COOLING SYSTEM FOR OFFSHORE WIND POWER GENERATION FACILITY SUBMARINE CABLE

摘要

PROBLEM TO BE SOLVED: To provide a cooling system for an offshore wind power generation facility submarine cable, capable of suppressing a rise of temperature of the submarine cable.SOLUTION: A submarine cable 1 is connected to an offshore wind power generation facility 20. The submarine cable 1 is inserted into a protective pipe fixed on the offshore facility, and is connected to the offshore wind power generation facility 20 in the air. The submarine cable 1 is connected to another offshore facility, an electric power substation on the ground, etc. and transmits electricity obtained by wind power generation. The protective pipe 3 is provided outside the offshore wind power generation facility 20. On the offshore wind power generation facility 20 is provided a cooling device 10. The cooling device 10 is composed of a pump 5 and an injection pipe 7. The cooling device 10 is a device for cooling the protective pipe 3 and the submarine cable 1. The injection pipe 7 is connected to the pump 5. The pump 5 takes sea water by using a water-intake pipe submerged under the sea, and discharges sea water to the protective pipe 3 through the injection pipe 7. A monitor device 21 measures or estimates a temperature of the submarine cable.SELECTED DRAWING: Figure 1
