Abstract

The utility model relates to a silicon steel band combined wound single-phase transformer iron core, which is composed of a main iron core and an auxiliary iron core. The main iron core is formed by that two rectangular or semicircle sectional silicon steel band wound iron cores are combined together, and the auxiliary iron core is formed by that silicon steel bands whose layer number is less than the layer number of each iron core of the layer number main iron core are wound around from an auxiliary iron core. Because of the effect of the auxiliary iron core, the magnetic leakage of a transformer can be reduced, the magnetic conductivity of a transformer can be enhanced, the structure of the utility model is simple, the mass production of the transformers which are provided with miniature Winded iron cores can be realized, and the casing type iron core of the single phase transformer of the integration of the section of a cylinder can be produced.

Description

The compound coiling single-phase transformer of silicon strip iron core

The utility model relates to a kind of silicon strip coiling single-phase transformer iron core.

Electronics industry ministerial standard SJ103-77 single-phase transformer is formed by being equivalent to two C sections cores with ED type C sections core (shell-type), such iron core is when the manufacturing of miniature transformer, iron core production is difficulty relatively, and it is made up of four joints simultaneously, and is convenient inadequately during use; The profile of R sections core and CD sections core is close, and just its core section is a garden shape, and it can not make the iron core of whole shell-type single-phase transformer.

The purpose of this utility model is exactly the iron core of a kind of new structure of providing at the weak point on the above-mentioned core structure, can manufacture the single-phase transformer Wound core of miniature single-phase transformer Wound core and whole garden tee section, and is applied widely.

The technical solution of the utility model is: be made up of main iron core and auxiliary iron core, wherein lump together and constitute main iron core by the silicon steel roll coil of strip iron core group of two rectangles or semi-circular cross-section, silicon strip constitutes auxiliary iron core on the coiling of the periphery of main iron core, and the silicon strip number of plies of auxiliary iron core is less than the silicon strip number of plies of every iron core of main iron core.

Just become one pair of single-phase transformer shell type core after the iron core process iron core procedure processing according to the technique scheme formation,, can be cut into two sections uses, also can not cut off and do as a whole use according to instructions for use.

The compound coiling single-phase transformer of the silicon strip that the utility model provides iron core, because the effect of auxiliary iron core, can reduce the leakage field of transformer, improve the magnetic property of transformer, simple in structure, can produce miniature Wound core transformer in enormous quantities, the shell type core of the single-phase transformer of integral body that can the production cylindrical cross-section, applied widely.

Below in conjunction with the embodiment accompanying drawing in detail the utility model is described in detail.

At first accompanying drawing is described:

Figure one expression structure chart of the present utility model;

The vertical view of figure two presentation graphs one garden tee section silicon strip Wound core;

The vertical view of figure three presentation graphs one square-section silicon strip Wound core.

Referring to figure one, the compound coiling single-phase transformer of silicon strip iron core is to be made of main iron core (1) and auxiliary iron core (2), combine by two silicon strip Wound cores and to constitute main iron core (1), go up silicon strip at the periphery of main iron core (1) coiling and constitute auxiliary iron core (2), wherein the silicon strip number of plies of auxiliary iron core (2) is less than the silicon strip number of plies of every iron core of main iron core (1).When the cross section of every iron core of main iron core (1) when being semicircle, be the shell type core of single-phase transformer of the integral body of cylindrical cross-section, the embodiment shown in figure two.When the cross section of every iron core of main iron core (1) is rectangle, be miniature Wound core transformer, the embodiment shown in figure three.

Claims

1, the compound coiling single-phase transformer of a kind of silicon strip iron core, form by main iron core and auxiliary iron core, it is characterized in that combining and constitute main iron core (1) by the silicon strip Wound core of two rectangles or semi-circular cross-section, go up silicon strip at the periphery of main iron core (1) coiling and constitute auxiliary iron core (2), wherein the silicon strip number of plies of auxiliary iron core (2) is less than the silicon strip number of plies of every iron core of main iron core.
