<p><P>PROBLEM TO BE SOLVED: To provide a simple replacement method that reduces the suspension period of electrical substation equipment as much as possible in the event of replacement of a cooling system for an object to be cooled installed in an underground substation. <P>SOLUTION: The method for replacement of a cooling system for electrical substation equipment of an underground substation includes: a step for installing additional temporary cooling facilities 30 in the cooling system 10 for electrical substation equipment of an underground substation which is provided with cooling facilities 20 for cooling the electrical substation equipment of the underground substation; a step for setting up connection points 57, 58 for changing the facilities for cooling the substation equipment between the cooling facilities 20 and the temporary cooling facilities 30; a step for shifting the facilities for cooling the electrical substation equipment to the temporary cooling facilities 30 from the cooling facilities 20 by switching between the connection points 57 and 58; a step for removing and replacing the cooling facilities 20 with new cooling facilities 20 while the temporary cooling facilities 30 continues to cool the electrical substation equipment; and a step for shifting the facilities for cooling the electrical substation equipment to the newly installed cooling facilities 20 from the cooling facilities 30 by switching between the connection points 57 and 58. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
