Abstract
PURPOSE: To miniaturize and lighten the whole body, by forming the three-phase three-winding transformer by two tanks, and by housing high-voltage winding at the line end sides and medium-voltage winding wound on cores in one tanks and high-voltage winding at the neutral point sides, medium-voltage winding and low- voltage winding similarly wound on cores in the other tanks.
CONSTITUTION: This three-phase three-winding transformer is constituted by two tanks 151, 152, and winding portions 11 at the line sides of high-voltage winding and medium-voltage winding 21 and housed in one tanks 151 in shapes that are wound on cores 41. Winding portions 12 at the neutral point sides of high-volgate winding, medium-voltage winding 22 and low-voltage winding 3 are housed in the other tanks 152 in shapes that are wound on cores 42. The high-voltage winding portions 11, 12 are let pass into oil-filled ducts 61 connecting the two tanks and connected in series, and the medium-voltage winding 21, 22 are also connected in parallel through ducts 62. Thus, a single-phase transformer is formed by the two tanks 151, 152, and three-phase connection is connected through the insides of ducts 71W73. Consequently, the transportation of the transformer of 500KV class capacity is made remarkably advantageous.
