It connects, is looped around on toroidal core 2, copper post 3 and the arrangement annular in shape inside and outside toroidal core 2;And the setting of copper sheet 5 is existed
Above and below toroidal core 2;Several copper posts 3 are respectively set inside and outside toroidal core 2, are arranged in toroidal core 2
It is connected between side and the copper post 3 in outside with copper sheet 5, by changing the connection type between copper sheet 5 and copper post 3;It is respectively formed institute
The primary 1 and transformer secondary output 4 stated;The circular direction direction of transformer secondary output 4 and the circular direction of primary 1
Unanimously.Tap is drawn in the copper post of 4 different location of transformer secondary output, forms different voltage ratios.
Primary 1 further includes several first copper sheets 11 and several first copper posts 12;First copper post 12 passes through the
One copper sheet 11, which joins end to end, to be connect;Form magnetic circuit loop;Primary 1 is located to the inner ring side or outer ring side of toroidal core 2
It is ok, does not influence transformer use;It is fixed with brass screws 8 between first copper post 12 and the first copper sheet 11.
Transformer secondary output 4 further includes several second copper sheets 41 and several second copper posts 42;Second copper post 42 passes through the
Two copper sheets 41, which join end to end, to be connect;Form magnetic circuit loop;Transformer secondary output 4 compares successively according to different voltage into toroidal core 2
Heart circular row;It is fixed with brass screws 8 between second copper post 41 and the second copper sheet 42.
Insulating layer 6 is set between primary 1 and transformer secondary output 4;It is put in first copper sheet 11 and the first copper post 12
Insulating sleeve 7;Insulating sleeve 7 is equally put in second copper sheet 41 and the second copper post 42;First copper sheet 11, the first copper post 12 and
Two copper sheets 41, the second copper post 42 put on insulating sleeve 7 position and between it is insulated from each other.
Length of the length of first copper sheet 11 less than the second copper sheet 41;The height of first copper post 12 is less than the second copper post 42
Highly.Here the length of two copper sheets is not laid down hard and fast rule, and copper sheet can if in the case where primary circle number is less, position is enough
With equally long.
In conjunction with shown in attached drawing 1- attached drawing 5, a kind of embodiment of 3 transformer secondary outputs is provided, is come from structure of the invention
It sees, if it is desired to obtaining more voltage ratios, as long as determining size, the size of toroidal core used, is determining magnetic core size
Afterwards, suitable copper post is selected, and has measured the pitch-row inside and outside toroidal core between copper post, so that it is determined that the size of copper sheet, and with
This carries out annular arrangement to the center of toroidal core, can theoretically form the different voltage ratio of N kind, in the present embodiment
By taking 3 transformer secondary outputs as an example,
The place of closest toroidal core 2 is arranged in primary 1, and transformer secondary output 4 is respectively successively to annular magnetic
2 center of core is drawn close, and is respectively set 3 layers, and as shown in Fig. 5, totally four layers of the transformer in the present embodiment, each layer is by copper post and copper
Piece composition leads the circle of wire-wound magnetic core 12 (number of plies and circle number of transformer can according to need and be adjusted).Innermost layer is transformer
Primary, three layers of outside are transformer secondary output, are connected between three secondary by conducting wire.From the two of any one copper post of primary
End, draws two conducting wires, the primary as transformer.From any point extraction wire on the 2nd circle as transformer secondary output
Common end.It then can be according to demand in any position extraction wire of 2,3,4 circles, to reach required no-load voltage ratio.From
This transformer sample maximum no-load voltage ratio known to structure is 1:3, can be by changing primary if necessary to bigger no-load voltage ratio
The number of plies of number or transformer is enclosed to realize.
Meanwhile in such as the present embodiment in, the height of copper post 3 and the ectonexine pitch-row of copper sheet are specific as follows:
The height of copper post 3 and the ectonexine pitch-row of copper sheet 5 increase with the level of transformer secondary output as can be seen from the above table
