Abstract

PURPOSE:To reduce the quantity of feeding oil without harming the cooling ability of a cooler and to prevent the generation of static discharge to be caused by the oil flow by a method wherein lower pipings of the cooler are connected to a common oil path, and orifices, etc., are provided to side pipes diverging from the common oil path. CONSTITUTION:Plural cooling devices providing with the cooler 1 and an oil pump 2 are arranged at the outside of the tank 4 are connected to the upper parts and the lower parts of the tank 4 respectively through the upper and the lower pipings 13, 18, and the respective lower pipings 13 are connected in common with the common oil path 11. The plural side pipes 12 diverging from the common oil path 11 are arranged along the side wall of the tank 4, one end of them are connected to the upper parts of the side wall of the tank and a flow control valve or the orifice is provided on the halfway of each side pipe 12. By this way, the quantity of feeding oil to the main body of transformer is reduced without harming the cooling ability of the cooler to reduce the damage of insulators, and the generation of static discharge to be caused by the oil flow can be prevented to the utmost.
