Description

Es ist bekannt, die Leistung von drahtlosen Sendern dadurch zu beeinflussen, daß man Spulen mit Eisenkernen in den Hochfrequenzkreis einschaltet, die zusätzlich mit Gleichstrom magnetisiert werden, wodurch infolge Sättigungserscheinung des Eisens der Selbstinduktionskoeffizient sowie der Dämpfungswiderstand der Spule verändert werden und somit die Leistung des Hochfrequenzsenders beeinflußt werden kann. . Man kann aber auch bekanntlich eine besondere Spule mit Eisenkern vermeiden, wenn es sich um Hochfrequenzanlagen handelt, bei denen die Frequenzen mittels Transformatoren hochtransformiert werden, indem man den Hochfrequertransformator selbst mit einer zusätzlichen Gleichstrommagnetisierung versieht.It is known to affect the performance of wireless transmitters by Coils with iron cores in the high-frequency circuit turns on, which additionally with direct current are magnetized, whereby the self-induction coefficient due to the saturation phenomenon of the iron as well as the damping resistance of the coil can be changed and thus the performance of the high-frequency transmitter can be influenced. . But you can also use a special coil with Avoid iron core when it comes to high frequency systems where the frequencies can be stepped up by means of transformers by using the high frequency transformer even provided with an additional direct current magnetization.

Die Erfindung· hat eine Einrichtung zum Gegenstand, durch welche eine besonders vorteilhafte Beeinflussung der Hochfrequenzan- ao lage erreicht ist. Das Wesen der Erfindung besteht darin, daß die Kerne der Magnetisierungsspule und der Hochfrequenzspule gelrennt sind und der beeinflußte Hochfrequenztransformator oder die beeinflußte Hochfrequenzspule zwischen die Pole des die Magnetisierungsspule tragenden Kerns- angeordnet sind. Im Gegensatz zu bekannten Anordnun-The subject of the invention is a device by means of which a particularly advantageous Influencing the high-frequency anao is achieved. The essence of the invention is that the cores of the magnetizing coil and the high frequency coil are disconnected and the affected high frequency transformer or affected high frequency coil arranged between the poles of the core carrying the magnetizing coil are. In contrast to known arrangements

gen, bei denen die Hochfrequenzspule mit der Gleichstrommagnetisierungsspule vereinigt ist, bilden daher nach der Erfindung der Hochfrequenztranformator bzw. die Hochfrequenzspule einerseits und die Magnetisierungsspule andererseits getrennte Einrichtungen, wobei aber trotzdem der Kraftfluß der Magnetisierungsspule auf den Hochfrequenztransformator bzw. auf die Hochfrequenzspule zur Einwirkung gebracht wird. Durch die neue Anordnung ist namentlich der Vorteil erzielt, daß. für die Magnetisierungsspule einerseits und für den Hochfrequenztransformator bzw. für die Hochfrequenzspule andererseits verschiedenes, für den jeweiligen Zweck besonders günstiges Kernmaterial verwendet werden kann. In Abb. ι und 2 der Zeichnung ist die neue Einrichtung in zwei verschiedenen Ausführungsformen dargestellt.genes in which the high frequency coil is combined with the direct current magnetizing coil, therefore, according to the invention, form the high-frequency transformer or the high-frequency coil on the one hand and the magnetizing coil on the other hand separate devices, wherein but still the power flow of the magnetizing coil on the high-frequency transformer or is brought into action on the high-frequency coil. With the new arrangement the advantage is achieved that. for the magnetizing coil on the one hand and for the high-frequency transformer or for the high-frequency coil, on the other hand, different things, Core material which is particularly favorable for the respective purpose can be used. In Fig. Ι and 2 of the drawing, the new device is in two different embodiments shown.

Bei der Ausführungsform nach Abb. 1 ist der beeinflußte Hochfrequenztransformator bzw. die beeinflußte Hochfrequenzspule in Form des bekannten Toroids i zwischen die Pole eines starken Elektromagneten tn gelegt. Der Kraftfluß des Elektromagneten m fließt beiderseits durch das Toroid und magnetisiert dieses Toroid. Der die Wicklung η tragende Kern des Elektromagneten tn kann massiv oder aus starken Eisenblechen hergestellt sein. Um die sich im geringen Maße bildenden Ströme doppelter Frequenz aufzunehmen, ist es vorteilhaft, die Hochfrequenzwicklung in zwei parallelen Teilen It1, A2 auszuführen.In the embodiment according to Fig. 1, the affected high-frequency transformer or the affected high-frequency coil in the form of the known toroid i is placed between the poles of a strong electromagnet tn . The flux of force of the electromagnet m flows through the toroid on both sides and magnetizes this toroid. The core of the electromagnet tn carrying the winding η can be solid or made of strong iron sheets. In order to absorb the double-frequency currents which are formed to a small extent, it is advantageous to design the high-frequency winding in two parallel parts It 1 , A 2 .

Der Hauptvorteil der Erfindung besteht darin, daß die durch Gleichstrom zu beeinflussende Hochfrequenzspule bzw. der Transformator ohne Rücksichtnahme auf den Gleichstromkreis gebaut werden kann, wobei die zu beeinflussende Gleichstrommagnetisierung von einem besonderen Teil ausgeht, der beliebig angeordnet und aus massivem Eisen, das außerdem auch noch Kurzschlußwicklungen tragen kann, ausgeführt werden kann. In Abb. 2 ist ein derartiger Transformator dargestellt, bei dem der Kern des Elektromagneten Ot1, zwischen dessen Polen der Transformator ^1 angeordnet ist, außer der Erregerwicklung OT1 zwei Kurzschlußwicklungen A1, k2 trägt. Die als Wicklung dienenden Leiter sind in diesem Fall durch den Kern des Transformators tL hindurchgeführt.The main advantage of the invention is that the high-frequency coil to be influenced by direct current or the transformer can be built without considering the direct current circuit, the direct current magnetization to be influenced starting from a special part, which is arbitrarily arranged and made of solid iron, which also has Can carry short-circuit windings, can be executed. In Fig. 2 such a transformer is shown in which the core of the electromagnet Ot 1 , between whose poles the transformer ^ 1 is arranged, apart from the excitation winding OT 1, has two short-circuit windings A 1 , k 2 . In this case, the conductors h « serving as the winding are passed through the core of the transformer t L.

Durch die Trennung der beiden obenerwähnten Teile — Hochfrequenzeinrichtung und Gleichstrommagnetisierungsspule — ist der weitere Vorteil erzielt, daß die Hochfrequenzeinrichtung· mit einem geringsten Maß an Eisen ausgeführt werden kann, wodurch die Eisenverluste verringert werden.By separating the two parts mentioned above - high frequency device and DC magnetizing coil - the further advantage is achieved that the high-frequency device can be carried out with the least amount of iron, thereby reducing iron losses.
