Description

Die vorliegende Erfindung betrifft eine Schalteranordnung gemäss dem Oberbegriff des Anspruchs 1.The present invention relates to a switch arrangement according to the preamble of claim 1.

Eine solche Schalteranordnung ist aus der US-PS 4,587,390 bekannt. Diese weist ein, einen Federkraftantrieb enthal­tendes Gehäuse auf, auf dem drei rohrförmige Isoliertrag­rahmen stehend angeordnet sind. In jedem Isoliertragrah­men ist eine Vakuumschaltröhre befestigt, deren Kontakte mit je einem, den jeweiligen Isoliertragrahmen in radia­ler Richtung durchdringenden Anschlussleiter verbunden sind. Im Gehäuse des Federkraftantriebes sind zwei paral­lele, seitlich voneinander beabstandete Schilder vorgese­hen, an welchen die Antriebsteile des Federkraftantriebes gelagert sind. Jeder bewegbare Kontakt der Vakuumschalt­röhren ist über je ein Gestänge mit dem für alle Pole ge­meinsamen Abtriebsglied des Federkraftantriebes wirkver­bunden. Diese Schalteranordnung weist viele Einzelteile auf, und ist in ihrer Konstruktion und Montage aufwendig.Such a switch arrangement is known from US Pat. No. 4,587,390. This has a housing containing a spring force drive, on which three tubular insulating support frames are arranged standing. A vacuum interrupter is fastened in each insulating support frame, the contacts of which are connected to a connecting conductor which penetrates the respective insulating support frame in the radial direction. Two parallel, laterally spaced plates are provided in the housing of the spring drive, on which the drive parts of the spring drive are mounted. Each movable contact of the vacuum interrupters is operatively connected via a linkage to the output element of the spring force drive, which is common to all poles. This switch arrangement has many individual parts and is complex to construct and assemble.

Weiter ist aus der EP-PS 0 060 054 eine Vakuumschalteran­ordnung mit einem fahrbaren Gestell bekannt. An diesem Gestell ist ein einstückiger Isoliertragrahmen rückwärts befestigt, welcher drei nebeneinander angeordnete, nach vorne offene Ausnehmungen aufweist, in welchen je eine Vakuumschaltröhre befestigt ist. Am Gestell ist weiter ein Gehäuse befestigt, in welchem ein Antrieb angeordnet ist, dessen Abtriebsteil über je ein Gestänge mit dem be­wegbaren Kontakt jeder Vakuumschaltröhre wirkverbunden ist, wobei ein Doppelhebel jedes Gestänges an Fortsätzen des Isoliertragrahmens gelagert ist. Obwohl dieser Iso­liertragrahmen mehrere Funktionen übernimmt, ist die Kon­struktion der gesamten Schalteranordnung immer noch auf­wendig.Furthermore, a vacuum switch arrangement with a movable frame is known from EP-PS 0 060 054. A one-piece insulating support frame is fastened to the back of this frame, which has three recesses which are arranged next to one another and are open to the front and in each of which a vacuum interrupter is fastened. A housing is also attached to the frame, in which a drive is arranged, the driven part of which is operatively connected to the movable contact of each vacuum interrupter via a linkage is, wherein a double lever of each linkage is mounted on extensions of the insulating support frame. Although this insulating support frame performs several functions, the construction of the entire switch arrangement is still complex.

Es ist daher Aufgabe der vorliegenden Erfindung, ein Schalteranordnung gemäss dem Oberbegriff des Anspruchs 1 zu schaffen, welche in ihrem Aufbau einfach ist, wenig Teile aufweist und mit wenig Aufwand herstellbar ist.It is therefore an object of the present invention to provide a switch arrangement according to the preamble of claim 1 which is simple in construction, has few parts and can be produced with little effort.

Diese Aufgabe wird durch die Merkmale des Kennzeichens des Anspruchs 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.

Der Isoliertragrahmen ist somit nicht nur ein isolieren­des Tragelement für die Vakuumschaltröhre, sondern er ist auch ein fester Bestandteil des Antriebes. Der Antrieb und der Isoliertragrahmen bilden somit eine voneinander nicht mehr trennbare Funktionseinheit.The insulating support frame is therefore not only an insulating support element for the vacuum interrupter, but it is also an integral part of the drive. The drive and the insulating support frame thus form a functional unit that can no longer be separated from one another.

