Abstract
The utility model discloses a three-column integral iron core wire winding combined transformer which comprises a coil body. The coil body comprises an iron core (3) and coils (3) wound on the iron core, insulation layers (2) are arranged between the iron core and the coils, the iron core is shaped like a Chinese character 'ri', the iron core is formed by winding band type silicon steel sheets (4), two square internal rings are formed by winding the silicon steel sheets, a rectangular external ring is formed on the two internal rings in a winding mode, and the internal rings and the outer ring are covered with and fixed through insulation paper to form the coil body. Advanced numerical control wire winding equipment is adopted, the integral type iron core is formed by winding the silicon steel sheets, the coils are wound on the integral type iron core, and therefore the integral type iron core transformer is formed in a combined mode, coil combination and processing efficiency is improved, the silicon steel sheets are saved, production cost is lowered, the butt joint faces of the silicon steel sheets can be matched, the clearances between the silicon steel sheets are avoided, and the electrical performance of the transformer is improved.
Description
Technical field
The utility model relates to instrument transformer, especially relates to a kind of integrated iron core coiling combined instrument transformer.
Background technology
Voltage transformer is indispensable a kind of electrical equipment in the transmissions of electricity such as power plant, electric substation and electric power system, and wherein critical piece-coil is comprised of primary winding, secondary coil, iron core and insulating barrier.And insulating barrier is an important parts in voltage transformer coil, its electrical insulation properties height directly affects safety in utilization and the reliability of voltage transformer.Iron core is mostly with silicon steel sheet, to build to add to combine, there is following problem in this combining structure: the one, and silicon steel sheet need to be superimposed as by slices " mouth " font iron core, every one side on square shape iron core four limits is all with connecting into square shape with bolt after the staggered stack of silicon steel sheet, again the synthetic day font of two square shape iron core group, again the coil winding is inserted in iron core column, finally be combined into integral body, take time and effort, working (machining) efficiency is low, processing cost is high, the 2nd, the silicon steel sheet interface stacking up is misfitted, between sheet and sheet, there is space, reduced the electric property of product, conforming product rate is low.
Utility model content
For the existing problem of silicon steel sheet stack combination in above-mentioned prior art, the utility model provides a kind of integral type three cylindricality silicon sheet cores, the combined instrument transformer that is then wound the line and formed by winding on iron core again.
The technical scheme that the technical problems to be solved in the utility model is taked is: described three post integrated iron core coiling combined instrument transformers comprise coil body, described coil body comprises iron core and is wound on the coiling on iron core, between described iron core and coiling, be provided with insulating barrier, described iron core is a day font, and two square inner rings that described silicon-steel sheet used for iron core is entwined and the outer ring being entwined with silicon steel sheet combination are made.
Described in the utility modelly first with silicon steel sheet, be coiled into two square inner rings, then be wound around and make rectangular outer ring on inner ring, with insulating paper by inner ring and the outer ring formation coil body that is coated and fixed.
The utility model adopts advanced numerical control spooling equipment, first with silicon steel sheet, turn to integral type iron core, coiling coiling on integral type iron core again, thereby be combined into integral type iron core instrument transformer, both improved coil combination working (machining) efficiency, saved silicon steel sheet, reduced production cost, can make again silicon steel sheet interface coincide, avoid occurring between silicon steel sheet space, improve the electric property of instrument transformer.

Fig. 2 is plan structure schematic diagram of the present utility model,
Fig. 3 is the A-A sectional structure schematic diagram of Fig. 2.
Coiling 2, insulating barrier 3, iron core 4, silicon steel sheet in the drawings, 1.
Embodiment
At Fig. 1, in Fig. 2 and Fig. 3, the utility model comprises coil body, described coil body comprises iron core 3 and is wound on the coiling 1 on iron core, between described iron core and coiling, be provided with insulating barrier 2, described iron core is a day font, iron core is formed by two square inner rings and the outer ring being wrapped on two inner rings, inner ring and outer ring are entwined with silicon steel sheet 4, according to the specification of instrument transformer, determine thickness (number of plies being wound around) and the width of inner ring, choose certain width, the silicon steel sheet of total length and thickness, on coil winding machine, first silicon steel sheet is wound in to square inner ring, again by two square inner rings adjacent being fixed on another coil winding machine side by side, two inner ring outer felt on this coil winding machine are around outer ring again, after the coiling of outer ring, with exhausted insulating paper, inner ring and outer ring are coated and fixed and form the all-in-one-piece iron core 3 of day font, again integral type iron core is fixed on coil winding machine, on three minor faces of iron core of day font, put three insulating barriers 2 again, on insulating barrier, coiling forms coiling 1 respectively again, on coiling, coated insulation paper forms knockdown instrument transformer again.
Claims (1)
