Abstract
Description
Die Erfindung bezieht sich auf einen permanentmagnetischen Auslöser für Fehlerstrom-Schutzschalter gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a permanent magnetic release for residual current circuit breakers according to the preamble of
Es ist allgemein üblich, Auslöser der eingangs geschilderten Art in einem Gehäuse unterzubringen. Derartige Gehäuse haben hierbei die Aufgabe zu erfüllen, die Halterung und Abdeckung der Auslöser zu übernehmen. Es ist aber auch möglich, daß die Gehäuse für Auslöser derart gestaltet sind, daß sie die Funktionen der Auslöser aktiv unterstützen. Ein derartiges Gehäuse für ein Auslöserrelais ist aus der DE-PS 20 29 607 bekannt. Die Vielfältigkeit der Gehäuse für diese kleinen elektrischen Geräte wird weitgehend durch die gedrängte Bauweise, die diesen Geräten meistens zu eigen ist, bestimmt. Die Schutzfünktion der bekannten Gehäuse beschränkt sich im wesentlichen auf die Abdeckung nach außen, um Einflüsse durch Staub und Verschmutzung weitgehend auszuschalten. Einflüsse der umgebenden Atmosphäre lassen sich bei den bekannten Gehäusen jedoch nicht verhindern, so daß die Funktionssicherheit der in diesen Gehäusen befindlichen Geräte nicht immer gewährleistet ist. Besonders kritisch ist hierbei eine hohe Luftfeuchtigkeit.It is common practice to house triggers of the type described in the introduction in a housing. Such housings have the task of carrying out the mounting and covering of the triggers. But it is also possible that the housing for triggers are designed such that they actively support the functions of the triggers. Such a housing for a trigger relay is known from DE-PS 20 29 607. The diversity of the housings for these small electrical devices is largely determined by the compact construction, which is common to these devices. The protective function of the known housing is essentially limited to the cover to the outside in order to largely eliminate the effects of dust and dirt. Influences of the surrounding atmosphere cannot be prevented in the known housings, so that the functional safety of the devices located in these housings is not always guaranteed. High air humidity is particularly critical.
Der Erfindung liegt daher die Aufgabe zugrunde, einen Auslöser mit Gehäuse zu schaffen, der unabhängig von atmosphärischen Einflüssen voll funktionsfähig ist.The invention is therefore based on the object of providing a trigger with a housing which is fully functional regardless of atmospheric influences.
Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen konstruktiven Maßnahmen gelöst.This object is achieved by the constructive measures specified in the characterizing part of
Die mit der Erfindung erzielten Vorteile bestehen darin, daß durch den Einschluß des Auslösersystems in .ein hermetisch dichtes Gehäuse der ungünstige Einfluß der Atmosphäre verhindert wird, und mit Hilfe der Kraftübertragungszone als Bindeglied zwischen dem Anker innerhalb des Gehäuses und des hierzu korrespondierenden Übertragungshebels außerhalb des Gehäuses die volle Arbeitsfähigkeit des Auslösersystems hergestellt wird.The advantages achieved by the invention are that the inclusion of the trigger system in a hermetically sealed housing prevents the unfavorable influence of the atmosphere, and with the aid of the force transmission zone as a link between the armature inside the housing and the corresponding transmission lever outside the housing the trigger system is fully functional.
Vorteilhafte Ausgestaltungen des Gegenstandes des Anspruchs 1 sind den Unteransprüchen zu entnehmen.Advantageous embodiments of the subject matter of
So betreffen die Ansprüche 2 bis 6 die Ausgestaltung und Besonderheiten der Kraftübertragungszone, der Anspruch 7 das Innere des Gehäuses, die Ansprüche 8 bis 11 die verschiedenen Möglichkeiten eines hermetisch geschlossenen Gehäuses, das nach Anspruch 12 erforderlichenfalls mit einer Schutzgasfüllung versehen werden kann. Schließlich beschreibt der Anspruch 13 die zu treffenden Maßnahmen für die Anschlußleitungen der Spulenwicklung.Thus claims 2 to 6 relate to the design and special features of the power transmission zone, claim 7 the interior of the housing, claims 8 to 11 the various possibilities of a hermetically sealed housing which can be provided with a protective gas filling if necessary. Finally,
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen:
- Fig. 1 einen hermetisch geschlossenen permanentmagnetischen Auslöser in Ruhestellung, in Seitenansicht, teilweise im Schnitt
- Fig. 2 diesen Auslöser im ausgelösten Zustand
- Fig. 3 eine Kraftübertragungszone in Seitenansicht, im Ausschnitt
- Fig. 4 diese Kraftübertragungszone in Draufsicht, im Ausschnitt.
