Center column spliced iron core structure of extra-high voltage transformer

The invention relates to a central column spliced iron core structure of an extra-high voltage transformer, which is characterized in that 1, 3 and 5 and 2, 4 and 6 joint units of a central column iron core unit are respectively spliced by a left side isosceles trapezoid sheet and a right side isosceles trapezoid small-angle-removed sheet as well as a left side isosceles trapezoid small-angle-removed sheet and a right side isosceles trapezoid sheet, and two sides of the central column iron core unit are spliced into V-shaped sharp corners; a left iron core unit and a right iron core unit are arranged on the two sides of the center column iron core unit respectively, an upper left iron core unit, an upper right iron core unit, a lower left iron core unit and a lower right iron core unit are arranged on the upper side and the lower side of the center column iron core unit respectively, and V-shaped connectors are formed in the connecting positions of the upper left iron core unit, the upper right iron core unit
