Abstract
The utility model discloses a transformer body holding device, which comprises a lower supporting plate, an upper supporting plate, an upper clamping piece and a lower clamping piece, wherein, a winding is clamped by the upper clamping piece and the lower clamping piece. The transformer body holding device is characterized in that one end of the upper clamping piece is clamped on an upper press plate, and the other end of the upper clamping piece props against a supporting cushion block; the supporting cushion block is supported by a plurality of stays that are arranged along the circumference of a transformer body; a plurality of concave pits are formed on the supporting cushion block; and pressing nails at the end parts of the upper clamping piece are matched with the concave pits. The transformer body holding device enables the winding to be stressed in a balancing manner, improves the overall stability of the transformer body, and ensures that the transformer body can stand the impact tests under various transportation conditions in an oil tank and cannot move.
Description
Technical field
The utility model relates to a kind of transformer body hold down gag, belongs to technical field of electricity.
Background technology
For electric pressure higher oil-filled transformer such as 220KV oil-filled transformer, transformer body must be able to take the impact test under the various transportation conditions and not be shifted in fuel tank.Therefore, must make the winding stress equalization, improve the resistance to overturning of device body.
The utility model content
The utility model technical problem to be solved provides a kind of transformer body hold down gag, makes the winding stress equalization, improves device body resistance to overturning.
For solving the problems of the technologies described above, the utility model provides a kind of transformer body hold down gag, comprises lower pallet, top hold-down; Upper clamping piece, lower clamping piece with the winding clamping is characterized in that, said upper clamping piece one end is connected in said top hold-down; The other end is butted on the lip block; Said lip block is supported by a plurality of stays along device body circumference, and said lip block is provided with a plurality of pits, and the pressure nail of said upper clamping piece end is equipped with said pit.
Said pressure nail is the insulating board material.
With the said stay that corresponding setting is all arranged on the face of the axis normal at said pressure nail place.
With corresponding on the face of the axis normal at each said pressure nail place a said lip block is set, said lip block is piece independently.
With corresponding on the face of the axis normal at a plurality of said pressures nails place a said lip block is set, said lip block is the arcuation piece.
Between said lip block and the said stay laminated sheet is set.
Said stay, pressure nail are on same axis.Said lip block, stay, pressing plate are the insulating board material.
The beneficial effect that the utility model reached:
The transformer body hold down gag of the utility model makes the winding stress equalization, has improved device body resistance to overturning, has guaranteed that transformer is able to take the impact test under the various transportation conditions and is not shifted in fuel tank.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is an A portion partial enlarged drawing among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.Following examples only are used for more clearly explaining the technical scheme of the utility model, and can not limit the protection range of the utility model with this.
Like Fig. 1, shown in Figure 2; The transformer body hold down gag of the utility model comprises lower pallet 1, top hold-down 2, and with upper clamping piece 3, the lower clamping piece of winding clamping, an end of upper clamping piece 3 is stuck on the top hold-down 2; The other end contacts with lip block 4; A plurality of stays 5 are along device body circumference, and lip block 4 is provided with a plurality of pits 6, and the pressure nail 7 of upper clamping piece 3 ends is equipped with pit 6.
Press nail that the corresponding stay 5 that is provided with is all arranged for 7 times.
7 times correspondences of a plurality of pressure nails are provided with a lip block 4, and lip block 4 is the arcuation piece.
One laminated sheet 8 is set between lip block 4 and the stay 5.
Press nail 7, lip block 4, stay 5, pressing plate 8 to be the insulating board material.
When upper clamping piece 3, lower clamping piece effect with top hold-down 2, when lower pallet 1 compresses; Can not be shifted in the pit 6 that the pressure nail 7 of upper clamping piece end enters on the lip block 4; Stay 5 under the lip block 4 is passed to top hold-down 2 with pressure; The single-point power that acts on upper clamping piece 3, pressure nail 7 is converted into the power that acts on top hold-down 8 planes, thereby makes the winding stress equalization.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and distortion, these improvement and distortion also should be regarded as the protection range of the utility model.
