Abstract (en)

A transformer,or reactor includes several sandwich- or pancake-windings connected electrically in parallel and/or in series, of which each has one or more turns arranged in a common plane. Each sandwich- or pancake-winding consists of a flat metal plate extending over the total winding surface and made of electrically conducting material with a slot of given width following the t contour. The turns (1-4) of each sandwich- or pancake- winding and the adjacent windings are respectively separated via heat-resista spacers (15) made of an electrically insulating material, and the inner (1) and outer (4) turn is equipped with an electrical contact device (5,6) for each sandwich- or pancake-winding.

Abstract (de)

Die Scheibenwicklungen zum Aufbau eines Transformators, eines Wandlers oder einer Drossel bestehen aus ebenen Metallplatten, in die ein der Windungskontur folgender Schlitz gegebener Breite eingebracht ist. Benachbarte Windungen (1 bis 4) werden durch Distanzelemente (15) separiert. Diese Distanzelemente können gleichzeitig dazu dienen, benachbarte Scheibenwicklungen auf Abstand zu halten. Die benachbarten Scheibenwicklungen können über Ösen (5, 6) an den Wicklungsenden miteinander elektrisch leitend verbunden werden, wobei durch Vorgabe des gleichen oder unterschiedlichen Wicklungssinns eine Parallel- oder Reihenschaltung der benachbarten Wicklungen zu erreichen ist. Die Scheibenwicklungen dienen zum Aufbau elektrischer Maschinen für mittlere bis große Leistungen. <IMAGE>
