Description
Technical field
The utility model relates to transformer part field, especially a kind of low voltage winding in transformers structure.
Background technology
Transformer utilizes electromagnetic induction principle a kind of voltage and current of grade to be converted to the voltage and current of another kind of grade of same frequency and the equipment of electric energy transmitting, the circuit part of the coil constitution equipment of transformer itself, it is directly connected with outside electrical network, be most important parts in transformer, be therefore called as " heart " of transformer.Coil is the basic element of character of transformer voltage of transformation, and coil is made up of the different numbers of turn, and the one turn voltage due to different coil is the same, therefore, needs to make coil have the different numbers of turn, reaches different voltage.Transformer operationally, by electric current in coil, produces resistance loss in coil-conductor, can cause the efficiency of heating and reduction transformer.Coil uses the metal that conductivity is high to make for this reason, and conventional conductor is copper.The cross section of transformer coil of the prior art is generally circular, and be generally solid construction between coil turn, its shortcoming is: 1. because circular configuration volume is larger, spent copper material is many, the space occupied is also large, and because coil is enclosed within core limb, the excessive core volume that also causes of the volume of coil is excessive, not only limit cost and be not easy to transport, installation; 2. coil-conductor is by producing amount of heat during electric current, owing to being solid construction between coil turn, is unfavorable for that heat is discharged, under coil is in higher temperature conditions for a long time, accelerates the aging of product, make the life-span of product very limited.
Utility model content
For the problems referred to above of the prior art, the utility model proposes a kind of low voltage winding in transformers structure.
The technical solution of the utility model is: comprise coil layer, air channel, air channel stay, end insulation and copper busbar, wherein: the cross section of described coil layer is Long Circle and comprises inner core coil and urceolus coil, described coil layer is made up of the Copper Foil of alternate combinations and layer insulation, and the inner ring of described inner core coil and the outer ring of urceolus coil are equipped with appearance insulation;
