PURPOSE:To providing magnetic characteristics of a transformer by providing insulation plates on an upper and lower sides of a window of a core so as to penetrate the window to pull a yoke member of the core in the up and down direction with the upper and lower insulation plates passed through a coupling member and stretch sags of a leg member of the core. CONSTITUTION:Amorphous magnetic alloy thin belts are wound in the prescribed size to form a wound core 1 to which insulation plates 4 and 5 are arranged so as to pass through and protrude from a window of the core with their chamferred surfaces disposed toward the outside. The insulation plates 4 and 5 are connected with each other using connecting members, that is, a stud 6 and nuts 7. The nuts 7 are clamped so as to separate one insulation plate away from the other insulation plate and give tension to the wound core 1. In this state, two of the wound core 1 are joined together, each of which is set up and provided with lower and upper clamps 8 and 9 after completion of winding work of a coil 10 using bolts 11. This stretches the sags of the leg member of the core, thereby improving the magnetic characteristics of the wound core. |