Eine besonders stabile Ausführungsform, bei welcher die in einem Federkraftantrieb auftretenden Kräfte besonders gut beherrschbar sind, ist im Anspruch 2 angegeben.A particularly stable embodiment, in which the forces occurring in a spring force drive can be controlled particularly well, is specified in claim 2.

Die Herstellung der Schalteranordnung wird durch die im Anspruch 3 angegebenen Merkmale besonders vereinfacht. Dabei werden bei der Produktion des Isoliertragrahmens die Lagerelemente, wie Lagerschalen, Anschläge, Zapfen usw. direkt am Lagerungsteil ein- oder angegossen, ein- oder angespritzt bzw. um- oder angeschäumt.The manufacture of the switch arrangement is particularly simplified by the features specified in claim 3. In the production of the insulating support frame, the bearing elements, such as bearing shells, stops, pegs, etc., are molded or molded directly on the bearing part, injected or molded, or encapsulated or foamed.

Bei einer Ausbildungsform gemäss Anspruch 4 müssen die Gestänge nur geringe Kräft aufnehmen, was eine einfache Konstruktion erlaubt, und eine polweise Montage wird er­möglicht.In a form of training according to claim 4, the Booms absorb only little force, which allows a simple construction, and a pole-wise assembly is possible.

Eine besonders herstellmässig und wirtschaftlich vorteil­hafte Ausbildungsform ist im Anspruch 5 angegeben. Jeder Pol weist einen identischen Isoliertragrahmen auf, wobei aber die Antriebsteile des Federkraftantriebes vorzugs­weise nicht an allen Lagerungsteilen aller Isoliertrag­rahmen gelagert sind. So ist es beispielsweise vorteil­haft, Antriebsteile am Lagerungsteil des Isoliertragrah­mens eines einzigen Poles anzuordnen, und das Abtriebs­glied zusätzlich an Lagerungsteilen der andern Pole abzu­stützen. Eine Ausführungsform gemäss Anspruch 5 erlaubt aber auch, Antriebsteile an Lagerungsteilen von Isolier­tragrahmen verschiedener Pole zu lagern.A particularly manufacturing and economically advantageous form of training is specified in claim 5. Each pole has an identical insulating support frame, but the drive parts of the spring force drive are preferably not mounted on all bearing parts of all the insulating support frames. For example, it is advantageous to arrange drive parts on the bearing part of the insulating support frame of a single pole, and to additionally support the driven member on bearing parts of the other poles. An embodiment according to claim 5 also allows drive parts to be mounted on bearing parts of insulating support frames of different poles.

Besonders stabile Ausführungsformen sind mit den in den Ansprüchen 6 und 7 angegebenen Merkmalen erzielbar.Particularly stable embodiments can be achieved with the features specified in claims 6 and 7.

Eine Ausbildungsform gemäss Anspruch 8 erlaubt, dass so­wohl die Vakuumschaltröhren, die Uebertragungsgestänge sowie der Federkraftantrieb am Isoliertragrahmen befe­stigt, bzw. gelagert sind, was die Anzahl der benötigten Teile verkleinert, und Montage und Justierarbeiten ver­einfacht.An embodiment according to claim 8 allows that both the vacuum interrupters, the transmission linkage and the spring force drive are attached to the insulating support frame or are mounted, which reduces the number of parts required, and simplifies assembly and adjustment work.

Die Erfindung wird nun anhand eines in der Zeichnung dar­gestellten Ausführungsbeispiels näher beschrieben. Es zeigen rein schematisch:

  • Fig. 1 in perspektivischer Darstellung, und
  • Fig. 2 und 3 in Draufsicht bzw. Seitenansicht eine vereinfacht dargestellte dreipolige Schalteranordnung.
The invention will now be described with reference to an embodiment shown in the drawing. It shows purely schematically:
  • Fig. 1 in perspective, and
  • 2 and 3 in plan view and side view of a three-pole switch arrangement shown in simplified form.

