Abstract
The utility model provides an elastic compressing device for a coil of a dry-type transformer. The elastic compressing device comprises a bolt, a threaded sleeve, a clamping piece, a locking nut, a pressing piece, a disc-type spring and a cushion block, wherein the threaded sleeve is welded on the clamping piece, the bolt is screwed into the threaded sleeve, the bottom of the threaded sleeve on the bolt is provided with the locking nut, the lower end of the bolt pushes against the pressing piece, the pressing piece presses the disc-type spring, and both the disc-type spring and the pressing piece are pressed into a groove of the cushion block. The double looseness prevention of the bolt can be realized through the locking nut and the disc-type spring, so that the problem that the coil is likely to loosen when the dry-type transformer is hoisted in a factory and during the transportation process of the dry-type transformer can be solved.
Description
Technical field
The utility model relates to a kind of device compressed for dry-type transformer coil, belongs to dry-type transformer coil compaction techniques field.
Background technology
At present, popular dry-type transformer coil compressing structure is generally as shown in Figure 1 on the market, and coil 7 compresses by bolt 2, and bolt 2 is screwed on the silk braid 3 on folder 1, and folder 1 is the parts on dry-type transformer.The end of bolt 2 is pressed on casting die 5, and casting die 5 is arranged in the groove of cushion block 6, and casting die 5 compresses cushion block 6 and coil 7, for locking, on bolt 2 and the bottom that is positioned at silk braid 3 also have locking nut 4.But, after long-distance transportation or permanent the use, due to a variety of causes, bolt 2 and locking nut 4 can be loosening, lose the compression to coil 7, affect the service behaviour of dry-type transformer.
Summary of the invention
The deficiency that the utility model exists for existing dry-type transformer coil compaction techniques, provide a kind of and can effectively prevent the elastic pressuring clamping device that dry-type transformer coil is loosening.
Dry-type transformer coil elastic pressuring clamping device of the present utility model, by the following technical solutions:
This dry-type transformer coil elastic pressuring clamping device, comprise bolt, silk braid, folder, locking nut, casting die, disk spring and cushion block, silk braid is welded on folder, bolt is screwed in silk braid, be provided with locking nut in the silk braid bottom on bolt, the top, lower end of bolt is pressed on casting die, and casting die is pressed on disk spring, and disk spring and casting die are all in the groove of cushion block.By casting die, cushion block and coil are compressed.
The utility model is realized the dual locking of bolt by locking nut and disk spring, has solved dry-type transformer in the easy loosening problem of the lifting of dispatching from the factory, transportation coil.
The accompanying drawing explanation
Fig. 1 is the schematic diagram of existing dry-type transformer coil compressing structure.
Fig. 2 is the structural representation of the utility model dry-type transformer coil elastic pressuring clamping device.
Wherein: 1, folder, 2, bolt, 3, silk braid, 4, locking nut, 5, casting die, 6, cushion block, 7, coil, 8, T shape casting die, 9, disk spring.
Embodiment
As shown in Figure 2, dry-type transformer coil elastic pressuring clamping device of the present utility model comprises folder 1, bolt 2, silk braid 3, locking nut 4, T shape casting die 8, disk spring 9 and cushion block 6, cushion block 6 is pressed on coil 7, be placed with disk spring 9 and T shape casting die 8 in the groove of cushion block 6, T shape casting die 8 strings are pressed on disk spring 9, bolt 2 is screwed in the silk braid 3 be welded on folder 1, and its top, lower end is pressed on T shape casting die 8, and plays fixing locking effect by locking nut 4.The utility model and existing coil compressing structure difference are to have increased disk spring 9 in the groove of cushion block 6, and casting die has also been done change, for T shape structure, the lower end string is pressed on disk spring 9, by disk spring 9 compressions, the compressed rear generation distortion of disk spring 9, effectively prevent the loosening of bolt 2 and locking nut 4 with the storage power form.
