Abstract

1. A gas- or liquid-insulated instrument transformer comprising a head casing (1) having an opening (9) to receive at least one rod-shaped primary connection element (17), wherein, in the region of the opening (9), the casing (1) carries a flange (10) which is insulated from the primary connection element (17) by an insulating annular component and which has a sealing ring (18) on its side facing away from the casing (1), against which sealing ring (18) is pressed a disc-shaped pressure element, which has a central opening, the dimensions of which correspond to the dimensions of the primary connection element, characterised in that the disc-shaped pressure element (15) is made of an insulating material and, together with an axial extension, which extends into the opening between the casing (1) and the primary connection element (17), forms the insulating annular component ; that the disc-shaped pressure element (15) is fixed to the flange (10) by means of a plurality of screws ; and that in the region of the central opening (16), the disc-shaped pressure element (15) has at least one radial sealing ring (19).
