Abstract
A high voltage system including a HVDC valve, a liquid fluid cooling system for cooling the valve, and a high voltage bushing for transferring high voltage and high current from the fluid cooled HVDC valve. The high voltage bushing includes an insulating body surrounding an electrical conductor electrically connectable to a connector of the HVDC valve. The electrical conductor of the high voltage bushing includes a cooling duct arranged for cooling the bushing utilizing a circulating gaseous fluid. A heat exchanger is connected to the cooling duct and adapted to cool the circulating gaseous fluid, wherein the heat exchanger is connected to the cooling system of the HVDC valve and adapted to receive cooling water from and to return heated cooling water to the cooling system of the HVDC valve.
