RU1167U1 - The magnetic circuit of the induction apparatus - Google Patents

Abstract

The magnetic circuit of the induction apparatus, containing two U-shaped twisted elements from a strip of electrical steel and one I-shaped part from plates of electrical steel, characterized in that the U-shaped elements are composed in the U-shaped part of the magnetic circuit so that two aligned rectilinear sections U- of the shaped elements form the central rod, the other two — the lateral yokes, the middle, curved - the end upper yoke, and the I-shaped part closes the ends of the U-shaped elements, forming the end lower yoke of the magnetic circuit.

Description

A MAGNETIC WIRE FOR INDUCTION APPLICATION A useful model - refers to the area of electrical equipment and coins to be used in single-phase transformers and small reactors, for example, in the ignition reactors there are several logically ordered units, this is a little bit different Due to the necessity of opening to the central head of the obiotok, it is difficult to directly assemble the magnetic circuit. Izves7ev and agitolovod armored type, consisting of; t of a rectangular stainless steel yarium tape in a contour rod lined from plast stele pressed into the yario due to deforia (application Fravtsvv K 2290007, CLN 3 / 00,197bg,), The reliability of the connection part assemblies Also known is the magnetic circuit of the induction apparatus, containing two 17-shaped twisted elements made of electrical steel tape and one 1-shaped part made of electrical atal plates (Swiss patent. 628180, kp. HOIF 27/24, 1982). It is known the magnetic circuit (U-shaped elements are located on 2 -X sides of the 1-shaped part and are fastened between them by welded 1 seams .. This design of the magnetic circuit is more reliable than the one described above, but it is not technologically advanced and has an increased complexity of manufacturing. To eliminate the indicated drawbacks in the magnetic circuit of the induction apparatus, containing two / -shaped twisted elements made of electrical steel tape and one of the first part of

- / plates of electro-technical steel, {/ -shaped elements are composed in the 111-shaped part of the magnetic circuit so that. two combined rectilinear parts (Y-shaped elements form the central rod, the other two form the lateral yokes, the middle curvilinear ones form the upper end yoke, and the 1-shaped part closes the aart jjiscae ends of the / -shaped elements, forming the end lower yoke of the magnetic circuit.

In FIG. I presents an example of the construction of a magnetic circuit for transform, torus, in FIG. 2 - for a reactor with an air gap.

The magnetic core consists of a 1-shaped part that performs the function of the lower yoke, lined from a rectangle My tin, and two-shaped elements -,. , half of the cut twisted magnetic circuit wound from stainless steel, with those left in the U-shaped part. In this case, two combined rectilinear ones: sections 2 and 3 form the central core of the magnetic circuit, the other two

4 and 5-side yokes, and the middle curved b and 7 - end upper yoke.

1-shaped and / -shaped elements are interconnected for example, using welds 8 and 9.

For the reactor magnetic circuit between the (/ -shaped elements and the 1-shaped element, there is an air gap 10 formed by a cutout on the inner side of the plates of the 1-shaped part.

, Sone-C r (Log.,

This magnet about the wire Ka e e f f0H, is simple to manufacture, since it has a minimum of 1 quintuple, a non-magnetic gap is formed in the pressure pipe due to stamping of the 1-shaped part at the edge of the plate when cutting them, and the wedging (expansion) of the winding, .- with the help of the introduction of ALL one wedge from above.
