Description
Technical field
The present invention relates to a kind of transformer three-dimensional winding iron core, for three-phase rewinding material oil-immersed type transformer or dry-type transformer.
Background technology
Conventional stereo rewinding material is combined by three identicals, with the rectangular core frame of continuous silicon steel sheet coiling.
Its defect is that coil must the coiling on finished product core limb, it is necessary to special coil winding machine used, causes investment of production equipment to increase,
Because the limitation reason of equipment also leads to not the transformer of production larger capacity.Because its iron core is completely enclosed, coil
It can not pull down, once coil breaks down, maintenance will be extremely difficult.
At present, also have using opening rewinding material in three dimensional wound core transformer production, but aperture position is all in transformation
On the stem of device, so once it is so difficult again that abutment joint position is handled to be inserted in coil.And seam arrangements cause magnetic resistance
Increase, adds the loss of transformer.
The content of the invention
In order to solve the above technical problems, it is an object of the invention to provide a kind of open type transformer three-dimensional winding iron core.
The object of the present invention is achieved like this：It is made up of three identical iron core frames made of silicon steel sheet, and it is special
Sign is：Each iron core frame surrounds hexagon frame with lower half frame by upper half frame and formed, and described hexagon refers to the two of rectangle frame
Individual upper turning becomes what is formed after chamfering, and it includes the upper left corner and two, upper right corner iron core frame bevel edge；Upper half frame has left and right
Two upper half frame bevel edges, lower half frame have the two lower half frame bevel edges in left and right, the silicon steel sheet of two bevel edges of upper and lower half frame homonymy
In interlaced arrangement, by two bevel edges of homonymy（That is upper half frame bevel edge and lower half frame bevel edge）Silicon steel sheet plug each other one
Rise and form iron core frame bevel edge, every layer of silicon steel sheet connects in the bending part of silicon steel sheet.
In the actual production present invention, first three lower half frames unshakable in one's determination are combined to form three circles or external circular
The core limb of polygon, then it is inserted in transformer coil；Upper and lower half frame unshakable in one's determination is closed to insert group again；Finally, by the silicon of upper ledge unshakable in one's determination
The processing such as fastening of painting is carried out after steel disc arrangement is regular.
Compared with prior art, the positive effect of the present invention is：Its joint location unshakable in one's determination is inserted in completely outside coil
Joint location fastening processing can be very easily carried out after coil, it is highly beneficial to reduce loss to reducing transformer noise for this.
Easily upper half frame unshakable in one's determination can also be removed in the event of failure and extract coil and be repaired.Secondly, the docking of silicon steel sheet
For seam positioned at the bending part of silicon steel sheet, the gap of docking compensate for that there is identical bending fillet to bring is dry due to every layer of silicon steel sheet
Problem is related to, is advantageous to improve the lamination coefficient of silicon steel sheet, makes it possible the three dimensional wound core transformer of production more Large Copacity.Again
It is secondary, interlock because joint location carries out silicon steel sheet in Liang Geshang corners, and corner's self-assembling formation interlocks ladder, and this makes it
Magnetic property closely closes rewinding material.Finally, it has that magnetic circuit is short, and low, the small noise of harmonic wave is lost in the small , Kong Load of exciting current
The features such as low.

The present invention is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the schematic diagram of the present invention.
Fig. 2 is the profile after Fig. 1 is cut by horizontal plane.
Fig. 3 is the schematic diagram that upper and lower half frame is combined into an iron core frame.
Fig. 4 is the lower half frame schematic diagram in Fig. 2.

Embodiment
Referring to Fig. 1, by three identicals, the iron core frame 1 made of silicon steel sheet forms for it, referring to Fig. 3-5, each iron core frame 1
Hexagon frame is surrounded by upper half frame 1.2 with lower half frame 1.1 to form, described hexagon refers to two of rectangle frame upper turnings are equal
Become what is formed after chamfering, it includes the upper left corner and two, upper right corner iron core frame bevel edge 1.4；Upper half frame has two upper half in left and right
Frame bevel edge 1.4.2, lower half frame have the two lower half frame bevel edge 1.4.1 in left and right, the silicon steel of two bevel edges of upper and lower half frame homonymy
Piece is in interlaced arrangement, and the silicon steel sheet of two bevel edges of homonymy is plugged each other and forms iron core frame bevel edge 1.4, every layer of silicon together
The seam 1.3 of steel disc is in the bending part of silicon steel sheet.Lower half frame is that two lower turnings of iron core frame are rounded.
Described chamfering is conventional chamfering, generally 40-50 degree.
Referring to Fig. 2, the section of each iron core frame is the polygon of semicircle or external semicircle.
