Description

Die Erfindung betrifft einen Haltemagnetauslöser, bei dem Jochkörper, Permanentmagnet, Auslöseanker, Erregerwicklung und Auslösefeder in einem hermetisch dichten, gegebenenfalls evakuierten oder mit einem Schutzgas, wie Stickstoff, gefüllten Gehäuse vorgesehen sind und bei dem die Leitungen zur Erregerwicklung dicht in das Innere des Gehäuses geführt sind.The invention relates to a holding magnet release, in which the yoke body, permanent magnet, release armature, excitation winding and release spring are provided in a hermetically sealed, possibly evacuated or filled with a protective gas, such as nitrogen, and in which the lines to the excitation winding lead tightly into the interior of the housing are.

Haltemagnetauslöser, wie sie z.B. in der AT-PS 278 954 beschrieben sind, werden üblicherweise insbesondere für Fehlerstrom-Schutzschalter in möglichst staubgeschützter Ausführung gebaut. Der Staubschutz ist aber nicht vollständig, da die Kraftübertragung vom und. zum Auslöseanker des Haltemagnetauslösers in Form eines Schiebers oder einer Achse Lagerluft aufweist, durch die Staub eindringen kann. Aus dem gleichen Grund ist auch kein Schutz vor Feuchtigkeit und chemisch aggressiven Gasen vorhanden. Die dadurch verursachten Korrosionen können ebenso wie Staub eine Funktionsunfähigkeit des Haltemagnetauslösers verursachen.Holding magnet triggers, e.g. are described in AT-PS 278 954, are usually built especially for residual current circuit breakers in the dust-protected version. The dust protection is not complete, however, since the power transmission from and. for the release anchor of the holding magnet release in the form of a slide or an axis bearing air through which dust can penetrate. For the same reason, there is no protection against moisture and chemically aggressive gases. The corrosions caused by this, like dust, can cause the magnetic release to not function properly.

Ein Auslöse-Relais in einem hermetisch dichten Gehäuse unterzubringen, ist aus der AT-PS 279 712 bekannt. Die Steuerstange dieses Auslöse-Relais wird mit Hilfe eines Faltenbalges durch das Gehäuse nach außen geführt.A trigger - Relais be housed in a hermetically sealed housing, is known from AT-PS 279,712. The control rod of this release relay is guided through the housing with the help of a bellows.

Aus der EU-OS O 026 804 ist ein hermetisch geschlossener permanentmagnetischer Auslöser für Fehlerstrom-Schutzschalter bekannt. Bei diesem Haltemagnetauslöser ist im Gehäuse. eine elastisch verformbare Kraftübertragungszone vorgesehen, über welche die Bewegungen des Ankers nach außen übertragen werden.From the EU-OS O 026 804 a hermetically sealed permanent magnetic trigger for fault current is - breakers known. This holding magnet release is in the housing. an elastically deformable power transmission zone is provided, via which the movements of the armature are transmitted to the outside.

Beiden bekannten Vorschlägen ist der Nachteil gemeinsam, daß sie elastisch verformbare Bauteile verwenden müssen. Diese elastisch verformbaren Bauteile behindern die Bewegungen, so daß die Auslöseempfindlichkeit der Haltemagnetauslöser beeinträchtigt wird. Zum anderen stellen elastisch verformbare Faltenbälge und gewellte Wandbereiche stets Schwachstellen dar, die zu Undichtheiten führen.The disadvantage of both known proposals is common, that they have to use elastically deformable components. These elastically deformable components hinder the movements, so that the trigger sensitivity of the holding magnet trigger is impaired. On the other hand, elastically deformable bellows and corrugated wall areas are always weak points that lead to leaks.

