Description
Hochfrequenzzündgerät für Hochdruck-Dampf- oder Gasentladungslampen Zur Zündung von Hochdruck-Entladungslampen mit Gas- oder Dampffüllung, wie Xenon- und Quecksilberdampf-Hochdrucklampen, verwendetman meist ein Zündgerät, das aus einem Netzspannungstransformator und einem an diesen angeschlossenen Schwingkreis besteht, der zur Erzeugung hochfrequenter Schwingungen dient und einen Kondensator, eine Funkenstrecke und die Primärwicklung eines Hochfrequenztransformators enthält. Die Sekundärseite des Hochfrequenztransformators wird an die beiden Elektroden der Gasentladungslampe oder an eine Zündelektrode und eine Lampenelektrode angekoppelt. Bei Hochdruck-Gasentladungslampen mit hohen Betriebsströmen, insbesondere mit Strömen höher als 80 Ampere, ergeben sich für das Zündgerät große Abmessungen und hohes Gewicht.High-frequency igniter for high-pressure vapor or gas discharge lamps For igniting high-pressure discharge lamps with gas or vapor filling, such as xenon and high pressure mercury vapor lamps, an ignitor is usually used, which consists of a mains voltage transformer and an oscillating circuit connected to it consists, which is used to generate high-frequency vibrations and a capacitor, contains a spark gap and the primary winding of a high frequency transformer. The secondary side of the high-frequency transformer is connected to the two electrodes Gas discharge lamp or coupled to an ignition electrode and a lamp electrode. In the case of high-pressure gas discharge lamps with high operating currents, in particular with currents higher than 80 amps, the ignitor is large and tall Weight.
Die Erfindung bringt eine vorteilhafte Verbesserung an einem derartigen Zündgerät. Gemäß der Erfindung besteht der Hochfrequenztransformator aus mindestens zwei sekundärseitig parallelgeschalteten Einheiten. Auf diese Weise wird die Kühlfläche des Hochfrequenztransformators vergrößert, so daß man ihn höher belasten kann. Durch den sich hierbei ergebenden kleineren Kupferquerschnitt kann das Gewicht des Hochfrequenztransformators wesentlich herabgesetzt werden, wodurch sich die gesamten Abmessungen des Zündgerätes verkleinern. Damit kann das Zündgerät leichter als bisher gebaut und untergebracht werden.The invention brings an advantageous improvement to such Ignitor. According to the invention, the high frequency transformer consists of at least two units connected in parallel on the secondary side. In this way the cooling surface becomes of the high-frequency transformer enlarged so that you can load it higher. By the resulting smaller copper cross-section can be due to the weight of the high-frequency transformer can be significantly reduced, thereby increasing the overall dimensions of the igniter zoom out. This means that the ignition device can be built and accommodated more easily than before will.
In der Zeichnung ist ein schematisches Ausführungsbeispiel - dargestellt. Mit 1 ist der Netzspannungstransformator bezeichnet, an den sekundärseitig ein Schwingkreis angeschlossen ist, der den Kondensator 2, die Funkenstrecke 3 und die Primärwicklung des Hochfrequenztransformators H enthält. Der Hochfrequenztransformator besteht erfindungsgemäß aus drei sekundärseitig parallel geschalteten Einheiten 5, 6 und 7. Die Sekundärseiten dieser Einheiten sind an die eine Elektrode 11 der Lampe 10 und über den Kopplungskondensator 8 an die andere Elektrode 12 angeschlossen. Die Klemmen 13, 14 werden zur Speisung der Gasentladungslampe über ein nicht dargestelltes Vorschaltgerät an Netzspannung angeschlossen.A schematic exemplary embodiment is shown in the drawing. 1 with the mains voltage transformer is referred to, on the secondary side, a resonant circuit is connected, the capacitor 2, the spark gap 3 and the primary winding of the high frequency transformer H contains. The high frequency transformer exists according to the invention from three units 5, 6 and connected in parallel on the secondary side 7. The secondary sides of these units are connected to one electrode 11 of the lamp 10 and connected to the other electrode 12 via the coupling capacitor 8. the Terminals 13, 14 are used to feed the gas discharge lamp via a not shown Ballast connected to mains voltage.
Die einzelnen Einheiten 5, 6, 7 des Hochfrequenztransformators können primärseitig in Reihe geschaltet sein. Infolge des sich hierbei ergebenden sehr hochohmigen Schwingkreises muß man mit einer hohen Ausgangsspannung des Netztransformators 1 arbeiten. Dies kann dadurch vermieden werden, daß man die Einheiten des Hochfrequenztransformators sowohl primär- als auch sekundärseitig parallel schaltet.The individual units 5, 6, 7 of the high-frequency transformer can be connected in series on the primary side. As a result of the resulting very A high-impedance resonant circuit has to be connected to a high output voltage of the mains transformer 1 work. This can be avoided by removing the high frequency transformer units switches in parallel on both the primary and the secondary side.
Bisher benötigte man für den Hochfrequenztransformator eines Zündgerätes für eine Xenon-Kurzbogenlampe von 6 kW Leistung etwa 36 Kp Kupfer. Bei der erfindungsgemäßen Aufteilung des Hochfrequenztransformators in drei Einheiten sind für dasselbe Zündgerät nurmehr dreimal 2,25 Kp Kupfer erforderlich.Previously, an ignition device was required for the high-frequency transformer for a xenon short-arc lamp with an output of 6 kW, about 36 Kp copper. In the inventive Division of the high-frequency transformer into three units are for the same ignitor only three times 2.25 Kp copper required.
