Description
Es sind Trockengleichrichter bekannt, bei denen mehrere elektrisch in Reihe geschaltete Gleichrichtereinheiten unter Zwischenlage von Metallfolie zwischen der Oxydschicht einer Einheit und dem Grundmetall der nächstfolgenden Einheit auf einem Schraubenbolzen angeordnet und zwecks guten elektrischen Kontaktes zwischen Metallfolie und Oxydschicht unter starkem Druck gegeneinander-There are known dry rectifiers in which several electrically connected in series Rectifier units with the interposition of metal foil between the oxide layer of a Unit and the base metal of the next unit on a screw bolt arranged and for the purpose of good electrical contact between the metal foil and the oxide layer under strong pressure against each other-
to gepreßt werden. Es ist auch vorgeschlagen worden, bei derartig angeordneten und in Reihe geschalteten Gleichrichtereinheiten die zwischengelegte Metallfolie durch eine unmittelbar auf die Metalloxydschicht aufgespritzte Schicht eines geeigneten Metalles zu ersetzen. Diese Maßregel gestattet, mit sehr dünner metallischer Zwischenschicht auszukommen, und hat daher besonders bei Gleichrichtern, die aus vielen gleichartigen Einheiten zusammengesetzt sind, eine gewisse Verringerung der Baulänge zur Folge. Die Nachteile dagegen, die mit der Anwendung eines kräftigen ■Anpressungsdruckes verbunden sind (z. B. ungünstige Wärmeabführungsverhältnisse, Durchschlagsgefahr des ganzen Gleichrichters bei lokaler Überlastung einzelner Einheiten), lassen sich mit der bekannten Anordnung keineswegs vermeiden.to be pressed. It has also been proposed, in rectifier units arranged in this way and connected in series, to replace the intermediate metal foil with a layer of a suitable metal sprayed directly onto the metal oxide layer. This rule makes it possible to get by with a very thin metallic intermediate layer and therefore results in a certain reduction in the overall length, especially in the case of rectifiers that are composed of many similar units. On the other hand, the disadvantages associated with the application of strong contact pressure (e.g. unfavorable heat dissipation conditions, risk of breakdown of the entire rectifier in the event of local overloading of individual units) cannot be avoided with the known arrangement.
Den Gegenstand der Erfindung bildet eine Einrichtung, bei der die vorstehend angegebenen Nachteile völlig vermieden sind. Die Erfindung beruht auf der Erkenntnis, daß, wenn man die zur Stromzu- oder -abführung erforderlichen Stromleiter auf irgendeine andere Weise mit dem Grundmetall einerseits und dem Spritzmetallüberzug andererseits leitend verbindet, ein Aneinanderpressen der benachbarten Gleichrichtereinheiten überhaupt nicht erforderlich ist. Diese können daher in beliebigem Abstand voneinander angeordnet werden und vertragen infolgedessen eine wesentlich höhere Strombelastung.The subject of the invention is a device in which the above Disadvantages are completely avoided. The invention is based on the knowledge that when you use the current supply or discharge required current conductor in some other way with the base metal on the one hand and the spray metal coating on the other hand conductively connects, pressing the neighboring rectifier units is not required at all. These can therefore be used in can be arranged at any distance from each other and, as a result, tolerate a substantial higher current load.
Von besonderem Vorteil erweist sich die Einrichtung gemäß der Erfindung, wenn man, wie es an sich bekannt ist, die einzelnen Platten beiderseits oxydiert und mit einem auf der Oxydschicht angebrachten Metallüberzug versieht. Man kann dann ohne Material- bzw. Gewichtserhöhung die an sich schon hohen Leistungsfähigkeiten des Trokkenplattengleichrichters verdoppeln.The device according to the invention proves to be particularly advantageous if one as it is known per se, the individual plates are oxidized on both sides and with one metal coating applied to the oxide layer. You can then without material or increase in weight, the already high performance capabilities of the dry plate rectifier double.
