Cooling system with deionised water for electrical equipment

摘要

The system has a main circuit (4) for directing and cooling deionized water to be circulated in an electrical equipment (3). A main pumping group (6) circulates the de-ionized water in the circuit. A main power source supplies power to the group. A deionization circuit (5) is connected to points of the circuit for de-ionizing water of the main circuit. The deionization circuit has a deionizer (15). A secondary pumping group (7) circulates de-ionized water in the deionizer. Secondary power source supplies power to the secondary pumping group, and is less powerful than the main power source. Independent claims are also included for the following: (1) an underwater electric installation (2) a method for cooling an electric installation.
