Description
Einrichtung zur Zündung eines Quecksilberdampf-Lichtbogens Ein Quecksilberdampf-Lichtbogen im Vakuum läßt sich bekanntlich dadurch zünden, daß in unmittelbarer Nähe des Otiecksilberspiegels ein hohes, zum Quecksilberspiegel gerichtetes Spannungsgefälle erzeugt wird. Dieses Spannungsgefälle wird bei Glaskolben mittels eines den- Kolben in der Ebene des Quecksilberspiegels von außen umspannenden Metallbandes, das an eine hohe elektrische Spannung gelegt wird, erzeugt. Ein Nachteil dieser Anordnung ist die Beschränkung ihrer Anwendbarkeit auf Glaskolben.Device for igniting a mercury vapor arc A mercury vapor arc It is known that in a vacuum it is possible to ignite in the immediate vicinity of the silver mirror a high voltage gradient directed towards the mercury level is generated. This In the case of glass bulbs, the voltage gradient is determined by means of a den bulb in the plane of the Mercury level from the outside encircling metal tape that is connected to a high electrical level Voltage is applied, generated. A disadvantage of this arrangement is the limitation their applicability to glass bulbs.
Gegenstand der Erfindung ist eine Zündvorrichtung, die im Prinzip gleich wirkt wie das Metallband, jedoch im Innern des Kolbens angebracht wird und daher auch in Metallkesseln verwendet werden kann.The invention is an ignition device, which in principle has the same effect as the metal band, but is attached inside the piston and therefore it can also be used in metal kettles.
Die Zündanordnung besitzt z. B. einen von einem festen Dielektrikurn (vorzugsweise' von Glas oder einem gleichwertigen Material) umschlossenen Leiter, welcher im Otiecksüberniveau so befestigt wird, daß, wenn er an Spannung liegt, an der Berührungsstelle zwischen dem festen Dielektrikum, dem Vakuum und dem Quecksilbereine große Feldstärke entstehen kann.The ignition arrangement has z. B. one of a solid dielectric conductor enclosed (preferably by glass or an equivalent material), which is fixed in the otieck over level in such a way that, when it is under tension, at the point of contact between the solid dielectric, the vacuum and the mercury large field strength can arise.
Die Abb. i und 2 der Zeichnung zeigen in Seitenansicht bzw. in Draufsicht ein Ausführungsbeispiel des Erfindungsgegenstandes.Figs. I and 2 of the drawing show a side view and a plan view, respectively an embodiment of the subject matter of the invention.
Ein gewelltes, mit Quecksilber 2 gefülltes Glasrohr i ist zu einem Ring geschlossen, dessen Mittelebene mit dem Quecksilberspiegel 3 zusammenfällt. Ein Glasrohr d. durchstößt den Boden des Kessels 7 in der Dichtung 5; am einen Ende mündet es in den Zündring i und am andern tr ägt es die Klemme 6, die durch die Ouecksilberfüllung 2 des Rohres 4 mit dem Öueclcsilberkern des Zündringes i leitend verbunden ist. Durch Anlegen einer hohen Spannung an die Klemme 6 wird die Zündung des Lichtbogens eingeleitet. Der Leiter 2 durchstößt .infolge seiner welligen Form den Quecksilberspiegel an vielen Stellen; es wird daher, auch wenn der Quecksilberspiegel sich bewegt, immer mehrere Stellen des Leiters geben, die eine für das Zünden günstige Lage einnehmen.A corrugated glass tube i filled with mercury 2 becomes one Ring closed, the center plane of which coincides with the mercury level 3. A glass tube d. penetrates the bottom of the boiler 7 in the seal 5; at one end it opens into the ignition ring i and on the other it carries the terminal 6, which passes through the Mercury filling 2 of the tube 4 with the oil core of the ignition ring i conductive connected is. By applying a high voltage to terminal 6, the ignition of the arc initiated. The conductor 2 punctures due to its wavy shape the mercury level in many places; it will therefore, even if the mercury level moves, always give several places on the conductor, the one favorable for the ignition Take position.
