Abstract

Beim erfindungsgemässen Stromwandler sind die verwendeten Bauteile neuartig angeordnet. Die Primärwicklung (7) ist in einem Abstand, der zur Einführung einer Hochspannungsisolation (10) vorhanden ist, um die Sekundärwicklung (8) mit gestrecktem Kern (9) angeordnet. Sekundärwicklung (8) und Kern (9) befinden sich in einem geerdeten, elektrisch leitenden Rohr (12), in welchem die Ableitungen der Sekundärwicklung zur Erde geführt sind. Mit diesem Aufbau wird die nach dem Stand der Technik notwendige gegenseitige Umschlingung von Kern und Wicklungen, welche für manche Anwendung ungüstig und fertigungstechnisch aufwendig ist, vermieden.
