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 providing a kind of simple in structure, core window is not limited by horizontal yoke, can amplify easily core length, elongate window and adjust a minute magnetic circuit gap, being convenient to the composite type window voltage stabilizing transformer iron core of design modifying.

The purpose of this utility model can reach by following measure:

A kind of composite type window voltage stabilizing transformer iron core, be a kind of, transformer core of being spliced into tool rectangular window superimposed by the multilayer lamination, it is characterized in that the transformer core of described tool rectangular window, by being provided with fixing hole, a F shape iron core that bed thickness is identical, an I ₁Strip iron core, an I ₂Billet shape iron core and an I ₃Block iron core, be assembled into tool large rectangle window W through splicing ₁With little rectangular window W ₂Transformer core, wherein have a large rectangle window W ₁Part form the main magnetic circuit of transformer core, the little rectangular window W of tool ₂Part form minute magnetic circuit of iron core; Be provided with gap at this minute on the magnetic circuit iron core.

Above-mentioned large rectangle window W ₁With little rectangular window W ₂, their width dimensions equates.

Above-mentioned F shape iron core is provided with fixing hole, I ₁Strip iron core (21) is provided with fixing hole, I ₂Billet shape iron core is provided with fixing hole.

The utility model voltage stabilizing transformer iron core has advantages of as follows:

1. window area is not limited by horizontal yoke, is convenient to design modifying.The utility model iron core, can arbitrarily elongate the length of window or shorten according to the actual needs on engineering, simplified the design of iron core, reduces design cost and mould and take.

2. stock utilization is high.The utility model iron core is by F shape lamination and the strip iron core sheet is superimposed is combined into, and can significantly reduce the width of woollen, and the die cutting die of leftover pieces in being fully used, producing becomes simply, can reduce the punch press tonnage, saves energy.

3. install, debug easy, simplicity of design.This lamination is disposable machining, and can adjust minute magnetic circuit gap in order to adjust the compensation rate of transformer according to superimposed discreteness, reaches that voltage stabilizing is consistent, precision good, shortens debug time.And due to simplicity of design, be easy to processing, save time, reduce costs, be specially adapted to the voltage stabilizing transformer of single-phase high-power.

Below in conjunction with drawings and Examples, the utility model is done the narration of further indefiniteness.
