Abstract (en)
[origin: EP0103299A1] 1. Cylindrical oil vessel, for tap switches of tapped transformers, which consists of an insulating cylinder (1) carrying the outer terminal and output contacts (7, 13) and of a cover and base part (2) flanged on thereat, wherein the base part (2) engages by a rim into the clear width of the insulating cylinder (1) and an O-ring seal (5), which is arranged at this rim in an encircling recess (4), lies sealingly against the inside of the insulating cylinder (1) and wherein at least one output ring (6) is present, which extends around at the inside wall fo the insulating cylinder (1) and is connected with the outer output contacts (7), characterized thereby, that the base part (2) is constructed as glass-fiber re-inforced moulded part of insulating material, which part lies against the end face of the insulating cylinder by means of several shaped-on eyelets (9) protruding relative to the outer circumference of the insulating cylinder (1) and is firmly connected with the insulating cylinder by means of several tie bolts (8), which are on the one hand plugged through the eyelets and on the other hand anchored at the output contacts (7) sitting in the wall of the insulating cylinder, wherein the rim (3) engaging into the insulating cylinder reaches almost as far as the output ring (6) and the upwardly free recess (4) for the O-ring seal (5) is covered by means of the output ring.
