Abstract
The utility model discloses an iron core clamping device of a transformer, which comprises symmetrical left and right fixing clamping plates (2 and 2'), an iron core (6) is clamped between the left and right fixing clamping plates (2 and 2'), and two ends of the left and right fixing clamping plates (2 and 2') are fastened and connected with each other by left and right screw groups (5 and 5'); and the iron core clamping device is characterized in that a locking strip (4) is pulled between the left and right fixing clamping plates (2 and 2'). The iron core clamping device of the transformer has the obvious effects of having simple structure, leading to even stress of an iron core, enhancing the laminating effect of silicon-steel plates in the middle of the iron core, and reducing air gaps among the silicon-steel plates as well as magnetic loss in the transformer and noise when the transformer works simultaneously.
Description
Technical field
The utility model belongs to a kind of technical field of transformer manufacturing, particularly relates to a kind of clamping device of transformer core.
Background technology
The iron core of transformer is built up with many silicon steel sheets at present, for guaranteeing that silicon steel sheet can closely be stacked, reduce the air gap between silicon steel sheet to greatest extent, to reduce magnetic loss and the noise in the transformer, for this reason, we adopt the left and right strap of symmetry to compress iron core, iron core is fixed between the left and right clamping plate, and the two ends of left and right strap are fastenedly connected through left and right screw rod group, by the pulling force of screw rod, silicon steel sheet can closely be stacked
The clamping of silicon steel sheet mainly realizes by screw rod.The both sides of transformer core use some groups of other screw rods that folder is connected, by adjusting nut, realized iron core is clamped, but this clamping mode can only push the silicon steel sheet at tension two ends, and the screw rod pulling force minimum that the silicon steel sheet at iron core middle part is subjected to.
The shortcoming of prior art is: the discontinuity of iron core, and the superimposed weak effect of iron core middle part silicon steel sheet, the air gap between silicon steel sheet is big, and the magnetic loss in the transformer is still higher, simultaneously, the noise when also having increased transformer work.
The utility model content
Problem to be solved in the utility model is to provide a kind of transformer core clamping device, and the air gap that can effectively control between the silicon steel sheet of iron core middle part is big, the noise when reducing transformer work.
For achieving the above object, the utility model is providing a kind of transformer core clamping device, the left and right strap that comprises symmetry, clamping is cored between this left and right strap, the two ends of left and right strap are fastenedly connected through left and right screw rod group, and its key is: drawn locking strip between the described left and right strap.
Except two ends, also,, can guarantee effectively that also the silicon steel sheet of iron core central region can closely be superimposed together even iron core is long again by the central region of locking strip tension iron core by left and right screw rod group tension iron core.
Described locking strip comprises iron bar, is enclosed with the insulation gum cover on this iron bar, and the two ends of iron bar are welded with screw rod, and this screw rod stretches out the insulation gum cover, and is fixed on the described left and right strap.
Be respectively arranged with the left and right journal stirrup of symmetry on the described left and right strap, have through hole on the described left and right journal stirrup, the screw rod of described locking strip passes this through hole, and the cover loading nut is fixed.
By the left and right screw rod group of installing on the left and right strap, the iron core two ends are clamped, the locking strip two ends strain at left and right strap simultaneously, by the left and right nut that rotational lock bar two ends are provided with, just can clamp the iron core middle part, many group locking strips can be installed between left and right strap, locking strip makes iron core stressed evenly, fit tightly, noise is little when making transformer work, moves more stable.
Remarkable result of the present utility model is: simple in structure, the stressed of iron core evenly strengthened the superimposed effect of iron core middle part silicon steel sheet, reduced the air gap between silicon steel sheet, reduced the magnetic loss in the transformer, simultaneously, and the noise when also having reduced transformer work.
Description of drawings
Fig. 1 is that the transformer core installation concerns schematic diagram;
Fig. 2 is an iron core locking device scheme of installation.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1, 2, a kind of transformer core clamping device, the left and right strap 2 that comprises symmetry, 2 ', this left and right strap 2, clamping cored 6 between 2 ', left and right strap 2,2 ' two ends are fastenedly connected through left and right screw rod group 5,5 ', and described left and right strap 2 has also drawn locking strip 4 between 2 '.
Described locking strip 4 comprises iron bar, is enclosed with the insulation gum cover on this iron bar, and the two ends of iron bar are welded with screw rod, and this screw rod stretches out the insulation gum cover, and is fixed on the described left and right strap 2,2 '.
Be respectively arranged with the left and right journal stirrup 3,3 ' of symmetry on the described left and right strap 2,2 ', have through hole on the described left and right journal stirrup 3,3 ', the screw rod of described locking strip 4 passes this through hole, and the cover loading nut is fixed.
Operation principle of the present utility model is:
By left and right strap 2,2 ' goes up the left and right bolt group 5,5 ' of installing, iron core 6 two ends are clamped, and locking strip 4 two ends strain at left and right strap 2,2 ' simultaneously, left and right nut by the setting of rotational lock bar 4 two ends, just can clamp iron core 6 middle parts,, many group locking strips can be installed between 2 ' at left and right strap 2, make locking strip 4 make iron core evenly stressed, closely superimposed.
