Description

Ring-type three-phase transformer

The utility model relates to three-phase transformer, is a kind of ring-type three-phase transformer.

Existing ring-type three-phase transformer generally comprises iron core and coil windings, with regard to each a kind of three-phase transformer is disclosed for CN2226798Y and CN2332048Y as patent announcement number, their iron core all is made up of the monocycle iron core of three rectangles, the rectangular edges of per two monocycle iron cores is held together, as an iron core column, form three iron core column altogether.Because each iron core column is made up of the rectangular edges of two monocycle iron cores, in bind, have bigger space, thereby cause the magnetic consumption to make energy consumption higher greatly, and noise is bigger; Simultaneously, because iron core seals, cause trouble to coiling, thereby influence production efficiency.

In view of the problem of above-mentioned existence, the ring-type three-phase transformer that the purpose of this utility model is to design a kind of simple in structure, good energy-conserving effect, is convenient to make.

The purpose of this utility model realizes by following measure: this ring-type three-phase transformer comprises iron core and coil windings, and iron core comprises iron core column, upper yoke and lower yoke, coil windings is installed on iron core column, and the upper end of three iron core column is fixedly mounted on respectively on the upper yoke of ring-type, and the lower end of three iron core column is fixedly mounted on respectively on the lower yoke of ring-type.

Above-mentioned upper yoke is or/and lower yoke can be leg-of-mutton.

Three above-mentioned iron core column are fixedly mounted on upper yoke respectively or/and three top corner parts of lower yoke make three iron core column constitute three ribs of triangular prism.

The cylinder that above-mentioned iron core column adopts amorphous alloy material or silicon steel sheet to turn to; Perhaps iron core column adopts the cylinder that amorphous alloy material or silicon steel sheet concentric circles jacket casing are made.

Above-mentioned upper yoke is or/and the triangle ring bodies that lower yoke adopts amorphous alloy material or silicon steel sheet to turn to; Perhaps upper yoke is or/and the triangle ring bodies that lower yoke Bian makes with amorphous alloy material or silicon steel sheet concentric locking collar.

Above-mentioned iron core column and upper yoke or/and the contact-making surface of lower yoke be the plane or curved surface.

Above-mentioned iron core column is fixedly mounted on upper yoke or/and lower yoke by the magnetism molecule binder.

Accompanying drawing 2 is the plan structure schematic diagram of accompanying drawing 1,

Accompanying drawing 3 is the main TV structure schematic diagram of iron core column in the accompanying drawing 1,

Accompanying drawing 4 is the plan structure schematic diagram of accompanying drawing 3,

Accompanying drawing 5 is the perspective view of accompanying drawing 1,

Coding in the accompanying drawing is respectively: 1 is iron core column, and 2 is upper yoke, and 3 is coil windings, and 4 is lower yoke.

Below in conjunction with most preferred embodiment and accompanying drawing the utility model is further described:

Shown in accompanying

drawing

1,2 and 5, this ring-type three-phase transformer comprises iron core and coil windings 3, and iron core comprises iron core column 1, upper yoke 2 and lower yoke 4, coil windings 3 is installed on iron core column 1, and the upper end of three iron core column 1 is fixedly mounted on respectively on the upper yoke 2 of ring-type, and the lower end of three iron core column 1 is fixedly mounted on respectively on the lower yoke 4 of ring-type.Like this when making the utility model, make earlier iron core column 1, upper yoke 2 and lower yoke 4 respectively, secondly coil windings 3 is installed on the iron core column 1, there is the iron core column 1 of coil windings 3 to be fixedly mounted on upper yoke 2 and the lower yoke 4 with three then, thereby make the utility model simple in structure and be convenient to make,, thereby reduced the magnetic consumption because iron core column is as a whole, thereby energy-saving effect is preferably arranged, and greatly reduce noise.

Shown in accompanying drawing 2 and 5, upper yoke 2 and lower yoke 4 are preferably leg-of-mutton, but also can be according to actual needs, upper yoke 2 or lower yoke 4 are leg-of-mutton, also can be according to actual needs with upper yoke 2 or/and lower yoke 4 is made other shape, and three iron core column 1 are fixedly mounted on upper yoke 2 respectively or/and three top corner parts of lower yoke 4 make three iron core column 1 constitute three ribs of triangular prism.

In order further to improve performance of the present utility model, shown in accompanying drawing 2 to 5, the cylinder that iron core column 1 preferably adopts amorphous alloy material or silicon steel sheet to turn to; Perhaps iron core column 1 adopts the cylinder that amorphous alloy material or silicon steel sheet concentric circles jacket casing are made; And upper yoke 2 is or/and the triangle ring-type that lower yoke 4 also preferably adopts amorphous alloy material or silicon steel sheet to turn to; Perhaps upper yoke 2 is or/and the triangle ring bodies that lower yoke 4 adopts amorphous alloy material or silicon steel sheet concentric locking collar to make.

In the utility model, iron core column 1 with upper yoke 2 or/and the contact-making surface of lower yoke 4 can be according to actual needs the plane or curved surface, be installed on upper yoke 2 and the lower yoke 4 so that iron core column 1 firmly fixed, and iron core column 1 preferably is fixedly mounted on upper yoke 2 by the magnetism molecule binder or/and on the lower yoke 4, thereby further reduces magnetic loss.

Shown in accompanying drawing 1 to 5, above-mentioned technical characterictic has constituted the utility model illustrated embodiments, and can increase and decrease above-mentioned non-essential technical characterictic according to actual needs.

The utility model is simple in structure, and cost is saved in the material saving, and is easy and simple to handle, is convenient to make, and is unloaded, load loss is little, and energy-saving effect is obvious.
