschiebbaren Klemmbacken fixiert. Die Bleche werden sodann nach Zwischenlage von Abstandshaltern unter Bildung des Luftspaltes gegeneinander geführt und durch Anbringen von Verbindungspunkte in einem Laserschweissverfahren fixiert. Die Abstandshalter werden entfernt. Der zwischen den beiden Jochblechen liegende magnetische Widerstand vorgebener Grösse ist dann durch die Luftschicht zwischen den Jochblechen und die geometrischen Abmessungen der als Schweissstellen ausgebildeten Verbindungspunkte bestimmt.The two yoke sheets are used in the manufacture of the known yoke usually each in one of two vertically one above the other and fixed against each other movable jaws. The sheets are then after interposing spacers with formation of the air gap against each other and by attaching connection points in one Laser welding process fixed. The spacers are removed. The between is the magnetic resistance of the given size lying on the two yoke plates then through the air layer between the yoke sheets and the geometric Dimensions of the connection points designed as welding points are determined.

Die Verwendung der Abstandshalter erschwert und verlangsamt den Herstellprozess ganz wesentlich. Zudem bedarf es nachfolgend zusätzlicher Reinigungs- und Bearbeitungsschritte, welche den Herstellprozess zusätzlich verlangsamen und verteuern. The use of the spacers complicates and slows down the manufacturing process very essential. In addition, additional cleaning and Processing steps that slow down the manufacturing process and make it more expensive.

KURZE DARSTELLUNG DER ERFINDUNGSUMMARY OF THE INVENTION

Der Erfindung, wie sie in den Patentansprüchen angegeben ist, liegt die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art zu schaffen, mit dem in einfacher und kostengünstiger Weise Joche hoher Präzision gefertigt werden können, sowie eine Vorrichtung zur Durchführung dieses Verfahrens anzugeben.The object of the invention is as set out in the claims is based on creating a method of the type mentioned at the beginning with which yokes of high precision can be manufactured in a simple and cost-effective manner can specify, as well as a device for performing this method.

Das erfindungsgemässe Verfahren erfasst mit der Messung der Kapazität des durch die beiden Jochbleche und den dazwischenliegenden Luftspalt gebildeten Kondensators indirekt auch die Dicke des Luftspaltes. Wegen der Analogie von elektrischem und magnetischem Feld wird damit auch der von der Dicke des Luftspaltes abhängige und für die Auslöseleistung des das Joch enthaltenden Magnetauslösers ausschlaggebende magnetische Fluss erfasst. Durch Verändern des Luftspaltvolumens infolge Verschiebens der Jochbleche senkrecht zueinander werden so bei der Kapazitätsmessung mit hoher Genauigkeit Angaben über den mittleren Jochblechabstand und damit auch über die Grösse des magnetischen Flusses gewonnen, welche eine äusserst präzise Herstellung des Jochs ermöglichen.The method according to the invention captures by measuring the capacity of the the two yoke plates and the air gap between them The capacitor also indirectly affects the thickness of the air gap. Because of the analogy of electric and magnetic field is also the thickness of the Air gap dependent and for the release power of the containing the yoke Magnetic trigger detects pivotal magnetic flux. By changing of the air gap volume due to displacement of the yoke plates perpendicular to each other In this way, information about the average yoke plate distance and thus also about the size of the magnetic River, which is an extremely precise manufacture of the yoke enable.

Die beim erfindungsgemässe Verfahren verwendete Kapazitätsmessung berücksichtigt die unruhige Oberflächentopographie der Jochbleche und liefert so ein direktes Abbild der magnetischen Kopplung zwischen den Jochblechen. Sie ist unempfindlich gegen äussere Störeinflüsse, wie Temperatur, Luftfeuchtigkeit, Luftdruck, Verschmutzung, Alterung und/oder EMV-Störungen, weist eine hohe Auflösung (<1nm) und ein eindeutiges Signal-Antwort-Verhalten auf und kann wegen kurzer Einschwingzeiten (ca. 200 µs) sehr rasch ausgeführt werden.The capacitance measurement used in the method according to the invention takes into account the restless surface topography of the yoke sheets and thus delivers direct image of the magnetic coupling between the yoke plates. she is insensitive to external interference, such as temperature, humidity, Air pressure, pollution, aging and / or EMC interference has a high Resolution (<1nm) and a clear signal-response behavior and can be due to short settling times (approx. 200 µs) can be carried out very quickly.

