Above-mentioned blower fan is centrifugal fan, and above-mentioned water-cooling air cooler carries out heat exchange by cooling water and the hot-air that enters in the water-cooling air cooler, and the heat in the hot-air is taken away by cooling water.
Aforementioned barriers is rectangular-shaped insulation board, have three dividing plate high-tension coil mounting holes at dividing plate, three high-tension coils are installed on respectively in above-mentioned three dividing plate high-tension coil mounting holes, and aforementioned barriers is shelved on the supported diaphragm angle steel that is installed on the transformer shell inwall.
This water-cooled three-phase power transformer is simple in structure, easy for installation with the directed circulating device of wind direction, and radiating effect is remarkable, can guarantee that three-phase power transformer is under the normal air temperature to move.
