Abstract
The invention relates an abnormal-shaped wire for a transformer and a production method of the abnormal-shaped wire, and belongs to the technical field of transformer winding wires. According to the technical scheme, the cross section of the abnormal-shaped wire is of a rectangular structure, at least one upper corner of the rectangular structure is an arc (3), the short edges of the rectangular structure are replaced with the arcs (3), and the arcs (3) is started from lower corners of the short edges of the rectangular structure, are tangent with the long edges (2) of the rectangular structure, and are in smooth connection with the long edges (2). Other corners of the rectangular structure are provided with chamfers (4), the scope of the radii of the chamfers (4) is 0.5-1.0mm, and the arcs are started from the lower corners of the short edges of the rectangular structure, are tangent with the long edges (2) of the rectangular structure, and are in smooth connection with the long edges (2). According to the abnormal-shaped wire and the production method, on the basis of the rectangular cross section, two lower corners are kept unchanged, and it is guaranteed that the abnormal-shaped wire can serve as a transformer winding wire for normal use. Two upper corners of the rectangular structure are changed to be the arcs, the short edges of the rectangular structure are replaced with the arcs of the upper corners respectively, the arcs are tangent with the long edges of the rectangular structure and are in smooth connection with the long edges (2), and therefore the point electric discharge phenomenon when the wire is used in the transformer can be greatly reduced.
