Description
Technical field
The invention belongs to transformer technology field；Particularly relate to a kind of high voltage transformer insulation nail pressing bowl structure.
Background technology
At present, large-scale high voltage transformer is all that Transformer Winding is compressed using insulation nail pressing bowl structure, but is only that simple bag pressure is combined between embedded component and outsourcing insulating paper flaggy herein in insulation nail pressing bowl structure；Because outsourcing insulating board protected from environmental, used can integrally generate contraction, the shrinkage factor of the outsourcing insulating board is：Longitudinal direction 0.34%, horizontal 0.79%, thickness are to 5.9%, therefore finished parts place certain hour, and embedded component will be produced to depart from shaking phenomenon with outsourcing insulating paper flaggy；There is very big potential safety hazard to the normal operation of transformer.
The content of the invention
The present invention makes up the deficiencies in the prior art aiming above mentioned problem, there is provided a kind of high voltage transformer insulation nail pressing bowl structure；The stability rocked problem, improve nail pressing bowl for thoroughly solving nail pressing bowl of the invention；Not only there are the present invention good insulating properties to prevent partial discharge from producing, and again being capable of effectively coil pressing, it is ensured that the normal safe operation of transformer.
To achieve the above object, the present invention is adopted the following technical scheme that.
High voltage transformer of the present invention is insulated nail pressing bowl structure, including coil, iron core, folder, and skeleton is constituted with unshakable in one's determination by the folder in transformer body, and coil is socketed on iron core；Its structural feature is：Connecting plate is welded with the folder, nut is welded with the connecting plate, nail pressing is rotary with the nut；The coil upper end is stamped pressing plate, and nail pressing bowl, the nail pressing spinning to nail pressing bowl bottom are provided with the pressing plate；The nail pressing bowl includes nail pressing bowl embedded component, adhesive layer, nail pressing bowl outsourcing ply of board from inside to outside, the nail pressing bowl outsourcing ply of board inclusion is fixedly connected outside nail pressing bowl embedded component by the adhesive layer being arranged between nail pressing bowl embedded component and nail pressing bowl outsourcing ply of board.
Used as a preferred embodiment of the present invention, the nail pressing bowl embedded component is metal embedded component.
Used as another preferred scheme of the invention, the adhesive layer uses adhesive, uniform to brush in 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 present invention, nail pressing bowl is that the nail pressing bowl embedded component that sets from inside to outside, adhesive layer, nail pressing bowl outsourcing ply of board constitute the structure combined closely, by this kind of nail pressing bowl structure, thoroughly solve the stability rocked problem, improve nail pressing bowl of nail pressing bowl；Not only there are the present invention good insulating properties to prevent partial discharge from producing, and again being capable of effectively coil pressing；Ensure that the normal safe operation of transformer.
Brief description of the drawings
In order that technical problem solved by the invention, technical scheme and beneficial effect become more apparent, below in conjunction with the drawings and the specific embodiments, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only used to explain the present invention, it is not intended to limit the present invention.
Fig. 1 is the structural representation of high voltage transformer insulation nail pressing bowl structure of the present invention.
In figure：1 it is coil, 2 be pressing plate, 3 be nail pressing cushion block, 4 be nail pressing bowl, 5 be nail pressing bowl outsourcing ply of board, 6 be nail pressing, 7 be adhesive layer, 8 be nut, 9 be nail pressing bowl embedded component, 10 be connecting plate, 11 is folder.
Specific embodiment
With reference to shown in accompanying drawing 1, high voltage transformer insulation nail pressing bowl structure of the present invention, including coil 1, iron core, folder 11, skeleton is constituted with unshakable in one's determination by the folder 11 in transformer body, socket coil 1 on iron core；Its structural feature is：Connecting plate 10 is welded with the folder 11, is welded with the connecting plate 10 in nut 8, the nut 8 and is rotary with nail pressing 6；Pressing plate 2 is stamped in the upper end of the coil 1, and nail pressing bowl 4, the spinning of the nail pressing 6 to 4 bottoms of nail pressing bowl are provided with the pressing plate 2；The nail pressing bowl 4 includes nail pressing bowl embedded component 9, adhesive layer 7, nail pressing bowl outsourcing ply of board 5 from inside to outside, the nail pressing bowl outsourcing ply of board 5 is included outside nail pressing bowl embedded component 9, and is fixedly connected by the adhesive layer 7 being arranged between nail pressing bowl embedded component 9 and nail pressing bowl outsourcing ply of board 5.
The nail pressing bowl embedded component 9 is metal embedded component.
The adhesive layer 7 uses adhesive, uniform to brush in the outer surface of nail pressing bowl embedded component 9；The adhesive has excellent oil resistant insulating performance and bond properties, can make nail pressing bowl embedded component 9 and the strong bonded of nail pressing bowl outsourcing ply of board 5, and thoroughly solve nail pressing bowl 4 rocks problem.
It is appreciated that, above with respect to specific descriptions of the invention, it is merely to illustrate the present invention and is not limited to the technical scheme described by the embodiment of the present invention, it will be understood by those within the art that, still the present invention can be modified or equivalent, to reach identical technique effect；As long as satisfaction uses needs, all within protection scope of the present invention.
