Description
【発明の詳細な説明】 この発明は、誘導機器用鉄心に関する。[Detailed description of the invention] The present invention relates to an iron core for induction equipment.
非晶質磁性箔体を用いて変圧器等の大型の鉄心
を製作する場合、非晶質磁性箔体が薄く、取り扱
いにくいので、積層作業が悪く、従つて、通常は
けい素鋼板と組み合わせた複合鉄心として使用す
ることが多い。 When manufacturing large cores such as transformers using amorphous magnetic foil, the lamination process is difficult because the amorphous magnetic foil is thin and difficult to handle, so it is usually combined with silicon steel sheets. Often used as a composite core.
従来、この種の複合鉄心としては、第１図のご
とく、必要形状に切断された非晶質磁性箔体２を
けい素鋼板１に１枚毎に接着剤３を使用して、縦
方向に貼りつけるとともに、幅方向にも並べて貼
りつけて構成していた。 Conventionally, as shown in Fig. 1, this type of composite core has been manufactured by attaching an amorphous magnetic foil 2 cut into the required shape to a silicon steel plate 1 using an adhesive 3 for each piece in the longitudinal direction. It was constructed by pasting them together and also pasting them side by side in the width direction.
そのため、非晶質磁性体２の切断と、その接着
作業に多大な時間を要していた。 Therefore, cutting the amorphous magnetic material 2 and adhering the same require a lot of time.
また、接着剤３を使用する関係から、鉄心の占
績率が低下し、鉄心断面積が増大するので、誘導
機器の寸法及び重量にまで影響を及ぼすものであ
つた。 Furthermore, since the adhesive 3 is used, the occupancy rate of the core decreases and the cross-sectional area of the core increases, which also affects the dimensions and weight of the induction device.
また、非晶質磁性箔体２の特性を有効に利用す
るには、高温による複合鉄心の焼鈍が必要である
が、接着剤３を使用しているため、焼鈍に必要な
温度まで上昇できない状態であつた。 In addition, in order to effectively utilize the characteristics of the amorphous magnetic foil 2, it is necessary to annealing the composite core at a high temperature, but since the adhesive 3 is used, the temperature cannot be raised to the required temperature for annealing. It was hot.
この発明は、上記の実情に鑑みてなされたもの
で、けい素鋼板の磁束の流れの方向に一致させ
て、上記けい素鋼板を巻芯として非晶質磁性箔体

績率を高め、また焼鈍が可能な誘導機器用鉄心を
提供することを目的とする。 This invention has been made in view of the above-mentioned circumstances, and consists of multiple layers of amorphous magnetic foil in the width direction, using the silicon steel plate as a winding core, in alignment with the direction of magnetic flux flow in the silicon steel plate. The purpose of the present invention is to provide an iron core for induction equipment that can increase the occupancy rate by winding the iron core and can be annealed.
以下、図について説明する。 The figures will be explained below.
第２図において、本発明による複合鉄心は、巻
芯となるけい素鋼板１の長手方向に、薄く、かつ
幅の狭いケープ状の非晶質磁性箔体２を、幅方向

のである。この巻きつけの方法としては、第３図
ａあるいはｂのように、突き合せあるいは1/2重
ね巻きの方法により容易に製作可能である。 In FIG. 2, the composite core according to the present invention is constructed by wrapping thin and narrow cape-shaped amorphous magnetic foils 2 in the longitudinal direction of a silicon steel plate 1 serving as the winding core in a row in the width direction. It is wrapped in multiple layers. As for this winding method, as shown in FIG. 3a or b, it can be easily produced by butt or 1/2 overlap winding method.
このように、非晶質磁性箔体２をけい素鋼板２
に巻きつけていくことにより、非晶質磁性箔体と
けい素鋼板及び磁性非晶質磁性箔体同士間には、
所定の面圧が得られる。しかし、非晶質磁性箔体

状態で焼鈍を行い、空隙をなくし、相互間を密に
する。また、この焼鈍により、非晶質磁性箔体の
特性を改善することができる。 In this way, the amorphous magnetic foil 2 is attached to the silicon steel plate 2.
By wrapping the amorphous magnetic foil around the silicon steel plate and the magnetic amorphous magnetic foil,
A predetermined surface pressure can be obtained. However, gaps also exist between the amorphous magnetic foil and the silicon steel plate and between the magnetic amorphous magnetic foils. For this reason, after winding the amorphous magnetic foil, annealing is performed while a predetermined surface pressure is obtained, thereby eliminating voids and making the spaces denser. Furthermore, this annealing can improve the characteristics of the amorphous magnetic foil.
このようにして製作された複合鉄心の単体は、
第４図のように複数積み重ね、バインダで周囲を
締め付け固定して誘導機鉄心として使用される。
ここで、複合鉄心単体の非晶質磁性体の巻き終わ

ねる。 The single composite core manufactured in this way is
As shown in Fig. 4, a plurality of them are stacked, the periphery is tightened and fixed with a binder, and used as an induction machine core.
Here, the end portion of the amorphous magnetic material of the single composite core is stacked so that it does not reach the outer periphery when stacking.
なお、巻芯としては、けい素鋼板１を複数枚重
ねたものを使用しもよい。 Note that a plurality of stacked silicon steel plates 1 may be used as the winding core.
以上のように、この発明では、けい素鋼板に非
晶質磁性箔体を幅方向に並べかつ積層して巻きつ

能となり、非晶質磁性箔体の特性を有効に利用で
きる。 As described above, in this invention, amorphous magnetic foils are arranged in the width direction around a silicon steel plate, laminated and wound, and then annealed while a predetermined surface pressure is obtained. Since a wide composite core can be manufactured easily and quickly, manufacturing costs can be reduced and the core occupancy rate can be improved. Furthermore, since no adhesive is used, it is possible to increase the temperature for annealing, and the characteristics of the amorphous magnetic foil can be effectively utilized.
また、複合鉄心は積層された状態で使用される
ので、非晶質磁性箔体の巻端は完全に固定され
る。そのため、端末処理などは一切不要であるな
どの多くの効果を奏する。 Furthermore, since the composite core is used in a laminated state, the winding ends of the amorphous magnetic foil are completely fixed. Therefore, there are many advantages such as no terminal processing required.
