Description

Kathodenisolator für Großgleichrichter Die Erfindung betrifft eine besondere Ausbildung der Isolation zwischen dem Vakuumgefäß und dem Kathodenbehälter bei Metalldainpfgroßgleichrichbern, d. h. :eine besondere Ausbildung des sogenannten Kathodenisolators.Cathode insulator for large rectifier The invention relates to a special design of the insulation between the vacuum vessel and the cathode container in the case of Metalldainpf large rectifiers, d. H. : a special training of the so-called Cathode insulator.

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 Eisenteile durch die Gummischeiben 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 iron parts are isolated from each other by the rubber washers. 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 geschaffen, 1v enn man den aus Isolierstoff (Porzellan o. dgl.) bestehenden Ring aus einzelnen Segmenten zusammensetzt und diese durch Lötdichtungen vakuumdicht miteinander verbindet. Die Fugen zwischen den Segmenten können mit Asbest o. dgl. ausgefüllt werden.According to the invention, the conditions for the cathode insulators are now more favorable created by using the ring made of insulating material (porcelain or the like) composed of individual segments and these vacuum-tight by means of soldered seals connects with each other. The joints between the segments can with asbestos or the like. fill out.

In der Zeichnung ist ein Ausführungsheispiel dargestellt. Abb. i zeigt einen Querschnitt durch den Isolator eines Großgleichrichters, Abb. z eine Draufsicht, Abb. 3 eine Draufsicht auf eine andere Ausführungsform.An exemplary embodiment is shown in the drawing. Fig.i shows a cross section through the insulator of a large rectifier, Fig.z a plan view, Fig. 3 is a plan view of another embodiment.

Zwischen Vakuumgefäß i und Kathodenbehälter z liegt zwischen Dichtungsringen 3 und q. eingebettet ein aus Segmenten 5 zusammengesetzter Porzellanring. Die Fugen zwischen den Porzellansegmenten werden mit Asbest ausgefüllt, und die Segmente werden an der Außenseite durch Lötdichtungen 6 vakuumdicht miteinander verbunden. Die Porzellansegmente können mittels kleiner Stege oder überlappungen übereinandergYeifen. Sich überlappende Segmente sind in Abb.3 dargestellt. Zum Schutz des Vakuums gegen Verunreinigungen aus den Dichtungsgummiringen 3 und q. können in. an sich bekannter Weise Vor dichtungsringe 7 verwendet werden.Between the vacuum vessel i and the cathode vessel z lies between sealing rings 3 and q. embedded a porcelain ring composed of segments 5. The joint between the porcelain segments are filled with asbestos, and the segments are connected to one another in a vacuum-tight manner on the outside by soldered seals 6. The porcelain segments can overlap by means of small bars or overlaps. Overlapping Segments are shown in Figure 3. To protect the vacuum against contamination from the rubber seals 3 and q. can in a known manner in front of sealing rings 7 can be used.
