Description

A kind of enamel-cover combined shifting lead

Technical field

The utility model relates to the production technical field of transposed conductor, particularly relates to power transformer transposed conductor field, is specially a kind of enamel-cover combined shifting lead.

Background technology

Transposed conductor means and is combined into the enameling copper strap wire of certain radical two row that wide face contacts with each other, and on request on two row enamelled wires and below do the same transposition turned to along leptoprosopy, and make the continuous tight enclosure of multilayer with electrician's insulating paper strip and form.The transposition core of current formation transposed conductor forms by its single enameled sheet wire successively cycle transposition; once transposition core is too much; the core that such as replaces reaches 60 ~ 80; its transposition cycle length will reach 4m ~ 5m; and the coiling requirement of transformer coil when a complete transposition cycle length of transposed conductor is less than 3m usually, could be met; when the length of transposition cycle is more than 3m; enameling copper strap wire play can be produced in coil-winding process; cause enameling copper strap wire damage in insulation, cause short circuit.Chinese patent CN201210295349.3 discloses and makes the same cycle transposition turned to realize shortening transposition cycle length along leptoprosopy by every two enameling copper strap wires of adjacent superposition simultaneously, but find in the process of Transformer Winding coiling eddy current loss produce possibility high, we through great many of experiments find its reason be transposed conductor enameling copper strap wire between there is potential difference.

Summary of the invention

For the problems referred to above, the utility model provides a kind of enamel-cover combined shifting lead, it is little that it can not only realize transposition cycle length, avoid enameling copper strap wire generation play, damage in insulation and short circuit phenomenon in coil-winding process, and the enameling copper strap wire length that can realize further through transposition is impartial, without potential difference after coiling Transformer Winding, reduce the possibility that eddy current loss produces.

Its technical scheme is such, it comprises transposition core, two row that described transposition core is superimposed to form side by side by wide mutually by even number root enameling copper strap wire, often arrange that two neighbouring enameling copper strap wires form one group, each group enameling copper strap wire makes the same cycle transposition turned to along leptoprosopy successively, it is characterized in that: after each group enameling copper strap wire circulates one week, single enameling copper strap wire does the same transposition turned to along leptoprosopy successively, makes two enameling copper strap wires forming each group enameling copper strap wire realize replacing up and down.

It is further characterized in that:

Between described two row enameling copper strap wires, pad has lining paper;

Described transposition core outsourcing polyester guipure.

After adopting structure of the present utility model, transposition core carries out double joint transposition, effectively shortens complete transposition cycle, effectively can avoid enameling copper strap wire generation play, damage in insulation and short circuit phenomenon in coil-winding process, guarantee Product quality and safety; Transposition core is after double joint transposition, carry out single transposition again, realize the exchange of adjacent two transposition core upper and lower positions, the adjacent two transposition core length making simultaneously to replace are equal, without potential difference after coiling Transformer Winding, reduce the possibility that eddy current loss produces.
