Description
Technical field
The utility model is related to a kind of oil-filled transformer machine body structure of resistance to shorting.
Background technology
Transformer body is made up of iron core, high-tension coil, low-voltage coil, folder, insulation, lead etc., high-voltage coil and low-voltage coil point
Be not enclosed within three core limbs, including low pressure, high pressure outside, during transformer station high-voltage side bus, sudden instantaneous short circuit, load close a floodgate etc. moment
Load variations can all cause transformer immediate current excessive, and then rush of current is caused to transformer, impact of the coil in electric current
Under effect, it is axial and it is radial can all produce a very big mechanical force, be axially the power spread to coil two ends from thiol,
Radial is that interior loop produces the power to contract, and exterior loop produces the power for expanding outwardly.
At present, it can be common that in coil axial direction, upper and lower side is respectively provided with cross-over block, is compressed by folder, makes axial masterpiece
For cushion block, make coil axially indeformable, coil is radial, survey in interior loop and be close to iron core, convergent force directly acts on iron core
On, do not cause interior loop contraction distortion, and the unrestricted thing in exterior loop outside, when the radial outside expansionary force of coil is more than coil sheet
During the limit that body intensity can bear, coil will produce radial deformation, and especially the straight line portion of Long Circle coil is the brightest
It is aobvious, damage in insulation is caused, and then burn out transformer.
The content of the invention
For the problem that above-mentioned prior art is present, the utility model provides a kind of oil-filled transformer device body of resistance to shorting
Structure, the deformation that the structure can not only be between limiting coil, moreover it is possible to which limiting coil two ends deform.
To achieve these goals, the utility model provides a kind of oil-filled transformer machine body structure of resistance to shorting, including
Unshakable in one's determination, coil and folder, described coil is enclosed within iron core, and coil axial direction upper and lower side is respectively provided with cross-over block, by folder
Compress, coil includes high-tension coil and low-voltage coil, and including low-voltage coil, high-tension coil outside, is provided between adjacent windings
Phase partition, in the outer end of the coil at two ends external partition is provided with, and side plate is fixedly connected with the outside of external partition.
In the technical scheme, by filling phase partition between adjacent windings, such coil is mutually supported with coil,
Radial expansionary force is acted on dividing plate, limit the deformation between coil；By the outer end of the coil at two ends be provided with it is outer every
Plate, then side plate is provided with the outside of external partition, make coil two ends external partition inner side be close to coil, outside is snugly fitted on folder
Side plate on, limit coil two ends and be deformed, efficiently avoid damage in insulation so that burn out transformer phenomenon occur.
Further, phase partition includes insulating press boards and insulating stay, and insulating stay is symmetrically fixed on insulating press boards
Both sides.
Further, external partition includes insulating press boards and insulating stay, and insulating stay is separately fixed at the insulation pressure at two ends
Plate is each near the side of coil.
Further, in order to increase the steadiness of side plate, the upper and lower ends of side plate are fixed on folder.
