Description

(54) CONTINUOUS WINDING OF THE TRANSFORMER

one

The invention relates to electrical engineering and can be used in the manufacture of transformers (reactors).

A continuous winding 5 of a transformer is known, in each coil of which a different number tn is made by different parallel conductors.

The disadvantage of the known winding in- “O

Increased manufacturing effort.

A continuous winding1, of a transformer, containing n coils wound with m parallel wires, 5 with the number of wires in each coil, with transitions between adjacent coils, is known. ,

However, a high voltage between 20 neighboring coils requires an increase in the channel between them, which leads to an increase in the winding height, a low filling factor of the magnetic core window, an increase in the consumption of active materials, and therefore lower the efficiency of the transformer.

The purpose of the invention is to reduce the size and consumption of active materials of a transformer, 30

This goal is achieved by the fact that in the continuous winding of the transformer, there are n coils, wound parallel parallel wires with the number of wires in each coil PIP. , m parcel wires are divided into k groups, located in the axial direction and forming k parallel winding branches, each of which contains g-- coils connected in series with VU number of turns in each, wound with W parallel wires and connected by S transitions with coils located through k-1 coils, where W is the number of turns in the winding.

In FIG. 1 schematically shows a known winding, general view; Fig 2 is the same, top view; in fig. 3 - the proposed winding, a general view; in fig. 4 - the same, top view.

Known continuous winding (Fig. 1 and 2) consists of n coils; 1-8, containing coils wound with two m parallel wires 9 and 10. Two (-1 -2) turns are wound in each coil with each parallel wire 9 and 10. Each two ka kalas 11–17
