Description
Die notwendige Einschaltung einer Drosselspule hat einen erheblichen Nachteil zur Folge, weil durch sie ein Blindstrom erzeugt wird. Aus leicht verständlichen Gründen verlangen aber die Elektrizitätswerke für Beleuchtungsanlagen eine induktionsfreie Arbeitsentnahme. Nach bisher vergeblichen Versuchen, eine zufriedenstellende Lösung zu finden, kam zwischen Stromerzeuger und Stromabnehmer eines Einigung dahingehend zustande, dass vor der Leuchtstofflampe ausser der Drosselspule und dem Glimmzünder zusätzlich noch ein Ausgleichskondensator eingeschaltet werden muss, Dieser Ausgleichskondensator kann nicht die Bedürfnisse befriedigen, weil einmal der verlangte Leistungsfaktor Bur annähernd erreicht wird, und zum anderen das Zusatzgerät die Gesamtkosten einer Leuchtstofflampe wesentlich erhöht. The necessary activation of a choke coil has a considerable impact Disadvantage as a consequence, because a reactive current is generated by them. Made easy to understand There are reasons, however, that the electricity companies require an induction-free system for lighting systems Work withdrawal. After unsuccessful attempts, a satisfactory solution to find, an agreement was reached between the electricity producer and the pantograph comes about that in front of the fluorescent lamp except for the choke coil and the glow igniter an equalizing capacitor must also be switched on, this equalizing capacitor cannot satisfy the needs because once the required power factor Bur is approximately achieved, and on the other hand the additional device the total cost of a Fluorescent lamp increased significantly.
DieaufgezeigtenSchwierigkeitenundNachteilezu beheben, hat die Erfindung zcst Zweck. Sie schlägt eine vereinfachte Schaltung vor, deren Wesen sich insbesondere dadurch kennzeichnet, dasa die Drosselspule aussohaltbar angeordnet ist, und bei dieser Ausschaltung ein Ohmscher Widerstand in den Lampenstromkreis eingeschaltet wird. The invention has to remedy the indicated difficulties and disadvantages primarily purpose. It proposes a simplified circuit, the essence of which is particular characterized in that the choke coil is arranged to be held in place, and at this switching off an ohmic resistor switched into the lamp circuit will.
Der Erfindungsgegenstand ist auf der Zeichnung bei spielsweise im Schema dargestellt. The subject of the invention is on the drawing for example in Scheme shown.
Die Erfindung geht von der Erkenntnis ases dit
Hat eine Lampe gezündet, so wird aus diesem Stromkreis die Drosselspule
2 in an sich bekannter Weise ausgeschaltet und unmittelbar darauf ein Ohasoher Widerstand
5 eingeschaltet, was eine induktionsfreie Arbeitsentnahme gewährleistet. Als sodcher
Widerstand 5 kann erfindungsgemäss eine Glühlawpe Verwendung
