Between foil 3, second insulating layer 4 is set to 3 bottom of second layer foil, first layer foil 1, the head end of second layer foil 3 and first layer foil 1, the
The end of two layers of foil 3 is located at transformer cylinder the same side, the head end of first layer foil 1, the head end of second layer foil 3, first layer foil 1
End, second layer foil 3 end copper bar 5 is respectively welded.
Optimization, first layer foil 1,3 head end of second layer foil, two copper bars 5 are completely separated with insulator, first layer foil 1, second
The layer foil copper bar 5 of 3 end two is completely separated with insulator.
The utility model is realized in this way：A kind of combined transformer low pressure winding, winding include two input terminal copper
Row, same specification first layer foil 1, second layer foil 3, the first insulating layer of sandwiched 2, second layer foil 3 between first layer foil 1, second layer foil 3
Bottom, which is put, sets second insulating layer 4, and first layer foil 1,3 head end of second layer foil weld copper bar, first layer foil 1, the first insulating layer 2, the
Two layers of foil 3, second insulating layer 4 are wound together, and first layer foil 1,3 end of second layer foil weld copper bar, first layer foil 1, the
Two layers of foil 3 head end, two copper bar insulator are completely separated, and first layer foil 1, second layer foil 3 end two copper bar insulator are complete
It separates entirely.
Compared with prior art, the utility model advantageous effects are：
It is this simple and compact for structure, winding filling rate is improved, cost, the coiling simultaneously of first layer foil, second layer foil, nothing are reduced
Secondary package is needed, mechanical performance is improved.
