Description
本発明は、鉄心構造が改善されたリアクトルや変圧器などの静止電磁機器に関するものである。
The present invention relates to a stationary electromagnetic device such as a reactor or a transformer having an improved iron core structure.
リアクトルや変圧器などの静止電磁機器において、その鉄心を構成する場合、珪素鋼板を型抜きし、積層することによって成形していたが、珪素鋼板は鉄損が大きい、磁歪が大きく騒音が出る等の問題点があった。そこで鉄損・磁歪の小さなアモルファスやファインメット（日立金属の登録商標）等の薄膜導体を用いて鉄心を構成する技術が開発されている。
In static electromagnetic equipment such as reactors and transformers, when forming the iron core, the silicon steel sheet was formed by die cutting and stacking, but the silicon steel sheet has a large iron loss, a large magnetostriction, and a noise. There was a problem. Therefore, a technique for forming an iron core using a thin film conductor such as amorphous or finemet (registered trademark of Hitachi Metals) with small iron loss and magnetostriction has been developed.
アモルファスやファインメット等の薄膜導体で鉄心を構成する場合、薄膜導体を巻型に複数回巻き付けることにより成形することになり、成形後の鉄心は円周方向に積層された中空状の鉄心となる。そのため、リアクトルや変圧器に用いる鉄心は、中空状の鉄心を複数組み合わせた構成にして製作している。
When an iron core is composed of a thin film conductor such as amorphous or fine met, it will be formed by winding the thin film conductor around the winding mold multiple times, and the iron core after forming will be a hollow core laminated in the circumferential direction. . Therefore, iron cores used for reactors and transformers are manufactured by combining a plurality of hollow iron cores.
特許文献１には、円周方向に積層された中空状の鉄心を用いるリアクトルや変圧器などの静止電磁機器の一例が記載されている。
Patent Document 1 describes an example of a stationary electromagnetic device such as a reactor or a transformer using hollow iron cores stacked in the circumferential direction.
特許文献１に示された従来の円周方向に積層された中空状の鉄心を、図１２に示す。図１２ａは２脚鉄心を示しており、円周方向に積層した１つの鉄心１の２つの脚部１Ｌに巻線（図示せず）を施して単相の静止電磁機器を構成する。なお、必要に応じて積層鉄心の一部にギャップ調整部７を設けることがある。図１２ｂは３脚鉄心を製作したときの例であり、円周方向に積層した２つの鉄心１の脚部１Ｌ同士を隣接して配置して３組の脚部を構成し、ここに３組の巻線（図示せず）を施して３相の静止電磁機器を構成する。
FIG. 12 shows a conventional hollow iron core laminated in the circumferential direction shown in Patent Document 1. As shown in FIG. FIG. 12a shows a two-leg iron core, and windings (not shown) are applied to two leg portions 1L of one iron core 1 laminated in the circumferential direction to constitute a single-phase stationary electromagnetic device. In addition, the gap adjustment part 7 may be provided in a part of laminated iron core as needed. FIG. 12b shows an example when a three-legged iron core is manufactured. Three leg portions 1L of two iron cores 1 laminated in the circumferential direction are arranged adjacent to each other to form three leg portions. Windings (not shown) are provided to form a three-phase stationary electromagnetic device.
この結果、３以上の脚数を持つ鉄心を製作する場合、２脚鉄心を複数組み合わせることとなり、形状に制限があった。例えば図１２ｂの図形の静止電磁機器は、横幅が大きく奥行きが狭い為、装置として収納するには、収納性に問題がある。
As a result, when manufacturing an iron core having three or more legs, a combination of two or two leg iron cores was required, and the shape was limited. For example, the static electromagnetic device shown in FIG. 12b has a large width and a narrow depth, so that there is a problem in storage property when it is stored as a device.
本発明は上記の欠点を改善するために提案されたもので、その目的は、鉄心構成の自由度を向上することにある。

In order to achieve the above object, the present invention provides a plurality of hollow iron cores formed in a hollow shape, and a plurality of rod-shaped iron cores installed so as to confront the hollow surfaces between the plurality of hollow iron cores. Is a static electromagnetic device in which a part of the iron core is wound.

