Description

  

  Isolator.    Die     Befesti-un-    von Isolatoren auf ihrer  n<B>,</B>  Unterlage ohne     Kittung    wird bisher mittels  Ringen, Klauen, Laschen und dergleichen aus  geführt. Die Befestig     ng    durch Ringe     er-          ZDU   <B>C</B>  fordert genau     geseliliffene    Isolatoren und sehr  grosse Sorgfalt beim Anziehen der Schrauben;  <B>e</B>  trotzdem lassen sieh einseitige     Belastungen     der sehr empfindlichen     keramisehen    Isolatoren  nicht vermeiden. Dadurch werden sowohl bei  der Montage als auch im Betriebe sehr oft  die Isolatoren zerstört.

   Das Schleifen der       holatorfüsse    ist zudem eine wesentliche Ver  teuerung. Besser ist in dieser Beziehung die  Befestigung durch mehrere Klauen. Sie er  fordert     jedoeli    in der Unterlage fest ver  schraubte Stehbolzen, welche, um ein     Aus-          Negen    zu vermeiden, durch     Lasehen    oder  Ringe untereinander verbunden werden müs  sen. Die     Lasehen    wie auch die Ringe müssen  sehr genau ausgeführt werden, sollen sie ihre  Aufgabe zweckmässig erfüllen. Sie oft auch  ausgeführte Abstützung der Klauen an der  Unterlage erfordert einen grösseren Raum.

    Bei Verwendung dieser     Befestigningsart    au  n kn       Hoehspannungsisolatoren    treten an den vielen  Kanten und Spitzen sehr oft Glimmentladun  gen auf; -um dies zu vermeiden,     muss    über die  ganze Anordnung noch eine abgerundete,  glatte Abschirmung gelegt werden.  



  Diese Nachteile lassen sieh durch die vor  liegende Erfindung vermeiden, die darin be  steht,     dass    zur Befestigung des Isolators     auf     einer Unterlage Ringsegmente angeordnet  sind, die mittels Schrauben den     Isolatorfuss            #1j11    die Unterlage pressen Lind durch eine  verstellbare     Bride    zusammengehalten werden.  



       Iii        Fig.   <B>1</B> ist eine beispielsweise Ausfüh  rung des Erfindungsgegenstandes im Schnitt  dargestellt;     Fig.    2 zeigt einen Schnitt nach  der Linie     A-A    der     Fig.   <B>1.</B>  



  <I>In</I>  <B>1</B> sind die Ringsegmente, welche durch  Schrauben 2 an den Fuss<B>3</B> des Isolators 4     ge-          presst    und gegen die Unterlage<B>5</B> gezogen  werden. Um eine     Biegungsbeanspruehung    der  Sehrauben 2 zu vermeiden, werden die     Ring-          se,-mente   <B>1</B> durch eine mittels der Schraube<B>6</B>  verstellbare     Bride   <B>7</B> zusammengehalten. Die       Bride   <B>7</B> wird durch Schrauben<B>8</B> au wenig  stens zwei     Ringse-Menten   <B>1</B> befestigt, wodurch  ein Abgleiten der     Bride   <B>7</B> verhindert wird.

    Die     Bride    kann auch durch Stifte an den  Ringsegmenten befestigt werden.    Eine andere Möglichkeit der Befestigung  der     Bride   <B>7</B> zeigt die Variante gemäss     Fig.   <B>3.</B>  Sie besteht darin, die Ringsegmente<B>1</B> mit  einer Rille<B>9</B> zu versehen, womit das<B>Ab-</B>  gleiten der     Bride   <B>7</B> ebenfalls verhindert wird.  Auf diese einfache Art lassen sieh, ohne     Kit-          Jung,        ungesehliffene    Isolatoren auf ihrer  Unterlage, z. B. weiteren Isolatoren, befesti  gen, wobei eine gleichmässige mechanische     Be-          ansprueh-Ling    des Isolators erreicht wird.

    Durch     dieglatte    Oberfläche der     Rin"segmente     erhält auch das elektrische Feld an der Be  festigungsstelle des Isolators eine günstige  Form, so     dass    keine besonderen Massnahmen  mehr notwendig sind.



  Insulator. The fastening of insulators on their n <B>, </B> base without cement has hitherto been carried out by means of rings, claws, tabs and the like. Fastening with rings ZDU <B> C </B> requires precisely sanded insulators and great care when tightening the screws; <B> e </B> nevertheless, one-sided loading of the very sensitive ceramic insulators cannot be avoided. As a result, the isolators are very often destroyed both during assembly and in operation.

   Grinding the holator feet is also a significant increase in price. In this respect, it is better to use multiple claws. However, it requires stud bolts that are firmly screwed into the base, which must be connected to one another by loops or rings in order to avoid discomfort. The lasehas as well as the rings must be executed very precisely if they are to perform their task properly. They often also performed support of the claws on the base requires a larger space.

    When using this type of fastening au n kn high voltage insulators very often glow discharges occur on the many edges and tips; -To avoid this, a rounded, smooth shield must be placed over the entire arrangement.



  These disadvantages can be avoided by the present invention, which consists in the fact that ring segments are arranged to fasten the insulator on a base, which press the base by means of screws and are held together by an adjustable clamp.



       III Fig. 1 is an exemplary embodiment of the subject matter of the invention is shown in section; FIG. 2 shows a section along the line A-A of FIG. 1



  <I> In </I> <B> 1 </B> are the ring segments which are pressed by screws 2 onto the foot <B> 3 </B> of the insulator 4 and against the base <B> 5 < / B> be pulled. In order to avoid bending stresses on the visual hoods 2, the rings, elements <B> 1 </B> are held together by a clamp <B> 7 </B> which can be adjusted by means of the screw <B> 6 </B>. The bracket <B> 7 </B> is fastened by screws <B> 8 </B> to at least two rings <B> 1 </B>, which causes the bracket <B> 7 </ B to slide off > is prevented.

    The clamp can also be attached to the ring segments with pins. Another possibility for fastening the clamp <B> 7 </B> is shown in the variant according to FIG. 3. It consists in the ring segments <B> 1 </B> having a groove <B> 9 </B>, which also prevents the Bride <B> 7 </B> from sliding down. In this simple way you can leave unshielded insulators on your base without Kit-Jung, e.g. B. other insulators, fasten conditions, whereby a uniform mechanical loading of the insulator is achieved.

    Due to the smooth surface of the ring segments, the electrical field at the fastening point of the insulator is also given a favorable shape, so that no special measures are necessary.
