Description

  

      Randabdichtung    an Trennwänden in ölgefüllten Gefässen für elektrische Apparate.    In ölgefüllten Gefässen für elektrische  Apparate, insbesondere Widerstände, Drossel  spulen, Transformatoren, Induktionsregler,  bringt man häufig     Trennwände    oder Ab  schlussböden an, die beispielsweise zur Tren  nung und Führung von kaltem und warmem  Öl dienen und nicht starr mit dem Gefäss  verbunden sind. Der Rand solcher Wände soll  möglichst dicht abschliessen und eine Ver  mischung der zu beiden     Seiten    desselben vor  handenen Ölmengen verhindern.  



  Erfindungsgemäss wird die Abdichtung  des Randes der Trennwände gegen die Ge  fässwandung durch einen elastischen oder  elastisch     angepressten    Stoff bewirkt, der  längs des Randes der Trennwand befestigt  ist.  



  In der Zeichnung sind fünf Ausführungs  beispiele für     die    Erfindung dargestellt. Darin  bedeutet a die Wandung eines     Transformator-          Ölkastens    und b die Trennwand     bezw.    den Ab  schlussboden.  



  Die Abdichtung erfolgt gemäss     Fig.    1  nach Art einer Stopfbüchse, indem über den  an der Platte b     befestigten        Führungsring    c    der     Pressring    d geschoben wird, der mittelst  keilförmiger Flächen die elastische Dich  tungseinlage e gegen die Gefässwand a presst,  wenn die     Schrauben    f angezogen werden.  



  Gemäss     Fig.    2 werden     äls    Dichtungs  mittel steife Bürsten oder Gewebestreifen g  verwendet.  



       Fig.    3 zeigt eine     Dichtung,    bei der der  Rand der Platte b mit einer Nut versehen  ist; in dieser ist ein besonderer Dichtungs  träger h verschiebbar, auf dessen Aussen  rand eine elastische Einlage i befestigt ist.  Der Dichtungsträger<I>i</I> ist     mittelst    Stiften<I>k</I>  in der     Platte    b geführt und wird durch kleine       Schraubenfedern        l    nach aussen gepresst. Der  bewegliche Teil der Dichtung kann durch eine  Tuchkappe m abgedeckt werden.  



  Die Dichtung nach den     Fig.    4 und 5  besteht aus mit einer Tuchlage m überspann  ten Blattfedern n     bezw.    o verschiedener Form.  Dabei darf die einzelne Blattfeder in Rich  tung des Plattenrandes nicht allzu breit sein,  damit das Tuch überall gleichmässig am     Ka-          sten        a    anliegt.



      Edge sealing on partition walls in oil-filled vessels for electrical apparatus. In oil-filled vessels for electrical equipment, especially resistors, chokes, transformers, induction regulators, partitions or trays are often attached, which are used, for example, to separate and guide cold and warm oil and are not rigidly connected to the vessel. The edge of such walls should be as tight as possible and prevent the same amount of oil from mixing on both sides of the wall.



  According to the invention, the sealing of the edge of the partition walls against the vessel wall is effected by an elastic or elastically pressed material which is fastened along the edge of the partition.



  In the drawing, five execution examples are shown for the invention. Therein a means the wall of a transformer oil box and b the partition or respectively. the final floor.



  The sealing takes place according to Fig. 1 in the manner of a stuffing box, in that the press ring d is pushed over the guide ring c attached to the plate b, which presses the elastic sealing insert e against the vessel wall a by means of wedge-shaped surfaces when the screws f are tightened.



  According to FIG. 2, stiff brushes or fabric strips are used as sealing medium.



       Fig. 3 shows a seal in which the edge of the plate b is provided with a groove; in this a special seal carrier h is displaceable, on the outer edge of which an elastic insert i is attached. The seal carrier <I> i </I> is guided by pins <I> k </I> in the plate b and is pressed outwards by small coil springs l. The moving part of the seal can be covered by a cloth cap m.



  The seal according to FIGS. 4 and 5 consists of a layer of cloth m overstretched leaf springs n respectively. o different shape. The individual leaf spring must not be too wide in the direction of the edge of the plate so that the cloth rests evenly on the box a everywhere.
