Abstract
The utility model discloses a transformer iron core pulling plate structure. The iron core pulling plate structure comprises two same elongated main plates which are low magnetic steel plates. The iron core pulling plate structure is characterized in that the iron core pulling plate structure is formed by placing the two main plates side by side, arranging a gap between the two main plates, and welding portions of two ends of the two main plates which are located between the two main plates. By adopting the above-mentioned technical scheme, the original process of straight slot milling performed in the middle of a pulling plate is not needed, processing time is reduced, consumption quantity of milling cutters is greatly reduced, the cost is reduced, large deformation caused by uneven heating in the process of straight slot milling is avoided, and requirements of mechanical strength are satisfied at the same time.
Description
Technical field
The utility model relates to the accessory of transformer, particularly a kind of transformer core arm-tie.
Background technology
The high-power transformer iron core all adopts pulling plate structure.Because the axial force that the weight of device body and winding produced owing to secondary circuit short-circuit when arm-tie will bear lifting, so the mechanical strength of arm-tie must be reliably guaranteed.Simultaneously, because arm-tie is in the high leakage field district of transformer, concerning high-power transformer, the leakage flux density on iron core surface can reach 0.05T～0.1T, so the leakage flux that considered reduces perpendicular to the arm-tie surface produces eddy current loss in arm-tie as far as possible.In Fig. 1, the transformer core pulling plate structure of prior art adopts the low magnetic steel plate to be made, and has offered groove on the arm-tie, to lower loss, can avoid the local overheating of arm-tie itself simultaneously.Because the characteristic of low magnetic steel plate, the difficulty that groove is opened at the arm-tie middle part is quite big.Every processing is about 1.5 meters notch together, about 8 hours, on average processes an arm-tie and will scrap a milling cutter in the time of need taking a lot of work; Long processing time in addition, is being opened groove when milling; Inhomogeneous if be heated, arm-tie is easy to generate serious deformation, influences serviceability.
The utility model content
The purpose of the utility model just provides a kind of transformer core pulling plate structure, and it has easy to make, process time of short, low cost and other advantages.
The purpose of the utility model is to realize through such technical scheme, and a kind of transformer core pulling plate structure comprises the mainboard of two blocks of identical rectangular low magnetic steel plates, it is characterized in that two mainboards place side by side, and is provided with the gap therebetween, and the two ends between two mainboards are welded.The technical scheme of the utility model has been saved groove and opened the technology of milling, and has simplified technology, shortens process time widely, and is easy to make.
During practical implementation, the two ends between two mainboards are welded with stiffener, are provided with the hanging axis hole in the middle of the stiffener.
During practical implementation, the bilateral symmetry of stiffener is provided with screwed hole.Because after the two ends welded gaps weldering between two mainboards was full, thread mill drilling had certain degree of difficulty, thus make two into by original one, and along arm-tie center line symmetry.
The beneficial effect of the utility model is: owing to adopted technique scheme; Groove is not opened the technology of milling in the middle of not needing original arm-tie; Reduce machining period, reduced the expense amount of milling cutter widely, reduced cost; Avoided satisfying the requirement of mechanical strength simultaneously because groove is opened the inhomogeneous moderate finite deformation that causes that is heated when milling.
Description of drawings
Below in conjunction with accompanying drawing and embodiment utility model is further specified.
Fig. 1 is the prior art constructions sketch map.
Fig. 2 is the structural representation of the utility model embodiment.
Among the figure: 1, mainboard 2, gap 3, stiffener 4, hanging axis hole 5, screwed hole 6, weld seam.
Embodiment is done the explanation of further indefiniteness to the utility model below in conjunction with accompanying drawing and embodiment: as scheme shown in Figure 2; A kind of transformer core pulling plate structure comprises that 1, two mainboard 1 of mainboard of two blocks of identical rectangular low magnetic steel plates is placed side by side; Be provided with gap 2 therebetween; The two ends that two mainboards are 1 are welded, and the two ends that the two ends welding that two mainboards are 1 forms 1 of 6, two mainboard of weld seam are welded with stiffener 3; Be provided with hanging axis hole 4 in the middle of the stiffener 3, the bilateral symmetry of stiffener is provided with screwed hole 5.Owing to adopted technique scheme, do not need the middle groove of original arm-tie to open the technology of milling, reduced machining period; Reduce the expense amount of milling cutter widely; Reduced cost, avoided satisfying the requirement of mechanical strength simultaneously because groove is opened the inhomogeneous moderate finite deformation that causes that is heated when milling.
At last, it is also to be noted that what more than enumerate only is the specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive from the disclosed content of the utility model or associate all should be thought the protection range of the utility model.
