Für die von den Relais betätigten Alarmvorrichtungen ist man genötigt, besondere Hilfsstromquellen zu benutzen, da die Benutzung des Netzes als unmittelbare oder mittelbare Stromquelle infolge Gefahr des Zusammenbruches der benutzten Spannung bei Kurzschluß sich verbietet. Man benutzt im allgemeinen als Hilfsstromquelle Gleichstrombatterien, deren Ladung und Instandhaltung eine unerwünschte Zugabe zu der Bedienung to der Anlage bieten.For the alarm devices activated by the relays one is forced to use special auxiliary power sources because the use of the network as a direct or indirect power source due to the risk of collapse the voltage used is prohibited in the event of a short circuit. One uses in general as an auxiliary power source DC batteries, their charging and maintenance offer an undesirable addition to the operation of the system.
Gemäß der Erfindung wird als Stromquelle ein Kondensator verwendet, der über einen Gleichrichter von dier zu schützenden LeitungAccording to the invention, a capacitor is used as a power source, which has a Rectifier of the line to be protected

aus aufgeladen wird. Die Erfindung eignet sich, besonders für solche Relais, die ohnedies nur kurzzeitigen Kontakt machen, wie z. B. für Erdschlußrelais, die so geringe Dämpfung haben, .daß sie auf intermittierende Erdschlüsse ansprechen. Die Abbildung zeigt ein derartiges Erdschlußrelais i, das in bekannter·, daher nicht weiter angegebener Weise geschaltet ist. Es gibt beim Ansprechen auf ίο eine bestimmte Energierichtung, bei der der Fehler in. dem zu überwachenden Leitungsstück liegt, einen momentanen Kontakt bei 2. Durch diesen Kontakt wird ein Stromkreis geschlossen, der die Spule 3 des Signalgeiä,tes, beispielsweise einer Fallklappe, und einen Kondensator enthält. Der Kondensator wird dann mehr oder weniger durch die Spule 3 während der Zeit des Kontaktes bei 2 entladen und setzt die Fallklappe in Tätigkeit. Die Ladung des Kondensators 4 geschieht gemäß der Erfindung aus dem Netz 5, und' zwar wird meist, wie in der Abbildung, ein Spannungswandler 6 zwischengeschaltet sein. Die Ladung geschieht nach der Erfindung über einen Gleichrichter irgendwelcher Art, beispielsweise eine Glimmlampe. 7. Hierdurch wird verhindert, daß die Spannung des Kondensators der Spannung des Leitungsnetzes folgt, also deren periodische Schwankungen mitmacht und im Falle eines Kurzischlusses zwischen den beiden Leitungen, an die der Kondensator 4 oder Wandler 6 gelegt ist, verschwindet. Bei Einbau des Gleichrichters. 7 wird der Kondensator 4 auf den Scheitelweirt der speisenden Spannung in der Figur deir Sefcundärspannung des Wandlers 6 geladen und bleibt geladen, auch wenn die speisende Spannung z. B. bei einem Kurzschluß zwischen den Anschlußpunkten des Transformators 6 an die Leitung 5 verschwindet. Ein solcher Kurz-Schluß ist eine Möglichkeit, mit der stets gerechnet werden muß, da der Kurzschluß gemeinsam mit Erdschluß auftreten kann. Der Kondensator 4 wird zweckmäßig so groß gewählt, daß seine Spannung während der Dauer der Kontaktgabe bei 2 nicht zu sehr abnimmt. Um die Wirkung in der Signalspule 3 zu vergrößern, ist in dem Ausführungsbeispiel in bereits anderweitig vorgeschlageiner Weise der Signalspule ein weiterer Kondensator 9 mit einem Strombegirenzunigswideirstand 19, parallel geschaltet. Dieser lädt sich dann während der Kontaktgabe bei 2 und 'entlädt sich nach Aufhören des Kontaktes durch die Spule 3, wodurch eine langer dauernde und kräftigere Wirkung der Spule hervorgerufen wird. In dieser Schaltung ist der Kondensator 9 vorzugsweise kleiner genommen als der Kondensator 4, damit die. Spannung des Kondensators 4 bei der Entladung in die Spule 3 und den Kondensator 9 nicht zu sehr abfällt.from being charged. The invention is particularly suitable for such relays that anyway only make short-term contact, such as B. for earth fault relays, the so low attenuation that they respond to intermittent earth faults. The illustration shows a such a ground fault relay i, which is switched in a known manner, therefore not further specified is. When responding to ίο there is a certain direction of energy in which the There is a fault in the line section to be monitored, a momentary contact at 2. This contact closes an electrical circuit that causes coil 3 of the signal device for example a drop flap, and a condenser. The capacitor will then more or less discharged through the coil 3 during the time of contact at 2 and activates the drop flap. The capacitor 4 is charged in accordance with the invention from the network 5, namely 'is mostly, as in the figure, a voltage converter 6 be interposed. The charging happens according to the invention via a rectifier of some kind, for example a glow lamp. 7. This prevents the voltage on the capacitor the voltage of the line network follows, so participates in their periodic fluctuations and in the event of a short circuit between the two lines to which the capacitor 4 or converter 6 is connected disappears. When installing the rectifier. 7 the capacitor 4 is on the vertex value the feeding voltage in the figure deir secondary voltage of the converter 6 loaded and remains charged, even if the supply voltage z. B. in a short circuit between the connection points of the transformer 6 the line 5 disappears. Such a short circuit is a possibility that is always expected must be, since the short circuit can occur together with the earth fault. The capacitor 4 is expediently chosen so large that that its voltage does not decrease too much during the duration of the contact at 2. In order to increase the effect in the signal coil 3, FIG a further capacitor 9 has already been proposed in another way for the signal coil a Strombegirenzunigswideirstand 19, in parallel switched. This then charges while making contact at 2 and 'discharges itself afterwards Cessation of contact by the coil 3, creating a longer lasting and stronger Effect of the coil is caused. In this circuit, the capacitor 9 is preferred taken smaller than the capacitor 4, so that the. Voltage of the capacitor 4 does not drop too much during the discharge into the coil 3 and the capacitor 9.