Die dreipolige Schalteranordnung 10 weist drei identi­sche, einstückige Isoliertragrahmen 12, 12′ auf, welche auf einem plattenförmigen, fahrbaren, metallenen Gestell 14 befestigt sind. Jeder Isoliertragrahmen 12, 12′ be­steht aus einem, auf dem Gestell 14 stehenden, rohrför­migen Isoliergehäuse 16 und zwei zueinander parallelen, voneinander seitlich ungefähr um den Durchmesser des Iso­liergehäuses 16 beabstandeten, in ungefähr tangentialer Richtung vom Isoliergehäuse 16 wegragenden Isolierwand­elementen 18.The three-pole switch arrangement 10 has three identical, one-piece insulating support frames 12, 12 ', which are fastened to a plate-shaped, movable, metal frame 14. Each insulating support frame 12, 12 'consists of a standing on the frame 14, tubular insulating housing 16 and two mutually parallel, spaced from each other laterally about the diameter of the insulating housing 16, in approximately tangential direction from the insulating housing 16 projecting insulating wall elements 18th

Zwischen den Isolierwandelementen 18 des mittleren Iso­liertragrahmens 12′ ist ein in seinem grundsätzlichen Aufbau allgemein bekannter Federkraftantrieb 20 vorgese­hen, dessen Abtriebswelle 22 aber an den Isolierwandele­menten 18 aller drei Isoliertragrahmen 12, 12′ gelagert ist. Wie dies insbesondere in der Fig. 2 schematisch an­gedeutet ist, sind aber auch die weiteren Antriebsteile 24, wie Wellen, Klinken, Federn usw. des Federkraftan­triebes 20 an den Isolierwandelementen 18 des Isolier­tragrahmens 12′ gelagert bzw. abgestützt. Dabei ist zu beachten, dass an den Isolierwandelementen 18 aller Iso­liertragrahmen 12, 12′ die Lagerelemente 26, wie Zapfen, Löcher, Lagerschalen und dergleichen für die Antriebstei­le 24 angeformt bzw. eingegossen oder eingespritzt sind. Es werden aber nur alle Lagerelemente 26 des mittleren Isoliertragrahmens 12′ für den Federkraftantrieb 20 benö­tigt, während von den an den Isoliertragrahmen 12 vorge­ sehenen Lagerelementen 26 nur jene für die Abtriebswelle 22 gebraucht werden.Between the insulating wall elements 18 of the central insulating support frame 12 ', a spring force drive 20, which is generally known in its basic construction, is provided, the output shaft 22 of which, however, is mounted on the insulating wall elements 18 of all three insulating support frames 12, 12'. As is indicated schematically in particular in FIG. 2, but also the other drive parts 24, such as shafts, pawls, springs, etc. of the spring force drive 20 on the insulating wall elements 18 of the insulating support frame 12 'are supported or supported. It should be noted that on the insulating wall elements 18 of all the insulating support frames 12, 12 ', the bearing elements 26, such as pegs, holes, bearing shells and the like for the drive parts 24 are molded or cast or injected. However, only all bearing elements 26 of the central insulating support frame 12 'are required for the spring-loaded drive 20, while the ones on the insulating support frame 12 are preferred see bearing elements 26 only those for the output shaft 22 are used.

In jedem Isoiergehäuse 16 ist eine Vakuumschaltröhre 28 angeordnet, welche je von einem, im Isoliergehäuse 16 eingegossenen ersten Anschlussleiter 30 gehalten ist, welcher elektrisch mit dem feststehenden Schaltkontakt 32 der Vakuumschaltröhre 28 verbunden ist (s. insbesondere Fig. 3). Der jeweils zweite, ebenfalls im Isoliergehäuse 16 eingegossene, Anschlussleiter 34 weist einen schema­tisch dargestellten Schleifkontakt 36 auf, welcher mit dem bewegbaren Schaltkontakt 38 der Vakuumschaltröhre 28 elektrisch verbunden ist. Die Anschlussleiter 30, 34 ste­hen auf der, den Isolierwandelementen 18 abgewandten Sei­te über die Isoliergehäuse 16 vor. Daran können bei­spielsweise nicht dargestellte Teile von Trennkontakten befestigt sein, um die Schalteranordnung 10 mit den in Schaltzellen angeordneten weiteren Trennkontaktteilen in oder ausser Verbindung zu bringen.A vacuum interrupter 28 is arranged in each insulating housing 16, each of which is held by a first connecting conductor 30 cast in the insulating housing 16, which is electrically connected to the fixed switching contact 32 of the vacuum interrupter 28 (see in particular FIG. 3). The second connecting conductor 34, which is also cast in the insulating housing 16, has a schematically illustrated sliding contact 36, which is electrically connected to the movable switching contact 38 of the vacuum interrupter 28. The connecting conductors 30, 34 protrude on the side facing away from the insulating wall elements 18 via the insulating housing 16. Parts of isolating contacts (not shown) can be attached to this, for example, in order to bring the switch arrangement 10 into or out of connection with the further isolating contact parts arranged in switch cells.

