Abstract
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
The present invention relates to the field of transformer, particularly relate to a kind of positioner for winded coil of transformer.
Background technology
When the coil of coiling transformer, conventionally to use row in coil, in coil, row is the skeleton of transformer coil, in order to guarantee transformer long-term safety reliability service, must meet the basic demand of the aspects such as electrical strength, high-temperature capability and mechanical strength.Row's effect is in coil: one, as longitudinal oil duct of coil; Two, play the effect of fixing and set winding; Three, play the effect of support coils line segment.
Conventionally when the coil of coiling transformer, coil die is provided with interior file leader portion positioning convex strip, for row in fixed coil, but be close to interior file leader portion positioning convex strip owing to arranging a side in coil, when winded coil of transformer, easily there is coil convex epirelief, moulding is not attractive in appearance, and because opposite side is not fixed, has loosening phenomenon when coiling, cause the transformer coil of coiling not tight, thereby affect its electrical strength and mechanical strength.
Summary of the invention
The technical problem that the present invention mainly solves is to provide 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 present invention adopts is: provide a kind of transformer foil around low-voltage coil positioner, comprise coil die, row and interior registration part in coil, in described coil, row is smooth in a flat end of coil die, in described coil, row's upper end is provided with an interior gang milling location notch, 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, described interior registration part is stuck in row in coil the flat end of coil die, then by bolt, be fixedly connected with coil die.
In a preferred embodiment of the present invention, described coil die is oval cylindrical shell.
In a preferred embodiment of the present invention, in described coil, row is strip structure.
In a preferred embodiment of the present invention, described coil die is provided with the bolt hole corresponding with bolt hole on interior registration part.
The invention has the beneficial effects as follows: used in transformer coil positioner of the present invention, during the coil of coiling transformer, with interior registration part, row in coil is stuck in to the flat end of coil die, then by bolt, be fixedly connected with coil die, after coiling completes, take out interior registration part and coil die, by this used in transformer coil positioner, guaranteed the transformer coil good looking appearance of coiling, and compactness is good, there is good electric and mechanical strength.

Refer to Fig. 1,2,3 and 4, the invention provides a kind of transformer foil around low-voltage coil positioner.This transformer foil comprises with positioner around low-voltage coil arranges 2 and interior registration part 3 in coil die 1, coil, in coil, row 2 is smooth in a flat end 11 of coil die 1, in coil, row 2 upper end is provided with an interior gang milling location notch 21, interior registration part 3 is the structure of right angle bending, one end of this interior registration part 3 is provided with the projection 31 corresponding with interior gang milling location notch, and the other end is provided with bolt hole 32.
Coil die 1 in the present invention is oval cylindrical shell; In coil, row 2 is strip structure.
The used in transformer coil positioner that the present invention discloses, during the coil of coiling transformer, with interior registration part, row in coil is stuck in to the flat end of coil die, then by bolt, be fixedly connected with coil die, after coiling completes, take out interior registration part and coil die, by this used in transformer coil positioner, guaranteed the transformer coil good looking appearance of coiling, and compactness is good, there is good electric and mechanical strength.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
