PATENTAMT.PATENT OFFICE.
Bekanntlich bildet bei den modernen Hochspannungsanlagen, bei denen Spannungen von ioo ooo Volt und darüber angewandt werden, jeder Isolator eine Quelle von Störungen, die den einwandfreien Betrieb unter Umständen empfindlich beeinträchtigen können. Diejenige Anlage muß daher als die betriebssicherste angesehen werden, die mit der geringsten Anzahl von Isolatoren auskommt. Nach vorliegender Erfindung wird die Zahl der erforderlichen Isolatoren einer Anlage dadurch vermindert, daß man die Sammelschienen in der Zentrale oder Unterstation nicht wie bisher unmittelbar auf die Stützisolatoren setzt oder an Hängeisolatoren aufhängt, sondern daß man sie an einem Tragdraht aufhängt, der seinerseits nur an seinen beiden Enden isoliert zu werden braucht. Die Art der Aufhängung ist für die Oberleitung von Bahnen sowie im Brückenbau als sogenannte Kettenaufhängung bekannt, dient aber hier einem durchaus neuen und eigenartigen Zweck, der Aufhängung der Sammelschienen in Hochspannungsanlagen, wodurch die genannten erheblichen Vorteile gegenüber den bisher üblichen Befestigungsarten der Sammelschienen erzielt werden.It is known that in modern high-voltage systems, where voltages of ioo ooo volts and above are applied, any isolator being a source of interference that can seriously impair proper operation under certain circumstances. The one The plant must therefore be regarded as the most reliable, the one with the lowest number makes do with isolators. According to the present invention, the number of required Insulators of a system are reduced by not having the busbars in the control center or substation as before directly on the post insulators or hanging on suspension insulators, but that one hangs them on a suspension wire, which in turn only at both ends needs to be isolated. The type of suspension is for the catenary of railways as well as in bridge building known as so-called chain suspension, but serves one here a completely new and peculiar purpose, the suspension of the busbars in high-voltage systems, whereby the aforementioned considerable advantages over the previously common types of fastening of the busbars be achieved.
Um die Längssteifigkeit der Sammelschienen zu gewährleisten, gibt man ihnen einen Querschnitt von entsprechender Form, z. B. von L-, U-, T-, H-, Z-, S-, Kreuz- oder Ringform.To ensure the longitudinal stiffness of the busbars, they are given a cross-section of appropriate form, e.g. B. of L, U, T, H, Z, S, cross or ring shape.
Die Lage in der Querrichtung wird durch die senkrecht von den Schienen abzweigenden Leitungen festgelegt, denen man ebenfalls ein die Versteifung gewährleistendes Profil gibt.The position in the transverse direction is determined by the lines branching off vertically from the rails set, which are also given a stiffening-ensuring profile.
In der Zeichnung ist eine Sammelschienenanlage nach der Erfindung, bestehend aus den drei Sammelschienen einer Drehstromstation, in den drei Projektionen dargestellt. Die Tragdrähte t sind beiderseits an einer Reihe von Hängeisolatorenh befestigt; an den Tragdrähten hängen die Sammelschienen s von rohrförmigem Querschnitt, und an diese sind die ebenfalls rohrförmigen Abzweigleitungen a angeschlossen, deren Steifigkeit beispielsweise verhindert, daß bei Erschütterungen die Sammelschienen s zusammenschlagen.In the drawing, a busbar system according to the invention, consisting of the three busbars of a three-phase current station, is shown in three projections. The support wires t are attached on both sides to a series of suspension insulators h ; the busbars s of tubular cross-section hang from the carrying wires, and the branch lines a, which are also tubular, are connected to them, the rigidity of which prevents the busbars s from collapsing in the event of vibrations.
