Abstract

The utility model discloses a low capacity three -phase transformer's structure unshakable in one's determination, include: body unshakable in one's determination, body unshakable in one's determination is the assembly of I type structure and E type structure, the body unshakable in one's determination of E type structure is emptys the state and places, two openings of body unshakable in one's determination of E type structure up, the body unshakable in one's determination of I type structure also is emptys the state and places be " ware " form on two openings of body unshakable in one's determination of E type structure, the peripheral four corners of assembly of I type structure and E type structure is the radius angle. In this way, the utility model discloses can reduce weight to reduce manufacturing cost.

Description

The core construction of low capacity three-phase transformer

Technical field

The utility model relates to transformer technology field, particularly relates to a kind of core construction of low capacity three-phase transformer.

Background technology

At present, the Dou Shi right angle, four angles, lamination four sides of conventional low capacity three-phase transformer, some occasion to the weight of transformer and cost requirement very strict, but in order to the performance that ensures transformer and overall dimension, be difficult to the weight reducing transformer, therefore to the research of Core Structure in Three-Phase Transformers, seem very necessary.

Utility model content

The technical problem that the utility model mainly solves is to provide a kind of core construction of low capacity three-phase transformer, can reduce weight, and reduce manufacturing cost.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the core construction providing a kind of low capacity three-phase transformer, comprise: body unshakable in one's determination, described body unshakable in one's determination is the assembly of I type structure and E type structure, the body unshakable in one's determination of described E type structure is that tilt state is placed, the body unshakable in one's determination two of described E type structure is opening up, in " ware " shape on the body unshakable in one's determination of described I type structure is also placed on E type structure body unshakable in one's determination two openings in tilt state, the peripheral corner of assembly of described I type structure and E type structure is rounding.

In the utility model preferred embodiment, the body length unshakable in one's determination of described I type structure is equal with the body length unshakable in one's determination of E type structure.

The beneficial effects of the utility model are: the utility model is by changing structure unshakable in one's determination, the transformer weight reduction of low capacity is significantly improved, the EI silicon steel sheet simultaneously adopted can be changed on existing mold, conveniently carries out standardization, mass, reduces costs.

Accompanying drawing explanation

Fig. 1 is the structural representation of the core construction of the utility model low capacity three-phase transformer;

Fig. 2 is the Electromagnetic Simulation magnetic circuit of the utility model iron core.

In accompanying drawing, the mark of each parts is as follows: 1, body unshakable in one's determination; 2, rounding; 10, I type structure; 11, E type structure.

Embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection range of the present utility model.

Refer to Fig. 1, the utility model embodiment comprises: a kind of core construction of low capacity three-phase transformer, comprise: body 1 unshakable in one's determination, described body unshakable in one's determination 1 is the assembly of I type structure 10 and E type structure 11, the body unshakable in one's determination of described E type structure 11 is that tilt state is placed, the body unshakable in one's determination two of described E type structure 11 is opening up, in " ware " shape on the body unshakable in one's determination of described I type structure 10 is also placed on E type structure 11 body unshakable in one's determination two openings in tilt state, the peripheral corner of assembly of described I type structure 10 and E type structure 11 is rounding 2.

Furtherly, the body length unshakable in one's determination of described I type structure 10 is equal with the body length unshakable in one's determination of E type structure 11.

Detect according to the electromagnetic magnetic circuit of transformer, the trend of magnetic flux be level and smooth, cannot suddenly change, can think that four outer corners unshakable in one's determination in the utility model do not have magnetic flux and pass through, effect on magnetic circuit is almost nil, this point is demonstrated by electromagnetism simulation software in Fig. 2, therefore carrying out structural optimization to four outer corners of transformer core, is feasible technically.

The core construction of the utility model low capacity three-phase transformer is different from prior art, body separation design unshakable in one's determination, mould mass production can be carried out, be oblique angle or fillet by silicon steel sheet right-angle design, this body weight unshakable in one's determination can be alleviated, carry out standardization, mass production, reduce cost of goods manufactured simultaneously.

The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
