Bei Metalldampfgleichrichtern, deren Gefäß aus Metall besteht, treten zuweilen Kurzschlüsse auf, die ihre'Erklärung darin finden, daß aus bestimmten Gründen von der jeweils inaktiven Anode ein Lichtbogen zur Kathode oder zur Gefäßwand überspringt. Um solche meistens mit unangenehmen Folgen begleiteten Kurzschlüsse zu vermeiden, wird gemäß der vorliegenden Erfindung die Anode α von einerIn metal vapor rectifiers, the vessel of which is made of metal, short circuits sometimes occur which find their explanation in the fact that for certain reasons of each inactive anode skips an arc to the cathode or to the vessel wall. To such According to the present invention the anode α of a
ίο elektrisch leitenden Schutzhülle b umgeben und diese über einen großen Widerstand r mit der Anode verbunden. Der Zweck dieser Verbindung ist, der Hülle dasselbe elektrische Potential zu verleihen, wie es die Anode selbst besitzt, und somit gefährliche dielektrische Spannungen von dieser abzuhalten. Bei einem etwa eintretenden Ausgleich zwischen der Schutzhülle b und der Kathode c kann der Strom infolge des Widerstandes r niemals schädliche Werte annehmen. Die Schutzhülle b erstreckt sich auch auf die der Kathode c zugewendete Seite der Anode a, die Ausgestaltung ist aber derart getroffen, daß der Nutzstrom in Richtung Anode — Kathode ungehindert auftreten kann (vgl. die punktierten Linien in der Figur). Die Schutzhülle /; ist an dem Isolator k befestigt und kann an dieser Stelle vollständig geschlossen sein.ίο surrounded electrically conductive protective cover b and connected to the anode via a large resistor r. The purpose of this connection is to give the envelope the same electrical potential as the anode itself, and thus to keep dangerous dielectric voltages away from it. If an equalization occurs between the protective cover b and the cathode c , the current can never assume harmful values as a result of the resistance r. The protective cover b also extends to the side of the anode a facing the cathode c , but the design is such that the useful current in the direction of the anode-cathode can occur unhindered (cf. the dotted lines in the figure). The protective cover /; is attached to the insulator k and can be completely closed at this point.
Um bei großen Gleichrichtern mit Metallgefäßen die Hindernisse zwischen der Anode a und der Gefäßwand m noch wirksamer zu gestalten, wird die innere Gefäßwand mit einer isolierenden, eingebrannten Emailleschicht e versehen. Eventuell kann auch ein passend groß gewählter Glas- oder l'orzellanzylinder die Emailleschicht ersetzen.In order to make the obstacles between the anode a and the vessel wall m even more effective in large rectifiers with metal vessels, the inner vessel wall is provided with an insulating, burned-in enamel layer e . A glass or porcelain cylinder of a suitable size can possibly replace the enamel layer.