Der Erfindung liegt die Aufgabe zugrunde, einen Haltemagnetauslöser der.eingangs genannten Gattung anzugeben, der tatsächlich vor dem Eindringen von Staub, Feuchtigkeit und aggressiven Gasen geschützt ist und ohne elastisch verformbare Bauteile auskommt, über welche die Bewegungen des Ankers übertragen werden. Erfindungsgemäß wird dies dadurch erreicht, daß der Auslöseanker über mindestens eine Magnetkupplung mit einem außerhalb des Gehäuses angeordneten Außenhebel gekuppelt ist, wobei eine Hälfte der Permanentmagnetkupplung innerhalb des Gehäuses und die andere Hälfte der Permanentmagnetkupplung außerhalb des Gehäuses angeordnet ist.The invention has for its object to provide a magnetic release of the type mentioned, which is actually protected against the ingress of dust, moisture and aggressive gases and does not require any elastically deformable components via which the movements of the armature are transmitted. According to the invention this is achieved in that the release armature is coupled via at least one magnetic coupling to an outer lever arranged outside the housing, one half of the permanent magnet coupling being arranged inside the housing and the other half of the permanent magnetic coupling being arranged outside the housing.

Dadurch, daß beim erfindungsgemäßen Haltemagnetauslöser die Kraftübertragung vom und zum Auslöseanker mit Hilfe mindestens einer Permanentmagnetkupplung erfolgt, entfallen die bei den bekannten Haltemagnetauslösern unumgänglichen Durchführungen (Faltenbälge) beweglicher Teile durch das Gehäuse des Haltemagnetauslösers und die dadurch bedingte Gefahr von Undichtigkeiten.The fact that in the holding magnet release according to the invention the power transmission from and to the release armature takes place with the aid of at least one permanent magnet coupling, the inevitable lead-throughs (bellows) of moving parts through the housing of the holding magnet release and the consequent risk of leaks are eliminated in the known holding magnet releases.

Weitere Einzelheiten und Merkmale der Erfindung ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung des in der Zeichnung schematisch wiedergegebenen Ausführungsbeispieles. Es zeigt

  • Figur 1 einen Haltemagnetauslöser und
  • Figur 2 den Haltemagnetauslöser aus Figur 1 mit abgefallenem Auslöseanker.
Further details and features of the invention emerge from the subclaims and the following description of the exemplary embodiment shown schematically in the drawing. It shows
  • 1 shows a holding magnet release and
  • Figure 2 shows the magnetic release from Figure 1 with abge falling release anchor.

Ein in Figur 1 dargestellter Haltemagnetauslöser besitzt ein mindestens zweischichtiges Joch 1 mit einer Erregerwicklung 2, einem Permanentmagnet 3, einem Auslöseanker 4 mit einem Ankerhebel 5 sowie eine Auslösefeder 6.A holding magnet release shown in FIG. 1 has an at least two-layer yoke 1 with an excitation winding 2, a permanent magnet 3, a release armature 4 with an armature lever 5 and a release spring 6.

Bei stromloser Erregerwicklung 2 wird der Auslöseanker 4 entgegen der Zugwirkung der Auslösefeder 6 durch den Permanentmagnet 3 am Joch 1 festgehalten. Fließt hingegen durch die Erregerwicklung 2 Strom, so wird der Permanentfluß geschwächt und der Auslöseanker 4 fällt bei ausreichender Schwächung vom Joch 1 ab. Der Auslöseanker 4 bewegt einen Kupplungsstift 7 und dieser eine Permanentmagnetkupplung 8, die aus vier Permanentmagneten 8a, 8b, 8c und 8d, einem die Permanentmagnete 8b und 8c tragenden Innenhebel 9 und einem die Permanentmagnete 8a und 8d tragenden, nicht dargestellten Außenhebel besteht. Außer den beiden Permanentmagneten 8a und 8d und dem sie tragenden Außenhebel befinden sich alle vorgenannten Bauteile in einem hermetisch dichten Gehäuse 10 aus magnetisch nicht leitfähigem Werkstoff.When the excitation winding 2 is de-energized, the trip armature 4 is held against the pulling action of the trip spring 6 by the permanent magnet 3 on the yoke 1. If, on the other hand, current flows through the field winding 2, the permanent flux is weakened and the tripping armature 4 falls from the yoke 1 if the weakening is sufficient. The trigger armature 4 moves a coupling pin 7 and this a permanent magnet coupling 8, which consists of four permanent magnets 8a, 8b, 8c and 8d, an inner lever 9 carrying the permanent magnets 8b and 8c and an outer lever, not shown, carrying the permanent magnets 8a and 8d. In addition to the two permanent magnets 8a and 8d and the outer lever carrying them, all of the aforementioned components are located in a hermetically sealed housing 10 made of magnetically non-conductive material.

