   Durch das Umlegen des Kontaktfeldes durch den Thermostaten S wird Kontakt 27   go.   öffnet und der Erdschluss vollst1 ndig aus dem System ausgeschaltet. infolgedessen kommt auch 
 EMI3.1 
 gestellt. Ferner wird an Stelle des ordnungsgemässen Ruhestromes, welcher wie bereits schon erwähnt, über Kontakt 27 fliesst, folgender Ruhestromkreis geschlossen: A, X, 46, D, F, 57, 85, 33, 64, 59, 14, 41, a2, Melder Ii, a3, Ankerstück u3, 18, a4, Melder III, a5, 42, Ankerstück u4, 43, Magnet F, Kontakt 7,4, Magnet B, A. 



   Die Melder II bzw. III werden bei der Signalgebung in der oben beschriebenen Weise die Signalempfänger D, E zum Ansprechen bringen, nur mit dem Unterschied, dass die Signalströme nicht mehr über Kontakt 27, sondern über Kontakt 33 verlaufen, im übrigen bleibt die Signalgebung die gleiche. 



   Der in seiner Zuleitung gestörte Melder   I   wird bei der Signalgebung die Hilfsvorrichtung V,   pI,   L1 zum Ansprechen bringen. 



   Im Ruhezustande ist diese Hilfsvorrichtung nicht erregt, indem Ströme von Batterie   Z\   obere Wicklung des Magneten V, 66, 31, 25 zur Erdschlussstelle bzw. über die untere Wicklung 
 EMI3.2 
 dienen dazu, diese Ströme auszugleichen, so dass der Magnet V für gewöhnlich nicht anspricht. 



   Erst bei einer Erdung bei   T\   d. h. also bei der Signalgebung wird dieses   elpktromagnetische     Gleichgewicht   des Magneten V gestört, so dass infolge der Schwingungen des Ankers v und die hiedurch bewirkten Lokalströme über Lampe pI die Signalgebung erfolgt.

   When the thermostat S flips the contact field, contact 27 becomes go. opens and the earth fault is completely switched off from the system. as a result also comes
 EMI3.1
 posed. Furthermore, instead of the proper closed-circuit current, which, as already mentioned, flows via contact 27, the following closed-circuit circuit is closed: A, X, 46, D, F, 57, 85, 33, 64, 59, 14, 41, a2, detector Ii, a3, anchor piece u3, 18, a4, detector III, a5, 42, anchor piece u4, 43, magnet F, contact 7.4, magnet B, A.



   The detectors II and III will cause the signal receivers D, E to respond when signaling in the manner described above, with the only difference that the signal currents no longer run via contact 27 but via contact 33 same.



   The detector I, which is disturbed in its supply line, will cause the auxiliary device V, pI, L1 to respond when signaling.



   In the idle state, this auxiliary device is not energized, as currents from battery Z \ upper winding of magnet V, 66, 31, 25 to the earth connection point or via the lower winding
 EMI3.2
 serve to balance these currents so that the magnet V usually does not respond.



   Only when grounding at T \ d. H. Thus, during the signaling, this electromagnetic equilibrium of the magnet V is disturbed, so that the signaling takes place as a result of the oscillations of the armature v and the local currents caused by this via lamp pI.

 

Claims (1)

PATENT-ANSPRUCH : EMI3.3 dadurch gekennzeichnet, dass im Falle des Auftretens eines unvorhergesehenen Erdschlusses in einer der Melderleitungen diese aus dem Stromkreis ausgeschaltet und ihr Melder mit einer Hilsanzeigevorrichtung (r, LI, PI) verbunden wird und gleichzeitig die durch Ausschaltung genannter Leitung entstehende Lücke geschlossen wird, so dass die in den ungestört verbleibenden Leitungen befindlichen Melder ihre Signale auch weiterhin zur Hauptsignalvorrichtung zu senden vermögen. PATENT CLAIM: EMI3.3 characterized in that in the event of an unforeseen earth fault in one of the detector lines, it is switched off from the circuit and its detector is connected to an auxiliary display device (r, LI, PI) and at the same time the gap created by switching off said line is closed so that the Detectors located in the undisturbed lines continue to be able to send their signals to the main signal device.
