Description

  

      Streckentrenner    im Fahrdraht elektrischer Bahnen.    Gegenstand der vorliegenden Erfindung  ist ein     Streckentrenner    im Fahrdraht elek  trischer Bahnen, d. h. ein im Fahrdraht elek  trischer Bahnen eingebauter Apparat, welcher  die elektrische Unterteilung einer mit Fahr  draht ausgerüsteten     Geleisestrecke    ermöglicht.  



  Der Erfindungsgegenstand weist zwei über  einander angeordnete, vorzugsweise     stabför-          mige    Isolationen auf, wovon die obere auf  Druck, die untere auf Zug beansprucht wird.  



  Die Zeichnung stellt ein Ausführungsbei  spiel des Erfindungsgegenstandes durch     Fig.    1  im Aufriss, durch     Fig.    2 im Grundriss dar.  



       a    und b sind die voneinander zu trennen  den Fahrdrähte. Ihre Enden sowie die Schleif  bügel     c,    d sind in bekannter Weise durch  Drahtklemmen h an Waagebalken e angeschlos  sen, und zwar direkt oder isoliert, je nachdem  diese Schleifbügel stromführend oder strom  los sein müssen. Zwischen die untern Enden  dieser Waagebalken ist die bei     Streckentren-          nern    übliche, auf Zug beanspruchte Isolation  feingesetzt, die aus einem oder mehreren,         zweckmässigerweise        stabförmigen    Isolatoren  bestehen kann.  



  Während nun bei den bis jetzt gebräuch  lichen     Streckentrennern    ähnlicher Art die  obern Enden der beiden Waagebalken e rück  wärts an den Fahrdrähten     a        bezw.   <I>b</I> veran  kert waren, ist beim dargestellten     Strecken-          trenner    diese Verankerung durch eine zwi  schen die obern Enden der Waagebalken e  eingesetzte Isolation     g    ersetzt, die auf Druck  beansprucht wird und ebenfalls aus einem  oder mehreren, vorzugsweise     stabförmigen    Iso  latoren bestehen kann, und zweckmässiger  weise in der vertikalen     Achsialebene    der Iso  lation f liegt.  



  Durch den Wegfall der Rückverankerungen  kann die Länge der ganzen eingebauten     Strek-          kentrennung    von bisher ca. 12 Meter und  mehr auf kaum     1/io    dieser Länge reduziert  werden, was namentlich in Bahnhöfen mit  dichten     Geleiseanlagen    einen wesentlichen Vor  teil bedeutet. Durch Wegfallen der Rückver  ankerungen kann ausserdem erreicht werden,  dass der Zug im Fahrdraht über die ganze      Trennstrecke hinweg der normale der ganzen  Leitungsanlage bleibt, was bei der früheren  Anordnung nicht der Fall war und stets als  nachteilig für das Befahren der Trennstelle  mit Höchstgeschwindigkeit empfunden wurde.

    Bei     Streckentrennern        rnit        Rückverankerungen     wird nämlich der Leitungszug innerhalb der  Angriffspunkte der     Rückverankerungskabel     am Fahrdraht um denjenigen Teil des Fahr  drahtzuges reduziert, welcher zwangsläufig  durch diese Kabel aufgenommen wird.  



  Es empfiehlt sich,     wenigstens    die eine der  Isolationen<I>f, g</I> so auszubilden, dass ihre Länge  regelbar ist, um die     Fahrdrahtklemmen    h an  den Waagebalken e genau in die Richtung der  anschliessenden Fahrdrähte einstellen zu kön  nen.



      Section separator in the contact wire of electric railways. The present invention is a line separator in the contact wire elec tric railways, d. H. a device built into the contact wire of electric railways, which enables the electrical subdivision of a track section equipped with contact wire.



  The subject matter of the invention has two, preferably rod-shaped, isolations arranged one above the other, of which the upper one is subjected to pressure and the lower to tension.



  The drawing shows an exemplary embodiment of the subject matter of the invention through FIG. 1 in elevation, through FIG. 2 in plan.



       a and b are the contact wires to be separated from each other. Their ends and the grinding bow c, d are ruled out in a known manner by wire clamps h to the balance beam e, directly or isolated, depending on whether this grinding bow must be live or dead. Between the lower ends of this balance beam, the usual tensile insulation, which is common in section isolators, is finely set, which can consist of one or more, expediently rod-shaped insulators.



  While now with the up to now common line separators of a similar type, the upper ends of the two balance beams e backwards on the contact wires a respectively. <I> b </I> were anchored, this anchoring is replaced in the illustrated section separator by an insulation g inserted between the upper ends of the balance beam e, which is subjected to pressure and also consists of one or more, preferably rod-shaped iso can exist and conveniently located in the vertical axial plane of the insulation f.



  By eliminating the back anchors, the length of the entire built-in line separation can be reduced from around 12 meters and more to barely 1/10 of this length, which is a significant advantage, especially in stations with dense track systems. By eliminating the back anchors, it can also be achieved that the train in the contact wire remains the normal of the entire line system over the entire separation distance, which was not the case with the previous arrangement and was always felt to be disadvantageous for driving on the separation point at maximum speed.

    In the case of section insulators with back anchors, the line run within the points of application of the back anchoring cables on the contact wire is reduced by that part of the contact wire that is inevitably taken up by these cables.



  It is advisable to design at least one of the insulations <I> f, g </I> in such a way that its length can be regulated in order to be able to adjust the contact wire clamps h on the balance beam e precisely in the direction of the connecting contact wires.
