PROBLEM TO BE SOLVED: To improve a natural circulation force to increase the circulation flow rate and enhance cooling performance in an electric apparatus which is a natural circulation type and performs cooling.SOLUTION: According to an electric apparatus of an embodiment, an insulation cooling medium is naturally circulated between a body tank 3 and a cooler 11c to cool an iron core 1 and a winding 2 via two connection pipes 4, 5a and upper and lower common pipes 6, 7. This electric apparatus is formed by mounting a heat radiation panel 10c while being inclined in a vertical direction, arranging the cooler 11c in a position away from an area directly above the body tank 3, and arranging an upper header 8 upward from the upper surface of the body tank 3. |
