Поставленна цель достигаетс тем, что проекции всех основных проводников на вспомогательный не пересекают друг друга. При этом основные проводники , расположенные в одной и той же плоскости, выполнены различной ширины , увеличивающейс от одного крайнего основного проводника к другому. Кроме того, рассто ни между ОСНОВНЕЛЛИ проводниками, расположенными в различных плоскост х, и вспомогательным проводником выполнены увеличивающимис от одного крайнего основного проводника к другому.The goal is achieved by the fact that the projections of all the main conductors onto the auxiliary do not intersect each other. In this case, the main conductors located in the same plane are made of different widths, increasing from one extreme main conductor to another. In addition, the distances between the BASEDNEWELES conductors located in different planes and the auxiliary conductor are made increasing from one outermost conductor to another.

Claims

FIG. 1, the main conductors in the flat wire, located in one plane, are made of different widths, increasing from one extreme main conductor to another, for example, according to the 1: 2: 3 law: ... where n is the number of the main conductor. . FIG. Figure 2 shows the structure of a flat wire, in which the distances between the main conductors, located in different planes, and the auxiliary wire increase from one extreme main conductor to another, for example, according to the 1: 2: 3 law: ...: n, where n - number of the main conductor. The wires shown in FIG. 1 and 2 are manufactured, for example, by extrusion. The auxiliary conductor can be used as a shield. Connecting the main conductors in pairs, it is possible to obtain a series of values of wave impedances, different from the values of wave impedances of individual lines. Below, using the example of a broadband high-frequency transformer, we justify the construction of a wire when the width of the main conductors located in one plane or the distance between the main conductors located in different planes and the auxiliary from one extreme main conductor to another is changed, for example, according to Law 1: 2: 3: ...: p. FIG. 3 shows a transformer containing a toroidal magnetic core 4 and windings made of flat wire. The primary winding is formed by an auxiliary conductor (adjacent to the core), the secondary winding is made up of series-connected main conductors. Winding included in the autotransformer circuit. The primary windings are formed by conductors 5 and 6, the secondary leads are made by conductors 7. and 8. In FIG. Figure 4 shows the equivalent circuit diagram of a high frequency transformer (without taking into account the capacitive coupling between the conductors of the secondary winding). The primary winding is represented as parallel-connected first conductors of line segments (auxiliary conductor is represented as parallel-connected first conductors), the secondary one - in the form of successively connected second conductors of line segments. The wave impedances of the line segments Z, Z. Zj, ... Z refer to 1: 2: 3: ...: When the transformer is made from the proposed flat wire, less dissipation inductance and dynamic capacitance are obtained and higher upper cut-off frequency, than a transformer made of a known flat wire. The dissipation inductance of the transformer (Fig. 3) G1 is reduced to the down-winding, is approximately equal to j, er U, 1, .- -, m s - .0 where L is the linear inductance of the line segment formed by the i-th conductor of the secondary and primary windings; 1 - the length of the conductors of the primary and secondary windings; - transformation ratio by voltage (i 1, 2, 3, p). The dynamic interwinding transformer capacity Cd is defined by the expression C lot () A%, where is the linear capacitance of the i-th conductor of the secondary winding relative to the primary one. It can be seen from the expressions for Lg and Cd that the contribution of each conductor of the secondary winding to the total inductance of dissipation is the same, while the contribution of the same conductors to the total interwinding dynamic capacitance is different. The minimum value of the product L5CD occurs if the main conductors forming the secondary windings and located in the same plane are made of different widths, increasing from one extreme main conductor to another, for example, according to the 1: 2: 3 law: ...: p (Fig. 1), the distance between the main conductors forming the secondary windings and located in different planes and the auxiliary conductor (primary winding) increases from one extreme main conductor to another, for example, according to 1: 2: 3 : ... .p (fi . 2). A transformer made on the basis of the proposed flat wire gives an increase in the upper cut-off frequency of up to 13% with N ± 4, up to 20% with N 5 and up to 27% with N 6. Claim 1. The flat wire containing ribbon conductors located in different planes and isolated from each other, one of which (auxiliary) is made across the entire width of the wire, and the rest (main) are located in at least one plane parallel to the auxiliary conductor, on one side of it, characterized in that to simplify lk and

installation and reduction of mutual effects, the projections of all the main conductors on the auxiliary do not cross each other.

2. The wire according to claim 1, distinguishes 1 and so that, in order to expand the range of transformation ratios when using wires in transformers, the main conductors located in the same plane are made of different widths increasing from one extreme main conductor to to another.

3. The wire of claim 1 is distinguished by the fact that, in order to expand the range of transformation ratios when using wires in transformers, the distance between the main conductors located in different planes and the auxiliary conductor increases from one extreme main conductor to to another.
