Technical field
The present invention relates to transformer core field, a kind of folding stereo delta transformer open coil iron core of section hexagon is specifically provided.
Background technology
At present, domestic existing stereo triangle transformer open coil iron core mainly includes following two core structures：1st, by three groups of curve silicon steel sheet billots of independence after bending, shearing stack into three open coil iron cores, and three volume iron cores of remaining silent are assembled into sectional area as R type tridimensional triangle iron core structures with 120 ° of inclined-planes, core section product after assembly is rounder and more smooth circular configuration, common name R type volume iron cores；2nd, by three groups of independence by multistage broken line type silicon steel sheet billot after bending, shearing stack into three open coil iron cores, and the director circle type tridimensional triangle iron core structure that three open coil iron cores are assembled into 120 °, common name polygon or be broken line type volume iron core.The triangular solid reel iron core transformer of both the above structure is assembled by three independent open cores, therefore, tridimensional triangle iron core has magnetic circuit most short and each phase is certainly into the full symmetric equal characteristic in loop, but, both the above form is respectively present problems with, sectional area is approximately circular for R sections stems cross section, fill factor is higher, but stock utilization is low, only 87%-92% or so, although and polygon or broken line type volume iron core stock utilization are high, but need to store tens kinds of silicon steel sheet billots of width in actual production process, so as to increase production cost, production efficiency is relatively low.
Therefore, the improvement in structure how is carried out to existing delta transformer open coil iron core, to improve the utilization rate of silicon steel sheet material strip, production cost be reduced, as people's problem demanding prompt solution.
The content of the invention
In consideration of it, it is an object of the invention to provide a kind of folding stereo delta transformer open coil iron core of section hexagon, at least to solve when opening coiled core of transformer is manufactured, the problems such as the utilization rate of silicon steel sheet material strip is low, production cost is high.
The present invention provide technical scheme be：A kind of folding stereo delta transformer open coil iron core of section hexagon,Including iron core group,Iron core group be by the single-phase open core of three independences and size structure all same with the angle seamless assembled of central angle 120 into 3-D triangle structure,The middle vacancy of single-phase open core is window,The upper end of the window of single-phase open core is upper yoke,The lower end of the window of single-phase open core is lower yoke,It is stem between upper yoke and lower yoke,Stack is made up of into every group of silicon steel sheet material strip of single-phase open core the first material strip of rectangle and second material strip two parts of right angled triangle,Second material strip is gradually reduced along the bearing of trend width of the first material strip,By every group of silicon steel sheet material strip through bending,After shearing stack into single-phase open core stem section be in isosceles trapezoid,Three sections of post of the iron core group after assembly are in regular hexagon.
It is preferred that, every single-phase open core is provided with two groups of fractures, and two groups of fractures are respectively arranged at two tops of stem of single-phase open core.
Further preferably, the single-phase open core is to roll up iron core with eight square shapes at 135o or 12 150o bendings angle.
Beneficial effects of the present invention are：
1st, three sections of post of the iron core group after present invention assembly are in regular hexagon, and approximate circle, fill factor is high；
2nd, the three-phase three-column stereoscopic stable of the folding stereo delta transformer open coil iron core of section hexagon of the present invention, fully ensure that three-phase magnetic circuit is balanced, therefore third-harmonic component forms closed-loop path in independent inframe, largely reduces the harmonic component of no-load current；
3rd, during making the folding stereo delta transformer open coil iron core of section hexagon of the present invention, the utilization rate of silicon steel sheet material strip raw material is 100%, and the iron core of every kind of capacity only needs to a kind of width silicon steel sheet material strip raw material, not only increase the utilization rate of silicon steel sheet material strip raw material, the stock of raw material is decreased, production cost is reduced.
