Abstract
The invention provides an open type transformer three-dimensional roll-core. The three-dimensional roll-core is characterized in that the roll-core is composed of three identical iron core frames made of silicon steel sheets, and each iron core frame is formed by a hexagonal frame defined by an upper half frame and a lower half frame; the upper half frame is provided with a left and a right upper half frame bevel edge; the lower half frame is provided with a left and a right lower half frame bevel edge; the silicon steel sheets of two bevel edges at the same sides of the upper half frame and the lower half frame are arranged in a staggered manner; the silicon steel sheets of two bevel edges at the same sides are mutually inserted together to form the bevel edges of the iron core frames; the silicon steel sheets of each layer are connected at bending positions of the silicon steel sheets. The open type transformer three-dimensional roll-core has the positive effects that an iron core joint position of the roll-core is completely out of a coil, joint position fastening treatment can be very conveniently carried out after the iron core joint position is sheathed in the coil, and the roll-core is very conducive to transformer noise reduction and loss reduction. If a fault happens, the upper half frame of the iron core frame can be conveniently dismantled and the coil can be pulled out for maintenance.
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 by three identical, combine with the rectangular core frame of continuous print silicon steel sheet coiling.Its defect is that coil must coiling on finished iron stem, and must use special coil winding machine, cause investment of production equipment to strengthen, the limitation reason due to equipment also causes the transformer cannot producing larger capacity.Because its iron core has been totally enclosed, coil cannot be pulled down, once coil breaks down, maintenance will be very difficult.
At present, also have in three dimensional wound core transformer production and adopt opening rewinding material, but aperture position is all on the stem of transformer, like this once be inserted in the so very difficult abutment joint position again of coil and process.And seam arrangements causes magnetic resistance to increase, add the loss of transformer.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is 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 be made up of silicon steel sheet, it is characterized in that: each iron core frame surrounds hexagon frame by first frame and second frame and forms, said hexagon is formed after referring to and two of rectangle frame upper turnings all being become chamfering, and it comprises the upper left corner and two, upper right corner iron core frame bevel edge; First frame has two first frame bevel edges in left and right, second frame has two second frame bevel edges in left and right, the silicon steel sheet of upper and lower half frame homonymy two bevel edges is interlaced arrangement, form iron core frame bevel edge together with being plugged each other by the silicon steel sheet of homonymy two bevel edges (i.e. first frame bevel edge and second frame bevel edge), every layer of silicon steel sheet connects at the bending part of silicon steel sheet.
When actual production is of the present invention, first three second frames of iron core is carried out the polygonal core limb being combined to form three circles or external circle, then be inserted in transformer coil; Again upper and lower for iron core half frame is closed insert group; Finally, after regular for the arrangement of the silicon steel sheet of upper ledge unshakable in one's determination, process such as fastening grade of painting is carried out.
Compared with prior art, good effect of the present invention is: its joint location unshakable in one's determination, completely outside coil, can carry out the fastening process of joint location after being inserted in coil very easily, and this, to reduction transformer noise, reduces the wastage highly beneficial.Keep in repair if break down also can easily first frame unshakable in one's determination be removed and extract coil.Secondly, the abutment joint of silicon steel sheet is positioned at the bending part of silicon steel sheet, the gap of docking compensate for because every layer of silicon steel sheet has the interference problem that identical bending fillet brings, and is conducive to the lamination coefficient improving silicon steel sheet, makes the more jumbo three dimensional wound core transformer of production become possibility.Again, carry out silicon steel sheet and interlock, the ladder and corner's self-assembling formation interlocks due to joint location in Liang Geshang corner, this makes its magnetic property closely closed rewinding material.Finally, it is short that it has magnetic circuit, and exciting current little ， Kong Load loss is low, the features such as the little noise of harmonic wave is low.

Embodiment
See Fig. 1, it is made up of three identical iron core frames 1 be made up of silicon steel sheet, see Fig. 3-5, each iron core frame 1 surrounds hexagon frame by first frame 1.2 with second frame 1.1 and forms, said hexagon is formed after referring to and two of rectangle frame upper turnings all being become chamfering, and it comprises the upper left corner and two, upper right corner iron core frame bevel edge 1.4; First frame has two first frame bevel edge 1.4.2 in left and right, second frame has two second frame bevel edge 1.4.1 in left and right, the silicon steel sheet of upper and lower half frame homonymy two bevel edges is interlaced arrangement, plugged each other by the silicon steel sheet of homonymy two bevel edges and form iron core frame bevel edge 1.4 together, the seam 1.3 of every layer of silicon steel sheet is in the bending part of silicon steel sheet.Two lower turnings of second frame and iron core frame are fillet.
Said chamfering is conventional chamfering, is generally 40-50 degree.
See Fig. 2, the cross section of each iron core frame is polygon that is semicircle or external semicircle.
