The invention relates to an electric shielding arrangement (1) of a disconnection point of a conduit for an HVDC component, in particular an HVDC transformer or an HVDC choke. The shielding arrangement (1) consists of two outer tubular electrodes (10, 20) and an inner tube (30) in the interior of the two outer tubular electrodes (10, 20), said inner tube bridging the gap (50) at the disconnection point between the two outer tubular electrodes (10, 20). The electric fields are conducted across the disconnection point through said inner tube (30). Lower maximal direct current field strengths are thereby produced than without said inner tube (30). The substantially tubular geometry of the two outer tubular electrodes (10, 20) and of the inner tube (30) ensures a simple and inexpensive producibility. Furthermore, a large tolerance can be ensured with respect to the sections to be connected relative to each other because larger gaps are also bridged by the inner tube (30). |
