No. 3,605,013 and DE-PS 21 30 047. In the latter document, an arrangement of an optical fiber winding within the housing of a metal-encapsulated, pressurized gas-insulated switchgear is specified. Aufgabe der Erfindung ist es, eine besonders vorteilhafte und kostengünstige Ausführung für eine Stromwandleranordnung der eingangs genannten Art anzugeben.The object of the invention is to specify a particularly advantageous and cost-effective design for a current transformer arrangement of the type mentioned at the outset. Diese Aufgabe wird durch die im Kennzeichen des Patent-5 anspruchs 1 enthaltenen Merkmale gelöst.This object is achieved by the features contained in the characterizing part of Patent 5 claim 1. In der Zeichnung sind Ausführungsbeispiele der Erfin-dung schematisch im Schnitt dargestellt.In the drawing, exemplary embodiments of the invention are shown schematically in section. Fig. 1 zeigt einen in einem Hochspannungsschalter eingebauten Stromwandler,Fig. 1 shows a current transformer installed in a high-voltage switch, Fig. 2 und Fig. 3 zeigen einen in einer metallgekapselten Hochspannungsschaltanlage eingebauten Stromwandler. 15 Der in Fig. 1 dargestellte Hochspannungsschalter besteht aus einer hohlen Porzellansäule 14 und einem zentralen Kurbelgehäuse 6, an dem beidseitig waagrechte Schaltkammern 7 angeschraubt sind. Es ist nur die rechte Hälfte des Schalters gezeichnet. Die Lichtleiterwicklung 1 des Stromwandlers ist 20 in einem Giessharzring 2 eingegossen. Der Giessharzring ist an der Innenseite des Schaltergehäuses in einer Ringnut zwischen dem Kurbelgehäuse 6 und der Schaltkammer 7 eingeklemmt. Innerhalb des hohlen Stützisolators 14 befindet sich ein Lichtleiterpaar 13, das die Verbindung zwischen Erdpo-2S tential und Giessharzring 2 herstellt.2 and 3 show a current transformer installed in a metal-enclosed high-voltage switchgear. 15 The high-voltage switch shown in FIG. 1 consists of a hollow porcelain column 14 and a central crankcase 6, to which horizontal switching chambers 7 are screwed on both sides. Only the right half of the switch is drawn. The light conductor winding 1 of the current transformer is cast in a casting resin ring 20 . The cast resin ring is clamped on the inside of the switch housing in an annular groove between the crankcase 6 and the switching chamber 7 . Inside the hollow support insulator 14 there is a pair of light guides 13 which establish the connection between earth potential and casting resin ring 2 . In Fig. 2 ist ein Abschnitt aus einer metallgekapselten Hochspannungsschaltanlage dargestellt. Die Schaltanlage besitzt den Innenleiter 17 und das Gehäuse 9,10. Der Innenleiter ist durch einen Konusstützer 11, der aussen in einen 30 Flansch zwischen den Gehäuseteilen 9,10 eingeklemmt ist, abgestützt. In der Flanschverbindung ist neben dem Aussenrand des Konusstützers ein Giessharzring 3 eingeklemmt, der in seinem unteren Teil die eingegossene Lichtleiterwicklung 1 aufnimmt.
