Abstract

The invention discloses a folding type planar one-phase open transformer core. The folding type planar one-phase open transformer core comprises a transformer core body provided with an L-shaped interlocking structure, wherein the transformer core body is composed of a one-phase core, and the section of the core body is in the shape of an inscribed polygon of a circle, or a circle (R type), or a rectangle or a long circle; a one-frame core is composed of a plurality of sets of rectangular open material straps arranged in a rectangular corner area, the butt joints of the openings of the material straps are located at the two ends of an upper yoke, the two bevels of the rectangle and the upper ends of two stems. The folded core stems and the yoke are interlocked, so that the mechanical strength of the core is improved. Therefore, the core has the advantages of being low in consumption, low in noise, high in sudden short circuit resistance and high in production efficiency.

Description

The single-phase opening transformer core of foldable plane

Technical field

The invention belongs to transformer technology field, particularly the single-phase opening transformer core of a kind of foldable plane.

Background technology

Transformer core is the vitals of composition transformer, and the kind of transformer can be divided into single-phase transformer and three-phase transformer.In recent years, along with country is to the popularization of energy-conserving product, a kind of energy-saving effect is significantly removable have lightweight, volume is little, no-load loss is little, manufacturing process is simple, single noise is low, good energy-conserving effect, heat radiation and overload capacity is strong, compact conformation, machinery and electric property the are superior single-phase opening transformer core of foldable plane are widely used.Nonetheless, 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 plug-in mounting upper yoke, not only have impact on iron core performance, also reduce integrated transformers quality.Therefore, how technologic improvement is carried out to existing flat surface transformer iron core, improve mechanical strength, become the target that people expect.

Summary of the invention

To achieve these goals, to overcome and the deficiency that makes up in prior art and defect.The invention provides the single-phase opening transformer core of a kind of foldable plane.It can not only improve the mechanical strength of iron core, is more embodied in transformer itself and has the advantages 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 foldable plane single-phase opening transformer core, it comprises and being made up of a single frame iron core, and single frame iron core is provided with many group opening material strip groups, and the material strip open butt joint position of 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 iron core upper part opening material strip (being the upper yoke of iron core) is pulled down respectively, after mounting coil is inserted on iron core stem stem, opening material strip group inserted successively 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, be finally closed into a day font.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, the visible obviously seam points in open butt joint position, 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, described single frame rectangle inner ring iron core and iron core opening material strip position, outer ring 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, the iron core stem stem cross section after the single frame rectangle inner ring iron core of described employing wide moulding mixture band and fold-line-shaped material strip and outer ring iron core split is oval polygon.

Further preferably, the iron core stem stem cross section after the single frame rectangle inner ring iron core of described employing curve silicon steel material strip and outer ring iron core split is inpolygon.

Further preferably, the iron core stem stem rectangular in cross-section after the single frame rectangle inner ring iron core of the wide moulding mixture band of described employing and outer ring iron core split.

Further preferably, the iron core stem stem cross section rounded (being R type) after the single frame rectangle inner ring iron core of described employing wide moulding mixture band and outer ring iron core split.
