Description

  

   <Desc/Clms Page number 1> 
 



    Einrichtung zur Verhütung von fester Kesselsteinbildung und Materialanfressungen in Dampfkessel, Kondensatoren und ähnlichen Behältern auf elektrischem Wege.   
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 
Die Lampe L brennt in diesem Falle weiter, nachdem ja die beiden Sicherungen   81   und   82   unversehrt sind. 
 EMI2.1 
 
Durchbrennen der Sicherungen unter keinen Umständen statt, da die Lampe mit dem Kessel und der Erdleitung in Reihe geschaltet ist. Der durch den Kessel gehende Strom ist jedoch auch in diesem Falle zu gross und bleibt unwirksam, wenn der Erdschluss ein vollständiger ist. 



   Es ist deshalb notwendig, auch in den zweiten Leitungszweig des Nebenschlusses eine Signallampe od. dgl. einzuschalten, wie dies in Fig. 4 dargestellt ist. Hier ist mit Li die eine und mit   L2   die andere
Signallampe bezeichnet und man sieht, dass bei normalem Betrieb beide Lampen mit halber Lichtstärke leuchten und bei einem Erdschluss in einem oder andern Leitungszweig die betreffende Lampe sofort mit voller Lichtstärke leuchtet, während die andere Lampe sofort erlischt, wodurch das Bedienungspersonal auf die eingetretene Betriebsstörung aufmerksam wird. 



   PATENT-ANSPRÜCHE :
1. Einrichtung zur Verhütung von fester Kesselsteinbildung und Materialanfressungen in Dampf- kesseln, Kondensatoren oder   ähnlichen   Behältern auf elektrischem Wege, gekennzeichnet durch einen von beiden Leitern eines Gleichstromnetzes abgezweigten Stromkreis   (a, < < 1'b1, b),   dessen   regulierbarem  
Widerstande (W) der Kessel durch'Anlegen der Polenden an den Kesselmantel parallel geschaltet ist, wobei zwischen dem regulierbaren Widerstande (W) und dem Leitungsnetz in den Stromkreis   (a,     al,   bl, b) Widerstände in Form konstanter Lampenwiderstände eingeschaltet sind.

    Device for the prevention of solid scale formation and material corrugation in steam boilers, condensers and similar containers by electrical means.
 EMI1.1
 

 <Desc / Clms Page number 2>

 
The lamp L continues to burn in this case after the two fuses 81 and 82 are intact.
 EMI2.1
 
Under no circumstances will the fuses blow, as the lamp is connected in series with the boiler and the earth line. However, the current flowing through the boiler is too high in this case too and remains ineffective if the earth fault is a complete one.



   It is therefore necessary to switch on a signal lamp or the like in the second branch of the shunt, as shown in FIG. Here is one with Li and the other with L2
Signal lamp and you can see that during normal operation both lamps light up at half light intensity and in the event of an earth fault in one or the other branch of the line, the relevant lamp immediately lights up with full light intensity, while the other lamp goes out immediately, whereby the operating personnel is made aware of the malfunction .



   PATENT CLAIMS:
1. Device to prevent solid scale formation and material seizure in steam boilers, condensers or similar containers by electrical means, characterized by a circuit branched off from both conductors of a direct current network (a, <<1'b1, b), its adjustable
Resistors (W) of the boiler is connected in parallel by applying the pole ends to the boiler shell, with resistors in the form of constant lamp resistances being switched on between the adjustable resistors (W) and the line network in the circuit (a, al, bl, b).

Claims (1)

2. Einrichtung nach Anspruch 1, dadurch gekennzeichnet, dass die Lampenwiderstände auf beide Anschlussleitungen des Stromkreises (a, a"b"b) verteilt sind, so dass diese Lampen gleichzeitig als Signal- lampen fqr Erdschluss dienen. EMI2.2 2. Device according to claim 1, characterized in that the lamp resistances are distributed over both connection lines of the circuit (a, a "b" b), so that these lamps simultaneously serve as signal lamps for earth faults.
