Zusatz zum Patent 589Addition to patent 589
Patentiert im Deutschen Reiche vom 22. Juli 1930 ab Das Hauptpatent hat angefangen am 1. Januar 1930.Patented in the German Empire from July 22, 1930 onwards The main patent started on January 1, 1930.
Gemäß dem Hauptpatent 589 630 kann die einwandfreie Belieferung eines Verbrauchers auch im Kurzschlußfalle dadurch sicher- ■ gestellt werden, daß am Anfang und Ende einer zur Energieübertragung dienenden Doppelleitung je ein Transformator mit offener Hochspannungs wicklung vorgesehen- ist, deren Wicklungsanfänge an die eine und deren Wicklungsenden an die andere Leitung angeschlossen sind.According to the main patent 589 630, the flawless delivery of a consumer also in the event of a short circuit, ■ ensure that at the beginning and at the end a double line used for energy transmission, one transformer each with an open one High-voltage winding is provided, the winding beginnings of the one and whose winding ends are connected to the other line.
Erfindungsgemäß sind am Verbraucherende der Doppelleitung statt eines Transformators unmittelbar die Anfänge der Wicklungen des Verbrauchers selbst an die eine und die Enden an die andere Leitung angeschlossen. According to the invention are at the consumer end of the double line instead of a transformer directly the beginnings of the windings of the consumer itself are connected to one line and the ends to the other line.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es handelt sich hierbei um eine Eigenbedarfsanlage in einem elektrischen Kraftwerk. T ist ein Transformator, der von den Hochspannungssammelschienen HS gespeist wird und die Eigenbedarfssammelschienen NS I und NS II versorgt. An das eine Sammelschienensystem sind die Anfänge und an das andere Sammelschienensystem die Enden der offenen Sekundärwicklungen des. speisenden Transformators T angeschlossen. Die Verbraucher sind ebenfalls mit den Anfängen ihrer Wicklungen an das eine und mit den Enden an das andere Sammelschienensystem angeschlossen (z. B, der Motor M über den sechspoligen Schalter S). Ein Kurzschluß innerhalb des Motors M oder eines Stranges der Doppelleitung ist ungefährlich, da der auftretende Höchststrom durch die Spannung der nicht vom Kurzschluß, betroffenen Sekundärwicklungshälfte des Transformators T und die Impedanz des Motors M bestimmt ist.An exemplary embodiment of the invention is shown in the drawing. It is a self-consumption system in an electrical power plant. T is a transformer that is fed by the high-voltage busbars HS and supplies the auxiliary busbars NS I and NS II. The beginnings of the open secondary windings of the feeding transformer T are connected to one busbar system and the ends of the other busbar system. The consumers are also connected with the beginning of their windings to one busbar system and with the ends to the other busbar system (e.g. the motor M via the six-pole switch S). A short circuit within the motor M or a strand of the double line is not dangerous because the maximum current that occurs is determined by the voltage of the secondary winding half of the transformer T not affected by the short circuit and the impedance of the motor M.
Zweckmäßig wird an die Mittelpunkte der Sekundärwicklungen des Speisetransformators ein dreiphasiger Widerstand W angeschlossen, der geerdet wird. Hierdurch wird das Potential des ganzen Systems gegen Erde einwandfrei festgelegt, und außerdem kann man sowohl in die Erdverbindung als auch in Reihe oder parallel zu den einzelnen Widerständen Relais einschalten, die beim Eintreten eines Fehlers in der Anlage, z. B. eines Erdschlusses oder eines Kurzschlusses, ansprechen und entweder ein Signal oder eine Umschaltung derart veranlassen, daß der fehlerhafte Teil der Anlage außer Betrieb gesetzt wird. A three-phase resistor W , which is earthed, is expediently connected to the center points of the secondary windings of the supply transformer. In this way, the potential of the whole system to earth is properly established, and you can also switch on relays in the earth connection as well as in series or in parallel with the individual resistors. B. a ground fault or a short circuit, respond and either initiate a signal or a changeover in such a way that the faulty part of the system is put out of operation.

Der Erfindungsgegenstand eignet sich deshalb besonders für Eigenbedarfsanlagen, weil hier meist Doppelsammelschienensysteme vorhanden sind; denn wegen der kurzen Verbindungsleitungen würden bei Einfachleitungen verhältnismäßig große Kurzschlußströme entstehen können, die sehr große Schalter erfordern. The subject matter of the invention is therefore particularly suitable for systems for personal use because here mostly double busbar systems are available; because of the short connecting lines relatively large short-circuit currents would arise with single lines, which require very large switches.
