Bekanntlich üben Starkstromleitungen erhebliche Störungen auf benachbarte Schwachstromleitungen (Telephon-, Telegraphen- und auch Blockierungsleitungen) aus. Die Ursachen dieser Störungen beruhen zum großen Teil auf Induktionswirkung der von der Starkstromleitung ausgehenden magnetischen Felder. Führt die Starkstromleitung dreiphasigen Drehstrom, dann ist zwar während ίο des normalen Betriebes bei gleichmäßiger Belastung der drei Phasen der Starkstromleitung die Induktionswirkung verhältnismäßig gering, wenn die Schwachstromleitung nicht in der Nähe der drei Drehstromleitungen verläuft. Es treten aber auch in der weiter entfernten Schwachstromleitung erhebliche Störungen ein, wenn die Starkstromleitung infolge Störung, z. B. Erdschluß, eine unsymmetrische Stromverteilung aufweist.It is well known that power lines exert considerable interference on neighboring light power lines (Telephone, telegraph and also blocking lines). The reasons These disturbances are largely due to the induction effect of the magnetic emanating from the power line Fields. If the power line carries three-phase alternating current, then it is during ίο of normal operation with an even load on the three phases of the power line the induction effect is relatively low when the low-voltage line is not in the Near the three three-phase power lines. But it also occurs in the more distant Light current line causes significant disturbances if the high voltage line as a result of disturbance, z. B. earth fault, has an asymmetrical current distribution.
Besteht die Schwachstromleitung aus einem ao Hin- und einem Rückleiter, dann werden in der Hin- und Rückleitung durch die Induktionswirkung Spannungen mit entgegengesetzter Richtung induziert. Es kommen aber meistens trotzdem erhebliche Störströme zum Fließen, da die Spannungen nicht gleich groß sind und ein Differenzstrom sich ausbildet.If the low-voltage line consists of an ao forward and a return conductor, then in of the outward and return lines due to the induction effect, voltages with opposite voltages Direction induced. In most cases, however, considerable interference currents still flow because the voltages are not are of the same size and a differential current is formed.

Gegenstand der Erfindung ist eine Anordnung, mittels der sich derartige Differenzströme an Schwachstromleitungen mit einem Hin- und einem Rückleiter unterdrücken lassen. Erfindungsgemäß sind der Hin- und der -Rückleiter in etwa vertikaler Richtung übereinander angeordnet. Dadurch wird erreicht, daß die Induktionswirkung durch benachbarte Starkstromleitungen in bei-The invention relates to an arrangement by means of which such differential currents suppress on low-voltage lines with a forward and a return conductor. According to the invention, the outward and the return conductor arranged one above the other in an approximately vertical direction. Through this it is achieved that the induction effect through neighboring power lines in both

Beispielsweise zeigt Abb. ι der Zeichnung in ι die drei Leiter einer normal zur Zeichenebene verlaufenden Drehstromleitung, um die sich, namentlich bei unsymmetrischer Stromverteilung, magnetische Kraftlinien gemäß der Darstellung schließen. Diese magnetischen Kraftlinien, die in weiter Entfernung von der Starkstromleitung, wie dargestellt, in der Nähe des Erdbodens in vertikaler Richtung verlaufen, beeinflussen den Hin- und Rückleiter der Schwachstromleitung verschieden stark, wenn Hin- und Rückleiter, wie dies bisher üblich, in einer wagerechten Ebene nebeneinander angeordnet sind. Diese verschieden starke Beeinflussung wird.durch die Anordnung der Hin- und Rückleiter 2 und 3 der Schwachstromleitung in einer senkrechten Ebene behoben.For example, Fig. Ι of the drawing in ι shows the three heads normal to the plane of the drawing running three-phase current line, around which, especially in the case of asymmetrical power distribution, close magnetic lines of force as shown. These lines of magnetic force that are at a great distance from the power line, as shown, near the ground in the vertical direction run, affect the forward and return conductors of the low-voltage line differently strong when the outward and return ladder, as has been the case up to now, in a horizontal plane next to each other are arranged. This varying degree of influence is due to the arrangement the forward and return conductors 2 and 3 of the low-voltage line fixed in a vertical plane.
Man kann aber auch von der Starkstromseite aus die Induktionsstörungen in benachbarten Schwachstromleitungen vermindern, wenn man ferner erfindungsgemäß die Einzelleiter der Starkstromanlage in einer etwa senkrechten Ebene, ähnlich wie dies in der Zeichnung für die Schwachstromseite dargestellt ist, anordnet. Dies ist namentlich dann von Vorteil, wenn die Schwachstromleitung in der Nähe der Starkstromleitung verläuft. Es werden 'dadurch vor allem die durch den normalen Betriebsstrom der Starkstromleitung verursachten Störungen vermindert. But one can also see the induction disturbances in neighboring ones from the high voltage side Reduce low-current lines if, according to the invention, the individual conductors are also used the high voltage system in an approximately vertical plane, similar to this in the Drawing for the low-voltage side is shown, arranges. This is by name then advantageous if the low-voltage line is close to the high-voltage line runs. Thereby above all those caused by the normal operating current of the power line caused disturbances are reduced.
