Abstract

The invention discloses a foldable three-dimensional double-opening iron core. The foldable three-dimensional double-opening iron core comprises a double-opening transformer iron core with an L-shaped interlock structure, wherein the iron core is formed by splicing three single-frame double-opening iron cores at a center angle of 120 degrees, and the cross section of the spliced iron core is in an inscribed polygonal shape of a circle, in a circular shape (R type) and in a regular hexagonal shape; the single-frame iron core consists of a plurality of groups of rectangular opening material straps arranged in a rectangular corner area, and a butt-joint position of an opening of each material strap is arranged on two ends of an upper ferrite yoke, two bevel slopes of a rectangle and the upper ends of two core columns. The stacked iron core column and the ferrite yoke are interlocked, so that the mechanical strength of the iron core is improved. Therefore, the iron core has the characteristics of low loss, small noise, high sudden short circuit resistance and high production efficiency.

Description

The two open core of folding stereo

Technical field

The present invention relates to power transmission and transforming equipment field, specifically provide the two open core of a kind of folding stereo .

Background technology

Iron core is the important component part of transformer.In recent years, along with country is to the popularization of energy-conserving product, remain silent " stereoscopic triangular coiled-core transformer " because of its three iron core magnetic performances completely the same, energy-saving effect is significantly widely used.Meanwhile, triangular form appendiron core transformer of remaining silent is because iron core is for remaining silent, so suit coil complex process in the fabrication process, production efficiency is low, and quality is wayward, and product repairing difficulty waits its development of cause influence.At present, a kind of appearance of removable folding stereo open-delta appendiron core transformer, solve the problems referred to above, but also still there is certain deficiency, as: open seam position can only concentrated setting in the upper end of iron core stem stem, very easily cause loosening, displacement, distortion, the seam be buried in end winding brings very large inconvenience to back dowel core, not only have impact on iron core performance, also reduce integrated transformers quality.Therefore, how technologic improvement is carried out to existing transformer core, improve mechanical strength, become the target that people expect.

Summary of the invention

Given this, to achieve these goals, deficiency and the defect of prior art existence is overcome.The invention provides the two open core of a kind of folding stereo.It can not only improve iron core mechanical strength, has more the feature that loss is low, noise is low, anti-sudden short circuit ability is strong, production cost is low.

In order to solve the problem, technical scheme of the present invention is: provide a kind of folding stereo two open core, it comprises and the single frame iron core with L-type interlocking structure identical by three shapes and is put together, each single frame iron core is provided with the two opening material strip group of many groups, and the material strip open butt joint position of two opening material strip group is separately positioned on has 8 135 ⁰or 12 150 ⁰on the two ends of the upper yoke of corner regions and bending inclined-plane and the upper end of two stem stems, each material strip is provided with two opening points, and open butt joint position is by staged interlayer dislocation cycle arrangement, and the iron core stem stem after stack and iron yoke form L-type and interlock.When assembling transformer body, take the method for vertical suit, first three-dimensional iron core upper part opening material strip is pulled down respectively, after mounting coil is inserted on iron core stem stem, take advantage of a situation the insertion of opening material strip group along the guided plate direction be placed on above stem stem, opening material strip group plugs together with the form of docking, takes off guided plate after being plugged, by repetitive operation in above step, with insulating tape, the binding of single frame iron core is fixed after iron core all restores.

Beneficial effect is; 1, iron core of the present invention have employed interlocking structure, improves the mechanical strength of iron core, solves the problem that dismountable transformer core easily loosens, is shifted, is out of shape.

2, open butt joint position is obviously visible, and suit, replacing and maintenance coil are convenient, and plug-in mounting iron core efficiency is high.

3, material strip adopts mechanical automation to produce, and precision is high, production efficiency is high, reduces cost of labor.

Preferably, the opening material strip position of described single frame rectangle iron core be separately positioned on there are 8 135 degree or 12 150 degree of corner regions iron yoke end, on knuckle inclined-plane, stem stem upper end.

Further preferably, described each material strip is to there being two openings, and the material strip opening of frame adjacent bed is by step dislocation cycle arrangement.

Further preferably, described three adopt the two open core of the single frame of wide moulding mixture band and fold-line-shaped material strip with the angle split of 120 degree, central angle, and after split, stem stem cross section is inpolygon.

Further preferably, described three adopt the two open core of the single frame of curve silicon steel material strip with the angle split of 120 degree, central angle, after split stem stem cross section rounded (R type).

Further preferably, described three adopt the two open core of the single frame of wide moulding mixture band with the angle split of 120 degree, central angle, and after split, stem stem cross section is regular hexagon.
