Description

DEUTSCHESGERMAN

Gegenstand der Erfindung ist ein kapazitiver Spannungswandler mit Anschlußmöglichkeit für hochfrequente Signalübertragung. Erfindungsgemäß sind die zum Anschluß für die Hochfrequenzsignalübertragung vorgesehenen Klemmen im Stromkreis des kapazitiven Spannungsteilers mittels eines mit der Frequenz mehr als linear wachsenden Widerstandes, z. B. eines die Arbeitsfrequenz gegebenenfalls einschließlich der erwünschten Oberwellen des kapazitiven Spannungswandlers durchlassenden Tief- oder Bandpasses oder eines auf die Arbeitsfrequenz des kapazitiven Spannungswandlers abgestimmten Reihenresonanzkreises, überbrückt.The invention relates to a capacitive voltage converter with connection option for high-frequency signal transmission. Are according to the invention the terminals provided for connection for high-frequency signal transmission in the circuit of the capacitive voltage divider by means of a resistor that increases more than linearly with the frequency, z. B. one of the working frequency, possibly including the desired harmonics of the capacitive Voltage converter passing low or band pass or one to the working frequency of the capacitive Voltage transformer matched series resonance circuit, bridged.

Infolge dieser erfindungsgemäßen Ausbildung kann der kapazitive Spannungsteiler des Wandlers gleichzeitig als Koppelkondensator für den Anschluß der hochfrequenten Signalübertragung benutzt werden, ohne daß der kapazitive Spannungswandler einerseits durch das Anschließen der hochfrequenten Signalübertragung hinsichtlich seiner Meßgenauigkeit unzulässig beeinflußt wird und andererseits einen unerwünscht großen Anteil der Hochfrequenzenergie aufnimmt. Man kann den genannten Widerstand entweder von außen zugänglich mit den Klemmen verbinden oder gegen äußere Eingriffe unzugänglich an die Klemmen anschließen. Im letzten Fall ist die Möglichkeit gegeben, den kapazitiven Spannungswandler gegen unbefugte, die Meßgenauigkeit beeinträchtigende Eingriffe zu schützen, indem alle Teile, bei denen solche Beeinflussungsmöglichkeit besteht, plombiert werden können; es bleiben dann nur die Klemmen für den Anschluß der Hochfrequenzsignalübertragung von außen frei zugänglich.As a result of this design according to the invention, the capacitive voltage divider of the converter can simultaneously be used as a coupling capacitor for the connection of the high-frequency signal transmission, without the capacitive voltage converter on the one hand by connecting the high-frequency signal transmission is influenced inadmissibly with regard to its measurement accuracy and on the other hand an undesirable absorbs a large proportion of the radio frequency energy. One can use the said resistance either Connect to the terminals accessible from the outside or inaccessible to external interference connect the terminals. In the latter case there is the option of using the capacitive voltage converter to protect against unauthorized tampering with the measurement accuracy by removing all parts where such influencing possibility exists, can be sealed; then only the terminals remain for the connection of the high-frequency signal transmission freely accessible from the outside.

Zur Erläuterung der Erfindung ist in der Zeichnung in schematicher Darstellung ein kapazitiver Spannungswandler wiedergegeben, der aus dem kapazitiven Spannungsteiler Sp mitden aus Kondensatorelementen aufgebauten Teilkapazitäten C1 und C2 und einem an die Teilkapazität C2 angeschlossenen Spannungszweig besteht, welcher sich in bekannter Weise aus den Drosseln Dr1, Dr9 und dem Zwischenwandler W zusammensetzt. An den Klemmen A1 und A2 im Stromkreis des kapazitiven Spannungsteilers Sp kann die Ankoppking der zur Hochfrequenzsignalübertragung dienenden BauelementeHF erfolgen. Die Klemmen.^ und A2 sind durch den mit der Frequenz mehr als linear wachsenden Widerstand Wif überbrückt. Dieser Widerstand kann z. B. aus einem die Arbeitsfrequenz gegebenenfalls einschließlich der erwünschten Oberwellen des kapazitiven Spannungswandlers durchlassenden Tief- oder Bandpaß oder einem auf die Arbeitsfrequenz des kapazitiven Spannungswandlers abgestimmten Reihenresonanzkreis bestehen. Sofern man diesen Widerstand gegen äußere Eingriffe unzu-Kapazitiver SpannungswandlerTo explain the invention, a capacitive voltage converter is shown in the drawing in a schematic representation, which consists of the capacitive voltage divider Sp with the partial capacitances C 1 and C 2 made up of capacitor elements and a voltage branch connected to the partial capacitance C 2 , which is made up in a known manner from the Chokes Dr 1 , Dr 9 and the intermediate converter W composed. The coupling of the components HF used for high-frequency signal transmission can take place at terminals A 1 and A 2 in the circuit of the capacitive voltage divider Sp. The terminals. ^ And A 2 are bridged by the resistance Wif , which increases more than linearly with the frequency. This resistance can e.g. B. consist of a low-pass or band-pass filter that allows the working frequency to pass through, including the desired harmonics of the capacitive voltage converter, or a series resonant circuit tuned to the working frequency of the capacitive voltage converter. Unless you have this resistance to external interference, in-too-capacitive voltage converters

Der Widerstand Wif ist so bemessen, daß die Hochfrequenzsignalübertragung mit geringstmöglichem Energieverlust für die Hochfrequenzleistung erfolgen kann und die zugelassene Genauigkeitsgrenze des kapazitiven Spannungswandlers bei angeschlossener und nicht angeschlossener Hochfrequenzsignalübertragung nicht überschritten wird.commonly connected to terminals A 1 and A 2 , this resistor can be included in the sealable part of the capacitive voltage converter, so that only terminals A 1 and A 2 remain freely accessible from the outside for connecting the HF components without the danger unauthorized interventions that impair the measurement accuracy.
