Rotating joint of high or medium voltage, and the construction outside of Costa

摘要

Rotating joint of high or medium voltage, and, building off the coast, the invention relates to a rotating joint of high voltage.Including an annular external element defining a cylindrical chamber around a longitudinal axis and an internal cylindrical element coaxial with the external element and rotatable on said featuresTo externally around said longitudinal axis.The internal and external elements each include at least two axially spaced electrical conductors, which conductors are rotating with the internal and external elements.The conductors forming at least two pairs placed with contact surfaces in mutual electrical contact.A conductor in each pair is provided in the internal element.The other in the external element and being connected to a voltage line that extends to a respective input terminal and an output terminal respectively.The conductors being surrounded by an insulating material.The invention is characterized by the fact that the electrical conductors of the external element are provided in a recess in a ring external insulating solid annular,The electrical conductors of the internal element are provided in a recess in a ring insulating solid internal annular coaxial with the outer ring.The internal and external insulating rings each defining a surface extending in an axial direction limit, the limit surfaces of rings being placed in close proximity.The electrical conductors being placed with their contact surfaces at or near the surface of the limit.