さらに、中空状鉄心と同心軸上に冷却器を備えるのがよい。

本発明によれば、薄膜導体で製作した巻鉄心を用い、任意脚数の鉄心を収納性に優れた構成にて製作可能となる。
According to the present invention, an iron core with an arbitrary number of legs can be manufactured with a configuration excellent in stowability using a wound iron core manufactured with a thin film conductor.
以下、本発明の実施例について図を用いて詳細に説明する。
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a first embodiment of the present invention. In the figure, 1 is a hollow wound core having a hollow central portion, 2 is a rod-shaped wound core, and is composed of two hollow wound cores 1a and 1b facing the hollow surface of the hollow wound core. In this example, for example, four rod-shaped iron cores 2 are arranged between the four iron cores. The hollow iron cores 1a and 1b and the rod-shaped iron core 2 are each formed by laminating thin film conductors in the radial direction. When this iron core is used as a transformer or a reactor, four rod-shaped wound iron cores 2 are concentrically wound.
また、係る形状の鉄心を備えた静止電磁機器において、磁気抵抗を任意の値に調整するときには、中空状鉄心１ａ、１ｂと、棒状鉄心２の接続部を、ギャップ調整部３として利用することができる。例えば、ギャップ調整部３において完全に接着する、または絶縁物を挟んで接着する、さらには空隙を入れることによりギャップを設けてもよい。
Further, in a static electromagnetic device including an iron core having such a shape, when adjusting the magnetic resistance to an arbitrary value, the connecting portion between the hollow iron cores 1a and 1b and the rod-shaped iron core 2 can be used as the gap adjusting portion 3. it can. For example, the gap may be provided by completely adhering in the gap adjusting unit 3 or adhering with an insulator interposed therebetween, and further by providing a gap.
図２は、本発明の第２の実施例を示す。第１の実施例と同じ部分には同じ記号を用いている。ここでは図１の実施例と異なり、棒状鉄心２を二段に重ね、２脚の鉄心を構成したものを示す。この場合には、棒状鉄心２を重ねる箇所にギャップ調節部４が存在するので、この部分を適宜完全に接着する、または絶縁物を挟んで接着する、さらには空隙を入れるなどの対策を施すことにより、ギャップを調整可能である。図２の実施例によれば、棒状鉄心２を少なくとも２個以上重ねることにより、ギャップを設ける場所を任意に製作可能である。
FIG. 2 shows a second embodiment of the present invention. The same symbols are used for the same parts as in the first embodiment. Here, unlike the embodiment of FIG. 1, a rod-shaped iron core 2 is overlapped in two stages to form a two-legged iron core. In this case, since the gap adjusting portion 4 is present at the place where the rod-shaped iron core 2 is overlapped, measures should be taken such as completely adhering this portion as appropriate, or adhering with an insulating material, and further providing a gap. Thus, the gap can be adjusted. According to the embodiment of FIG. 2, a place where a gap is provided can be arbitrarily manufactured by stacking at least two bar-shaped iron cores 2.
図３は、本発明の第３の実施例を示す。第１、２の実施例と同じ部分には同じ記号を用いている。図３の実施例では例えば２脚鉄心構成とするが、その場合に１脚は棒状鉄心２ｂを３つ重ねたものとし、もう１脚は１つの棒状鉄心２ａを用いることで鉄心を構成している。なお、棒状鉄心２ａにおいては、１つの棒状鉄心で構成する必要はなく、他脚と同様に分割してもよい。棒状鉄心２ｂを重ねた箇所において、ギャップ調節部４が存在し、完全に接着する、または絶縁物を挟む、または空隙を入れることによりギャップを調整可能である。
FIG. 3 shows a third embodiment of the present invention. The same symbols are used for the same parts as in the first and second embodiments.

In that case, one leg is formed by stacking three bar-shaped iron cores 2b, and the other leg is configured by using one bar-shaped iron core 2a. Yes. In addition, in the rod-shaped iron core 2a, it is not necessary to comprise with one rod-shaped iron core, and you may divide | segment similarly to other legs. The gap adjusting portion 4 is present at the place where the rod-shaped iron cores 2b are overlapped, and the gap can be adjusted by completely adhering, sandwiching an insulator, or inserting a gap.
このように棒状鉄心を少なくとも２個以上重ねたものと、１つ以上の棒状鉄心を用いて脚を構成することにより、ギャップを設ける場所を任意に製作可能である。なお、任意のギャップにできるということは、この鉄心を用いてリアクトルや変圧器などの静止電磁機器を構成する場合に、任意のＢ－Ｈ特性曲線が得られるということである。
</ RTI> Thus, by constructing legs using at least two bar-shaped iron cores and one or more bar-shaped iron cores, it is possible to arbitrarily manufacture a place where a gap is provided. The fact that an arbitrary gap can be achieved means that an arbitrary BH characteristic curve can be obtained when a static electromagnetic device such as a reactor or a transformer is configured using this iron core.
図４は、本発明の第４の実施例を示す。第１～３の実施例と同じ部分には同じ記号を用いている。本実施例では図２に対し、中空状鉄心１ｃが１つ追加されて、三段構成とされている。本実施例では中空状鉄心１を３個、棒状鉄心２を４個使用し、２脚の鉄心を構成したものを示す。中空状鉄心１ｃと上下の棒状鉄心の間にもギャップ調節部３が存在する。この部位においても、完全に接着する、または絶縁物を挟む、または空隙を入れることによりギャップを調整可能である。このような構成にすることにより、実施例２、３と異なる方法によりギャップを設ける場所を任意に製作可能である。

The magnetic material used at this time may be not only a thin film conductor such as amorphous or fine met, but also a laminated silicon steel plate or a dust core. Moreover, it can contribute to size reduction by using the iron core of this invention as circuit structural members, such as a power converter.
本発明によれば、収納性に優れた静止電磁機器が実現できるので、幅広い分野の静止電磁機器に適用可能である。
According to the present invention, it is possible to realize a stationary electromagnetic device with excellent storage properties, and therefore it can be applied to stationary electromagnetic devices in a wide range of fields.
