Abstract:
An assembly for switching electrical power comprising:a semiconductor switch arranged in a pressure-resistant vessel comprising a liquid region containing an inert liquid in order to effect a fluid cooling of the semiconductor switch during operation, the vessel further comprising a vapour region for containing a vaporized form of the inert liquid;wherein:the interior of the vessel is coupled with a cooling circuit; withat least one vapour line leading from the vapour region of the vessel to a radiator;at least one liquid line leading from the radiator to the vessel; withthe liquid line being arranged at least sectionwise within the vapour line and being extended through the vapour region of the vessel and into the interior of the vessel to such a length that its free end opens below a liquid level of the inert liquid.
