Abstract
The present invention relates to a plane fracture-type wound iron core used for a three-phase plane fracture-type wound iron core transformer. The plane fracture-type wound iron core comprises two identical small-frame iron cores and a large-frame iron core. Each single frame iron core is formed by sequential socket joint of several iron core sheets, each iron sheet of each single frame iron core only has a fracture seam on a core stem, and two adjacent seams are staggered. According to the invention, the transformer made of the plane fracture-type wound iron core has the advantages of superior electromagnetic performance, small excitation current, low no-load loss, low noise, light weight, material and energy conservation, convenient processing, and so on.
Description
Technical field
The present invention relates to a kind of plane fracture type rewinding material, for three-phase and single-phase fracture type Wound iron-core transformer, both can be used for various oil-filled transformer, and also can be used for various dry-type transformer.
Background technology
The iron core of traditional three-phase Wound iron-core transformer is that a kind of closed single frame by the coiling of continuous print silicon strip is unshakable in one's determination, and be bolted together composition three-phase transformer core.The greatest problem of three-phase closed winding iron-core transformer is that coil must coiling on finished iron stem, make the anufacturability of product poor, production efficiency is low, quality is not easy to control, product repairing difficulty, can only manufacture the transformer compared with low capacity, manufacturing enterprise needs to drop into the reasons such as a large amount of special equipments, and the popularization of this technology is very restricted.
The stack mode of existing electrical sheet life has two kinds, and one is laminated core, and one is that roll film is unshakable in one's determination.Laminated core has superior processing performance, and roll film iron core has superior electromagnetic performance.
Summary of the invention
An object of the present invention overcomes the deficiencies in the prior art, provides a kind of performance close with rewinding material, is not only conducive to guiding when unshakable in one's determination and coil combination, and conveniently can realize the combination of lamination and the plane fracture type rewinding material of docking closed assembly.
According to technical scheme provided by the invention, described plane fracture type rewinding material, it comprises the unshakable in one's determination and large frame iron core of two identical little frames.The unshakable in one's determination socket by some lamination orders of each single frame is formed, and every one deck lamination of each single frame iron core only has fracture seam on stem, and adjacent two layers seam is in shifting to install.
The cross section of each single frame iron core is square and oval and circular.
The fracture seam of each single frame all laminations unshakable in one's determination is in shifting to install.
The transformer using plane fracture type rewinding material of the present invention to make has superior electromagnetic performance, the features such as exciting current is little, and no-load loss is low, and noise is low, and volume is little, lightweight, saving metal material and energy, easy to process.Plane fracture type Wound iron-core transformer has superior processing performance, and enable the large portion of the present invention realize the mechanization manufactured unshakable in one's determination, the split manufacture of iron core and coil, all effectively must be solved coil by all problems of coiling on core limb.The stress produced in unshakable in one's determination and coil groups process of assembling is less, can reduce the supplementary load loss of iron core greatly.Manufacturing enterprise does not need to drop into a large amount of plant equipment and a large amount of processing staff, and the lamination of each single frame iron core only needs to be formed with special plant equipment bending.
The present invention both can be used for various oil-filled transformer, also can be used for various dry-type transformer.
