Abstract
The invention discloses amorphous transformer iron cores, including the O-shaped ontology with window, four angles of the ontology have radian, the window has a pair of parallel horizontal edge and a pair of parallel longitudinal edge, adjacent horizontal edge, longitudinal edge junction are formed with cambered R angles, and the longitudinal edge is equipped with several No.1 reinforcing ribs.The present invention in window widthwise edge, longitudinal edge by setting reinforcing rib on the one hand can improve the intensity of iron core in itself, extend its service life, on the other hand can make coil it is orderly be wrapped in iron core surface, form equidistant canoe, improve the service efficiency of iron core.In addition, the insulation resin in the coating of iron core surface can be well to iron core and the deformation that is heat-insulated and preventing coil of insulating oil progress first time.
Description
Technical field
The invention belongs to non-crystalline material fields, and in particular to a kind of amorphous transformer iron core.
Background technology
In recent years, in power distribution transformer, the various transformers using amorphous thin ribbon as its core material are developed
Iron core, and it is practical.The amorphous thin ribbon that this kind of transformer core uses is to carry out super chilling to the molten mass of magnetic alloy
And manufacture, iron loss is very small, has excellent magnetic characteristic.
In the past, in the wound core of non-crystalline material, in order to remove because the stress by being generated during lamination formation iron core, with
The state of wound core is annealed in magnetic field, after annealing, the overlap joint combination side of wound core is opened and is inserted into coil, inserted
Enter after coil that overlap joint is bonded transformer again.Transformer is for mechanicalness protection and heat dissipation and full of the closed of insulating oil
It is used in case.
Traditional amorphous transformer iron core is simple geometry shape, and such as O-shaped, c-type etc., this kind of iron core is deposited when in use
In a common fault, used after being wound due to iron core needs by coil, above-mentioned geometric form iron core is after wound around coil, coil
It easily loosens or slides, cause local coil overstocked and another coil sections extra loose, affect its transformation power.In addition, iron
Heart wound around coil position can generate certain thermal energy, directly contact the generation that can cause bubble for a long time with insulating oil.
Invention content
Goal of the invention：In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of amorphous transformer iron core.
Invention content：In order to reach foregoing invention purpose, what the present invention was specifically performed by：Amorphous transformer iron
The heart, including the O-shaped ontology with window, four angles of the ontology have radian, and the window has a pair of parallel horizontal edge
With a pair of parallel longitudinal edge, adjacent horizontal edge, longitudinal edge junction are formed with cambered R angles, and the longitudinal edge is equipped with several one
Number reinforcing rib.
Wherein, spacing is identical between the adjacent No.1 reinforcing rib.
Wherein, the horizontal edge is equipped with several No. two reinforcing ribs.
Wherein, spacing is identical between No. two adjacent reinforcing ribs.
Wherein, isolation iron core and insulating oil are on the one hand played coated with resin layer in the side that the ontology is parallel to window
Between thermal energy effect, on the other hand can prevent coil from deforming in use.
Wherein, the coating height of the resin layer is more than the 2/3 of ontology profile height.
Advantageous effect：The present invention is compared with traditional technology, by setting reinforcing rib on the one hand in window widthwise edge, longitudinal edge
The intensity of iron core in itself can be improved, extend its service life, on the other hand can make coil it is orderly be wrapped in iron core surface,
Equidistant canoe is formed, improves the service efficiency of iron core.In addition, the insulation resin in the coating of iron core surface can be fine
Ground carries out iron core and insulating oil the deformation that is heat-insulated and preventing coil of first time.
