Description

Bei Gasentladungsgefäßen wird bekanntlich der Lichtbogen: durch magnetische Felder, beispielsweise durch das eines in der Nähe befindlichen Stromleiters oder einer benachbarten, gleichzeitig brennenden Entladurgsstrecke beeinfiußt. Diese Beeinflussung wirkt in der Weise, daß die Anode und, der zur Verfügung stehende Entladungsquerschnitt auf dem Wege zur Anode, z. B. das Anodenschutzrühr , nicht gleichmäßig belastet werden. Mit dieser Erscheinung sind bekanntlich erhebliche Mängel besonders. bei hohen Stromdichten verbunden.As is well known, the arc is created in gas discharge vessels: by magnetic Fields, for example through that of a nearby conductor or an adjacent, simultaneously burning discharge line. These Influencing works in such a way that the anode and the one available Discharge cross-section on the way to the anode, e.g. B. the anode protection stirrer, not are evenly loaded. With this phenomenon are known to be considerable Defects especially. connected at high current densities.

Um diese Nachteirle zu vermeiden, ist. es bereits bekannt, durch ein zusätzliches Magnetfeld= auf den Lichtbogen derart einzuwirken, daß die vom magnetitschen. Störfeld aus verursa.chite Beeinflussung des Lichtbogens kompensiert wird. Um dies zu erreichen, wurden die Anodenstromzuführungen. derart um die Anode bzw. die Entladungsbahn geführt, daß die gewünschte Kompensation erfolgt. Dieser Lösungsweg ist jedoch auß-erordendich umständlieh.In order to avoid these night harassment is. it already known by a additional magnetic field = to act on the arc in such a way that the magnetite. Disturbance field from causa.chite influencing the arc is compensated. To this to achieve were the anode power supplies. around the anode or the discharge path led that the desired compensation takes place. However, this approach is extraordinary inconvenient.

Die vorliegende Effindung geht von der Erkenntnis aus, daß eine Umhüllung des Lichtbogenweges aus ferromagn.etischexri Material, z. B. bei Eisenstromri.chtern das Anodenschutzrohr, eine gute magnetische Abschirmung gegen äußere magnetische Felder ergeben; würde, wenn nicht durch. den darin fließenden Entladungsstrom diese ferromagneti:sche Hülle teilweise bis zur Sättigung vormagnetisiert würde, wodurch die Permeabifität so stark abnimmt, d!aß die abschirmende Wirkung aufgehoben wird:.The present invention is based on the knowledge that a cover the arc path made of ferromagn.eticxri material, e.g. B. at Eisenstromri.chtern the anode protection tube, a good magnetic shield against external magnetic Fields yield; would if not through. the discharge current flowing in it ferromagnetic shell would be partially premagnetized to saturation, whereby the permeability decreases so much that the shielding effect is canceled:

Um- eine derartige Sättigung des Anodenschutzrohres zu vermeiden, isst eine Anordnung zur Beeinfluissung eines Lichtbogens bei Quecksilberdampf-Entladungsgefäßen vorgesehen, bei der gemäß der Erfindung bei mehranodigen Gefäßen, die einzelnen Anodens.chutzrohre durch Dauermagnete derart miteinander verbunden sind, da ß sie in Querrichtung magnetisch polarisiert sind. Diese Maßnahme wird dadurch getroffen, däß ein Nord und Südpol eines Dauermagneten an. entgegengesetzten Seitenwandungsteilen des aus ferromagnetischen Material bestehenden Schutzrohres angelegt. werden. Selbstverständlich muß dias magnetische Kraftfeld des Schutzrohres größer sein als das, -das durch die Entladung selbst erzeugt wird, um eine wirksame Beeinflussung durch ein äußeres Störfeld zu vermeiden.In order to avoid such saturation of the anode protection tube, an arrangement for influencing an arc in mercury vapor discharge vessels is provided, in which, according to the invention, in multi-anode vessels, the individual anode protection tubes are connected to one another by permanent magnets in such a way that they are magnetic in the transverse direction are polarized. This measure is taken in that a north and south pole of a permanent magnet are attached. opposite side wall parts of the protective tube made of ferromagnetic material applied. will. Of course, the magnetic force field of the protective tube must be greater than that - which is generated by the discharge itself, in order to avoid an effective influence by an external interference field.

Die Figuren zeigen in zum. Teil schematischer Darstellung Ausführungsbeispiele der Erfindung. Die Fig. i zeigt ein. mehranadiges Gleichrichtergefäß 6 mit der Kathode 7, dem Kühldom'g und .den Anoden g. Letztere sind, vorn dem Schutzrohr io umgeben.The figures show in to. Part of a schematic representation of exemplary embodiments the invention. Fig. I shows a. multi-strand rectifier vessel 6 with the cathode 7, the cooling dome and .the anodes g. The latter are surrounded in front of the protective tube io.

Die Fig. z zeigt dieses Gefäß in Draufsicht, wobei gemäß der Erfindung zwischen den. Anodenschutzrohren die Dauermagnete i i derart angeordnet sind, daß jedes Schutzrohr auf' den gegenüberliegenden, Seiten einen Nord- bzw. Südpol aufweist.Fig. Z shows this vessel in plan view, according to the invention between. Anode protection tubes, the permanent magnets i i are arranged such that each protective tube has a north or south pole on the opposite sides.
