Description
Es ist bekannt, bei Bündelungskörpern, die der Konzentration des durch eine Induktorspule erzeugten Hochfrequenzfeldes auf einen kleinen Raum dienen, die Induktorspule in einer Form anzuordnen, wie dies in Fig. i gezeigt ist. Untersucht man den Verlauf des Haupt- und Streufeldes bei einer derartigen Anordnung, so ergibt sich, daß das Streufeld eine verhältnismäßig große Ausbreitungsmöglichkeit besitzt. Unter Streufeld wird dabei dasjenige Feld verstanden, das nicht als Nutzfeld durch den Bündelungskörper hindurchtritt. Die Folge eines großen Streufeldes ist, daß neben der erforderlichen Spannungserhöhung des Generators der Rückschluß des Hauptfeldes über den Luftraum gedrosselt wird.It is known, in the case of bundling bodies, that the concentration of the through an inductor coil generated high-frequency field to serve in a small space that To arrange inductor coil in a shape as shown in Fig. I. Examined the course of the main field and the stray field with such an arrangement are obtained as follows that the stray field has a relatively large possibility of spreading. The stray field is understood to mean that field that does not pass through as a useful field the bundling body passes through. The consequence of a large stray field is that in addition to the necessary voltage increase of the generator, the conclusion of the main field is throttled through the airspace.
Man könnte den Feldrückschluß durch einen Massekern, der gemäß Fig. a angeordnet ist, verbessern. Man würde jedoch auch hierbei die Ausbildung des Streufeldes begünstigen.One could use the field inference by a ground core, which according to Fig. a is arranged to improve. However, the formation of the stray field would also be here favor.
Gemäß der Erfindung wird das Streufeld dadurch vernachlässigbar klein gemacht, daß die Windungen des Induktors in elektrischen Abschirml:arnmern verlegt sind. Als Werkstoff für die Abschirmkamtnern wird zweckmäßig elektrisch gut leitendes Material mit geringer Permeabilität, z. B, Kupfer, verwendet. Die Abschirmkammer .Q kann, wie in Fig. 3 gezeigt ist; in den Bündelungskörper eingelassen sein. Man kann aber auch eine getrennte Abschirmkammer anordnen und diese galvanisch mit dem Bündelungskörper verbinden. Um den Feldrückschluß zu begünstigen, kann man außerdem, wie im linken Teil der Fig. 3 angedeutet ist, einen Massekern M aus gut leitendem Material anbringen.According to the invention, the stray field is negligibly small as a result made that the windings of the inductor were laid in electrical shielding arms are. The material for the shielding chambers is expediently good electrically conductive Low permeability material, e.g. B, copper, is used. The shielding chamber .Q can, as shown in Figure 3; be embedded in the bundling body. Man but can also arrange a separate shielding chamber and galvanically connect it to the Connect bundling body. In order to favor the field inference, one can also, as indicated in the left part of FIG. 3, a ground core M made of a highly conductive Attach material.