Figur 2 zeigt den Haltemagnetauslöser mit abgefallenem Auslöseanker 4. Bei richtiger Dimensionierung und Polung der Permanentmagnete 8a, 8b, 8c und 8d folgt der Außenhebel mit geringem Schlupf jeder Drehung des Innenhebels 9. Die Bewegung des Außenhebels kann z.B. zum Auslösen des Schaltschlosses eines nicht gezeigten Fehlerstrom-Schutzschalters herangezogen werden.FIG. 2 shows the holding magnet release with the release armature 4 fallen off. With the correct dimensioning and polarity of the permanent magnets 8a, 8b, 8c and 8d, the outer lever follows each rotation of the inner lever 9 with slight slip. The movement of the outer lever can e.g. be used to trigger the switch lock of a residual current circuit breaker, not shown.

Für die Rückstellung des Haltemagnetauslösers wird der Außenhebel gedreht, der Innenhebel 9 folgt mit geringem Schlupf und führt mit Hilfe des Kupplungsstiftes 7 den Auslöseanker 4 an das Joch 1 zurück, wobei die. Auslösefeder 6 wieder gespannt wird.To reset the holding magnet release, the outer lever is rotated, the inner lever 9 follows with little slip and guides the release armature 4 back to the yoke 1 with the aid of the coupling pin 7, the. Release spring 6 is tensioned again.

Zur Erreichung eines geringen Schlupfes in der Magnetkupplung 8 werden die Spalte zwischen den Permanentmagneten 8a und 8b bzw. 8c und 8d durch eine zumindest in diesem Bereich dünnwandige und/oder gewölbte Ausführung des Gehäuses 10 klein gehalten und eventuell Innensowie Außenhebel als magnetischer Rückschluß für den Permanentfluß ausgebildet.In order to achieve a small slip in the magnetic coupling 8, the gaps between the permanent magnets 8a and 8b or 8c and 8d are kept small by an at least in this area thin-walled and / or curved design of the housing 10 and possibly inside and outside lever as a magnetic yoke for the permanent flux educated.

Die hermetische Dichtheit wird z.B. durch Zulöten eines zweiteiligen Gehäuses und eingelötete Glasdurchführungen 1 für die Erregerwicklung 2 vervollständigt.The hermetic tightness is e.g. completed by soldering a two-part housing and soldered glass bushings 1 for the excitation winding 2.

Innerhalb des hermetisch dichten Gehäuses 10 kann sich Luft oder ein Schutzgas, wie Stickstoff oder eine Flüssigkeit, z.B. ein Siliconöl, befinden. Letzteres erweist sich als vorteilhaft, wenn eine größere Ansprechzeit des Haltemagnetauslösers gewünscht wird, etwa um die Empfindlichkeit eines Fehlerstrom-Schutzschalters gegenüber Stoßströmen zu reduzieren. Die Flüssigkeit wirkt in diesem Fall als Dämpfungsmedium. Eine weitere Möglichkeit ist die Evakuierung des hermetisch dichten Gehäuses 10.Air or a protective gas such as nitrogen or a liquid, e.g. a silicone oil. The latter proves to be advantageous if a longer response time of the holding magnet release is desired, for example in order to reduce the sensitivity of a residual current circuit breaker to surge currents. In this case, the liquid acts as a damping medium. Another possibility is the evacuation of the hermetically sealed housing 10.

