Description

The double cake formula Transformer Winding of single turn

Technical field

This utility model relates to for field of power distribution, particularly to the double cake formula Transformer Winding of a kind of single turn.

Background technology

In furnace transformer in being applied to low-voltage, large-current electric gas engineering and rectifier transformer, owing to transformer output voltage is the lowest, electric current is very big, and low-pressure side usually uses by the winding construction of multiple pairs of cake line segments combinations.Coil winding for convenience, traditional theory and technique think that double cake line segment number of turn cannot be below 2 circles, so in particular cases would have to the technical-economic index sacrificing transformator to meet the manufacturability that coil manufactures at some.

Summary of the invention

In order to solve above-mentioned technical problem, this utility model provides a kind of simple in construction, single turn easy to make double cake formula Transformer Winding.

This utility model solves the technical scheme of the problems referred to above: the double cake formula Transformer Winding of a kind of single turn, including multiple pairs of cake line segments, the parallel conducting wire radical of each pair of cake line segment is N, N is even number, double cake line segments include First Line cake and the second line cake that stacking arranges, wherein the parallel conducting wire radical in First Line cake is N/2, transposition number is N/2, parallel conducting wire radical in second line cake is N/2, transposition number and the position of the second line cake are corresponding with First Line cake, the starting as double cake line segment that connect together of starting with the second line cake of starting of First Line cake, the tail head of First Line cake and the tail head of the second line cake connect the tail head as double cake line segments, thus constitute a double cake line segment；All pairs of cake line segments are superimposed composition Transformer Winding.

In the double cake formula Transformer Winding of above-mentioned single turn, the electric number of turn of each pair of cake line segment is a circle.

The beneficial effects of the utility model are: the of the present utility model pair of cake line segment includes First Line cake and the second line cake that stacking arranges, parallel conducting wire radical in First Line cake, the second line cake is N/2, transposition number is N/2, whole transformer winding structure is simple, parallel conducting wire radical in each pair of cake line segment is N, and the electric number of turn is a circle, and breaching the minimum number of turn of traditional structure requirement is the limitation of 2, increasing the degree of freedom of design, the technical-economic index of transformator more optimizes.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the structural representation of double cake line segments in Fig. 1.

Detailed description of the invention

With embodiment, this utility model is further described below in conjunction with the accompanying drawings.

As it is shown in figure 1, this utility model includes K double cake line segment, the parallel conducting wire radical in each pair of cake line segment is N, and the electric number of turn is a circle.The each pair of cake line segment all includes First Line cake and the second line cake that stacking arranges, as shown in Figure 2, a1 in Fig. 2, a1 ' and x1, x1 ' is respectively the starting of First Line cake and the second line cake in double cake line segment, tail head, it is even number that parallel conducting wire radical in First Line cake a1x1 and the second line cake a1 ' x1 ' is N/2, N.During double cake line segment coiling, first around a1x1 line cake, its parallel conducting wire radical is N/2, and transposition number is N/2, and bit positions selects stay number n to determine by traditional transformer winding technique method according to parallel conducting wire radical N and Winding Design.The parallel conducting wire radical of line cake a1 ' x1 ' is also that N/2, transposition number and bit positions must be as corresponding in Fig. 2 with a1x1 line cake.After line cake coiling completes, a1 and a1 ' that start connects together starting as double cake line segment, and tail head x1 and x1 ' connects together and form the tail head as double cake line segments, thus forms a single turn pair cake line segment.

I.e. can be superimposed on together according to above-mentioned same method coiling k double cake line segments and be combined into the double cake formula Transformer Winding of single turn shown in Fig. 1.Double cake line segment number k are calculated by design of transformer and determine, the connected mode between double cake line segments is required to determine by transformer device structure.
