Abstract
In a sealing device () for sealing the through hole of an electrode, the pressurizing medium that generates the pressure of mechanical sealings against a rod electrode structure is an inert gas, such as nitrogen. The means for pressing the created sealing ring () against the rod electrode structure () include a gas distribution chamber () surrounding the sealing ring (); a first channel () that is arranged to provide a flow path for the inert gas in between the hose () and the gas distribution chamber (); an annular groove () in the sealing surface () of the sealing ring (); and a second channel (), which is placed in the sealing ring () and is arranged to provide a flow path for the gas from the gas distribution chamber to the groove () for extruding the gas in between the sealing surface () and the rod electrode structure ().
