Description
lyießeinrichtung zur Feststellung der in verschiedenen Richtungen verlaufenden Anteile eines Wechselstromes. Es ist in mit Wechselstrom betriebenen Anlagen zuweilen von Interesse, die Anteile des Gesamtstromes zu messen, die auf die verschiedenen Stromrichtungen entfallen. Namentlich besteht dieses Interesse bei Anlagen, die mit gleichgerichtetem Wechselstrom arbeiten, wobei die verschiedenen Stromteile verschiedenen Kreisen zugeführt werden.liesseinrichtung to determine the in different directions running parts of an alternating current. It is in AC powered Systems sometimes of interest to measure the proportions of the total current that are on the different current directions are omitted. This interest exists in particular in systems that work with rectified alternating current, with the various Power parts are fed to different circuits.
Gemäß der Erfindung ist die Aufgabe dadurch gelöst, daß in dem .Stromkreis parallel zueinander zwei amperemetrische Gleichstrommeßgeräte angeordnet sind und mit jedem davon eine Ventilvorrichtung derart in Reihe geschaltet ist, daß die Stromstöße je nach ihrer Richtung nur über :das eine oder das andere der Meßgeräte verlaufen.According to the invention, the object is achieved in that in the .Stromkreis two amperometric direct current measuring devices are arranged parallel to one another and with each of which a valve device is connected in series in such a way that the current surges depending on their direction only run over: one or the other of the measuring devices.
Auf der Zeichnung ist in Abb. i ein Ausführungsbeispiel des Gegenstandes der Erfindung schematisch dargestellt.On the drawing in Fig. I is an embodiment of the subject of the invention shown schematically.
An eine Wechselstromq@uelle w sind über einen Transformator t und einen Gleichrichter g zwei Röntgenröhren r1, r2 angeschlossen, deren jeder Strom eines bestimmten Vorzeichens zugeführt wird. In die primären Anschlußleitungen des Transformators t sind parallel zwei Stromwege eingeschaltet, deren jeder aus einem Gleichstrommeßgerät m und einer damit in Reihe geschalteten Ventilröhre v besteht. Die Ventilröhren sind entgegengesetzt geschaltet; demzufolge fließt der Strom je nach seiner momentanen Polarität über das eine oder (las andere .der Meßgeräte in. Ihre Ausschläge lassen erkennen. welche Anteile die Stromstöße,der einen und der anderen Richtung an der Gesamtleistung haben. Dementsprechend können die beiden Röntgenröhren durch Einstellung der Heizstromstärke der. Kathode derart geregelt werden, daß sie eine gleiche Leistung aufnehmen.An alternating current source w is connected to a transformer t and a rectifier g connected two x-ray tubes r1, r2, each of which has a current a certain sign is supplied. In the primary connection lines of the Transformer t two current paths are switched on in parallel, each of which consists of one DC current meter m and a valve tube v connected in series with it. The valve tubes are connected in opposite directions; consequently the current flows ever according to its current polarity over one or (read other. of the measuring devices in. Their rashes reveal. what proportions the power surges, the one and the have another direction in terms of overall performance. Accordingly, the two can X-ray tubes by setting the heating current strength of the. Cathode regulated in this way that they absorb an equal performance.
An Stelle der beiden Gleichstrommeßgeräte kann man auch ein einziges Meßgerät der Ouotientenmessertype benutzen.Instead of the two direct current measuring devices, you can also use a single one Use a measuring device of the ouotient type.
Aj,b.2 zeigt schematisch eine derartige Anordnung, in der ein Kreuzspulenmeßgerät k verwendet wird, dessen Spulen sl, s. in Reihe mit den Ventilröhren v liegen. Wenn ein derartiges Meßgerät einen Ausschlag zeigt, ist die Leistung auf die beiden Stromrichtungen ungleich verteilt. Es muß dann so lange geregelt werden, bis der Zeiger in die Nullstellung zurückkehrt.Aj, b.2 schematically shows such an arrangement in which a cross-coil measuring device k is used, whose coils sl, see are in series with the valve tubes v. if such a measuring device shows a deflection is the power on the two current directions unevenly distributed. It must then be regulated until the pointer is in the zero position returns.
