Description
Kathodenisolator für Großgleichrichter Die Erfindung betrifft eine besondere Ausbildung der Isolation zwischen dem Vakuumgefäß und dem Kathodenbehälter bei Metalldampfgroßgleichrichtern.Cathode insulator for large rectifier The invention relates to a special design of the insulation between the vacuum vessel and the cathode container for large metal vapor rectifiers.
Die bekannten Kathodenisolatoren bestehen aus Ringen aus Isoliermaterial, beispielsweise Porzellanringen. Auch sind bereits Kathodenisolatoren vorgeschlagen worden, die aus einzelnen Ringscheiben, Gummi und Eisen abwechselnd, hergestellt werden, wobei die EA isenteile durch die Guminischeiben voneinander isoliert werden. Die Porzellanisolatoren haben den Nachteil, daß sie bei Großgleichrichtern sehr hoher Leistung Ausmaße erhalten müssen, die ihre Herstellung erschweren und deren Zerstörung oder Beschädigung begünstigen.The known cathode insulators consist of rings made of insulating material, for example porcelain rings. Cathode insulators have also already been proposed made from individual ring disks, rubber and iron alternately The EA ise parts are isolated from each other by the rubber discs. The porcelain insulators have the disadvantage that they are very large in large rectifiers high performance must be given dimensions that complicate their manufacture and their Promote destruction or damage.
Erfindungsgemäß werden nun günstigere Verhältnisse fÜr die Kathodenisolatoren ceschaffen, wenn man einen aus Segmenten bestehenden, zwischen Dichtungsscheiben eingebetteten Isolier- (Porzellan-) Ring außen mit einem rinnenförmigen federnden Metallring umgibt, der gegen die Dichtungsscheiben vakuumdicht abschließt. Der Eisenkörper dient hierbei in erster Linie zur Dichtung und gegebenenfalls zur Aufnahme eines Teils der mechanischen Beanspruchungen. Die Verwendung eines federnden, den Isolierkörper teilweise umschließenden Metallringes ist bei nicht in Segmente unterteilten Kathodenisolatoren bekannt.According to the invention are now more favorable conditions for the cathode insulators create, if one consists of segments, between sealing washers embedded insulating (porcelain) ring on the outside with a channel-shaped resilient Surrounds metal ring, which seals against the sealing washers in a vacuum-tight manner. The iron body serves primarily for sealing and, if necessary, for receiving a Part of the mechanical loads. The use of a resilient, the insulating body partially enclosing metal ring is in cathode insulators that are not divided into segments known.
In der Zeichnung ist ein Ausführungsbeispiel dargestellt.An exemplary embodiment is shown in the drawing.
Die Zeichnung zeigt einen Schnitt durch den Isolator eines Großgleichrichters. Zwischen dem Vakuumgefäß i und dem Kathodenbehälter :2 liegt zwischen Gummischeiben 3 und 4 eingebettet ein aus Segmenten 5 bestehender Porzellanring, der von einem biegsamen, gegebenenfalls gegen die Dichtungsringe 3 und 4 federnden Metallringe 6 umschlossen ist. Zum Schutz des Vakuums vor Verunreinigungen durch den Gummi der Dichtungsscheiben 4 und 4 sind Vordichtungsringe 7 und 8 vorgesehen. Der aus Segmenten bestehende Porzellanring dient einerseits zur Isolation, andererseits aber auch zur Aufnahme der mechanischen Beanspruchungen zwischen den miteinander zu verbindenden Teilen des Gleichrichters, während der biegsame Metallring 6 in erster Linie als Dichtungsring dient. In die Fugen zwischen den Porzellansegmenten kann Asbest o. dgl. gebracht werden. Der Ring 6 braucht nicht unbedingt dicht an den aus Segmenten bestehenden Porzellanring anzuschließen. Die Hauptsache ist die, daß er das Vakuumgefäß dicht abschließt.The drawing shows a section through the insulator of a large rectifier. Between the vacuum vessel i and the cathode container: 2, a porcelain ring consisting of segments 5 is embedded between rubber disks 3 and 4, which is enclosed by a flexible metal ring 6 , possibly springy against the sealing rings 3 and 4. To protect the vacuum from contamination by the rubber of the sealing washers 4 and 4, pre-sealing rings 7 and 8 are provided. The porcelain ring consisting of segments serves on the one hand for insulation, but on the other hand also to absorb the mechanical stresses between the parts of the rectifier to be connected, while the flexible metal ring 6 primarily serves as a sealing ring. Asbestos or the like can be placed in the joints between the porcelain segments. The ring 6 does not necessarily need to be closely connected to the porcelain ring consisting of segments. The main thing is that it tightly seal the vacuum vessel.
