Description
Hochfrequenzstromwandler Es ist bekannt, bei Hochfrequenzstrom. messungen, bei denen die Ablese- und die Meßstellen nicht die gleichen sind, Stromwandler zu verwenden. Ein weiterer Grund, der für die Verwendung von Stromwandlern spricht, ist der, daß die Raumkapazität der verwendeten Instrumente zu groß sein würde wenn sie direkt in die Leitung geschaltet sind.High Frequency Current Converter It is known to use high frequency current. measurements, where the reading and measuring points are not the same, current transformers too use. Another reason for using current transformers is is that the space capacity of the instruments used would be too great if they are connected directly to the line.
Die Raumkapazitäten der Stromwand erlassen sich dagegen wesentlich kleiner halten.The room capacities of the power wall, on the other hand, are largely eliminated keep it smaller.
Vorliegende Erfindung zeigt eine besonders raumsparende Anordnung eines Hochfrequenzstromwandlers, -die insbesondere bei Kurzwellengeräten vorteilhaft ist. Erfindungsgemäß wird die Sekundärwicklung des Hochfrequenzstromwandlers innerhalb des als Rohr ausgebildeten Primärleiters angeordnet. The present invention shows a particularly space-saving arrangement a high-frequency current converter, which is particularly advantageous for shortwave devices is. According to the invention, the secondary winding of the high-frequency current transformer is inside of the primary conductor designed as a tube.
In der Abbildung ist eine beispielsweise Ausführungsform des Erfindungsgedankens dargestellt. Der Primärleiter I (Rohr) besitzt einen großen Durchmesser, wie dies beispielsweise bei stromführenden Leitungen. die in Ultrakurzwellensendern verwendet werden, der Fall ist. Der Leiter I ist gemäß der Erfindung unterteilt und der eine Teil mit einem Ansatz A versehen. Der Stromwandler befindet sich im Innern des anderen Teiles, wobei gleichzeitig die Rohrwandung als Abschirmung dient. Beide Leiterteile sind durch ein Gewinde 0 miteinander verschraubt und damit leitend verbunden. Dieses Gewinde 0 befindet sich auf dem Zapfen und einer im anderen Leiterteil angebrachten Metallscheibe S. In the figure is an example embodiment of the inventive concept shown. The primary conductor I (pipe) has a large diameter like this for example with live lines. those used in ultra-short wave transmitters will be the case. The conductor I is divided according to the invention and the one Part with an approach A provided. The current transformer is inside the other Part, with the pipe wall serving as a shield at the same time. Both parts of the ladder are screwed together by a thread 0 and thus conductively connected. This Thread 0 is on the spigot and one in the other part of the ladder Metal disc S.
Hierbei ist zu beachten, daß die als Schirmung dienende Rohrwandung des einen Leiterteiles nicht mit der Rohnvandung des anderen Leiterteiles in Kontakt kommt, da sonst eine Kurzschlußwindung über Gewinde G, Ansatzteil A, Rohrleitung und Metallscheibe S hergestellt würde. Die durch die zusätzliche, infolge der Verschraubung entstehende Vergrößerung der Übergangswiderstände hervorgerufene Erwärmung kann durch angebrachte Kühlfahnen K abgeführt werden. Zur weiterenIt should be noted here that the pipe wall serving as shielding one part of the ladder is not in contact with the rough wall of the other part of the ladder comes, otherwise a short-circuit turn over thread G, attachment part A, pipeline and metal disk S would be produced. The by the additional, as a result of the screwing resulting increase in the contact resistance can cause heating be carried away by attached cooling vanes K. To further
