Abstract

En hellsk Induksjonsspole (40) for en transformatorfor- blndelse med høy frekvens og høy effekt, der spolen dannes ved utskjæring av delvise splralvlkllnger (44,46,48,50,52,54) festet til hverandre l brettellnjer (64,66,68,70,72), fra en metallplate. Forholdet mellom bredde og tykkelse er større enn ti. Etter utskjæring brettes emnet slik at de delvise splralvlkllnger delvis overligger hverandre for å danne en heliks der hver av hellksdelene er festet til hverandre ved hjelp av en brett l metallet. Hellksen er med fordel en sirkulær spole når den er ferdigstilt.A helical induction coil (40) for a high frequency and high power transformer joint, in which the coil is formed by cutting out partial splitter wheels (44,46,48,50,52,54) attached to each other in paddle rails (64,66,68 , 70.72), from a metal plate. The ratio of width to thickness is greater than ten. After cutting, the workpiece is folded so that the partial splashes are partially overlaid to form a helix in which each of the slab parts is attached to each other by means of a fold l metal. The helix is advantageously a circular coil when completed.
