Abstract
PURPOSE:To prevent the drift charging phenomenon and to elevate the radiation effect of heat radiator by a method wherein a core cooling oil path and a coil cooling oil path are prepared nearly independently of each other, both cooling oil pathes are connected at the lower part and a flow rate regulating means is prepared on the way, and the lower oil pipe is connected to the coil or core cooling oil path. CONSTITUTION:A coil cooling oil path A flowing from a common oil path 5, 5 in the lower part of a core 1 to the upper part of inside of case passing oil path gaps in a coil 15 and a core cooling oil path 13 flowing from a concavely sunken part 2b to the upper part of inside of case passing the surface and the interior of the core, form pathes connected in parallel to a cooler 28. Cooling oil fed by an oil pump 30 is separated into the pathes A, B, joined when they reached at the upper part of inside of the case and returns to the cooler 28 through an upper oil pipe 31. The flowing speed of the insulating oil in the pathes A, B can be regulated optionally by controlling the quantity of insulating oil flowing in the path B with an oil regulating valve Va.
