摘要:
The present invention relates to a DC transformer/reactor comprising a magnetic circuit, wherein the magnetic circuit comprises a magnetic core and at least one winding. The winding comprises at least one current-carrying conductor. Each winding comprises also an insulation system, which comprises on the one hand at least two semiconducting layers, wherein each layer constitutes substantially an equipotential surface, and on the other hand between them is arranged a solid insulation.
摘要:
An electric coil device such as a transformer or a choke has one or more windings (18, 20) around a core (12). In order to dispense with the conventional insulation means that have added much to the bulk of the coil device, each winding (18, 20) is formed by a conductor wire (24) on which at least two insulating tapes (26, 28) are wound one over the other and each with an overlap. The ratio of the width ( W ₁ or W ₂) of the overlap of one of the two insulating tapes (26, 28) to the width ( T ₁ or T ₂) of said one insulating tape differs from the ratio of the width ( W ₂ or W ₁) of the overlap of the other insulating tape to the width ( T ₂ or T ₁) of said other insulating tape. Preferably, a third insulating tape may be wound overlappingly over the two insulating tapes, with the ratio of the overlap of each tape to the tape width made progressively less from the inmost toward the outmost tape.

Gasgekühlte Wicklungsanordnung für Transformatoren
- mit um einen Kern angeordneten Wicklungen (7, 10), - mit wenigstens einem lsolationstorus (9), - in dessen Masse von einer benachbarten Wicklung (7) ausgehend dieser galvanisch verbundene Elektroden (12) zur elektrischen Feldstärkeentlastung zwischen Wicklung und Elektroden eingebettet sind.
Die mit den Elektroden (12) verbundene Wicklung (7) ist über die Wicklungshöhe in einzelne Wicklungsabschnitte (5, 6) aufgeteilt, und jeder der Abschnitte ist mit einer Elektrode (12) verbunden.
