Description

The invention relates to electrical engineering, in particular to the windings of high-voltage power induction devices.

Induction devices (transformers, reactors) use various winding designs. The most technologically advanced and reliable in a normal operating mode is a continuous winding.

A continuous winding is known in which the voltage between adjacent coils corresponds to the voltage of one coil in the coil-C channel.

However, in this winding, due to the large current and the need for intensive cooling, each parallel forms its own coils. Each coil of the same number has a cooling channel. Transitions of both parallels are located in the mezhkatushechno channel. This reduces the electrical strength of the channel, requires additional space in it and an increase in the height of the winding.

Closest to the proposed technical essence and the achieved result is a winding containing two parallels, the coils of which alternate through one. Each parallel forms its coils from consecutively connected turns. Coils are placed in the composition of the winding so that the adjacent, above and. bottom for each coil along;. The entire winding is a coil of another parallel, i.e. parallel coils alternate through one along the entire winding.

The winding is characterized by a simple technology of winding coils and making transitions 2.;

The disadvantage of the winding is a large voltage between non-identical coils, equal to the voltage of two coils, whereas the voltage between the coils of the same name is zero, i.e. only the cooling function of the channel between these coils is used and its electrical strength is not used. These circumstances require an increase in the insulating gap between non-named coils, which ultimately leads to an increase in the winding height and an increase in the consumption of materials in the manufacture of a transformer.

The purpose of the invention is to reduce the overall dimensions and material consumption by reducing the insulating gaps by reducing the voltage in them.

The goal is achieved by the fact that in the winding of an induction device of two parallel wires, in which the turns of one parallel spruce wire form a series connected odd layers

or coils, and the turns of the other parallel are consecutively connected even layers or coils, with the numbers of turns of odd and even layers or coils being equal to each other, according to the invention, the initial turn of each odd layer or coil is located against the final turn of each subsequent even layer or coil.

This makes it possible to reduce the voltages in the insulation gaps between the coils or layers and thereby reduce their value, which makes it possible to reduce the overall height

winding and reduce the consumption of materials in the manufacture of induction apparatus.

FIG. 1 schematically shows the cross section of the coil winding

buildings; in fig. 2 - offered

winding layer structure.

The winding of an induction apparatus, for example, a transformer or a reactor, contains two parallel wires P and P of the wires, the shape of the memory connected to the series connected coils (1-15).

The coils of one parallel of the GG wires form a series of odd-numbered layers or NK coils, and the coils of another parallel U -tiocandno-connected even-numbered layers or HK coils. The initial coil of each odd layer or coil of the NC is located against the final coil of each even layer or coil of the Cheka.

Each parallel: has the same number of turns, i.e. contains turns of the same serial numbers,

but the order of location of their counter | PALOZNY (shown by arrows), for; of which the initial turn of one parallel

in the coil winding (Fig. 1) it is located on the outer side (surface) of the winding, and the initial turn of the second pair is located on the inner side. In the layer winding initial

coils of parallels are located at opposite ends of the winding, i.e. one at the beginning and the other at the end.

Oinbyme odd coils NK Parallel P. coils and even HK Pa Pa coils contain turns of the same order numbers. The odd coils or NC layers are successively interconnected by the NS transitions, and the even layers or NC coils are interconnected by the ES transitions. Odd coils or layers of NC parallel вдоль along the entire winding alternate with even-numbered coils or layers of ancillary parallel,. those. arranged so that adjacent to each coil or layer is a coil or layer of another parallel. In the spatial arrangement, the sequence of turns in the coil forms a ring (disk), and in the layer a cylinder. The axis of symmetry of the winding section passes through the middle turns of coils or layers. . In the example shown, each even and odd layer or coil is 5 turns each. The initial turns 1, b, and 11 odd layers or NK coils are located opposite respectively the final turns of even Orois 5, 10, and 15.: In the operating induction apparatus in the proposed winding, due to the opposite direction of successively similar turns in pairs of adjacent coils or layers, the voltage between the coils proportional to the difference in the number of opposite turns of these coils, and throughout it is the voltage of the Single coil, since the voltage of the two coils is distributed equally to both types of channels (insulation and lazhdaklscho known in the windings). The voltage between the junction of the connecting junction C and the coil will also be | N: the radiation of one coil. The use of the proposed winding will allow to reduce the consumption of materials for the manufacture of the induction apparatus by reducing inter-wire or interlayer insulating gaps by reducing the voltage in them. In a number of cases, the dimensions of the channels between the like and non-named inter-wire interlayer canals can be made of cooling conditions, i.e. minimal. Due to this, the height of the winding can be reduced, which will reduce the height of the rods and side PM of the magnetic core by the same amount and reduce the material consumption for its manufacture. JCaHama in the low voltage winding is reduced accordingly. A two-fold decrease in the intermotor tension reduces the component strength along the winding surface, which makes it possible to reduce the insulating distance between the windings, i.e. bite the diameter of them. It is possible to reduce the diameter of the magnetic core.
