Abstract

Zwangsgekühlter Drahtwiderstände, bei denen die Verlust­ leistungen mittels Siede- oder Flüssigkeitskühlung abge­ führt werden, werden bei Stromrichtern verwendet, bei denen die Kühlung der Halbleiterelemente mittels Dosen­ kühlung erfolgt. Die Beschaltungswiderstände werden an den Seitenflächen der Kühldosen angeordnet. Hierbei gibt es eine Leistungsbegrenzung, die von der Seitenflächen­ größe der Kühldose und der zulässigen Flächenbelastung des Widerstandsmoduls abhängig ist. Eine Widerstandsbau­ art mit Zwangskühlung, bei dem mit kleinem Temperatur­ gradient größere Leistungen abgeführt werden können, wird dadurch erreicht, daß ein Widerstand aus einem elektrisch isolierenden zylindrischen Hohlkörper (1) be­ steht, auf dessen Innenwand eine Widerstandsdrahtwick­ lung (6) angeordnet ist und ein Kühlmedium das Innere durch­ fließt. An beiden Seiten ist ein elektrischer Anschluß (13, 19) vorgesehen; auf der einen Seiten an einem Kragen (16) und auf der anderen Seite entweder an einem Kragen oder an einem Deckel (9). Der Kragen dient gleichzeitig zum Anschluß einer hydraulischen Leitung für das Kühlmedium. Bei einseiti­ gen Anschluß strömt das Kühlmedium in der Mitte nach unten und steigt an den Seiten nach oben und kühlt gleichzeitig die Drahtwindungen. Bei beidseitigem An­ schluß durchströmt das Kühlmedium in einer Richtung das Innere des Widerstandes. Forced-cooled wire resistors where the loss services by means of boiling or liquid cooling are used in power converters which the cooling of the semiconductor elements by means of cans cooling takes place. The wiring resistances are on the side surfaces of the cooling boxes arranged. Here there there is a power limitation from the side faces size of the cooling box and the permissible area load of the resistance module is dependent. A resistance building type with forced cooling, at the low temperature gradient larger services can be performed, is achieved in that a resistance from a electrically insulating cylindrical hollow body (1) be stands, on the inner wall of a resistance wire lung (6) is arranged and a cooling medium through the interior flows. There is an electrical connection on both sides (13, 19) intended; on one side on a collar (16) and on on the other side either on a collar or on one Cover (9). The collar also serves to connect one hydraulic line for the cooling medium. At Einseiti The cooling medium flows in the middle towards the connection below and rises on the sides and cools at the same time the wire turns. With bilateral connection finally flows through the cooling medium in one direction Inside of the resistance.