- Fig. 1 shows a hermetically closed permanent magnetic release in the rest position, in side view, partly in section
- Fig. 2 this trigger in the triggered state
- Fig. 3 shows a power transmission zone in side view, in the detail
- Fig. 4, this power transmission zone in plan view, in the detail.
Nach den Fig. 1 und 2 befindet sich ein Auslöserrelais 1 in einem Gehäuse 2. Das Gehäuse ist topfartig ausgebildet und wird nach Einsetzen des Auslöserrelais mit einem Deckel (nicht dargestellt) hermetisch verschlossen.1 and 2 there is a
Das Auslöserrelais 1 weist ein U-förmiges Joch 11 und einen Anker 12 auf. Einer der Schenkel des Jochs ist von einer Spulenwicklung 13 umgeben, deren Enden als Anschlußleitungen durch die Gehäusewand geführt sind. Unterhalb des Jochs befindet sich ein Permanentmagnet 14.The
Das Gehäuse 2 besitzt eine Kraftübertragungszone 21, die das Bindeglied zwischen dem Anker 12 und einem Übertragungshebel 22 herstellt, der drehbeweglich außen am Gehäuse befestigt ist. Die Kraftübertragungszone ist dünnwandiger als die übrigen Gehäusewände gestaltet und in Höhe des Angriffspunktes des Ankers beidseitig mit Verstärkungselementen 23, wie Verstärkungsnocken bzw. stiftartigen Ansätzen, ausgestattet. Konzentrisch zu den Verstärkungselementen 23 befinden sich Sicken 24. Eine derartige Gestaltung der Kraftübertragungszone gestattet eine Expansion dieses Bereichs nach beiden Seiten. Der Übertragungshebel besitzt in diesem Bereich gleichfalls einen Verstärkungsnocken 25, der zusätzlich einstellbar gemacht werden kann. Das Auslöserrelais ist im Gehäuse durch Haltevorrichtungen 26, wie Haltenocken, Führungsschlitze oder Stege, gehaltert.The
Im Ruhezustand des Auslöserrelais, wie in Fig. 1 gezeigt, wird der Anker durch die Kraft des Permanentmagneten auf den Polschuhen des Jochs gehalten. Im Auslösefall wird die Kraft des Permanentmagneten durch die Kraft des magnetischen Feldes der Spulenwicklung aufgehoben und der Anker kann von den Polschuhen abheben. Im Fall eines Klappankers (Fig. 2) vollführt er eine Drehbewegung und stößt mit seinem über die Kippkante des Polschuhes ragenden Ende an eines der Verstärkungselemente der Kraftübertragungszone. Durch die Drehbewegung des Ankers gibt die Kraftübertragungszone nach und wird nach außen gedrückt. Das außenliegende Verstärkungselement der Kraftübertragungszone trifft auf einen Verstärkungsnocken am Übertragungshebel, der nun aus seiner Ruhestellung um seine Befestigungsachse bewegt wird.In the idle state of the trip relay, as shown in Fig. 1, the armature is held by the force of the permanent magnet on the pole pieces of the yoke. In the event of tripping, the force of the permanent magnet is canceled by the force of the magnetic field of the coil winding and the armature can lift off the pole pieces. In the case of a hinged anchor (FIG. 2), it performs a rotary movement and its end, which projects over the tilting edge of the pole piece, strikes one of the reinforcing elements of the force transmission zone. The force transmission zone gives way due to the rotary movement of the armature and is pushed outwards. The outer reinforcement element of the power transmission zone meets a reinforcement cam on the transmission lever, which is now moved about its fastening axis from its rest position.
In den Fig. 3 und 4 sind die Verstärkungselemente 23 und die hierzu konzentrischen Sicken 24 zu ersehen.3 and 4, the reinforcing
