Abstract
The utility model relates to a compressing structure of a transformer body, which comprises an auxiliary pressure plate structure which is arranged on a pressure plate, wherein the auxiliary pressure plate structure is provided with a pressure screw structure. The compressing structure is applied to the fixing of the transformer body and integrates the advantages of the pressure screw structure and the auxiliary pressure plate structure, so that the degree of tightness can be adjusted, and the contact area between the compressing structure and the pressure plate is large, and the compressing force is large, and the tightening effect is good. By adopting the structure, the length of the pressure screw bolt is greatly reduced, and the volume of the transformer is reduced, and the cost is reduced; the leading wire is led out nearby an insulation cushion block, so that the insulation distance is easy to be controlled.
Description
Technical field
The utility model relates to a kind of compressing structure, specifically is the compressing structure that is applied in transformer body.
Background technology
At present, two kinds of structures are generally all adopted in compressing of transformer body, press pin structure and auxiliary pressure plate structure that is:.
All there is certain shortcoming in these two kinds of structures.Adopt and press pin structure, degree of tightness scalable when fastening, but owing to press nail and pressing plate contact area smaller, so thrust is less, fixed effect is poor; Press nail to be conductor, form the wedge angle electrode in electric field, electric field is inhomogeneous on every side, and the insulation distance between the lead-in wire is wayward, and for the product of high pressure, insulation distance is very big, has increased volume of transformer and cost greatly especially.Auxiliary pressure plate structure be with cross-over block with jam-pack between fixture and the pressing plate, its advantage is bigger with the pressing plate contact area, so thrust is bigger; Auxiliary pressing plate is an insulating material, and the end field intensity is evenly distributed, and insulation distance is controlled easily.The shortcoming of auxiliary pressure plate structure is that degree of tightness can not be regulated, and particularly causes loosening after the long-distance transport easily.
Summary of the invention
At above-mentioned problem, the utility model provides a kind of novel structure, easy to use, scalable degree of tightness, has compressed the compressing structure of effective transformer body.
The compressing structure that the utility model provides is applied to the fixing of transformer body, combines the advantage of pressing pin structure and auxiliary pressure plate structure, is included in pressing plate and is provided with auxiliary pressure plate structure, is provided with the pressure pin structure on the auxiliary pressure plate structure.This structure has overcome the shortcoming of two kinds of structures, effectively stationary transformer device body.
Above-mentioned auxiliary pressure plate structure is an at least one group of cross-over block, and cross-over block and pressing plate contact area are big, and the end field intensity is good, and thrust is bigger.
The pressure oncomelania bolt that above-mentioned pressure pin structure comprises hold-down nut and is equipped with it, the hold-down nut below also is provided with and the stop nut of pressing the oncomelania bolt to cooperate, and is provided with insulation cushion under the pressure oncomelania bolt.Hold-down nut is fixed on one's body the transformer, like this, presses the oncomelania bolt at first can fixedly connected with hold-down nut, and the cross-over block of below is exerted pressure.Then, stop nut oppositely will press the oncomelania bolt to fix, and make it more firm.Also be provided with insulation cushion under pressing the oncomelania bolt, bear the pressure of bolt, the cross-over block of below is compressed.
The compressing structure that the utility model provides is applied to the fixing of transformer body, combines the characteristics of pressing pin structure and auxiliary pressure plate structure, can regulate degree of tightness, and bigger with the pressing plate contact area, and thrust is also bigger, and is fastening effective.After adopting this structure, press the length of oncomelania bolt to reduce greatly, reduced the volume of transformer, reduced cost; Lead-in wire is by drawing near the cross-over block, and insulation distance is controlled easily.
Description of drawings
Fig. 1 is the structure principle chart of the utility model embodiment.
Wherein, 1. pressing plate, 2. cross-over block, 3. insulation cushion, 4. stop nut, 5. hold-down nut is 6. pressed oncomelania bolt, 7. bolt.
Embodiment
Embodiment with indefiniteness further explains, illustrates the technical program below.
A kind of compressing structure of transformer body is applied to the fixing of transformer body, is included in pressing plate 1 and is provided with one group of cross-over block 2, on the cross-over block 2 bolt 7 can be set, and can horizontal direction be located by cross-over block.The cross-over block top is provided with the pressure pin structure, comprise the hold-down nut 5 that is fixed together with transformer body, press oncomelania bolt 6 and hold-down nut 5 to be equipped with, the below of hold-down nut 5 is provided with and the stop nut 4 of pressing oncomelania bolt 6 to cooperate, under pressing oncomelania bolt 6 insulation cushion 3 is arranged, insulation cushion 3 bears the pressure of bolt, pressure is passed to the cross-over block 2. of below again
During use, press oncomelania bolt 6 and hold-down nut 5 to fix, can exert pressure by 3 pairs of cross-over blocks 2 of insulation cushion, cross-over block 2 imposes on pressure pressing plate 1 again, and stop nut 4 is oppositely fixing, has so just realized fixing transformer body.Simultaneously, press oncomelania bolt 6 and stop nut 4 can in needs, regulate fixing degree of tightness.
