Abstract: The present invention relates to an electrical device (1) comprising a gas-insulated transformer (101) or reactor. The electrical device (1) comprises a housing (12) enclosing an interior space (14), at least a portion of which defining an insulation space (16) containing a dielectric insulation fluid comprising an organofluorine compound, and an electrical component (18) being arranged in the insulation space (16) and being surrounded by the insulation fluid. The electrical component (18) comprises at least one winding (20, 22). The electrical device (1) further comprises an electrical connector (32) for bringing the apparatus (10) from non- operational state to operational state by connecting at least one winding (20, 22) to a power grid. The device (1) further comprises an auxiliary power source (34) which is connectable to at least one winding (20, 22) when the apparatus (10) is in the non-operational state.

Abstract: The present invention relates to gas-insulated electrical apparatuses (10), in particular gas-insulated transformers (101) or reactors, comprising a housing (12) enclosing an interior space (14), in which an electrical component (16) comprising a winding (18, 20) is arranged, at least a portion of the interior space (14) defining an insulation space (24) which is filled with an insulation fluid (26) electrically insulating at least a part of the electrical component (16) from the housing (12). According to the invention, the electrical apparatus (10; 101) further comprises a cooling element (28) comprising a condenser (36), an evaporator (30) and a cooling fluid (32) to be circulated between the condenser (36) and the evaporator (30). The evaporator (30) is designed such that at least a part of the electrical component (16) is immersed in the cooling fluid (32) in its liquid state, thus being in direct contact with the cooling fluid (32).
