[0024] The circulating cooling member 206 includes a rectangular pipe 2061 vertically installed inside the main body 100 of the substation. A recovery pipe 2064 is provided between the upper side of the rectangular pipe 2061 and the cooling box 202, so that the cooling water flowing around can return to the cooling box 202 for recycling, energy saving and environmental protection. A water delivery pipe 2063 is provided between the lower side of the rectangular pipe 2061 and the water pump 205, so that the water in the cooling box 202 can be delivered to the rectangular pipe 2061.
