Description
Technical field
The utility model belongs to transformer technology field; Relate to a kind of high voltage transformer insulation nail pressing bowl structure specifically.
Background technology
At present, large-scale high voltage transformer is all adopt insulation nail pressing bowl structure to compress Transformer Winding, but in this insulation nail pressing bowl structure, is only that simple bag pressure is combined between embedded component with outsourcing insulating paper flaggy; Due to the impact by environment, outsourcing insulating board entirety used can generate contraction, the shrinkage of described outsourcing insulating board is: longitudinally 0.34%, laterally 0.79%, thick in 5.9%, therefore finished parts places certain hour, will produce embedded component and outsourcing insulating board pull-up from shaking phenomenon; Very large potential safety hazard is had to the normal operation of transformer.
Summary of the invention
The utility model is exactly for the problems referred to above, makes up the deficiencies in the prior art, provides a kind of high voltage transformer insulation nail pressing bowl structure; What the utility model thoroughly solved nail pressing bowl rocks problem, improves the stability of nail pressing bowl; The utility model not only has the good insulation property office of preventing and puts generation, and again can coil pressing effectively, ensure that the normal safe of transformer runs.
For achieving the above object, the utility model adopts following technical scheme.
The utility model high voltage transformer insulation nail pressing bowl structure, comprises coil, iron core, folder, forms skeleton, iron core is socketed coil in transformer body by described folder with unshakable in one's determination; Its structural feature is: described folder is welded with connecting plate, and described connecting plate is welded with nut, is rotary with nail pressing in described nut; Described coil upper end is stamped pressing plate, described pressing plate is provided with nail pressing bowl, and described nail pressing spinning is to nail pressing bowl bottom; Described nail pressing bowl comprises nail pressing bowl embedded component, adhesive layer, nail pressing bowl paper wrapper flaggy from inside to outside, described nail pressing bowl paper wrapper flaggy inclusion outside nail pressing bowl embedded component, and is fixedly connected with by the adhesive layer be arranged between nail pressing bowl embedded component with nail pressing bowl paper wrapper flaggy.
As a kind of preferred version of the present utility model, described nail pressing bowl embedded component is metal embedded component.
As another kind of preferred version of the present utility model, described adhesive layer adopts adhesive, and evenly brushing is at the outer surface of nail pressing bowl embedded component.
Beneficial effect of the present invention.
High voltage transformer insulation nail pressing bowl structure provided by the utility model, described nail pressing bowl be arrange from inside to outside nail pressing bowl embedded component, adhesive layer, nail pressing bowl paper wrapper flaggy form the structure of combining closely, by this kind of nail pressing bowl structure, what thoroughly solve nail pressing bowl rocks problem, improves the stability of nail pressing bowl; The utility model not only has the good insulation property office of preventing and puts generation, and again can coil pressing effectively; Ensure that the normal safe of transformer runs.
Accompanying drawing explanation
The technical problem solved to make the utility model, technical scheme and beneficial effect are clearly understood, below in conjunction with the drawings and the specific embodiments, are further elaborated to the utility model.Should be appreciated that embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Fig. 1 is the structural representation of the utility model high voltage transformer insulation nail pressing bowl structure.
In figure: 1 be coil, 2 be pressing plate, 3 be nail pressing cushion block, 4 be nail pressing bowl, 5 be nail pressing bowl paper wrapper flaggy, 6 be nail pressing, 7 be adhesive layer, 8 be nut, 9 be nail pressing bowl embedded component, 10 be connecting plate, 11 for folder.
Embodiment
By reference to the accompanying drawings shown in 1, the utility model high voltage transformer insulation nail pressing bowl structure, comprises coil 1, iron core, folder 11, forms skeleton, iron core is socketed coil 1 in transformer body by described folder 11 with unshakable in one's determination; Its structural feature is: described folder 11 is welded with connecting plate 10, and described connecting plate 10 is welded with nut 8, is rotary with nail pressing 6 in described nut 8; Pressing plate 2 is stamped in described coil 1 upper end, and described pressing plate 2 is provided with nail pressing bowl 4, bottom described nail pressing 6 spinning to nail pressing bowl 4; Described nail pressing bowl 4 comprises nail pressing bowl embedded component 9, adhesive layer 7, nail pressing bowl paper wrapper flaggy 5 from inside to outside, described nail pressing bowl paper wrapper flaggy 5 inclusion outside nail pressing bowl embedded component 9, and is fixedly connected with by the adhesive layer 7 be arranged between nail pressing bowl embedded component 9 with nail pressing bowl paper wrapper flaggy 5.
Described nail pressing bowl embedded component 9 is metal embedded component.
Described adhesive layer 7 adopts adhesive, and evenly brushing is at the outer surface of nail pressing bowl embedded component 9; Described adhesive has excellent oil resistant insulating performance and bond properties, can make nail pressing bowl embedded component 9 and nail pressing bowl paper wrapper flaggy 5 strong bonded, and what thoroughly solve nail pressing bowl 4 rocks problem.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection range of the present utility model as long as meet.
