[0003] Usually, when winding the coil of a transformer, the coil mold is provided with inner row head positioning protrusions to fix the inner row of coils. When the transformer coil is used, it is easy to have coil bumps, the shape is not beautiful, and because the other side is not fixed, there is a phenomenon of looseness during winding, resulting in the winding of the transformer coil is not tight, thus affecting its electrical strength and mechanical strength

The invention discloses a positioning device for a foil wound low voltage coil of a transformer. The device comprises a coil mold, a coil internal flat cable and an internal flat cable positioning element; the coil internal flat cable is flatly adhered to a plane end part of the coil mold; an internal flat cable milling positioning groove is arranged at the upper end of the coil internal flat cable; the internal flat cable positioning element is in a right angle bending structure; one end of the internal flat cable positioning element is provided with a bump corresponding to the internal flat cable milling positioning groove; a bolt hole is arranged at the other end of the internal flat cable positioning element; the coil internal flat cable is clamped at the plane end part of the coil mold by the internal flat cable positioning element and is fixedly connected with the coil mold by bolts. With the adoption of the positioning device provided by the invention, the appearance of the wound transformer coil is attractive, the compactness is good, and both the electric and mechanical strengths are good.
Description
technical field [0001] The invention relates to the field of transformers, in particular to a positioning device for winding transformer coils. Background technique [0002] When winding the coil of a transformer, the inner row of the coil is usually used. The inner row of the coil is the skeleton of the transformer coil. In order to ensure the long-term safe and reliable operation of the transformer, the basic requirements of electrical strength, heat resistance strength and mechanical strength must be met. The functions of the coil inner row are: first, as the longitudinal oil channel of the coil; second, to fix and position the coil; third, to support the coil line segment. [0003] Usually, when winding the coil of a transformer, the coil mold is provided with inner row head positioning protrusions to fix the inner row of coils. When the transformer coil is used, it is easy to have coil bumps, the shape is not beautiful, and because the other side is not fixed, there is...
