Description

Querlochstromwandler . ' Die Erfindung bezieht sich auf die besonders zweckmäßige Anordnung und Ausbildung eines Ouerlochstromwartdlers. Erfindungsgemäß ist der Stromwandler am Kopf eines Stützisolators angeordnet, dessen Isoliermaterial auch die Isolation des Ouerlochstroinwandlers bildet. Der Stützisolator ist in der für Freileitungsstützisolatoren bekannten Art und Weise ausgebildet. Die Erfindung erweist sich insbesondere als zweckmäßig, wenn für Innenraumschaltanlagen:öllose Wandler verwendet werden. Durch 'die Anordnung des Querlochstromwandlers auf einexn'Stützisolator ist die Isolierung des Hochspannungsstroinw-andlers. gegenüber der Umgebung sowie seine Befestigung in .einfachster Weise gelöst.Cross-hole current transformer. 'The invention relates to the particularly appropriate arrangement and design of an Ouerlochstromwartdler. According to the invention the current transformer is arranged on the head of a post insulator, its insulating material also forms the isolation of the Ouerlochstroinwandler. The post insulator is in the designed for overhead line support insulators known manner. The invention proves to be particularly useful when for indoor switchgear: oil-free Transducers are used. By arranging the cross-hole current transformer on a support insulator is the insulation of the high voltage current converter. towards the environment as well its fastening solved in the simplest way.

Die Zeichnung veranschaulicht die neue Anordnung an einem Beispiel, wobei Abb. i und 2 zwei aufeinander senkrecht- stehende Längsschnitte eines Ouerlochstromwandlers darstellen. i ist der Isolationsmantel. des Stützisolators. Es können in bekannter Weise mehrere solcher ineinandergeschobener Mäntel vorhanden sein. Der Kopf des Stützisolators ist ,nun für die Aufnahme des Querlochstromwandlers ausgebildet. Zu diesem Zweck weist er ein die äußeren Mantelflächen des Kopfes verbindendes Querloch 2 auf: Durch dieses Querloch ist die Primärwicklung 3 des Wandlers hindurchgefädelt. Die Sekundärwicklung 4 und das Tränsformatoreisen 5 befinden sich, wie dargestellt, im Innern des Isolatorkopfes. Wie aus der Darstellung der Abb. i hervorgeht, kann dabei die Sekundärwicklung in normaler 'Weise als Maschinenwicklung hergestellt werden. Sie kann durch die Öffnungen d im Innern des Isolatorkopfes in die in Abb. i dargestellte Lage gebracht werden: Zum Schluß wird dann der ebenfalls maschinell fertiggestellte Spiraleisenkern 5 in den Kopf eingefädelt.The drawing illustrates the new arrangement using an example, where Fig. i and 2 are two mutually perpendicular longitudinal sections of an Ouerlochstromwandler represent. i is the insulation jacket. of the post insulator. It can be known in Way, there may be several such nested coats. The head of the Post insulator is now designed to accommodate the transverse hole current transformer. For this purpose, it has a transverse hole connecting the outer jacket surfaces of the head 2 up: The primary winding 3 of the converter is threaded through this transverse hole. The secondary winding 4 and the Tränsformatoreisen 5 are, as shown, inside the insulator head. As can be seen from the illustration in Fig. I, while the secondary winding is produced in the normal way as a machine winding will. It can be inserted through the openings d in the interior of the insulator head into the position shown in Fig. i position shown: Finally, the is then also machine finished spiral iron core 5 threaded into the head.

Gegenüber den bekannten Querlochstromwandlern, bei denen der Stromwandler mit einem Durchführungsinsolator derart vereinigt ist, daß die Isolation des Durchführungsisolators auch die Isolation des Stromwandlers bildet, bietet die Anordnung nach der Erfindung vor allem für Innenraumschaltanlagen wesentliche Vorteile, da man den Stromwandler ebenso wie einen Stützisolator leicht an beliebiger Stelle anbringen kann, während der bekannte Ouerlochstromwandler nur für Durchführungsanordnungen bestimmt ist.Compared to the known cross-hole current transformers, in which the current transformer is combined with a bushing insulator in such a way that the insulation of the bushing insulator also forms the insulation of the current transformer, offers the arrangement according to the invention Main advantages, especially for indoor switchgear, since you can use the current transformer as well as a post insulator can easily be attached at any point while the well-known Ouerlochstromwandler is only intended for bushing arrangements.

PATENTANSPRÜCHE: i. Querlochstromwandler, dadurch gekennzeichnet, daß der Stromwandler in den Kopf eines Stützisolators derart eingebaut ist, daß *an dem Kopf des Stützisolators ein die äußeren Mantelflächen verbindendes Ouerloch vorgesehen ist, so daß das Isoliermaterial des Kopfes des Stützisolators auch die Isolation des Querlochstromwandlers bildet. Anordnung _ nach Anspruch i, dadurch gekennzeichnet, daß durch das Ouerloch die Primärwicklung des Stromwandlers hindurchgeht, während die Sekundärwicklung und das Wandlereisen sich im Innern des Isolatorkopfes befinden. Zur Abgrenzung des Anmeldungsgegenstandes vom Stand der Technik ist im Erteilungsverfahren folgende Druckschrift in Betracht gezogen worden: Abhandlung: »Stromwandler« in Verbandsmitteilungen des Dresdner Bezirksvereins der Deutschen Ingenieure, Jhg. 1927, S. 201 ff.PATENT CLAIMS: i. Cross-hole current transformer, characterized in that the current transformer is built into the head of a post insulator in such a way that an Ouerloch connecting the outer jacket surfaces is provided on the head of the post insulator, so that the insulating material of the head of the post insulator also forms the insulation of the cross-hole current transformer. Arrangement according to Claim i, characterized in that the primary winding of the current transformer passes through the Ouerloch, while the secondary winding and the transformer iron are located inside the insulator head. To distinguish the subject of the application from the state of the art, the following publication was considered in the granting procedure: Treatise: "Current transformer" in association communications of the Dresden District Association of German Engineers, Jhg. 1927, p. 201 ff.
