The branch magnetic circuit cores are arranged on two sides of the main core, and two gaps are formed between the main core and the branch magnetic circuit cores. The gaps can be adjusted according to discreteness of coiling the core sheets. The combined annular voltage-regulating transformer core is high in utilizing rate and flexible in design, design and voltage-regulating compensation amount can be adjusted conveniently, the combined annular voltage-regulating transformer core is rapid to adjust, easy to process and low in cost, and is adaptable to various types of voltage-regulating transformers.
Description
Technical field
The utility model relates to a kind of voltage stabilizing transformer iron core, particularly a kind of Combined iron core of ferro resonance AC stabilized transformer.
Background technology
The Combined iron core of existing AC stabilized transformer, when the shape of design iron core steel disc, for reducing leftover pieces, take full advantage of material, be designed to the composite type of E-I type more, as shown in Figure 1, first the both sides diaphragm 3 of lamination and 4 die-cutly got off, become the horizontal yoke sheet of I type, again lamination is cut off from horizontal mid line (dotted line), be divided into two, become the master chip 1 and 2 of two E types, then press shown in Fig. 2, the horizontal yoke sheet of I type and E type master chip are pieced together to the iron core of EI type structure.Although the iron core of this structure has reduced leftover bits, the height of core window depends on the length of horizontal yoke sheet, and the width of window size is subject to again the restriction of horizontal yoke sheet width.Like this, the use occasion of iron core also just is very restricted.And the woollen size of making lamination than iron core actual size, be twice can punching, in production process, cause many fragment datas to recycle.In the fixed situation of transformer efficiency, core section is long-pending to be determined thereupon, as runs into the window coiling and contain while can not receiving any more, this EI shaped iron core must make its master chip size all amplify, whole iron core is strengthened, can cause like this waste of silicon steel sheet material, strengthened cost of manufacture.
Summary of the invention
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part, and provide a kind of simple in structure, the core window size is not limited by horizontal yoke sheet, the convenient iron core diameter that strengthens, elongate window and be convenient to adjust a minute magnetic circuit gap, the Combined annular voltage stabilizing transformer iron core of energy-efficient material-saving.
The purpose of this utility model can reach by following measure:
A kind of Combined annular voltage stabilizing transformer iron core, comprise the transformer main iron core formed by multilayer build-up, and minute magnetic circuit iron core, it is characterized in that, described transformer main iron core is through a multilaminate coiled cylindric main iron core that is laminated into, has the core window of O shape by the banded lamination of bar shaped; Described minute magnetic circuit iron core be the both sides that are located at respectively the cylindric main iron core of this O shape window, by the superimposed minute magnetic circuit iron core that assembles horizontal yoke sheet of the I shape lamination that is provided with fixing hole, leave respectively gap between the cylindric main iron core of each minute magnetic circuit iron core and this O shape window.
The above-mentioned superimposed I shape lamination that assembles minute magnetic circuit iron core, their shape and size size is identical.
The external diameter Φ 1 of the cylindric main iron core of above-mentioned O shape window, equate with the length L of the I shape lamination of described minute magnetic circuit iron core.
The utility model annular voltage stabilizing transformer iron core has advantages of as follows:
1. stock utilization is high, falls the material consumption reduction.Annular core sheet of the present utility model, required loss woollen is few, there is no in process of production leftover pieces, accomplishes to make the best use of everything, and reduces to greatest extent the proportion of goods damageds of silicon steel sheet material.
2. flexible design, conveniently adjust the reduction expense.The utility model core window size is not subject to the restriction of horizontal yoke sheet, and the window diameter can enlarge easily as required or dwindle, and is convenient to adjusted design, has reduced die cost yet, reduces design cost and mould and takes.
3. be convenient to adjust the stabilizing compensation amount, shorten debug time.The discreteness that can reel according to lamination, adjust the gap of minute magnetic circuit, thereby adjust voltage stabilizing.
4. simplicity of design, easily process, and saves time, economizes cost of manufacture.
Below in conjunction with drawings and Examples, the utility model is done the narration of further indefiniteness.
