Control method for a liquid-cooled cable installation with a hollow conductor, through which a coolant flows, as the cable conductor. The hollow space is divided in the longitudinal direction by partitions forming separate canals for the outgoing flow and the return of the coolant and in which canals the coolant is in contact with the conductor at high-voltage potential. Heat exchangers are provided at the start and the end of the cable system or at intermediate stations. The cable flow temperature ( theta Z*) of the coolant is lowered with increasing load of the cable by influencing the heat exchanger and is conversely raised with falling load in such a manner that the mean value of the coolant ( theta m) remains constant. |
