Description

  

      Überstromrelais    für Ölschalter grosser Stromstärken.    Bei der Anordnung von Hochspannungs  schaltern mit direkter Auslösung ist man  genötigt, den     Überstrommagneten,    der mei  stens Hochspannung führt, mit den Auslöse  teilen durch eine Isolationsstange von ent  sprechender Isolation zu verbinden. Diese  Anordnung führt häufig zu sehr     unlieb-          sr        men    Störungen im Betrieb, da das zu ver  wendende Isolationsmaterial leicht hygro  skopisch wirkt oder die beim Eintreten von  Kurzschluss auftretenden mechanischen Stösse  nicht mit genügender Sicherheit aushält.

   Um  diese Fehler zu vermeiden, kann man bei  Anordnungen, bei denen man ausgegossene  Durchführungen verwendet, deren     Mittelteil          aus        11letall    besteht, den     Überstrommagneten          an    diesem stets geerdeten Teil anbringen, so  dass sämtliche Teile der     Überstrommagneten     mit geerdet sind. Die sich daraus ergebende  Anordnung ist in der beispielsweisen Zeich  nung dargestellt. Die Durchführung     a    be  sitzt eine geerdete Fassung b, um die das  Eisen c des Ü     berstrommagnetes    d herum-    gelegt ist.

   Die Betätigungsstange e nach den       Auslöseteilen    f kann aus leitendem     Material     bestehen.  



  Erreicht der Überstrom eine bestimmte  Grösse, so wird der die Durchführung     a     durchsetzende Leiterteil den ihn umgebenden  Teil c so stark magnetisieren, dass er den  Anker d anzieht und durch die an letzterem  angebrachte Nase e die Auslösung bei f  bewirkt.



      Overcurrent relay for oil switches with high currents. When arranging high-voltage switches with direct tripping, you need to connect the overcurrent magnet, which usually carries high voltage, with the release parts through an insulation rod of appropriate insulation. This arrangement often leads to very unpleasant malfunctions in operation, since the insulation material to be used has a slightly hygroscopic effect or the mechanical shocks that occur when a short circuit occurs cannot withstand the mechanical impacts with sufficient reliability.

   In order to avoid these errors, one can attach the overcurrent magnet to this always earthed part in arrangements in which one uses poured bushings, the middle part of which is made of 11letall, so that all parts of the overcurrent magnets are also earthed. The resulting arrangement is shown in the exemplary drawing. The bushing a has a grounded socket b around which the iron c of the overcurrent magnet d is placed.

   The actuating rod e after the release parts f can be made of conductive material.



  If the overcurrent reaches a certain size, the conductor part passing through the bushing a will magnetize the part c surrounding it so strongly that it attracts the armature d and triggers the triggering at f through the lug e attached to the latter.
