PURPOSE:To facilitate the uprising of lead wires, while to avoid enlargement of height thereof in core windows when the three core leg parts and the york parts to constitute a core type three phase transformer are to be tightened using clamping metal fittings and magnetic clamps by a method wherein breadth of the clamp is narrowed at the parts positioning between the respective core legs in the magnetic clamps. CONSTITUTION:Windings 1 are wound around the outside circumference of the three core leg parts 4 corresponding to the respective phases of the core type three phase transformer, and the yoke parts 5 provided at both the ends of the leg parts 4 and the leg parts 4 are tightened to be integrated in one body using the clamping metal fittings not shown in the figure. Moreover the magnetic clamps are arranged being accumulated on the clamping metal fittings to be tightened also, while at this time, the magnetic clamp is constituted of the first and the second clamps. Namely, the first clamp 11 is made to have breadth the same with the clamping metal fittings, while the calmp thereof is arranged so to extend over another phase at the outside of core window, and the second clamp 12 is provided protruding outside of the leg part 4 coming in contact with the clamp 11. Accordingly space for leading out of the lead wires 10 is provided between the leg parts 4. |
