Description
Einrichtung zur Messung hochfrequenter Ströme Es ist bekannt, die Ablenkung eines Elektronenstrahles in einem magnetischen oder elektrischen Feld zu benutzen, um den zeitlichen Verlauf von schnell veränderlichen Spannungen oder Strömen zu verfolgen. Auf diesem Prinzip beruht z. B. die Anwendung der Braunschen Röhre zur oszillograpliischen Untersuchung der Kurvenform von veränderlichen Strömen (Hochfrequenz- und Wechselströmen). Sie bat als wichtigstes Organ. einen axial in einer Glasröhre verlaufenden, Elektronenstrahl, dessen Endpunkt sich auf dem Fluoreszenzschirm durch Leuchten markiert.Device for measuring high-frequency currents It is known that Deflection of an electron beam in a magnetic or electric field to use the time course of rapidly changing voltages or To track streams. Based on this principle z. B. the application of the Braunschen Tube for the oscillographic investigation of the curve shape of variable currents (High frequency and alternating currents). She asked as the main organ. one axially in electron beam running through a glass tube, the end point of which is on the fluorescent screen marked by lights.
Erfindungsgemäß wird die Brgunsche Röhre dadurch zur Messung elektrischer Hochfrequenzströme benutzt, daß der zu messende Strom einen innerhalb der Braunschen Röhre angeordneten bügelförmigen Leiter durchströmt, der den Elektronenstrahl umschließt. Die Vorteile des neuen Meßinstrumentes bestehen, abgesehen von der Möglichkeit, den üblichen Instrumenten unzugängliche Gebiete (Amperemeter für Hochfrequenz) der genauen Messung zu erschließen, vor allem darin, daß der Elektronenstrahl trägheitslos ist und keine unzuverlässigen Lagerungen eines trägen Zeigerorgans vorhanden sind, so daß die Einstellung des Ausschlages sofort erfolgt, kein Haken des Zeigers möglich ist und das Meßinstrument gefahrlos stark überlastet werden kann. Es besteht ferner weitgehende Prop,ortionalität zwischen Ablenkung des Elektronenstrahles und den zu messenden Größen. Der Leuchtschirm der Braunschen Röhre ist in an sich bekannter Weise mit Teilungen versehen, um die Meßgrößen unmittelbar ablesen zu können.According to the invention, the Brgun's tube is thereby used for measuring electrical High-frequency currents used that the current to be measured is within the Braunsche Tube arranged bow-shaped conductor flows through, which surrounds the electron beam. The advantages of the new measuring instrument are, apart from the possibility of Areas inaccessible to the usual instruments (high frequency ammeter) of the to tap into accurate measurement, especially in the fact that the electron beam is inertia and there are no unreliable bearings of an inert pointer organ, so that the deflection is set immediately, the pointer cannot be hooked and the measuring instrument can be safely overloaded. It also exists extensive prop, ortionalität between deflection of the electron beam and the sizes to be measured. The luminescent screen of the Braun tube is known in and of itself Way provided with graduations in order to be able to read off the measured variables directly.
In der Zeichnung ist eine Ausführungsform des Meßinstrumentes nach der Erfindung beispielsweise dargestellt.In the drawing is an embodiment of the measuring instrument according to the invention shown for example.
In der Zeichnung bedeutet G: die Kathode, von der ein Elektronenstrahl S ausgeht, der auf dem Leuchtschirm einen Fluoreszenzfleck B hervorruft. Der zu messende Hochfrequenzstr om fließt durch den Leiter L, der im Innern der Röhre zu einem Bügel B ausgestaltet ist, durch den der ElektronenstrahliS hindurchgeht. Diese Anordnung bietet den besonderen Vorteil, daß das Instrument geringe Kapazität und Induktivität und geringsten Widerstand hat. Auf diese Weise kann man eine Empfindlichkeit des Meßinstrumentes von etwa 5 Amp. für die ganze Ableseskala erreichen.In the drawing, G means: the cathode from which an electron beam S goes out, which causes a fluorescent spot B on the luminescent screen. The to The measuring high-frequency current flows through the conductor L, which is inside the tube a bracket B is designed through which the electron beam passes. These Arrangement has the particular advantage that the instrument has a low capacity and Has inductance and lowest resistance. That way you can have a sensitivity of the measuring instrument of about 5 amps for the entire reading scale.
