Description

Großgleichrichter für hohe Stromstärken Gegenstand des Hauptpatents 452 709 ist ein Großgleichrichter von hoher Leistungsfähigkeit, bei welchem an Stelle einer einzigen Kathode zwei oder mehrere räumlich voneinander getrennte, jedoch elektrisch untereinander kurzgeschlossene Teilkathoden vorgesehen sind, denen je eine besondere Zünd-und Erregervorrichtung zugeordnet ist. Eine hinsichtlich der Raumausnutzung des Vakuumgefäßes, der Kühlung und der Gleichförmigkeit des Betriebes eines solchen Gleichrichters sehr günstige Bauart erzielt man nun, wenn erfindungsgemäß die Anoden zwischen einem äußeren und einem dazu konzentrischen inneren Kranz von @ Teilkathoden angeordnet werden.Large rectifier for high currents The subject of the main patent 452 709 is a large rectifier of high performance, in which instead of a single cathode two or more spatially separated but electrically short-circuited partial cathodes are provided, each of which is assigned a special ignition and excitation device. A very favorable design with regard to the space utilization of the vacuum vessel, the cooling and the uniformity of the operation of such a rectifier is achieved if, according to the invention, the anodes are arranged between an outer and an inner ring of partial cathodes concentric to it.

Man erhält damit eine vorteilhaftere Gleichrichterbauart als bei der bekannten, ebenfalls Teilkathoden aufweisenden Anordnung, bei der jede Teilkathode selbst einen geschlossenen Ring oder -einen Teilring bildet und diesen zueinander konzentrischen Ringkathoden ebenfalls ringförnvge Ano,d'en gegenüberstehen. Der Vorteil der neuen Bauart liegt hauptsächlich darin, daß der an den Teilkathoden entwickelte Quecksilberdampf von den Anodenräumen ferngehalten und, damit die Betriebssicherheit durch Verhütung von Rückzündungen und Kurzschlüssen erhöht wird..This gives a more advantageous type of rectifier than that of the known, also having partial cathodes arrangement, in which each partial cathode itself forms a closed ring or a partial ring and these to one another concentric ring cathodes are also ringförnvge Ano, d'en opposite. Of the The main advantage of the new design is that the partial cathode developed mercury vapor is kept away from the anode compartments and thus the operational safety is increased by preventing reignition and short circuits ..

Als Ausführungsbeispiel der Erfindung ist auf der Zeichnung ein solcher Großgleichrichter in Achsenschnitt schematisch dargestellt. Einige Teilkathoden k1 bilden einen Kranz, der verhältnismäßig nahe der Gefäßachse liegt, während die übrigen Teilkathoden k. in einem dem Umfang des Gefäßes benachbarten Kranze angeordnet sind. Die Anoden u bilden einen Kreis, der etwa bis zur Mitte des zwischen beiden Kathodenkränzen liegenden Raumes reicht. Gegen die Quecksilberdämpfe sind die Anoden in an sich bekannter Weise durch Blechmäntel ml, m2 geschützt, die bei dem . dargestellten Ausführungsbeispiel doppelwandig sind, um ein Kühlmittel, vorzugsweise strömendes Wasser, aufnehmen zu können.As an embodiment of the invention, such a large rectifier is shown schematically in axial section in the drawing. Some partial cathodes k1 form a ring which is relatively close to the vessel axis, while the remaining partial cathodes k. are arranged in a rim adjacent to the circumference of the vessel. The anodes u form a circle that extends approximately to the middle of the space between the two cathode rings. The anodes are protected against the mercury vapors in a manner known per se by sheet metal jackets ml, m2, which in the case of the. illustrated embodiment are double-walled in order to be able to accommodate a coolant, preferably flowing water.
