Description
Einrichtung zum Vergleichen mehrerer Wechselstromgrößen miteinander, insbesondere zum Synchronisieren zweier Leitungssysteme In dem Hauptpatent ist eine Einrichtung zum Vergleichen mehrerer elektrischer Wechselstromgrößen miteinander, insbesondere zum Synchronisieren zweier Leitungssysteme, dahingehend beschrieben, daß beiden miteinander zu vergleichenden Leitungen von diesen elektrisch gesteuerte, mechanische Bewegungen ausführende Schwingsysteme zugeordnet sind, aus deren Schwingungen auf die elektrischen Verhältnisse der miteinander zu vergleichenden Leitungssysteme geschlossen werden kann.Device for comparing several alternating current quantities with one another, in particular for synchronizing two line systems Device for comparing several electrical alternating current quantities with one another, in particular for synchronizing two line systems, described to the effect that that the two lines to be compared are electrically controlled by them, Oscillation systems executing mechanical movements are assigned, from their oscillations on the electrical conditions of the line systems to be compared can be closed.
Andererseits ist es bekannt, bei Vorrichtungen zum Vergleichen zweier elektrischer Wechselstromgrößen miteinander die Vergleichsvorrichtung an regelbare Ohmsche Widerstände anzuschließen, die über kapazitive Spannungsteiler in Form von Hängekettenisola.foren an die Vergleichsleitung angeschlossen sind. Diese Widerstände -dienen dabei nur, um die Spannungen zu vergleichen.On the other hand, it is known in devices for comparing two electrical alternating current variables with each other the comparison device to controllable Connect ohmic resistors, which are made via capacitive voltage dividers in the form of Hängeketteisola.foren are connected to the comparison line. These resistances - are only used to compare the tensions.
Legt man die gesteuerten Systeme (Schwingsysteme und Elektroden) der Einrichtung nach dem Hauptpatent über kapazitive oder induktive Anschlüsse an die Netzleitung, so können in diesen Zuleitungen durch die Verschiedenheit der Anschlüsse bezüglich ihrer Induktivität und Kapazität Phasenverschiebungen auftreten. Ferner können auch die verschiedenen mechanischen Eigenschaften der Schwingsysteme eine mechanische Phasenverschiebung der Systeme gegeneinander hervorrufen. Durch diese Unstimmigkeiten zwischen den beiden gesteuerten Systemen werden einwandfreie Angaben dieser Meßvorrichtung für Synchronismus unmöglich bzw. in Frage gestellt.If you put the controlled systems (oscillating systems and electrodes) of the Device according to the main patent via capacitive or inductive connections to the Mains line, so can in these supply lines due to the difference in connections phase shifts occur with regard to their inductance and capacitance. Further The various mechanical properties of the oscillating systems can also be one cause mechanical phase shift of the systems against each other. Through this Discrepancies between the two controlled systems become flawless information this measuring device for synchronism impossible or called into question.
Um diese Übelstände zu beheben, wird erfindungsgemäß in mindestens eine Zuleitung zu den gesteuerten Systemen eine elektrische Phasenabgleichvorrichtung aus einstellbaren Kapazitäten und Widerständen und gegebenenfalls Selbstinduktionen oder einem Transformator mit festem oder regelbarem übersetzungsverhältnis eingeschaltet. Mit Hilfe dieser Abgleichvorrichtung kann erreicht werden, daß zwischen den Schwingungen der gesteuerten Systeme keinerlei Phasenverschiebung besteht. Gleichzeitig kann dabei auch die Höhe der an jedes System anzulegenden Spannung eingestellt werden.In order to remedy these deficiencies, according to the invention in at least a feed line to the controlled systems an electrical phasing device from adjustable capacitances and resistances and, if necessary, self-induction or a transformer with a fixed or adjustable gear ratio is switched on. With the help of this balancing device it can be achieved that between the oscillations there is no phase shift in the controlled systems. At the same time can the amount of voltage to be applied to each system can also be set.
In der Abbildung ist ein Ausführungsbeispiel gemäß der Erfindung dargestellt. Zwischen dem kapazitiven Anschluß an die Netzleitung und Erde ist für das System V U die Abgleichvorrichtung 59 eingeschaltet, bestehend aus einstellbaren Kapazitäten 6o, 61 und einstellbaren Widerständen 62, 63, gegebenenfalls unter Zuhilfenahme von Selbstinduktionen. Von dieser Abgleichvorrichtung wird die Spannung für das gesteuerte System des Leitungssystems abgegriffen. Durch Verschieben des Abgriffpunktes 65 kann die elektrische und mechanische Korrektion bezüglich der Phasenverschiebung des Systems 64 gegenüber dem anderen System 65 vorgenommen werden.In the figure, an embodiment according to the invention is shown. Between the capacitive connection to the power line and earth, the balancing device 59 is switched on for the system VU, consisting of adjustable capacitors 60, 61 and adjustable resistors 62, 63, possibly with the aid of self-inductions. The voltage for the controlled system of the line system is tapped from this balancing device. By shifting the tapping point 65, the electrical and mechanical correction with regard to the phase shift of the system 64 with respect to the other system 65 can be carried out.
Dieses andere System 65 ist über Schleifbürsten 66 an den in der Leitungsphase X Y liegenden Widerstand 67, der in der Mitte geerdet sein kann, angeschlossen. Durch Verschieben der Schleifbürsten läßt sich die Höhe der Spannung für dieses Schwingsystem einstellen. An Stelle des Widerstandes 67 kann auch ebenso ein Transformator mit festem oder regelbarem Übersetzungsverhältnis tre# ten. Die beiden Systeme 64 und 65 sind nach dem Hauptpatent an eine Polarisationsbatterie i9 angeschlossen.This other system 65 is connected via brushes 66 to the resistor 67 which is in the line phase XY and which can be grounded in the middle. The level of tension for this oscillating system can be adjusted by moving the brushes. Instead of the resistor 67 , a transformer with a fixed or adjustable transformation ratio can also be used. According to the main patent, the two systems 64 and 65 are connected to a polarization battery 19.
Es ist auch möglich, für beide gesteuerte Systeme Abgleichvorrichtungen in den Zuleitungen vorzusehen.It is also possible to use balancing devices for both controlled systems to be provided in the supply lines.
