Description

Verfahren zur Strombegrenzung beim Betriebe elektrischer Gasreiniger. Die Erfindung betrifft ein Verfahren zur Strombegrenzung beim Betriebe elektrischer Gasreiniger. Gemäß der Erfindung wird die Eigenschaft der Glühkathodenröhren, bei einer bestimmten Heizstromstärke unabhängig von der Anodenspannung nur einen bestimmten Sättigungsstrom hindurchzulas-#,en, in der Weise benutzt, daß eine Glühkathodenröhre in den Stromkreis der elektrischen Niederschlagsanlage eingeschaltet und ihr Heizstrom so geregelt wird, daß die Röhre nur von einem Strom durchflossen werden kann, der eine Funkenentladung bzw. eine Lichtbogenbildung im elektrischen Niederschlagsraum ausschließt. Auf diese Weise ergibt sich ein sicherer Betrieb insbesondere für solche elektrische Niederschlagsanlagen, die zur Abscheidung und Niederschlagung von brennbarem oder explosiblem Staub, z. B. Kohlenstaub, dienen.Procedure for current limitation when operating electrical gas purifiers. The invention relates to a method for limiting current when operating electrical Gas purifier. According to the invention, the property of the hot cathode tubes is at a certain heating current strength independent of the anode voltage only a certain one Saturation current through - #, en, used in such a way that a hot cathode tube switched into the circuit of the electric precipitation system and its heating current is regulated so that the tube can only be traversed by a current that a spark discharge or arcing in the electrical precipitation area excludes. In this way, safe operation results, especially for such electric precipitation systems used for the separation and suppression of combustible or explosive dust, e.g. B. coal dust, serve.

eben ihrer Wirkung als Strombegrenzer kann die Glühkathodenröhre in bekannter Weise zugleich als Gleichrichter von hochgespanntem Wechselstrom verwendet werden, wobei die zu diesem Zweck bekannten Schaltungen, z. B. die Graetzsche Schaltung, benutzt -werden.The hot cathode tube can act as a current limiter As is known, it is also used as a rectifier for high-voltage alternating current the circuits known for this purpose, e.g. B. the Graetz circuit, to be used.

Die Glühkathodenröhre kann an beliebiger Stelle in den Stromkreis eingeschaltet sein; am vorteilhaftesten ist ihre Einschaltung vor den Sprühelektroden.The hot cathode tube can be placed anywhere in the circuit to be on; it is most advantageous to switch them on before the spray electrodes.
