PURPOSE:To limit spaces among windings and a tank at a minimum, and to miniaturize the titled transformer by constituting a tap winding by two layers and each leading out tap leads in several phase only from upper and lower one sides of the tap windings. CONSTITUTION:A transformer proper in which windings 2 in each phase are wound on several leg in a three-phase three-leg core 1 and an on-load tap changer 3 are housed in the same tank 4. The windings in each phase consist of high-tension windings, low-tension windings and tap windings, and tap leads 6 are lead out of the tap windings. The tap leads are wired up to the on-load tap changer 3 from the tap windings through a space between a clamp 5 and the tank 4 formed on the side of the clamp 5. The tap leads 6a, 6b in two phases are lead out from upper sections and the tap lead 6c in one phase from a lower section at that time. Accordingly, wiring spaces can be reduced, and the tank can be miniaturized. |
