ABSTRACT:
This electrical connection relates to an electrical link between a device in a metallic sheath insulated by a gas under pressure and a transformer insulated by a dielectric liquid. The connection comprises a jacket separating the interior volume of the transformer from that of the device and having a frustoconical insulating wall shielding the capacitor bushing and penetrating into the sheath. The insulating wall comprises on the outside of its base a flange having two concentric annular surfaces, one coming into contact with the sheath of the device and defining a junction plane between the interior volume of the device under gas pressure and the atmosphere, the other defining with another part a junction plane between the interior volume of the jacket filled with dielectric liquid and the atmosphere.
