Description
Technical field
The present invention relates to transformer device structure, be specifically related to a kind of transformer pulling plate.
Background technology
Existing transformer pulling plate is connected by bearing pin with folder, is i.e. equipped with a through hole, pin welding on arm-tie and folder
In the upper and lower two through hole of arm-tie, the through hole of folder is connected with unshakable in one's determination, arm-tie by pin, constitutes the skeleton of transformator.This
When attachment structure has the disadvantage that suit coil, first pull down upper clamping piece and upper yoke unshakable in one's determination, then suit coil, due to arm-tie
Pin occupies the suit distance of coil, so causing low-voltage coil suit difficulty.It is that a kind of existing dry type becomes as illustrated in fig. 1 and 2
The pulling plate structure of depressor, respectively bores holes at steel plate upper and lower end, the round pin of corresponding size of burn-oning at upper and lower stomidium.
The transformer pulling plate weight of transformer body to be born and winding secondary circuit short-circuit and axle of producing when lifting
Xiang Li, so the mechanical strength of arm-tie must be reliably guaranteed, the position in the deformation of arm-tie to be prevented and fore-and-aft direction
Move.
Summary of the invention
Goal of the invention: the problem existed for prior art, the present invention provides a kind of transformer pulling plate, this pulling plate structure letter
Easily, easy to assembly, arm-tie is connected by arc structure is embedded with folder, and circular shape has from limit function, and restriction is drawn
The displacement of plate above-below direction, the support plate on folder is possible to prevent deformation and the front and back that arm-tie length direction outwards arches upward simultaneously
Displacement upwards.
Technical scheme: in order to realize foregoing invention purpose, as described in the present invention a kind of transformer pulling plate, including arm-tie,
Support plate on folder and folder, described folder is divided into upper clamping piece and lower clamping piece, the both ends of described arm-tie to be circular shape, institute
State the end of upper clamping piece and lower clamping piece to be provided with and coordinate the arc groove that can embed circular shape with arm-tie end.
Further, described support plate is welded in the end of arc groove of upper clamping piece and lower clamping piece.It is welded on upper and lower folder
Support plate displacement in the transformator lifting deformation outwards arched upward of limit arm-tie length direction and fore-and-aft direction, thus
Guarantee the lifting safety of transformator.
Further, described upper clamping piece and lower clamping piece coordinate with arm-tie, and arm-tie both ends are respectively embedded into upper clamping piece and lower folder
Part, and coordinate face concordant, and ensure certain fit dimension.During closed assembly unshakable in one's determination, upper and lower folder coordinates with arm-tie,
The cooperation face of asking is concordant.The weight of device body when bearing lifting is played in cooperation face.
Further, the middle milling of described arm-tie becomes kidney slot.Arm-tie opens kidney slot to reduce loss, the most permissible
Avoid the hot-spot of arm-tie itself.
Further, described arm-tie and folder are in a plane.This pulling plate structure, because arm-tie and folder are in a plane,
Reduce the consumption of apparatus for fixing transformer insulation；Arm-tie before improvement, folder is placed in the outside of arm-tie, so the thickness of clamp insulation
Want the gauge of many arm-ties.
Further, after described arm-tie both ends are respectively embedded into upper clamping piece and lower clamping piece with bandage by arm-tie and upper clamping piece and
Lower clamping piece is fixed.
Beneficial effect: compared by prior art, a kind of transformer pulling plate of the present invention has the advantage that arm-tie and folder
Connection be connected with before and after folder by round pin by original, be advanced through that arc structure is embedded with folder to be connected, and circle
Arc shape has from limit function, limits the displacement of arm-tie above-below direction；Be welded in transformer pulling plate on upper and lower folder props up
The deformation that plate outwards arches upward for transformator lifting limit arm-tie length direction, and the displacement on arm-tie fore-and-aft direction, from
And guarantee the lifting safety of transformator；The transformer pulling plate of the present invention is during closed assembly unshakable in one's determination, and upper and lower folder is last and arm-tie
Coordinate, it is desirable to coordinating face concordant, the weight of device body when bearing lifting is played in cooperation face；Arm-tie and folder are in a plane simultaneously, fall
The consumption of low apparatus for fixing transformer insulation；Processing technique of the present invention is simple, simple structure, easy to assembly.

Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
Embodiment 1
As in Figure 3-5, a kind of transformer pulling plate, including arm-tie (1), it is divided into upper clamping piece (2), the folder of lower clamping piece (5)
And the support plate (5) on folder from top to bottom；The both ends of arm-tie (1) are circular shape, simultaneously at upper clamping piece (2), lower clamping piece (4)
The end of arc groove processes the size that coordinate corresponding to arm-tie end, can embed circular shape arc groove, upper clamping piece (2)
Coordinating with arm-tie (1) with lower clamping piece (4), arm-tie (1) can interlock with folder from top to bottom, and coordinates face concordant, and cooperation face is played and held
By the weight of device body when lifting by crane；The support plate (3) being welded in the end of arc groove on upper and lower folder prevented when transformator lifts by crane
Displacement in deformation that arm-tie length direction outwards arches upward and fore-and-aft direction, so that it is guaranteed that the lifting safety of transformator.
The middle milling of arm-tie (1) becomes kidney slot, owing to arm-tie (1) is in the high leakage field district of transformator, to Large Copacity transformation
For device, the leakage magnetic flux density on surface unshakable in one's determination, up to 0.05T～0.1T, is perpendicular to arm-tie (1) surface so should reduce as far as possible
The eddy-current loss that leakage magnetic flux produces in arm-tie, opens kidney slot to reduce loss on arm-tie (1), can avoid arm-tie simultaneously
(1) hot-spot of itself；, arm-tie (1) both ends be respectively embedded into after upper clamping piece (2) and lower clamping piece (4) with bandage by arm-tie with
Folder is fixed, and this arm-tie (1) and folder, in a plane, reduce the consumption of apparatus for fixing transformer insulation；Existing draw before improving
Plate, folder is placed in the outside of arm-tie, so the thickness of clamp insulation wants the gauge of many arm-ties.
This pulling plate structure processing technique is simple, and design concept is novel, simplifies the course of processing on the whole, clamper for iron core standing,
Winding compresses and in device body moving process, uses the transformator of the present embodiment arm-tie that abnormal conditions do not occur.Meet machinery strong
The requirement of degree.
