σ) 1-circle 1 [Prior art] Figures 3 to 1 show examples of conventional external iron type transformers, in which a high voltage coil (2) and a low voltage coil (J

どの手段が採られている。In general, the impedance of a transformer is proportional to the power of the leakage flux density, and increases in proportion to the volume of the space where the leakage flux exists. Therefore, to increase the impedance, increase the number of turns of the coil, or increase the leakage flux density. Shorten the length of the magnetic path through which the magnetic flux passes to increase the leakage magnetic flux density, or;
) Measures have been taken to increase the volume of the space by increasing the distance between the spaces.

ダンスを変更することは、変圧器の構造上きわめて難し
く、新たに変圧器を設計、製作する必要があるという問
題点があった。Conventional static induction devices such as those mentioned above, for example, are used for transformers, and once they are manufactured, it is extremely difficult to change the impedance due to the structure of the transformer, so it is necessary to design a new transformer. , there was a problem in that it required production.
この発明はかような問題点を解消するためになされたも
ので、変圧器などのインピーダンスを、変圧器製作後で
あっても容易に変更し、所定のインピーダンスを得るこ
とができる静止誘導機器を得ることを目的とする。This invention was made to solve these problems, and it provides a stationary induction device that can easily change the impedance of a transformer, etc. even after the transformer has been manufactured, and obtain a predetermined impedance. The purpose is to obtain.
この発明に係る静止誘導機器は、機器内の漏れ磁束の通

る。The stationary induction device according to the present invention includes an iron core block that can be easily taken in and out of the path of leakage magnetic flux within the device.
この発明においては、鉄心ブロックの出し入れによって
漏れ磁束の磁路長が調節され、インピーダンスが変更さ
れる。In this invention, the magnetic path length of leakage magnetic flux is adjusted by moving the iron core block in and out, and the impedance is changed.

配置されている。Figures 1 to q show an embodiment of the present invention, in which an iron core (1
) between the high-voltage coil (2) and the low-voltage coils (3a) and (3b), a plurality of iron core blocks (riga,
Insert freely into and out of the insulating guide (y),
It is located.

乗で増加することになる。According to the above configuration, the iron core blocks (tl) are arranged in the required number according to the desired impedance, and the guides ( By doing this, it becomes easier for leakage magnetic flux to pass through υ, and the magnetic flux density at that part increases in inverse proportion to the magnetic path length, so the magnetic energy due to leakage flux at the part where the iron core block is inserted increases. will increase as the square of the magnetic flux density.

なシ、総じてインピーダンスは大きくなることとなる。However, by placing the iron core block in a part of the space where the leakage magnetic flux exists, the volume occupied by the magnetic energy due to the leakage magnetic flux decreases, but the volume occupied by the magnetic energy due to the insertion of the iron core block l=) decreases. While the decrease is small as the first power of the volume, on the other hand, the magnetic energy increases as the square of the leakage magnetic flux density, so the latter ratio is larger than the former, and the impedance increases overall.
また、インピーダンスを低下させたい場合は、当初挿入

とすることも考えられる。In addition, in the above embodiment, a plurality of core blocks (4) were inserted into the guide individually, but the molded products of the guide and core block were made into a cassette type and the high voltage coil (2)
It is also conceivable to have a structure in which it is inserted between the low voltage coils (ja) and (Jb).
