Description
Hochfrequenzspule bzw. Transformator mit einem die Wicklung im wesentlichen umgebenden Hochfrequenzeisenkern Die Erfindung bezieht sich auf eine -1-lochfrequenzspule bzw. Transformator mit einem die Wicklung im wesentlichen umgebenden Hochfrequenzeisenkern, bei der bzw. dem die Wicklung aus mindestens drei in Reihe geschalteten und auf dem Kern nebeneinander angeordneten Teilwicklungen besteht. Es ist nahehegend und in den meisten Fällen am einfachsten und am günstigsten, die Wicklungsabschnitte in der gleichen Reihenfolge, in der sie auf dem Kern angeordnet sind, in Reihe zu schalten. Es -wurde jedoch gefunden, daß auch in dem Kern erhebliche Verluste auftreten können. Zur Verringerung dieser Verluste wird erfindungsgemäß vorgeschlagen, das Ende der einen äußeren Teilwicklung mit dem Anfang der anderen äußeren Teilwicklung und das Ende dieser Teilwicklung mit dem Anfang der mittleren Teilwicklung zu verbinden, während der Anfang der zuerst genannten äußeren und das Ende der mittleren Teilwicklung die Spulenzuführungen sind. Bei einer 'in dieser Weise gefertigten Spule wird zweckmäßig der mit der äußeren Teiltvicklung verbundene Zuführungsdraht mit dem Kern oder einem Gehäuse verbunden bzw. geerdet.High-frequency coil or transformer with a winding essentially surrounding high frequency iron core The invention relates to a -1-hole frequency coil or transformer with a high-frequency iron core essentially surrounding the winding, in which the winding consists of at least three connected in series and on the core consists of partial windings arranged next to one another. It is close and in most cases the easiest and cheapest, the winding sections in the same order in which they are arranged on the core, in series too switch. It has been found, however, that considerable losses also occur in the core can. To reduce these losses, it is proposed according to the invention that End of one outer partial winding with the beginning of the other outer partial winding and to connect the end of this partial winding with the beginning of the middle partial winding, during the beginning of the first mentioned outer and the end of the middle part winding the coil leads are. In the case of a coil manufactured in this way, it is expedient the lead wire connected to the outer partial winding with the core or a Housing connected or grounded.
Die Erfindung ist an Hand der Zeichnung näher :erläutert, in der eine Spule gemäß der Erfindung im Schnitt dargestellt ist.The invention is explained in more detail with reference to the drawing: in which one Coil according to the invention is shown in section.
Der Kern der dargestellten Spule besteht aus zwei scheibenförmigen Hälften i und in denen einander gegenüberliegende ringförmige Nuten vorgesehen sind. Die drei Spulenteihvicklungen 3, 4 und 5, die z. B. durch isolationsmaterial voneinander getrennt sind, liegen in dem auf diese Weise entstande-'@ien Raum, so daß sie ganz von Kernmaterial tungeben sind. Sie werden erfindungsgemäß in der Reihenfolge 3, 5, ¢ in Reihe geschaltet. Der mit der Teilwicklung 3 verbundene Stromzuführungsdraht wird mit dem Kern oder mit einem das Ganze umgebenden Gehäuse verbunden bzw. geerdet. Die dielektrischen Verluste im Kern sind in diesem Fall niedriger als bei Verwendung der üblichen Schaltung, da der Abstand zwischen der Teilwicklung, die während des Betriebes die höchste Wechselspannung hat, d. h. der Wicklung 4, und dem Kern größer ist. Es -wurde gefunden, daß auf diese Weise eine erhebliche Verringerung der Verluste im Kern erhalten wird.The core of the coil shown consists of two disc-shaped ones Halves i and in which opposing annular grooves are provided. The three coil winding 3, 4 and 5, the z. B. by insulation material from each other are separated, lie in the space created in this way, so that they are whole of nuclear material are tungeben. They are according to the invention in the order 3, 5, ¢ connected in series. The power supply wire connected to the partial winding 3 is connected or grounded to the core or to a housing surrounding the whole. The dielectric losses in the core are lower in this case than when it is used the usual circuit, since the distance between the partial winding that occurs during the Operation has the highest AC voltage, d. H. the winding 4, and the core larger is. It has been found that in this way there is a considerable reduction in losses is preserved in the core.
