Die nachfolgend beschriebene Erfindung bezieht sich auf Wechselstromwandler und bezweckt eine Sicherung gegen etwaigen Stromübergang zwischen den primären und secundären Wickelungen durch Zwischenschaltung eines die Energie übermittelnden, an Erde gelegten Leiters. Die Anordnung ist besonders in solchen Fällen von Werth, wo Gefahr gegen Blitzschläge vorliegt oder wo hohe Spannungen in Anwendung kommen.The invention described below relates to AC converters and aims a safeguard against any current transfer between the primary and secondary Windings through the interposition of an energy-transmitting, connected to earth Head. The arrangement is of particular value in cases where there is danger against Lightning strikes are present or where high voltages are used.
Die Erfindung besteht im wesentlichen in einem doppelten Stromwandler mit gesonderter Wickelung auf jedem Kern in Verbindung mit' Kupferbä'ndern, welche die beiden Stromwandler verbinden und so angeordnet sind, dafs sie mit ihrem einen Theile die Secundärwickelung des ersten Umwandlers, mit ihrem anderen Theile die Primärwickelung des zweiten Umwandlers bilden. In diesen Kupferbändern treten erhebliche Spannungsunterschiede nicht auf, sie können daher unmittelbar mit Erde verbunden werden. Sie bieten auf diese Weise im Falle mangelhafter Isolation einer Spule eine Erdverbindung für dieselbe dar und vermeiden die Möglichkeit eines unmittelbaren Stromüberganges zwischen den Spulen.The invention consists essentially in a double current transformer with a separate one Winding on each core in connection with 'copper tapes' which the two current transformers and are so arranged that one part of them forms the secondary winding of the first transducer, with their other part form the primary winding of the second transducer. In these copper bands significant voltage differences do not occur, so they can be directly connected to earth get connected. They offer this way in the event of poor insulation of a coil represent an earth connection for the same and avoid the possibility of an immediate Current transfer between the coils.
Die Fig. 1, 2 und 3 veranschaulichen den Gegenstand der Erfindung.Figs. 1, 2 and 3 illustrate the subject matter of the invention.
Fig. ι zeigt eine obere Ansicht, Fig. 2 eine Seitenansicht und Fig. 3 eine Ausführungsform der Kupferbänder mit Ansatzstück für die Erdverbindung. Fig. 1 shows a top view, Fig. 2 shows a side view and Fig. 3 shows an embodiment the copper strips with extension piece for the earth connection.
A B sind die Kerne des doppelten Stromwandlers, wie üblich aus untertheiltem Eisen hergestellt. P ist die Primärspule, die ihren Strom aus irgend einer geeigneten Stromquelle erhält. C C sind die in geeigneter Weise zwischen den Spulen angeordneten Kupferbänder oder Platten, die sich über beide Spulen erstrecken. S auf Kern B sind die secundären Spulen. Diese können je nach Bedarf parallel oder in Reihe geschaltet sein. AB are the cores of the double current transformer, made as usual from divided iron. P is the primary coil, which gets its power from any suitable power source. CC are the copper tapes or plates suitably placed between the coils and extending across both coils. S on core B are the secondary coils. These can be connected in parallel or in series as required.
Von den Kupferbändern ist eine Erdverbindung E abgezweigt, so dafs beim Eintreten eines Isolationsfehlers einer Spule ein unmittelbarer Stromübergang zur Erde stattfindet. An earth connection E is branched off from the copper strips, so that if an insulation fault occurs in a coil, there is a direct current transfer to earth.