Durch die Anordnung der vier Permanentmagneten 8a, 8b, 8c und 8d, wie in Figur 1 und 2 gezeigt, wirken auf die Achsen des Innen- bzw. Außenhebels keine radialen Zugkräfte. Die Kupplungsteile sind auf einfache Weise ausbalanciert und damit die Permanentmagnetkupplung gegenüber Erschütterungen unempfindlich.Due to the arrangement of the four permanent magnets 8a, 8b, 8c and 8d, as shown in FIGS. 1 and 2, no radial tensile forces act on the axes of the inner or outer lever. The coupling parts are easily balanced, making the permanent magnet coupling insensitive to vibrations.

Nimmt man eine radiale Zugkraft und die damit verbundenen Reibungsverluste in Kauf, so können zwei Permanentmagnete, z.B. die Permanentmagnete 8a und 8b, entfallen.If you accept a radial pulling force and the associated friction losses, two permanent magnets, e.g. the permanent magnets 8a and 8b are eliminated.

Es ist auch möglich, mit einem einzigen Permanentmagnet auszukommen, wenn diesem ein magnetisch leitfähiger Teil, wie z.B. Weicheisen, gegenübergestellt wird. Der zu erwartende erhöhte, Schlupf einer solchen Kupplung kann durch verbesserte Rückführung des Permanentflusses wieder reduziert werden. Als weitere Ausführungsform für die Permanentmagnetkupplung kommt eine Ausführung mit zwei Permanentmagneten in Frage, denen zwei Weicheisenteile gegenüberstehen, wodurch wieder keine radialen Zugkräfte auftreten.It is also possible to get by with a single permanent magnet if this has a magnetically conductive part, such as soft iron. The expected increased slip of such a clutch can be reduced again by improved feedback of the permanent flow. As a further embodiment for the permanent magnet coupling, an embodiment with two permanent magnets comes into question, which are opposed by two soft iron parts, as a result of which no radial tensile forces occur again.

Der Aufbau des erfindungsgemäßen,.hermetisch dichten Haltemagnetauslösers mit Permanentmagnetkupplung kann gegenüber der in den Figuren 1 und 2 dargestellten Ausführungsform noch vereinfacht werden, indem auf den Kupplungsstift 7 verzichtet und der Ankerhebel 5 so umgestaltet wird, daß er auch die Funktion des Innenhebels 9 der gezeigten Ausführungsform übernimmt. Bei dieser Ausführungsform trägt der beispielsweise als gleicharmiger Hebel ausgebildete Ankerhebel 5 an einem oder beiden seiner Enden Permanentmagnete, denen außerhalb des Gehäuses die am nicht gezeigten Außenhebel angeordneten Permanentmagnete oder Weicheisenteile gegenüberstehen. Es ist aber auch eine Ausführungsform denkbar, bei welcher der Ankerhebel 5 an einem oder beiden seiner Enden einen Weicheisenteil trägt, dem die außerhalb des Gehäuses 10 liegenden Magnete des Außenhebels gegenüberliegen.The structure of the hermetically sealed holding magnet release with permanent magnet coupling according to the invention can be simplified compared to the embodiment shown in FIGS. 1 and 2 by dispensing with the coupling pin 7 and redesigning the armature lever 5 so that it also functions as the inner lever 9 of the one shown Embodiment takes over. In this embodiment, the armature lever 5, which is designed, for example, as an equal arm, carries permanent magnets at one or both of its ends, which are opposed by the permanent magnets or soft iron parts arranged on the outer lever (not shown) outside the housing. However, an embodiment is also conceivable in which the armature lever 5 carries a soft iron part at one or both of its ends, which the magnets of the outer lever lying outside the housing 10 lie opposite.
