Description

one

The invention relates to electrical engineering, in particular to the design of the windings of transformer sylvjzh.

The aim of the invention is to reduce the labor intensity and material consumption of the continuous winding structure.

Figure 1 schematically shows a continuous winding wound with three parallel wires; FIG. 2 shows a winding wound with four parallel wires; 3-5, the transitions between the turn-on coil and the group of permanent coils, variants, (radial size of the turn-on and permanent coils, the same),

Continuous winding is made m 1 parallel wires, for example in figure 1 - three parallel wires () in a turn, in figure 2 - four parallel wires (). The winding contains groups of 1 constant coils wound each. Wrap around

The fixed coils alternate in height along the winding with single turn-over coils 2 wound with p turns along m parallel wires, i.e. in group J of permanent coils, the wire turns are arranged in row along the axis of the winding, in the crossover coil 2 also in row, but in the radial direction,

Continuity of winding is achieved by shifting the turns in the transfer coils so that one transition is outside the winding, the other inside. Typically, the winding of the continuous winding starts with winding the crossbar: the coil, whose wires are located in a row in the radial direction. Then, a transition 3 (Figures 1-3) is performed at the level of the outermost turn, for example, internal, into group 1 of constant coils, the wire is positioned in the axial direction of the winding and continuing to wind to a radial size equal to the size of the cross coil 2.

Next, the transition 4 (Figures 1 and 4) is also carried out at the level of the outermost turn, for example, the outer one, from group 1 of the permanent coils to the transfer coil 2, etc. The transition 5 from the transfer coil 2 to the group 1 or vice versa is performed (figure 5) with simultaneous transposition of the wires in the middle of the winding.

In the operating mode between constant coils forming a group, there are no electrical effects (voltage and impulse frequency), due to which channels or insulating washers between them are not required, the filling ratio of the magnetic window of the active material increases, material consumption decreases, losses electricity, increases the efficiency of the transformer as a whole. The ratio of the number of switch coils to the total number of coils of a winding, for example wound in accordance with the invention with three parallel wires, is

Reducing the number of switch coils in the continuous winding allows reducing the labor intensity of its manufacture by up to 5% during mass production.
