Description
Technical field
The utility model relates to a kind of core structure of the three-dimensional reel iron core transformer with arm-tie, belongs to iron core technical field.
Background technology
At present, pulling plate structure is adopted in a large number in laminated structure, and also no one's application in of the same trade in volume core construction.Stage now, three dimensional wound core is all the screw-rod structure that draws adopting, on upper frame and underframe, be all welded with Zhi Tie, during assembling unshakable in one's determination, at Zhi Tiezhong, through drawing screw rod that transformer body is fastening, three dimensional wound core coil is isosceles triangle to be arranged, triangular in shape in vertical view, generally every limit arranges that one draws screw rod, counts three.We find that in production reality this draws screw-rod structure to have following improper part: one, relatively jumbo transformer, during short circuit, the impulsive force of coil is larger, three are drawn screw rod to show slightly thin, we also must respectively increase by one in three bights and draw screw rod, and this has brought difficulty just to the high and low pressure lead-in wire assembling of transformer; Two, all screw rods that draw, all in the outside of transformer body, make transformer profile tight not rapid, attractive in appearance not, also inconvenience transportation; Three, for the dry-type transformer of 20kV or 35kV, owing to drawing screw rod to follow the electrical distance of high-voltage connection too small and often breakdown, affect the safe operation of transformer.
Summary of the invention
Technical problem to be solved in the utility model is the defect that overcomes prior art, a kind of core structure of the three-dimensional reel iron core transformer with arm-tie is provided, it can effectively guarantee transformer tightening force, improve transformer anti-short circuit capability, effectively improve the electrical distance of high-voltage connection in the high voltage situation of 20kv or 35kv, make product compactness and good looking appearance.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of core structure of the three-dimensional reel iron core transformer with arm-tie, comprise upper frame, underframe and three iron core frames, the angle assembling combination that three iron core frames are pressed 120 °, central angle together, the assembled position of adjacent iron core frame forms stem stem, two arm-ties are all installed on each iron core frame, and two arm-ties on each iron core frame are the symmetrical structure with the axis of this iron core frame, in adjacent iron core frame, two adjacent arm-ties are tied up on stem stem by bandage, and two arm-ties on each stem stem are the symmetrical structure with the stitching position of adjacent iron core frame, the upper end of six arm-ties is all connected with upper frame by stud pin, the lower end of six arm-ties is all connected with underframe by stud pin.
Further, between the upper end of described arm-tie and the contact site of upper frame, be provided with attached pad, between the lower end of described arm-tie and the contact site of underframe, be also provided with attached pad.
Further, in order to guarantee the low permeance of attached pad, described attached pad is made by stainless steel material.
Further, in order to guarantee the low permeance of arm-tie, described arm-tie is made by stainless steel material.
Further for convenient coiling on stem stem, and can be reserved with the position that arm-tie is installed, on described stem stem and this stem stem, the outline of the cross section of two corresponding arm-ties is positioned on same circumference.
Adopted after technique scheme, six arm-ties of the present utility model are tied up on stem stem by bandage, and adopt stud pin that the upper end of six arm-ties and upper frame are coupled together, adopt stud pin that the lower end of six arm-ties and underframe are coupled together, the axial force that transformer is experienced is delivered on arm-tie by stud pin, so just the requirement of transformer body to tightening force be can guarantee completely, and product compactness and good looking appearance made; In addition, because arm-tie is tied up on stem stem, like this, the electrical distance of arm-tie and high-voltage connection is unlikely to too small, thereby avoids breakdown phenomenon.
