Description
Technical field
The utility model relates to a kind of device for transformer, the oval low voltage foil winding coil winding of especially a kind of transformer shaped device.
Background technology
Along with the development need of transformer industry, the most transformer production 10kV of producer distribution transformer all adopts oval structure, and the improvement of oval structure still adopts the winding of wire-wound technique coiling to cause the critical technological points such as coiling difficulty is large, moulding is difficult to low-voltage coil.Therefore low-voltage coil adopts the technique for coiling of copper (aluminium) paper tinsel to become a kind of main flow trend in industry.Paper tinsel around advantage be: 1. volume compact, thereby the activity coefficient of transformer barred window is high, volume of transformer is reduced, weight saving; 2. mechanical strength is high, and not yielding, anti-short circuit capability is strong; 3. electrical strength is good, impacts gradient voltage and is evenly distributed; 4. be conducive to mechanization production, enhance productivity.Institute thinks supporting oval low voltage foil winding coil winding, must design a set of coil winding shaped device that is applicable to this class formation.
Utility model content
The purpose of this utility model is to provide a kind of dress, tears the oval low voltage foil winding coil winding of transformer shaped device easily open.
The oval low voltage foil winding coil winding of the transformer shaped device of realizing the utility model object, comprises two half module cylinders, a cylindricality mould cylinder of described two half module cylinders composition, and the sectional area shape of described mould cylinder is similar to ellipse; Described half module cylinder comprises semicylinder, and the top of described semicircle main body is provided with fagging, and bottom is provided with lower fagging, and middle part is provided with interior fagging; Top and the bottom of two described half module cylinders are respectively equipped with end plate, and described end plate is fixed on two half module cylinders by construction bolt, and two half module cylinders are fixed together; The semicircle body hook middle part of one of them half module cylinder is provided with a platform, and described platform one side is welded with positive stop strip.
Described positive stop strip is equally distributed three.
The inner side plane of described half module cylinder is provided with rectangular recess, a square shaft hole of rectangular recess composition of two half module cylinders, and the center of described end plate is also provided with square shaft hole.
The beneficial effects of the utility model are as follows: 1) the oval low voltage foil winding coil winding of transformer of the present utility model shaped device is simple in structure, easy to use, easy accessibility in device use procedure; Can greatly reduce dress in device use procedure, tear labour intensity open, increase work efficiency; 2) positive stop strip on mould cylinder to paper tinsel coiling enclose around outlet inner copper line play position-limiting action, ensure to come in outlet and in coil winding process, do not produce skew; 3) end plate versatility is good, can be used as the general end plate of each capacity and uses.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is work schematic diagram of the present utility model.
Embodiment
Embodiment of the present utility model is as follows: as shown in Figure 1, 2, the oval low voltage foil winding coil winding of transformer of the present utility model shaped device, comprise two half module cylinders 2, described two half module cylinders 2 form a cylindricality mould cylinder, and the sectional area shape of described mould cylinder is similar to ellipse; Described half module cylinder 2 comprises semicylinder, and the top of described semicircle main body is provided with fagging 5, and bottom is provided with lower fagging 7, and middle part is provided with interior fagging 6; The top of two described half module cylinders 2 and bottom are respectively equipped with end plate 3, and described end plate 3 is fixed on two half module cylinders 2 by construction bolt 4, and two half module cylinders 2 are fixed together; The semicircle body hook middle part of one of them half module cylinder 2 is provided with a platform 10, and described platform 10 1 sides are welded with positive stop strip 1.
Described positive stop strip 1 is equally distributed three.
The rectangular recess 11 that the inner side plane of described half module cylinder 2 is provided with 11, two half module cylinders 2 of rectangular recess forms a square shaft hole, and the center of described end plate 3 is also provided with square shaft hole.
Operation principle of the present utility model is as follows: as shown in Figure 3, mould cylinder is installed on foil winding equipment by square shaft hole, foil 8 and outlet row 9 firm welding.Rise around time outlet row 9 lie against on the platform 10 of half module cylinder, along with the rotation of paper tinsel winding apparatus, foil 8 and interlayer dielectic are successively wound on mould cylinder, coiling becomes low voltage layer type coil.
Because being subject to the impact of coiling tension force, outlet row 9 can be offset to coiling direction because the rotation of mould cylinder causes the position of starting.The positive stop strip 1 welding on half module cylinder rises around outlet row 9 and has played position-limiting action coil, has guaranteed that outlet row can not produce displacement because of the impact of coiling tension force.
Interior fagging is welded in half module cylinder middle part, plays the effect of strengthening support.Upper and lower fagging is welded in the two ends of half module cylinder, when half module cylinder is strengthened supporting, also plays the effect of being located by connecting to end plate.End plate center is provided with square shaft hole, and periphery is provided with pilot hole, and pilot hole with Central Symmetry, is arranged along triangular apex, ensured the steadiness after die assembly.End plate versatility is good, can be used as the general end plate of each capacity and uses.
Embodiment recited above is described preferred implementation of the present utility model; not scope of the present utility model is limited; design under spiritual prerequisite not departing from the utility model; various distortion and improvement that the common engineers and technicians in this area make technical solutions of the utility model, all should fall in the definite protection range of claims of the present utility model.
