Description

Bei Schwachstromanlagen, welche durch eine Akkumulatorenbatterie gespeist werden und bei welchen die Batterie zwecks Aufladung dauernd an ein Starkstromnetz ange-S schlossen ist, besteht die Gefahr, daß bei beschädigter Batterie die Spannung des Starkstromnetzes auf die Schwachstromanläge übertritt. Diese Gefahr wird durch den Gegenstand der vorliegenden Erfindung dadurch behoben, daß parallel zur Batterie eine der Batteriegröße entsprechendeAnzahl Polarisationszellen geschaltet werden. For low-voltage systems that are fed by an accumulator battery and in which the battery is permanently connected to a high-voltage network for charging is closed, there is a risk that if the battery is damaged, the voltage of the high-voltage network transfers to the low-voltage systems. This danger is caused by the subject Solved the present invention in that parallel to the battery one of the battery size corresponding number of polarization cells are switched.

Die Zeichnung gilbt das Schaltbild einer Ausführungsform wieder. Es bezeichnet a eine das Schwachstramnetz m speisende Akkumulatorenbatterie, welche zwecks Ladung dauernd am1 Starkstromnetz η angeschlossen ist. w ist ein Vorsahaltwiderstand, welcher den Ladestrom auf das zulässige Maß herabsetzt, ρ sind die Palarisationszellen, welche der Batterie α parallel geschaltet sind, r bezeichnet ein in Reihe mit den Polarisationszellen p liegendes Relais und s eine Schmelzsicherung. Während bei intakter Batterie a durch die Polarisationszellen p kein Strom fließt, erhöht sich bei Stromunterbreohung im Batteriestromkreis in die Spannung an denThe drawing is the circuit diagram of an embodiment again. It refers to a weak one, the tram network m supplying storage battery which is connected in order to charge continuously at 1 η power network. w is a series resistor which reduces the charging current to the permissible level, ρ are the polarization cells which are connected in parallel to the battery α , r denotes a relay lying in series with the polarization cells p and s a fuse. While in intact battery A by the polarization p cells, no current flows, is increased with Stromunterbreohung in the battery circuit in the voltage at the

Punkten c und d derart, daß nunmehr durch die Polarisationszelen p und somit auch durch das Relais r Strom fließt, so daß die Siehe- 3° rung s zum Scbmeken gebracht und damit die Starkstromleitung η von der Schwachstrotnleitungm getrennt wird, Die Schmelzsicherung.? kann auch durch beliebige andere stromunterbrechende Mittel, wie beispiels- 35 weise Relais, Ouecksillberkontakte o. dgl., ersetzt werden.Points c and d in such a way that it is now p by the Polarisationszelen and thus flows through the relay r current so that the Siehe- 3 ° tion s brought to Scbmeken and thus the power line η is separated from the Schwachstrotnleitungm The fuse.? can also be replaced by any other current-interrupting means, such as relays, Ouecksilberkontakte or the like.
