Description

  

  Kondensator klemme.    Zum     Schutz    der     Windungsisolation    elek  trischer Maschinen und Apparate, insbeson  dere elektrischer Hochspannungstransforma  toren, gegen Überbeanspruchung durch Über=  spanneng steiler Wellenform insbesondere  atmosphärischen Ursprungs werden an den  Einführungsklemmen vielfach sogenannte       Schutzkondensatoren    abgezweigt.  



  Die Einrichtung wird wesentlich ver  billigt und vereinfacht, wenn die Einführungs  klemme, die     alt    und für sich schon eine  gewisse, allerdings sehr geringe Kapazität  darstellt, mit dem Schutzkondensator zu  einem einzigen Apparat 'vereinigt wird.  



  Das Kennzeichen der Erfindung besteht  in der Vereinigung eines Schutzkondensators  von     eitler    wesentlich grösseren Kapazität als  der Eigenkapazität einer Einführungsklemme,  mit der Einführungsklemme zu einer bau  lichen Einheit, wobei in bereits bekannter  Art, zum Zwecke der Erzielung einer ent  sprechenden Potentialverteilung sowohl in der  Längs- wie auch in der Querrichtung, lei  tende Beläge mit Unterteilungen des Kon-         densators    in leitende Verbindung gebracht  werden können.  



  In der Zeichnung ist ein Ausführungsbei  spiel der     Kondensatorenklemme    dargestellt.  Es bedeutet     l    den Stromleiter, der mit  den     Isolierröhren        ii,        i2,        ia    überzogen ist. Die  Isolierröhren sind mit den leitenden Bele  gungen     a,i   <I>a2, a3</I> belegt, welche mit den  Armaturen d leitend verbunden sind.  



  Die Isolierröhren     il,        i2,        i3    mit ihren     11Ie-          tallbelägen        a1,        ä2,        a3    und dem     Konduktor   <I>l</I>  ergeben drei in Serie geschaltete Kondensa  toren von relativ kleiner Kapazität.  



  Um die Kapazität -zu vermehren, sind  zwischen den Belägen     a2-as,        ai-az    und  zwischen     1.=ai    je vier Gruppen Teilkonden  satoren k eingeschaltet, die unter sich in Serie  liegen. Diese     Kondensatorgruppen,    welche im       Zwischenraum    zwischen den Isolierröhren     ii,          i2,        is    und den Hüllen<I>h</I> untergebracht sind,  sind mithin jeweils zu den durch die     Isolier-          röhren        ii,        i2,

          is    mit den Enden ihrer Beläge       ai,        a2,        a3    und dem Konduktor     l    gebildeten  Kondensatoren parallel geschaltet.      Die überwiegende Kapazität dieser Teil  kondensatoren     @    erzwingt ein gleichmässiges  Potentialgefälle sowohl in der Richtung längs  den Hüllen als     auch    quer dazu in den Isolier  röhren     i1,        i2,        is.     



  Die Anwendung der Erfindung ist an  keine besondere     Kondensatorenart    gebunden  und ist unabhängig von dem verwendeten       Dielektrikurn.  



  Capacitor terminal. To protect the winding insulation of electrical machines and apparatus, in particular electrical high-voltage transformers, against overstressing caused by overvoltage steep waveform, especially of atmospheric origin, so-called protective capacitors are often branched off at the entry terminals.



  The device is much cheaper and simplified ver if the introduction terminal, which is old and in itself a certain, but very low capacity, is combined with the protective capacitor to a single apparatus'.



  The distinguishing feature of the invention is the combination of a protective capacitor of much greater capacity than the self-capacitance of an insertion terminal, with the insertion terminal to form a structural unit, in a known manner, for the purpose of achieving a corresponding potential distribution both in the longitudinal as In the transverse direction, conductive coverings can also be brought into conductive connection with subdivisions of the capacitor.



  In the drawing, a Ausführungsbei is shown playing the capacitor terminal. It means l the current conductor, which is covered with the insulating tubes ii, i2, ia. The insulating tubes are covered with the conductive assignments a, i <I> a2, a3 </I>, which are conductively connected to the fittings d.



  The insulating tubes il, i2, i3 with their metal coatings a1, ä2, a3 and the conductor <I> l </I> result in three series-connected capacitors of relatively small capacitance.



  In order to increase the capacity, four groups of partial capacitors k are switched on between the pads a2-as, ai-az and between 1. = ai and are connected in series. These capacitor groups, which are housed in the space between the insulating tubes ii, i2, is and the sheaths <I> h </I>, are therefore each to the through the insulating tubes ii, i2,

          is connected in parallel with the ends of their linings ai, a2, a3 and the conductor l formed capacitors. The predominant capacity of these partial capacitors @ enforces a uniform potential gradient both in the direction along the sheaths and across them in the insulating tubes i1, i2, is.



  The application of the invention is not tied to any particular type of capacitor and is independent of the dielectric used.
