PURPOSE:To uniformalize the temperature of oil enclosed into a plurality of electric apparatus by a method wherein oil pipings are drawn from the upper sections of the oil-filled electric apparatus, and connected to the oil inlet sides of coolers mounted in response to the other oil-filled electric apparatus. CONSTITUTION:Oil which cools an oil-filled electric apparatus 10, takes heat and is heated flows into a cooler 16 mounted at the apparatus 12 side, heat is exchanged here, and the oil is cooled and flows into a lower section of the apparatus 12. The oil cools the apparatus 12, takes heat and is heated again, flows into a cooler 14 installed to the apparatus 10 through an oil piping 20 from an upper section of the apparatus 12 and is cooled, and flows into a lower section of the apparatus 10 through an oil piping 22. |
