Description

  

  Wicklung für     Hochspannungsmaschlinen.       Bei Wicklungen, die in Maschinen für  hohe Spannungen eingebracht werden, müssen  die Ei     inzelleiter    aus elektrostatischen Gründen  mit stark abgerundeten Ecken ausgeführt  werden. Dadurch entstehen Zwickel, in denen  sehr hohe Beanspruchungen auftreten. Mai)  könnte diese Beanspruchungen dadurch herab  setzen,     dass    matt die Zwickel mit einer iso  lierenden Masse ausfüllt. Das Ausfüllen bietet  aber technische Schwierigkeiten, denn die  Zwickel müssen vollkommen homogen aus  gefüllt werdet), wenn der durch das Aus  füllen beabsichtigte Zweck erreicht werden  soll.

   Ein einfacheres Mittel, den hoben Be  anspruchungen in den Zwickeln zu begegnen,  wird durch die Erfindung dadurch gegeben,       dass    die Hülsen der Einzelleiter mit einem  leitenden Belag, zum Beispiel Metallfolie,  umgeben werden, und     dass    die Innenseite  der diese Leiter gemeinsam umgebenden Hülse    ebenfalls mit einem solchen Belag versehen  wird.  



  In der Zeichnung ist ein Ausführungs  beispiel der Erfindung veranschaulicht. Sie  zeigt den Querschnitt durch die Seite einer  Wicklung, die in eine Nut einer Hochspan  nungsmaschine eingelegt werdet) soll. Die  Einzelleiter t sind zunächst mit Isolations  material i umgeben. Auf dieses Isolations  material ist ausserdem noch ein leitender Be  lag<B>b</B> aus Metallfolie aufgetragen. Ferner  umgibt die einzelnen Leiter noch eine     ge-          ineinsame    Hülse h. Diese Hülse ist innen  ebenfalls mit einem leitenden Belag<B>g</B> ver  sehen.

   Durch die     Bei#übrung    der leitenden  Beläge<B>b</B> Lind<B>g</B> befinden sich die Begren  zungsflächen der Zwickel z auf gleichem  Potential, so     dass    ein elektrostatisches Feld,  das Glimmfeuer hervorrufen könnte, in den  Zwickeln gar nicht erst entstehen kann.



  Winding for high voltage machines. In the case of windings that are installed in machines for high voltages, the egg inzelliter must be designed with rounded corners for electrostatic reasons. This creates gussets in which very high loads occur. May) could reduce these stresses by the fact that matt fills the gusset with an insulating compound. However, filling out offers technical difficulties, because the gussets must be filled completely homogeneously if the purpose intended by filling out is to be achieved.

   A simpler means of counteracting the high demands in the gusset is provided by the invention in that the sleeves of the individual conductors are surrounded by a conductive coating, for example metal foil, and that the inside of the sleeve that jointly surrounds this conductor is also enclosed such a covering is provided.



  In the drawing, an embodiment example of the invention is illustrated. It shows the cross section through the side of a winding that is to be inserted into a slot of a high-voltage machine). The individual conductors t are initially surrounded with insulation material i. A conductive coating made of metal foil is also applied to this insulation material. The individual conductors are also surrounded by a common sleeve h. This sleeve is also provided with a conductive coating <B> g </B> on the inside.

   Due to the addition of the conductive coatings <B> b </B> and <B> g </B>, the boundary surfaces of the gusset z are at the same potential, so that an electrostatic field that could cause glowing fire in the Twisting cannot arise in the first place.
