Description
Technical field
The utility model relates to field transformer, particularly relates to a kind of triangle three-dimensional reel iron core transformer folder.
Background technology
Triangle three-dimensional reel iron core transformer has the features such as three-phase magnetic circuit symmetry, exciting current is little, no-load loss is low, harmonic wave is little, noise is low because of it, is applied widely.Volume iron core is the core of transformer, and to be reeled on the winder formation single frame by trapezoidal material strip, three single frames piece together complete iron core, and iron core is fixed on folder after coiling.The folder of triangle three-dimensional reel iron core transformer is connected and composed by connecting rod by upper clamping piece and lower clamping piece usually, but spacing between existing folder its upper clamping piece and lower clamping piece is fixing often cannot regulate, the triangle three-dimensional winding iron core of various different length specification cannot be adapted to.In addition, current folder is generally formed by steel manufacture, effectively can ensure stability, the integrality of transformer core and clamping structure, but the cost of steel is high, from great, and due to its conductive performance, although done insulation processing, but be easy to produce eddy current in the stray field of alternation, increase supplementary load loss, this has larger impact to the manufacturing cost of transformer and economical operation.
Utility model content
Upper clamping piece and lower clamping piece spacing can be regulated in order to the purpose of this utility model that solves the problem is to provide, lightweight and a kind of triangle three-dimensional reel iron core transformer folder of loss can not be increased.
In order to realize above object, the technical solution adopted in the utility model is: a kind of triangle three-dimensional reel iron core transformer folder, is characterized in that; Comprise upper clamping piece and lower clamping piece that fiberglass reinforcing material is made, the outer wall of described upper clamping piece and lower clamping piece is provided with support plate, described support plate is provided with the connecting hole for connecting screw rod and connects upper clamping piece and lower clamping piece by screw rod, described upper clamping piece also comprises the built-in beam for fixing coiling, and described lower clamping piece also comprises the footing of " Y " shape be made by fiberglass reinforcing material being arranged on bottom.
Further, described lower clamping piece and footing are formed in one structure.
The beneficial effects of the utility model are, be connected thus can regulate the spacing between upper clamping piece and lower clamping piece between upper clamping piece with lower clamping piece by screw rod; Upper clamping piece, lower clamping piece and footing adopt fiberglass reinforcing material to be made, and effectively can alleviate the overall weight of folder and owing to adopting the high supplementary load loss decreasing transformer of the insulation property of this material, significantly improve economic benefit.Footing adopts " Y " shape structure can reinforce the structure of lower clamping piece further.
But lower clamping piece and footing adopt the connection of integrated formed structure lower clamping piece and footing, and more closely its structure is more stable, can also reduce operation aborning, enhance productivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the vertical view of lower clamping piece.
Wherein, 1 is upper clamping piece, and 11 is built-in beam, and 2 is lower clamping piece, and 21 is footing, and 3 is screw rod, and 4 is support plate.
Embodiment
Now with specific embodiment, the utility model technical scheme required for protection is described in further detail by reference to the accompanying drawings.
As depicted in figs. 1 and 2, the folder of this enforcement comprises the upper clamping piece 1 and lower clamping piece 2 that are connected by screw rod 3, wherein on the outer wall of upper clamping piece 1 and lower clamping piece 2, be provided with support plate 4, screw rod 3 passes the connecting hole on support plate 4 and is fixed support plate 4 by the nut on screw rod 3, makes screw rod 3 connect upper clamping piece 1 and lower clamping piece 2 by such mode; When needing to regulate the spacing of upper clamping piece 1 and lower clamping piece 2, the position of adjusting nut is made to regulate relative position between upper clamping piece 1 and lower clamping piece 2 thus by the nut on rotary screw 3.
Upper clamping piece 1 is provided with the built-in beam 11 for fixed triangle three-dimensional winding iron core, bottom lower clamping piece 2, is then provided with the footing 21 support triangle three-dimensional winding iron core of " Y " shape, adopt " Y " shape structure can also reinforce the structure of lower clamping piece 2 further.When being fixed triangle three-dimensional winding iron core, the spacing of adjustable upper clamping piece 1 and lower clamping piece 2, more jointly coordinated by built-in beam 11 and footing 21 and clamp triangle three-dimensional winding iron core and make it more stably be fixed on folder.
Upper clamping piece 1, lower clamping piece 2 and footing 21 adopt fiber glass reinforcement manufacture to form, and wherein lower clamping piece 2 and footing 21 adopt integrated formed structure, also can reduce production process and enhance productivity the while of making both combinations more firm.Compared with steel, the mechanical strength of fiber glass reinforcement close to and also density is less, insulating properties thermal endurance and corrosion resistance also better.Because the insulating properties of fiber glass reinforcement is better, therefore can not produce vortex flow in stray field, increase supplementary load loss.
The examples of implementation of the above are only the preferred embodiment of the utility model, not limit practical range of the present utility model with this, therefore the change that all shapes according to the utility model, principle are done, all should be encompassed in protection range of the present utility model.