Der bewegbare Schaltkontakt 38 jeder Vakuumschaltröhre 28 ist über ein Gestänge 40 mit der Abtriebswelle 22 des Fe­derkraftantriebes 20 wirkverbunden. Etwa mittig der bei­den Isolierwandelemente 18 jedes Isoliertragrahmens 12, 12′ ist an der Abtriebswelle 22 ein Hebel 42 drehfest an­geordnet, dessen freies Ende über eine Schubstange 44 mit dem einen Hebelarm eines am Isoliertragrahmen 12, 12′ schwenkbar gelagerten Winkelhebels 46 verbunden, dessen anderer Hebelarm mittels einer Isolierstange 48 mit dem bewegbaren Schaltkontakt 38 in Wirkverbindung steht.The movable switch contact 38 of each vacuum interrupter 28 is operatively connected via a linkage 40 to the output shaft 22 of the spring force drive 20. Approximately in the middle of the two insulating wall elements 18 of each insulating support frame 12, 12 ', a lever 42 is arranged in a rotationally fixed manner on the output shaft 22, the free end of which is connected via a push rod 44 to the one lever arm of an angle lever 46 pivotably mounted on the insulating support frame 12, 12', the other lever arm is operatively connected to the movable switching contact 38 by means of an insulating rod 48.

Wie dies besonders aus der Fig. 1 gut ersichtlich ist, bilden die Isolierwandelemente 18 des Isoliertragrahmens 12′ auch die Seitenwände des Federkraftantriebs 20, dessen Front- und Rückwand sowie Deckel von einem abnehmbaren Wandelement 50 gebildet ist, an dessen Frontteil Oeffnun­gen für Betätigungs- und Anzeigeelemente vorgesehen sind.As can be seen particularly well from FIG. 1, form the insulating wall elements 18 of the insulating support frame 12 'also the side walls of the spring drive 20, the front and rear wall and cover of which is formed by a removable wall element 50, on the front part of which openings for actuating and display elements are provided.

Auch diese Betätigungs- und Anzeigelemente sowie die in einem Federkraftantrieb 20 benötigten Steuerelemente, wie Hilfsschalter, Schützen und dergleichen sowie Reihenklem­men, um diese Steuerelemente mit Steuer- und Rückmelde­leitungen zu verbinden, können an den Isolierwandelemen­ten 18 befestigt sein.These actuating and display elements as well as the control elements required in a spring-loaded drive 20, such as auxiliary switches, contactors and the like, as well as terminal blocks in order to connect these control elements to control and feedback lines, can be attached to the insulating wall elements 18.

Es ist auch denkbar, dass einzelne Antriebsteile am Ge­stell 14 befestigt oder gelagert sind. In vorteilhafter Weise sind aber sämtliche Antriebsteile an den Isolier­wandelementen 18 oder an an diesen Isolierwandelementen 18 befestigten Tragelementen angeordnet, so dass der ge­samte Federkraftantrieb 20 am Isoliertragrahmen 12′ mon­tiert werden kann, und dann diese Baueinheit auf dem Ge­stell 14 befestigt und eventuell mit den Isoliertragrah­men 12 verschraubt wird.It is also conceivable that individual drive parts are attached or mounted on the frame 14. In an advantageous manner, however, all drive parts are arranged on the insulating wall elements 18 or on supporting elements fastened to these insulating wall elements 18, so that the entire spring force drive 20 can be mounted on the insulating supporting frame 12 ', and then this structural unit is fixed on the frame 14 and possibly with the insulating supporting frame 12 is screwed.

Es ist auch möglich, dass Antriebsteile 24 verschiedenen Isoliertragrahmen 12, 12′ zugeordnet werden, so dass der Antrieb 20 auf alle drei Pole verteilt ist.It is also possible that drive parts 24 are assigned different insulating support frames 12, 12 ', so that the drive 20 is distributed over all three poles.

Es ist auch möglich, dass ein einziger Isoliertragrahmen die Vakuumschaltröhren 28 aller Pole aufnimmt und an die­sem einzigen Isoliertragrahmen ein Lagerungsteil oder mehrere Lagerungsteile für die Lagerung von Antriebstei­len vorgesehen sind.It is also possible for a single insulating support frame to hold the vacuum interrupters 28 of all poles, and one or more mounting parts for the storage of drive parts are provided on this single insulating support frame.
