Description

Fernüberwachung von unbedienten elektrischen Gleichrichteranlagen Die Erfindung bezieht sich auf bedienungslos arbeitende Signaleinrichtungen, die durch Gleichstrom betätigt werden, wobei der Strom beispielsweise aus einer überlandzentrale über einen Gleichrichter entnommen wird. Der Gleichrichter kann die Energie direkt an die Signaleinrichtung abgeben, er kann aber in bekannter Weise auch über eine Akkumulatorenbatterie arbeiten. Erfindungsgemäß soll die Betriebsfähigkeit der -Anlage an einer Stelle, die entferrit von der Signaleinrichtung sich befindet, überwacht werden, wobei es nicht nur darauf ankommt, den Zustand bzw. das einwandfreie Arbeiten des Gleichrichters, sondern auch die Zuführung des Wechselstromes zu kontrollieren. Hierbei ist es erwünscht, die Anzahl der Zuführungsleitungen zu dem Meßinstrument an der überwachungsstelle möglichst gering zu halten. Hierzu werden nach der Erfindung nur zwei Leitungen benötigt. Die eine Leitung kann auch als Erdleitung ausgeführt werden. Außerdem können in diese Leitungen an die Anzeigegeräte zum Schutz derselben Kondensatoren und (oder) Drosselspulen gelegt werden.Remote monitoring of unattended electrical rectifier systems The invention relates to unattended signaling devices that operated by direct current, the current for example from an overland control center is taken through a rectifier. The rectifier can direct the energy to the signaling device, but he can also in a known manner via a Accumulator battery work. According to the invention, the operability of the system at a point that is far from the signaling device, monitored , whereby it is not just a matter of the condition or the flawless work of the rectifier, but also to control the supply of alternating current. It is desirable here to determine the number of feed lines to the measuring instrument to be kept as low as possible at the monitoring point. To this end, according to the invention only two lines required. One line can also be designed as an earth line will. In addition, these lines can be connected to the display devices to protect the same Capacitors and (or) reactors are placed.

Das Schaltschema zur Durchführung der Überwachung einer .derartigen Gleichrichteranlage ist in der Zeichnung dargestellt.The circuit diagram for carrying out the monitoring of such a The rectifier system is shown in the drawing.

In - der Abbildung wird der Signalstrom aus dem mit i angedeuteten Drehstromnetz entnommen und einem Transformator 2 zugeführt. Die Sekundärseite des Transformators arbeitet über den Gleichrichter 3 in das für die Signalbetätigung benutzte Netz ¢. Durch die Leitungen 5 wird der Wechselstrom, durch die Leitung 6 der Gleichstrom überwacht. Der Wechselstrom wird über einen Kondensator 7, der Gleichstrom mittels eines Widerstandes io über eine Drossel 8 dem Überwachungsapparat durch dieselben .Leitungen 9 zugeführt. Durch diese Anordnung ist es möglich, nur mit zwei Leitungen auszukommen.In the figure, the signal current is derived from the one indicated by i Taken from the three-phase network and fed to a transformer 2. The secondary side of the Transformer works via the rectifier 3 in that for signal actuation network used ¢. The alternating current flows through the lines 5, through the line 6 the direct current is monitored. The alternating current is via a capacitor 7, the Direct current by means of a resistor io via a choke 8 to the monitoring apparatus through the same .Leitungen 9 supplied. With this arrangement it is only possible get by with two lines.
