The full face type pulling plate and clamping piece structure comprises an upper clamping piece, a lower clamping piece and a pulling plate, wherein cross sections of the upper clamping piece and the lower clamping piece have a groove shape; both ends of the pulling plate are provided with chucks; the webs of the upper clamping piece and the lower clamping piece are provided with troughs of which the shapes are matched with those of the chucks; the chucks are clamped on the rear side of the troughs; and the pulling plate, the upper clamping piece and the lower clamping piece are stuck on the same plane of the iron core. In the full face type pulling plate and clamping piece structure, both ends of the pulling plate are provided with the chucks, both ends of the pulling plate are clamped in the troughs of the upper clamping piece and the lower clamping piece in an inlaying way, and the pulling plate, the upper clamping piece and the lower clamping piece are stuck on the same plane of the iron core, so that the contact surface of the clamping pieces and the iron core is more smooth, and a bundling effect on the iron core is relatively good, and the difficulty in processing an insulating material filled in the center of the iron core is reduced. The full face type pulling plate and clamping piece structure is easy to assemble and has high iron core assembly efficiency.
Description
Technical field
The present invention relates to transformer, specifically a kind of whole plane formula arm-tie folder structure that is used for transformer core.
Background technology
In transformer, core clamping plays and clamps the electrical steel sheet, forms transformer internal magnetic field loop, serves as the inner effect that skeleton is installed of transformer.
Existing core clamping mainly comprises upper clamping piece, lower clamping piece and connects the arm-tie of upper clamping piece and lower clamping piece, upper clamping piece and lower clamping piece are many to be made with the section bar channel-section steel, have location hole on upper clamping piece and lower clamping piece, be provided with positioning key at the two ends of arm-tie, positioning key is fixed in the location hole.There is the thickness gap of an arm-tie in this syndeton complex structure between arm-tie and electrical steel sheet contact-making surface and the folder, this gap must be with insulating part pad, structural instability; The difficulty of processing of insulating part is big, processes improperly, will unbalance stress between iron core, arm-tie, the folder, and folder is unstable, thereby brings the influence of noise and loss.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of stressed even, constitutionally stable whole plane formula arm-tie folder structure is provided.
According to technical scheme of the present invention: a kind of whole plane formula arm-tie folder structure, comprise upper clamping piece, lower clamping piece and arm-tie, the cross section of described upper clamping piece and described lower clamping piece is a flute profile, the two ends of described arm-tie are provided with dop, have the draw-in groove that is complementary with described dop shape on the web of described upper clamping piece and described lower clamping piece, after described dop was connected in described draw-in groove, described arm-tie and described upper clamping piece and described lower clamping piece were affixed on the same plane unshakable in one's determination.
Described dop and described draw-in groove be shaped as T shape.
The both sides at described arm-tie two ends have the breach of symmetry, and the end of described breach and described arm-tie forms described dop.
Described breach is trapezoidal.
Described upper clamping piece and described lower clamping piece are formed by the steel plate flanging.
The width of the bottom wing listrium of described upper clamping piece is greater than the width of its top flange plate, and the width of the top flange plate of described lower clamping piece is greater than the width of its bottom wing listrium.
Have vertical elongated slot on the described arm-tie.
Described arm-tie has three, has three described draw-in grooves on described upper clamping piece and the described lower clamping piece.
Technique effect of the present invention is: the present invention is provided with dop at the two ends of arm-tie, the dop at arm-tie two ends adopts the mode of inlaying to be connected in the draw-in groove of upper clamping piece and lower clamping piece, arm-tie and upper clamping piece and lower clamping piece are affixed on the same plane unshakable in one's determination, make folder more steady to the contact-making surface of iron core, better to the bundle folder effect of iron core; Reduced the difficulty of processing of the insulating material of middle filling usefulness.The present invention assembles simply, efficiency of assembling height unshakable in one's determination.

Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described.
Among Fig. 1 ~ Fig. 8, comprise draw-in groove 1, lower clamping piece 2, upper clamping piece 3, dop 4, arm-tie 5, iron core 6, elongated slot 7, breach 8 etc.
As shown in Figure 1, the present invention is a kind of whole plane formula arm-tie folder structure, and stem unshakable in one's determination is axially reinforced, and laminated core is clamped reinforce into a magnetic circuit integral body, preventing that yoke seam up and down unshakable in one's determination is stressed brings damage for seam crossing unshakable in one's determination, thereby influences the increase of core loss.It comprises upper clamping piece 3, lower clamping piece 2 and arm-tie 5.Arm-tie 5 has three.
As Fig. 2～shown in Figure 4, the cross section of lower clamping piece 2 is a flute profile, is formed by the steel plate flanging, and the width of its top flange plate is greater than the width of its bottom wing listrium.The web top edge of lower clamping piece 2 has three draw-in grooves 1 that are shaped as T shape.
As Fig. 5～shown in Figure 7, the cross section of upper clamping piece 3 also is a flute profile, is formed by the steel plate flanging.Upper clamping piece 3 and lower clamping piece 2 symmetries, the width of the bottom wing listrium of upper clamping piece 3 is greater than the width of its top flange plate.The web lower limb of upper clamping piece 3 also has three draw-in grooves 1 that are shaped as T shape.Draw-in groove 1 can form by laser cutting.
As shown in Figure 8, arm-tie 5 is the strip flat board, and the both sides at its two ends have the breach 8 of symmetry, and breach 8 is preferably trapezoidal, can certainly be other shape, such as rectangle or semicircle.The end of breach 8 and arm-tie 5 forms the dop 4 of T shape, and dop 4 is complementary with the shape of draw-in groove 1, forms male and female and cooperates.Also have vertical elongated slot 7 on the arm-tie 5, can reduce eddy current loss.
Again referring to Fig. 1, after the dop 4 at arm-tie 5 two ends is connected in the draw-in groove 1 of upper clamping piece 3 and lower clamping piece 2, dop 4 is embedded in the draw-in groove 1, arm-tie 5 is affixed on the same plane of iron core 6 with upper clamping piece 3 and lower clamping piece 2, solved traditional folder effectively to the unstable situation of iron core pressurization, make folder more steady to unshakable in one's determination 6 contact-making surface, better to unshakable in one's determination 6 bundle folder effect; Reduced the difficulty of processing of the insulating material of middle filling usefulness, middle insulating part processing becomes simpler, easy operating, and this structure is to the better adaptability of the insulating material of centre filling.
The present invention assembles simply, and efficiency of assembling height unshakable in one's determination has been stopped the phenomenon of doing over again.