Die erfindungsgemässe Vorrichtung zur Durchführung des Verfahrens zeichnet sich durch hohe Flexibilität und Taktzeiten im Sekundenbereich, beispielsweise 4 s, aus. Dies ist vor allem eine Folge der raschen Durchführbarkeit der Kapazitätsmessung und der guten Verwendbarkeit der ermittelten Kapazität zur Bildung einer Stellgrösse in einem Regelkreis, dessen Regelgrösse die Dicke des Luftspalts bzw. der mittlere Abstand der Jochbleche ist. The device according to the invention for carrying out the method is distinguished through high flexibility and cycle times in the range of seconds, for example 4 s. This is primarily due to the rapid feasibility of the capacity measurement and the good usability of the determined capacity to form a manipulated variable in a control loop, the controlled variable of which is the thickness of the air gap or the mean The distance between the yoke plates is.

    • WEGE ZUR AUSFÜHRUNG DER ERFINDUNGWAYS OF CARRYING OUT THE INVENTION

    In allen Zeichnungen beziehen sich gleiche Bezugszeichen auf gleichwirkende Teile. Die in den Figuren 1 und 2 dargestellte Vorrichtung weist zwei vertikal übereinander angeordnete Klemmbacken 1 und 2 auf, von denen die untere Klemmbacke 1 feststehend und die obere Klemmbacke 2 in vertikaler Richtung (Doppelpfeil) verschieblich angeordnet ist. Hierbei kann der Weg, den die Klemmbacke 2 während eines Bewegungsvorgangs in vertikaler Richtung zurückgelegt hat, mit Hilfe eines nicht dargestellten Wegaufnahmesensors erfasst werden.In all drawings, the same reference numbers refer to parts with the same effect. The device shown in Figures 1 and 2 has two vertically one above the other arranged jaws 1 and 2, of which the lower jaw 1 stationary and the upper jaw 2 in the vertical direction (double arrow) is slidably arranged. Here, the path that the jaw 2 during a movement in the vertical direction, using a displacement sensor not shown are detected.

    Eine Dreipunktauflage 3 ist vor der Inbetriebnahme der Vorrichtung (Position A) leer und wird zu Beginn des Herstellverfahrens mit einem Jochblech 4 beladen (Position B). Mittels eines als Stift ausgebildeten Positionierelementes 5 wird das Jochblech 4 mit Kraft gegen die Dreipunktauflage 3 gedrückt (Position C), und unter Beibehaltung des Drucks in der unteren Klemmbacke 1 fixiert und ausgerichtet (Position D). Das Positionierelement 5 wird dann weggefahren (Position E) und die Herstellvorrichtung sodann mit einem zweiten Jochblech 6 beladen (Position F). Dieses Jochblech wird mit dem Positionierelement 5 mit Kraft gegen das auf der Dreipunktauflage 3 abgestützte Jochblech 4 gedrückt (Position G) und unter Beibehaltung des Drucks in der oberen Klemmbacke 2 fixiert (Position H). Durch nachfolgendes zwei- oder gegebenenfalls auch mehrfaches impulsartiges Drücken des Jochblechs 6 mit dem Positionierelement 5 wird eine besonders vorteilhafte Ausrichtung des Jochblechs 6 und zugleich eine Nullung des mittleren Abstandes zwischen den beiden Jochblechen 4 und 6 erreicht (Position I).A three-point support 3 is empty before starting up the device (position A) and is loaded with a yoke plate 4 at the beginning of the manufacturing process (item B). The yoke plate 4 is formed by means of a positioning element 5 designed as a pin pressed with force against the three-point support 3 (position C), and while maintaining the pressure in the lower jaw 1 fixed and aligned (position D). The Positioning element 5 is then moved away (position E) and the manufacturing device then load with a second yoke plate 6 (position F). This yoke sheet will with the positioning element 5 with force against that on the three-point support 3 supported yoke plate 4 pressed (position G) and while maintaining the pressure in the upper jaw 2 fixed (position H). By following two or if necessary, multiple pulse-like pressing of the yoke plate 6 with the Positioning element 5 becomes a particularly advantageous alignment of yoke plate 6 and at the same time zeroing the mean distance between the two Yoke plates 4 and 6 reached (position I).

