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.
