Abstract
The utility model discloses a positioning device for a transformer coil. The positioning device comprises a coil mold, a coil inner row and an inner row positioning part, wherein the coil inner row is flatly attached onto one plane end of the coil mold, and an inner row milling positioning groove is arranged at the upper end of the coil inner row. The inner row positioning part is of a right-angle bending structure, one end of the inner row positioning part is provided with a convex block corresponding to the inner row milling positioning groove, and the other end of the inner row positioning part is provided with a bolt hole. The inner row positioning part clamps the coil inner row at the plane end of the coil mold and then is fixedly connected with the coil mold through a bolt. Therefore, the positioning device for the transformer coil ensures that the wound transformer coil is attractive in appearance and good in tightness, electric performance and mechanical strength.
Description
Technical field
The utility model relates to the field of transformer, particularly relates to a kind of positioner for winded coil of transformer.
Background technology
When the coil of coiling transformer, usually to use row in the coil, row is the skeleton of transformer coil in the coil, in order to guarantee transformer long-term safety reliability service, must satisfy the basic demand of the aspects such as electrical strength, high-temperature capability and mechanical strength.Row's effect is in the coil: one, as vertical oil duct of coil; Two, play the effect of fixing and set winding; Three, play the effect of support coils line segment.
Usually when the coil of coiling transformer, coil die is provided with interior file leader section positioning convex strip, be used for row in the fixed coil, but since in the coil row's one side be close to interior file leader section positioning convex strip, when winded coil of transformer, the coil convex epirelief easily appears, moulding is not attractive in appearance, and because opposite side is not fixed, loosening phenomenon is arranged when coiling, cause the transformer coil of coiling not tight, thereby affect its electrical strength and mechanical strength.
The utility model content
The technical problem that the utility model mainly solves provides a kind of used in transformer coil positioner, has guaranteed the transformer coil good looking appearance of coiling, and compactness is good, has good electric and mechanical strength.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of transformer foil around the low-voltage coil positioner, comprise coil die, row and interior registration part in the coil, row is smooth in a flat end of coil die in the described coil, row's upper end is provided with an interior gang milling location notch in the described coil, described interior registration part is the structure of right angle bending, one end of described interior registration part is provided with the projection corresponding with interior gang milling location notch, the other end is provided with bolt hole, then described interior registration part is fixedly connected with by bolt the flat end that row in the coil is stuck in coil die with coil die.
In preferred embodiment of the utility model, described coil die is oval cylindrical shell.
In preferred embodiment of the utility model, row is the strip structure in the described coil.
In preferred embodiment of the utility model, described coil die is provided with the bolt hole corresponding with the bolt hole on the interior registration part.
The beneficial effects of the utility model are: used in transformer coil positioner of the present utility model, during the coil of coiling transformer, row in the coil is stuck in the flat end of coil die with interior registration part, then be fixedly connected with coil die by bolt, after coiling is finished, take out interior registration part and coil die, guaranteed the transformer coil good looking appearance of coiling by this used in transformer coil positioner, and compactness is good, has good electric and mechanical strength.
