Abstract (de)

Die Erfindung betrifft eine Anordnung zur Abdichtung eines zylindrischen Ölgefäßes eines Schalters, vorzugsweise eines Lastwählers, Lastumschalters für Stufenschalter o.dgl., der im Kessel, insbesondere im Ölkessel, eines Transformators vorgesehen ist. Das Ölgefäß besteht aus einem Isolierrohr (1), dessen beiden Stirnflächen je ein Metallflansch (2) eines Deckel- bzw. Bodenteiles mit einer Abdichtung zugeordnet sind. Der Metallflansch (2) ist über lösbare Spannelemente, die in eine Außennut (5) des Isolierrohres eingreifen, mit dem Isolierrohr (1) verbunden. Die Außennut (5) des Isolierrohres (1) ist im Querschnitt halbkreisförmig ausgebildet. In dieser halbkreisförmigen Außennut (5) ist ein im Querschnitt runder Spannring (6) angeordnet. Im Metallflansch (2) ist mindestens eine im spitzen Winkel zur Stirnseite des Isolierrohres (1) verlaufende Gewindebohrung (7) mit einer Schraube (8) vorgesehen, wobei die Stirnfläche der Schraube (8) auf den Spannring (6) wirkt. <IMAGE>