    Nach dem Entfernen des Positionierelementes 5 werden sodann von oben bzw. unten je zwei Signalanschlüsse S1, S3 bzw. S2, S4 eines in Fig.3 angedeuteten Kapazitätsmessgerätes 7 an die Jochbleche 4 und 6 geführt (Position J). Die zwei Signalanschlüsse S1 und S2 dienen der Zuführung eines messwerterzeugenden Signals an die Jochbleche 4 und 6, wohingegen die beiden Signalanschlüsse S3 und S4 der Aufnahme eines messwertproportionalen Signals von den Jochblechen 4 und 6 dienen. Die der Aufnahme des messwertproportionalen Signals dienenden Signalanschlüsse S3 und S4 wirken auf einen Fig.3 entnehmbaren Regler 8 eines Regelkreises 9.After removing the positioning element 5, two signal connections S 1 , S 3 and S 2 , S 4 of a capacitance measuring device 7 indicated in FIG. 3 are then guided to the yoke plates 4 and 6 (position J) from above and below. The two signal connections S 1 and S 2 serve to supply a signal generating a measured value to the yoke plates 4 and 6, whereas the two signal connections S 3 and S 4 serve to receive a signal proportional to the measured value from the yoke plates 4 and 6. The signal connections S 3 and S 4 used to receive the signal proportional to the measured value act on a controller 8 of a control circuit 9 which can be removed from FIG.

    Die obere Klemmbacke 2 wird nun unter Bildung eines Luftspaltes 10 zwischen den beiden Jochblechen 4 und 6 nach oben gefahren (Position K). Während des Fahrens wird periodisch die Kapazität des durch die Jochbleche 4, 6 und des dazwischenliegenden Luftspaltes 10 gebildeten Kondensators in Abhängigkeit vom Jochblechabstand periodisch gemessen. Aus Fig.3 ist ersichtlich, dass die gemessene Kapazität Cist in jeder Messperiode im Regelkreis 9 mit einem vorgebenen zwischen einer oberen Grenze CSollmax und einer unteren Grenze CSollmin liegenden Kapazitätssollwert verglichen wird. Stimmt Cist mit diesem Sollwert nicht überein, so wird an eine nicht dargestellte Vorrichtung zum Ändern des Abstandes der beiden Klemmbacken 1, 2 ein als Stellgrösse wirkendes Signal y abgegeben, durch welches die Klemmbacke 2 weitergeführt und so der Abstand zwischen den beiden Jochblechen 4, 6 verändert wird (vgl. Fig.3: Abstandskorrektur y). Stimmen schliesslich gemessene Kapazität und Sollwert überein, so wird die Kapazitätsmessung beendet und der beim Sollwert vorhandene Jochblechabstand zunächst konstant gehalten.The upper jaw 2 is now moved upwards to form an air gap 10 between the two yoke plates 4 and 6 (position K). During driving, the capacitance of the capacitor formed by the yoke plates 4, 6 and the air gap 10 between them is periodically measured as a function of the distance between the yoke plates. It can be seen from FIG. 3 that the measured capacitance C is compared in the control circuit 9 in each measurement period with a predetermined capacitance setpoint lying between an upper limit C setpoint max and a lower limit C setpoint min . If C is not in agreement with this target value, a signal y acting as a manipulated variable is output to a device (not shown) for changing the distance between the two clamping jaws 1, 2, through which the clamping jaw 2 continues and thus the distance between the two yoke plates 4, 6 is changed (see Fig. 3: distance correction y). If the measured capacitance and the target value finally match, the capacity measurement is ended and the yoke plate distance at the target value is initially kept constant.

