<p>PURPOSE:To reduce the size of the three-phase transformer in transportation by so constructing the transformer that oil ducts between unit single-phase transformers and unit three-phase transformers are removed so that the respective unit single- phase and three-phase transformers and the oil ducts may be individually divided. CONSTITUTION:When the transformer is transported, the unit single-phase transformers 1, 2, 3, and the unit three-phase transformers 16 with the oil ducts 8a, 8b, are removed and transported individually. The oil ducts 8a, 8b are again mounted in the field, and the respective unit single-phase and three-phase transformers 1, 2, 3, and 16 are connected therebetween to construct the on-load tap changing three- phase transformer having initial rated specifications.</p> |
