In the time of the coiling of conventional transformer pitch of the laps, convenient for coiling, each annular line segments group all is to carry out from inside to outside.Therefore between adjacent two layers annular line segments group, in the transition, every section transition wire must be guided to inner surface from the coil outer surface.Common processing method all is the outer lead bending certain angle with the good annular line segments group of coiling, passes that the space extends to the coil inner surface between the annular line segments group, and then carries out the coiling of next adjacent annular sets of line segments.Though such winding method meets the custom of conventional coiling very much, because every section transition wire all needs to extend to the coil inner surface from the coil outer surface, the transition route is longer, and copper material consumption is very big, thereby has increased the cost of transformer.Simultaneously, the transition wire bending produces outwards outstanding turning, is unfavorable for the circular design of transformer profile.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of transformer coil is provided, transition wire between its adjacent two layers annular line segments group is postponed along annular line segments group coiling direction, be distributed in the external peripheral surface or the inner circumferential surface of annular line segments group, save copper loss, also made coil shape more meet circular effect simultaneously.
The purpose of this utility model realizes by following proposal: this transformer coil, its inner periphery and iron core socket, described transformer coil comprises a plurality of along iron core axially-aligned and the annular line segments group that is connected by branch-cut bridge, outwards the annular line segments group of coiling, the annular line segments group of coiling outside to inside in described annular line segments group comprises, described in outwards the annular line segments group of annular line segments group, the coiling outside to inside of coiling along iron mandrel to alternately arranging; Described transition wire comprises inner periphery transition wire, excircle transition wire, it is postponed along annular line segments group coiling direction, and is corresponding to excircle transition wire or the connection of inner periphery transition wire between the annular line segments group of the annular line segments group of promptly adjacent interior outside coiling, coiling outside to inside.
For realizing the utility model better, described transition wire is "~" shape, and the arc section at its two ends is connected with two adjacent annular line segments groups respectively.
The multiturn sets of line segments that described annular line segments group forms for the solid conductor coiling is perhaps for multiple conducting wires and around the multiturn sets of line segments that forms.
Be provided with axial oil duct gap between described adjacent two annular line segments groups, be provided with at least one cross-over block in each axial oil duct gap.
Described cross-over block adopts the corrugated layer pressboard to make.
Compared with prior art, the utlity model has following advantage and beneficial effect: described transition wire directly is distributed in the outer circumference surface or the inner peripheral surface of annular line segments group, do not need to pass the oil duct passage between adjacent two layers annular line segments group, the transition route shortens, therefore can save copper material, reduce the transformer cost.Because transition wire is postponed along coil coiling direction, more meet the requirement of transformer circular design simultaneously.