    Die Signalanschlüsse des Kapazitätsmessgerätes werden nun weggefahren (Position L). Es wird sodann durch Verschieben der Klemmbacke 2 eine Abstandskorrektur ySchrumpfung vorgenommen (Position M und Fig.3). Bei dieser Korrektur wird durch Veränderung des zunächst konstant gehaltenen Jochblechabstands (Position L) um einen vorgegebenen Korrekturwert ein definierter Montagewert des Jochblechabstandes erreicht. Ist dieser Montagewert eingestellt, so können die beiden Jochbleche 4, 6 durch Anbringen von Verbindungspunkten 11 (Position O) fixiert werden. Der Korrekturwert ySchrumpf ist derart bestimmt, dass sich beim Anbringen der Verbindungspunkte 11 ein angestrebter mittlerer Jochblechabstand einstellt.The signal connections of the capacitance meter are now moved away (position L). A distance correction y shrinkage is then carried out by moving the clamping jaw 2 (position M and FIG. 3). With this correction, a defined installation value of the yoke plate distance is achieved by changing the initially constant yoke plate distance (position L) by a predetermined correction value. If this installation value is set, the two yoke plates 4, 6 can be fixed by attaching connection points 11 (position O). The correction value y shrinkage is determined in such a way that a desired mean yoke plate distance is established when the connection points 11 are attached.

    Die Verbindungspunkte 11 werden mittels einer Fügevorrichtung 12 randseitig an den Jochblechen 4, 6 angebracht. Werden die Verbindungspunkte 11 in einem Schweissverfahren, vorzugsweise in einem Laserschweissverfahren, angebracht, so sollte der zunächst konstant gehaltene Jochblechabstand durch den Korrekturwert ySchrumpf vergrössert werden, um so die beim Schweissen auftretende Abstandsverringerung infolge Schrumpfung zu kompensieren (Position N). Es kann aber auch der zunächst konstant gehaltene Jochblechabstand (Position L) als Montageabstand dienen. Der Kapazitätssollwert ist dann derart zu bestimmen, dass sich der mittlere Jochblechabstand beim nachfolgenden Anbringen der Verbindungspunkte 11 einstellt. Beim Anbringen der Verbindungspunkte 11 in einem Schweissverfahren sollte der Kapazitätssollwert kleiner sein als der Kapazitätswert des Kondensators sein, da dann die beim Schweissen auftretende Schrumpfung berücksichtigt ist.The connection points 11 are attached to the edge of the yoke plates 4, 6 by means of a joining device 12. If the connection points 11 are attached in a welding process, preferably in a laser welding process, the yoke sheet spacing, which was initially kept constant, should be increased by the correction value y shrinkage , so as to compensate for the reduction in distance due to shrinkage that occurs during welding (position N). However, the yoke plate distance (position L), which was initially kept constant, can also serve as the installation distance. The nominal capacity value is then to be determined in such a way that the mean yoke plate distance is established when the connection points 11 are subsequently attached. When attaching the connection points 11 in a welding process, the capacitance setpoint should be smaller than the capacitance value of the capacitor, since the shrinkage occurring during welding is then taken into account.

    Anstelle eines Kapazitätsmessgerätes 7 kann auch eine andere Vorrichtung zur Ermittlung der Kapazität Cist des von den Jochblechen 4, 6 und dem dazwischenliegenden Luftspalt 10 gebildeten Kondensators verwendet werden. Mit Vorteil kann eine solche Vorrichtung einen mit den Signalanschlüsse S1, S2, S3, S4 verbundenen Resonanzfrequenzmesser sowie einen dem Resonanzfrequenzmesser nachgeschalteten Computer aufweisen. Der Resonanzfrequenzmesser misst dann die Resonanzfrequenz eines die Kapazität Cist und eine Induktivität vorbestimmter Grösse enthaltenden Schwingkreises. Der Computer ermittelt dann aus der vom Resonanzfrequenzmesser gemessenen Resonanzfrequenz die Kapazität Cist, welche dann - wie zuvor beschrieben wurde - mit dem Kapazitätssollwert verglichen wird. Instead of a capacitance measuring device 7, another device for determining the capacitance C ist of the capacitor formed by the yoke sheets 4, 6 and the air gap 10 located therebetween can be used. Such a device can advantageously have a resonance frequency meter connected to the signal connections S 1 , S 2 , S 3 , S 4 and a computer connected downstream of the resonance frequency meter. The resonant frequency meter then measures the resonant frequency of the capacitance C and an inductance of predetermined size containing resonant circuit. The computer then determines the capacitance C is from the resonance frequency measured by the resonance frequency meter, which is then - as described above - compared to the capacitance setpoint.
