Abstract
The utility model provides a varnished cloth combination transposed conductor, it is little that it not only can realize replacing the cycle length, avoids taking place drunkenness, insulating damage and short circuit phenomenon at coil winding in -process varnished cloth copper ribbon line to can further realize not having the potential difference through the varnished cloth copper ribbon line length equalling of transposition behind coiling transformer winding, reduce the possibility that eddy current loss produced. It is including the transposition sinle silk, and the transposition sinle silk makes up side by side two by even number root varnished cloth copper ribbon line according to each other stack of wide facial features, whenever list down adjacent two varnished cloth copper ribbon lines constitute a set of, organize varnished cloth copper ribbon line and do the same circulation that turns to along the leptoprosopy in proper order and replace its characterized in that: after each group's varnished cloth copper ribbon line circulation a week, the same transposition that turns to is done along the leptoprosopy in proper order to single varnished cloth copper ribbon line for transposition is from top to bottom realized to two varnished cloth copper ribbon lines that constitute each group's varnished cloth copper ribbon line.
Description
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.

Fig. 2 is the process schematic of the utility model enamel-cover combined shifting lead complete transposition cycle.
Fig. 2-1 is the structural representation after the partial enlargement of empty frame part S1 in Fig. 2, and concrete expression often organizes enameling copper strap wire makes the same cycle transposition turned to successively process along leptoprosopy.
Fig. 2-2 is the structural representation after the partial enlargement of empty frame part S2 in Fig. 2, and concrete expression often organized enameling copper strap wire cycle transposition after one week, and single enameling copper strap wire makes the same transpose process turned to along leptoprosopy successively.
Fig. 2-3 is the structural representation after the partial enlargement of empty frame part S3 in Fig. 2, and the enameling copper strap wire of often organizing carried out after the single enameling copper strap wire transposition of concrete expression replaces successively with the process of completion transposition cycle.
Embodiment
As Fig. 1, Fig. 2, shown in Fig. 2-1 to Fig. 2-3, this enamel-cover combined shifting lead 101 comprises some transposition cores, in Fig. 1 11, 12, 21, 22, 31, 32, 41, 42, 51, 52 are 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 two neighbouring enameling copper strap wires and form one group, each group of enameling copper strap wire makes the same cycle transposition turned to along leptoprosopy successively, and as shown in Fig. 2-1, enameling copper strap wire 11 and 12 is one group, enameling copper strap wire 11 is superimposed on above enameling copper strap wire 12, and enameling copper strap wire 21 and 22 is one group, enameling copper strap wire 21 is superimposed on above enameling copper strap wire 22, and enameling copper strap wire 31 and 32 is one group, enameling copper strap wire 31 is superimposed on above enameling copper strap wire 32, and enameling copper strap wire 41 and 42 is one group, enameling copper strap wire 41 is superimposed on above enameling copper strap wire 42, and enameling copper strap wire 51 and 52 is one group, enameling copper strap wire 51 is superimposed on above enameling copper strap wire 52, and these 5 groups of double joint enameling copper strap wires make the same cycle transposition turned to along leptoprosopy successively, after each group enameling copper strap wire circulates one week, single enameling copper strap wire does the same transposition turned to along leptoprosopy successively, two enameling copper strap wires forming each group enameling copper strap wire are made to realize replacing up and down, as shown in Fig. 2-2, enameling copper strap wire 12 is superimposed on above enameling copper strap wire 11, enameling copper strap wire 22 is superimposed on above enameling copper strap wire 21, enameling copper strap wire 32 is superimposed on above enameling copper strap wire 31, enameling copper strap wire 42 is superimposed on above enameling copper strap wire 41, enameling copper strap wire 52 is superimposed on above enameling copper strap wire 51, due to single enameling copper strap wire replace successively after cannot arrive cycle period, therefore as Figure 2-3, proceed transposition successively between group and group with completion transposition cycle, between described two row enameling copper strap wires, pad has lining paper 102, described transposition core outsourcing polyester guipure 103.
