Description

Schaltung für Hochfrequenzanlagen mit wenigstens drei Arbeitsstromkreisen vor der Antenne. Bei den Hochfrequenzanlagen mit mehreren Arbeitsstromkreisen stellen sich oft ganz unübersichtliche Spannungsverteilungsverhältnisse ein, die nicht nur durch die bekannten Elemente der Anlage, sondern auch durch unbekannte induktive und kapazitive Einflüsse der Umgebung bedingt sind. Dies führt unter Umständen zur Entstehung von Überspannungen an einzelnen Teilen der Anlage, auch dort, wo derartige Überspannungen bei gegebenen Werten der einzelnen Anlageelemente eigentlich nicht zu erwarten wären, und auch in dem Fall, daß ein Punkt der Anlage geerdet ist. Diese , Überspannungen führen leicht zu Durchschlägen zwischen verschiedenen Teilen der Anlage oder zwischen diesen und der Erde.Circuit for high-frequency systems with at least three working circuits in front of the antenna. In the case of high-frequency systems with several working circuits often very confusing tension distribution relationships arise, which not only by the known elements of the plant, but also by unknown inductive ones and capacitive influences of the environment are caused. This may lead to Creation of overvoltages on individual parts of the system, even where such Overvoltages for given values of the individual system elements are actually not would be expected, and also in the event that a point in the system is earthed. These , Surges easily lead to breakdowns between different parts of the Plant or between these and the earth.

Nach der Erfindung wird diese Durchschlagsgefahr dadurch bedeutend vermindert, da.ß man der Anlage auf einer längeren Strecke ein definitives Potential aufzwängt. Zu diesem Zweck werden bei allen galvanisch zusammenhängenden Teilen der Anlage die sämtlichen Abstimmorgane (Variometer, Kondensatoren u. dgl.) in die Seiten verlegt, die zu einem bestimmten Pol gehören, und die anderen Seiten frei von Abstimmorganen ausgeführt; außerdem werden diese letzteren Seiten zw eckmäßigerweise an ihrem einen oder beiden Endpunkten geerdet oder an einem Punkt bestimmten niedrigen Potentials angeschlossen.According to the invention, this risk of breakdown is significant diminished so that the system had a definite potential over a longer distance imposes. For this purpose, all galvanically connected parts of the system all tuning elements (variometer, capacitors, etc.) into the Pages that belong to a particular pole misplaced and the other pages free carried out by voting bodies; also these latter pages between corner-grounded at one or both endpoints or at one point connected to a certain low potential.

Die Abb. i zeigt ein Ausführungsbeispiel der Schaltung gemäß der Erfindung. m ist Generator, f Frequenzwandler, g seine Gleichstromwicklung, L Kopplungsspule, L1, C1, L2, C2, L3 und`C3 die Abstimmorgane von Arbeitsstromkreisen I, 11, 111.Fig. I shows an embodiment of the circuit according to the invention. m is generator, f frequency converter, g its direct current winding, L coupling coil, L1, C1, L2, C2, L3 and`C3 the tuning organs of working circuits I, 11, 111.

Alle diese Abstimmorgane sind nach der Erfindung in ein und derselben Zuleitung a von einem Pol der Maschine bis zum letzten Arbeitsstromkreis angeordnet, während die Zuleitung b von dem anderen Pol der Maschine bis zum zugehörigen Punkt des letzteren Kreises von den Abstimmorganen frei ist. Dieser Pol der Maschine ist in ei an Erde oder an das Maschinengehäuse angeschlossen.According to the invention, all these voting organs are in one and the same Lead a arranged from one pole of the machine to the last working circuit, while the lead b from the other pole of the machine to the associated point of the latter group is free from the voting bodies. This pole of the machine is in egg connected to earth or to the machine housing.

Auch das andere Ende der Zuleitung b ist zweckmäßigerweise geerdet (in e2).The other end of the supply line b is also expediently grounded (in e2).

Beim Ausführungsbeispiel nach Abb. z besteht die Anlage aus mehreren voneinander galvanisch getrennten, aber induktiv -gekoppelten Teilen. Auch in diesem Falle sind sämtliche Abstimmorgane L1, C1 bis L5 und C5 auf ein und dieselbe Seite a1, a2 der Anlage verlegt.In the embodiment according to Fig. Z, the system consists of several galvanically separated but inductively coupled parts. Also in this Trap are all voting organs L1, C1 to L5 and C5 on one and the same side a1, a2 of the system relocated.
