Description

Hochfrequenzapparat . . . Nach dem Hauptpatent wird bei einem Hochfrequenzapparat die Verbreitung von Störschwingungen, die durch die Funkeustreckenwirkung des Wagnerschen Hammers hervorgerufen werden, über die Netzleitungen dadurch verhindert, daß die Wege vom Hammer und seinem Gegenkontakt zum Netz elektrisch gleichwertig gemacht werden, indem entweder in die vom Netz direkt zum Wagnerschen Hammer führende Leitung eine Drosselspule, die der Wicklung des Unterbrechers praktisch gleichwertig ist, eingeschaltet wird, oder die Induktionsspule in zwei gleiche Teile geteilt und je zur Hälfte in die beiden Stromzweige gelegt wird.High frequency apparatus. . . According to the main patent, a high-frequency apparatus the spread of interfering vibrations caused by the radio link effect of Wagner Hammers are caused on the power lines by preventing the Routes from the hammer and its counter-contact to the network made electrically equivalent either in the line leading from the network directly to Wagner's hammer a choke coil practically equivalent to the winding of the breaker, is switched on, or the induction coil is divided into two equal parts and each is placed halfway in the two branches.

Eine besonders günstige störungsbeseitigende Wirkung erhält man hierbei dann, wenn man gemäß vorliegender Erfindung die Induktionsspule, wie es bei derartigen Spulen an sich schon vorgeschlagen ist, in eine axial aneinandergereihter Flachspulen auflöst. Dadurch wird die sonst vorhandene kapazitive Wirkung der einzelnen Lagen der Induktionsspule aufeinander in bekannter Weise beseitigt. Es können infolgedessen die Störschwingungen nicht kapazitiv auf das Netz übertragen werden, so daß hierdurch die Symmetrieschaltung des Hauptpatents in ihrer störungsbeseitigenden Wirkung unterstützt wird.A particularly favorable interference-eliminating effect is obtained here then, if one according to the present invention the induction coil, as it is with such Coils has already been proposed in an axially juxtaposed flat coils dissolves. This eliminates the otherwise existing capacitive effect of the individual layers the induction coil eliminated in a known manner. It can as a result the interfering vibrations are not capacitively transferred to the network, so that this supports the symmetry circuit of the main patent in its interference-eliminating effect will.

Die Abbildung zeigt beispielsweise die Erfindung in Anwendung auf die in zwei Hälften cl, c2 geteilte und je zur Hälfte in die beiden Stromzweige a1, a2 gelegte Induktionsspule.For example, the figure shows the invention in use the one divided into two halves c1, c2 and half each into the two branches a1, a2 laid induction coil.
