Abstract
A method of making a repairable transformer having an amorphous metal core 1 wherein three uncut legs of an annealed wound amorphous metal core are covered with an adhesive impregnated material 10 while leaving the cut leg, 6 and 7, and both adjoining radii uncovered. The adhesive is cured, causing the adhesive to bond to the core. The core joint is opened and coils 11 and 12 are placed over the legs that adjoin the cut leg. The core joint is closed and the edges of the joint and both adjoining radii are covered with a porous material. No adhesive bonds to the edges of the cut leg or to the edges of adjoining radii. The resulting transformer can be repaired by cutting away the porous material that covers the cut leg and the adjoining radii, opening the core joint, replacing a defective coil, reclosing the core joint, and resealing the cut leg as before.
