The lid esfu00c9rica lines exit of high voltage in transformer u00e0leo

摘要

Invention patent: cover esfu00c9rica lines exit of high voltage in u00e0leo transformers.The present invention relates to a spherical cap (10) for a line of high output voltage, comprising an electrically conductive element (12 + 14), (62 + 64 + 66)), which is prepared cilindricamente hollow around a rotational axis (20.70) and merges into a the hemispherical form (14.6 4) at its first axial end (16).A provision is made for a connection device (22 + 24), (74 and 76), (100th, (b)), which has a passage opening (116) and which serves to electrically and mechanically connect the element (12 + 14), (62 + 64 + 66), a tube. Shielded electrical (26,72), which comprises at least two barriers of isol Budget (30 + 34 + 38) (32 + 36 + 40)) which are spaced from one another.Respectively adapted to the form of the hollow cylindrical element (12 + 14), (62 + 64 + 66)), and involves the u00fatlimo to a respective first and second distances. The barriers of isolation (30 + 34 + 38) (32 + 36 + 40) respectively have a connector fixing tube (30,32) to drive through a tube shielding (26,72) to the connection device (22 + 24), (74 + 76), (100th. (b)).The first barrier insulation (30 + 34 + 38) is spaced from the second barrier insulation (32 + 36 + 40) by at least one ring of insulation (42,44,46,50) which is arranged around the rotational axis (20.70) and which has a corrugated shape radially shaped (54,56), preferably achat ADA.
