Description

Stromwandler Die in dem Hauptpatent 510 593 behandelte Ausführung, wonach die Primärwickhingsenden des Stromwandlers in zwei voneinander getrennten Hochspannungsisolatoren nach außen geführt werden, kommt in der Praxis wenig vor.Current transformer The version dealt with in the main patent 510 593 , according to which the primary winding ends of the current transformer are led to the outside in two separate high-voltage insulators, is rarely used in practice.

Meistens werden die beiden Enden der Primärwicklung in einem Isolator hochgeführt. Das in dem 'Hauptpatent beschriebene Schaltungsprinzip läßt sich auch für derartige Stromwandler durchführen, wie z. B. beiliegende Zeichnung zeigt.Most often the two ends of the primary winding are in an insulator brought up. The circuit principle described in the main patent can also be used perform for such current transformers, such. B. accompanying drawing shows.

Fig. i zeigt einen Stromwandler, in welchem die beiden Wicklungsenden der Primärspule w' in einem Isolator i nach den Klemmen p1 und p_ geführt sind. Auf die eine dieser beiden Klemmen, z. B. p=, wird ein Klemmenstück (Fig. 2), bestehend aus zwei Metallstücken p,', p.., aufgesetzt, die durch eine lösbare Brücke an. miteinander leitend verbunden sind.Fig. I shows a current transformer in which the two winding ends of the primary coil w ' are guided in an insulator i after the terminals p1 and p_. On one of these two terminals, e.g. B. p =, a clamp piece (Fig. 2), consisting of two metal pieces p, ', p .., is placed, which is connected to by a detachable bridge. are conductively connected to each other.

p2' ist mit der Klemme p; durch die isolierende Trägerplatte t hindurch elektrisch leitend verbunden.p2 'is connected to the terminal p; through the insulating support plate t electrically connected.

Im normalen Betrieb fließt der Netzstrom von p1 über W, p2, p_', m, p j zum Verbraucher. Beim Prüfen des Stromwandlers wird der Kontrollwandler h zwischen p,' und p;; geschaltet und die Verbindung p".', p., über in, geöffnet.In normal operation, the mains current flows from p1 via W, p2, p_ ', m, pj to the consumer. When checking the current transformer, the control transformer h is set between p, 'and p ;; switched and the connection p ". ', p., via in, opened.

Ein derartiges Klemmstück läßt sich nicht nur bei neu zum Einbau kommenden Stromwandlern, sondern insbesondere auch bei bereits vorhandenen Stromwandlern anbringen.Such a clamping piece can be used not only for new ones to be installed Attach current transformers, but also, in particular, to existing current transformers.

Bei neuen Wandlern kann selbstverständlich auch p. und p=' aus einem Stück hergestellt sein.With new converters, p. and p = 'from one Piece to be made.
