Abstract
Coil strap spring box press-dying arrangements, relates to the dry field of coil.The utility model solves in dry run, and due to coil insulation material dimensional contraction, coil height diminishes, and coil clamping force can reduce even vanishing and cause coil to loosen, and can affect the problem of coil drying effect.Coil strap spring box press-dying arrangements, it is made up of top board, intermediate press plate and lower platen from top to bottom; The surrounding of top board, intermediate press plate and lower platen wears some screw rods; Screw rod is fixed by nut with top board and lower platen respectively; Surrounding position between top board and intermediate press plate is provided with some spring boxes; The lower surface of intermediate press plate and the upper surface of lower platen are respectively fixed with laminated wooden block; Coil to be dried is placed between two laminated wooden blocks.Coil strap spring box press-dying arrangements of the present utility model, provides lasting pressure when coil is dry to coil, makes coil make to be in impaction state eventually, makes coil drying effect better.
Description
Technical field
The utility model relates to the dry field of coil, particularly relates to coil strap spring box press-dying arrangements.
Background technology
In order to ensure that transformer safety is run reliably, prevent transformer coil to be subject to mechanical force impact when short circuit and cause transformer coil deformed damaged, coil must control coil height difference well in dry run, ensures that coil has stable axial dimension, and coil needs to carry out drying under compression.Conventional method utilizes upper and lower two pressing plates and stretching screw that drying is carried out in coil clamping.But in dry run, due to coil insulation material dimensional contraction, coil height becomes short, and clamping screw loosens, and coil clamping force can reduce even vanishing and cause coil to loosen, and can affect coil drying effect.
Utility model content
For solving the problems of the technologies described above, the utility model provides coil strap spring box press-dying arrangements.
The utility model solves the technical scheme that its technical problem adopts: coil strap spring box press-dying arrangements, and it is made up of top board, intermediate press plate and lower platen from top to bottom; The surrounding of described top board, intermediate press plate and lower platen wears some screw rods; Described screw rod is fixed by nut with top board and lower platen respectively; Surrounding position between described top board and intermediate press plate is provided with some spring boxes; The lower surface of described intermediate press plate and the upper surface of lower platen are respectively fixed with laminated wooden block; Coil to be dried is placed between two laminated wooden blocks.
Described spring box is made up of spring pressure pad, spring bearer plate, spring socket sleeve and spring bottom from top to bottom; The inside of described spring socket sleeve is provided with butterfly spring; The spring pressure pad of described spring box contacts with the lower surface of top board; The spring bottom of described spring box and the upper surface of intermediate press plate are fixed.
Described screw rod and top board by the fixing position of nut, be also provided with cushion cover between nut and top board.
Operation principle: coil to be dried is put into coil strap spring box press-dying arrangements, after treating dry coil compression by top board, intermediate press plate and lower platen, then compressed by top board, locking nut, now, spring box is in impaction state; In the process of drying, coil insulation material dimensional contraction, coil height diminishes a bit, and spring case bullet height a bit, provides a pressure to intermediate press plate, impels intermediate press plate to continue to compress to coil, coil is not loosened, makes drying effect fine.
The beneficial effects of the utility model: coil strap spring box press-dying arrangements of the present utility model, when coil is dry, provide lasting pressure to coil, make coil make to be in impaction state eventually, do not loosen, make the drying effect of coil better.

Detailed description of the invention
In order to deepen, to understanding of the present utility model, to be described in further detail the utility model below in conjunction with drawings and Examples, this embodiment, only for explaining the utility model, not forming protection domain of the present utility model and limiting.
Embodiment
As depicted in figs. 1 and 2, coil strap spring box press-dying arrangements, it is made up of top board 1, intermediate press plate 2 and lower platen 3 from top to bottom; The surrounding of described top board 1, intermediate press plate 2 and lower platen 3 wears some screw rods 4; Described screw rod 4 is fixed by nut with top board 1 and lower platen 3 respectively; Surrounding position between described top board 1 and intermediate press plate 2 is provided with some spring boxes 5; The lower surface of described intermediate press plate 2 and the upper surface of lower platen 3 are respectively fixed with laminated wooden block 6; Coil 7 to be dried is placed between two laminated wooden blocks 6; Described spring box 5 is made up of spring pressure pad 51, spring bearer plate 52, spring socket sleeve 53 and spring bottom 54 from top to bottom; The inside of described spring socket sleeve 53 is provided with butterfly spring 55; The spring pressure pad 51 of described spring box 5 contacts with the lower surface of top board 1; The spring bottom 54 of described spring box 5 is fixed with the upper surface of intermediate press plate 2; Described screw rod 4 and top board 1 by the fixing position of nut, be also provided with cushion cover 8 between nut and top board.
The operation principle of the present embodiment: coil 7 to be dried is put into coil strap spring box press-dying arrangements, treat after dry coil is fixed by intermediate press plate 2 and lower platen 3, then top board 1 is compressed, locking nut, now, spring box 5 is in impaction state; In the process of drying, the insulating materials dimensional contraction of coil 7 to be dried, coil 7 to be dried highly diminishes a bit, spring box 5 bullet height a bit, a pressure is provided to intermediate press plate 2, impel intermediate press plate 2 to treat dry coil 7 to continue to compress, coil 7 to be dried is not loosened, makes drying effect fine.
Above-described embodiment should not limit the utility model by any way, and the technical scheme that the mode that all employings are equal to replacement or equivalency transform obtains all drops in protection domain of the present utility model.
