Electric transposed wire

FIELD: electricity.

SUBSTANCE: electric transposed wire consists of two columns laying next to each other, in every of which there are several flat wire strands arranged one onto another and insulated, having rectangular section, which along their whole length pass from the first column by means of bending to the second column, and then having passed along the specified section, again return into the first column, at the same time strands (7) of wire have a straight section, without bends, with sufficient length (L), at least at one end.

EFFECT: simplified processing and arrangement of electric connection.

The invention relates to an electrical transposed wire consisting of two adjacent columns, each of which, lying on top of each other, are flat insulated from each other electrically conductive wires having a rectangular cross-section, and throughout its period of wires of the first column are curved so that they are in the second column, and after a given length of the passage return to the previous stack (see EP 1079500 A1).

Such transposed wires, in accordance with EP 1079500 A1, are used for manufacturing of windings of electrical devices such as transformers. These wires are manufactured with great lengths, for example, 5000 m, and wound on the coil. At the installation location transposed wires they are retracted from the coils and they are winding. In order to have the minimum possible magnetic and electric effects on these wires in electrically active winding, the entire length of the transposed wires in its manufacture are continually progressive change in the position's wires throughout the cross section transposed wires in order lying on top of the wire conductor of the first pillar by limb passed in the second column, and the wire conductor lying at the bottom of the second column into the first column. Made of such transposed wire winding on the place of production is electrically connected to other parts. For this purpose the ends of the individual conductors of the wires stand out from the columnar patterns and prepared for subsequent processing operations.

While wires are electrically connected to each other to form a single wire. After processing cores transposed wires again placed back in their place in the columns.

The basis of the invention lies in the task of making the transposed wires described above so that the end is made in a similar way winding could be handled in a simple way.

This task, in accordance with this invention, is solved in that the core wire, at least at its end, run straight without bending with sufficient length to allow the processing, it is preferable to carry out the electric connection. This transposed wire designed in a way that made him winding it easier to electrically join. To do this, you need to direct all lived the wire to remove the insulation and electrically connecting them with other wires. This can in principle be carried out fully automatically. A straight line passing the conductor wires after they are processed can be very simply laid in his floor is laid in the columns transposed wires. This transposed wire made as uniform wire, using conventional equipment can be provided with an electrical connector or connect with another element in any other way. For all the working practices of the winding itself do not need to touch. Wires wires do not change their position in the winding.

Strands of wire, at least at the end of the transposed wires are straight. On the other their end, with a corresponding performance of electrical components that must be attached to them, in certain cases, you can refuse rectilinear form.

The linear form's wires has the advantage of minimum length of 0.20 m But if necessary it can be up to 2,00 m

An example showing the object of the invention is presented below.

Figure 1 shows schematically the electrical device from which the winding is made of transposed wires

figure 2 - the end of the transposed wires according to the present invention.

Transposed wire D, the end of which is presented in figure 2, formed in the coil 1, which is incorporated in, for example, the transformer 2. Winding 1 has two ends 3 and 4, where the transposed wire D is electrically connected to other elements. This is, for example, can be output 5 on the one hand and the contact block 6 on the other the part.

Transposed wire D consists of a flat electrically isolated from each other lived 7 of rectangular cross-section, which are arranged in two columns 8 and 9, located near. They are made of, for example, of copper or aluminium. During manufacture of the transposed wires D was constantly changing place wires 7 wires from column 8 to column 9 on the one hand and from column 9 column 8 with the other hand. With this in place 10 changes position each lying above vein 7 wires from the first column is column 8, unbent so that she lay on top of the second column, here the column 9. At the same time in the 11 position changes, respectively, below vein 7 wires from the second column unbent so that it takes place in the first column.

The transposed wires D, in accordance with the invention, the ends of the lived 7 wires, with at least one side, are linearly on the length L, which is preferably from 0.2 m to 2.00 m along the length L there is no change in the position's wires, i.e. wires wires in the above sense can be easily processed and put back in the position they were in his column.
