Abstract
The invention relates to an assembly for switching electrical power, wherein a semiconductor switch is arranged in a pressure-resistant vessel which is partially filled with an inert liquid in order to effect a fluid cooling of the semiconductor switch during operation, characterised in that the interior of the vessel is coupled with a cooling circuit, with at least one vapor line leading from the vessel to a radiator, and at least one liquid line leading from the radiator to the vessel, with the liquid line being arranged at least sectionwise within the vapor line and being extended from a connection point at the vessel into the interior of the vessel to such a length that its free end opens below the liquid level of the cooling liquid.
