Therefore, there is a possibility that the transportation size and weight will not be met. In addition, when installing in an underground substation,
There is a limit on the size of the entrance, and there is a possibility that it will be exceeded.

ル機能を持つ主脚鉄心６ａと巻線１０ａとを配置した。It should be noted that the same parts as in the prior art have been given the same reference numerals, so their explanation will be omitted. In this embodiment, the main landing gear core 1a, the transformer winding 5
, a space between the transformer winding 5 and the side leg 4b formed by extending the upper and lower yokes 2a, 3a of a single-phase transformer equipped with the upper and lower yokes 2a, 3a, and the side legs 4a, 4b. A main landing gear core 6a having a reactor function and a winding 10a are arranged.

。By doing this, the upper and lower yokes 2a of the transformer
, 3a and side leg 4b are now used as each yoke and side leg of the reactor, making it possible to significantly reduce the size and weight, and easily install it in buildings and underground substations in urban areas. It is possible to obtain a transformer with a built-in reactor.

。That is, the upper and lower yokes 2a and 3a of the transformer are extended, the inside of the core window is expanded, and the core block 6a and the reactor winding 10a having a reactor function are arranged. At this time, the main leg portion 12 of the reactor has a structure in which iron core blocks 6a and voids 13 are stacked alternately (see Fig. 1).

省略しである。FIG. 2 is a connection diagram when the single-phase converter is configured in a punctured configuration, FIG. 3 is a simplified equivalent circuit diagram, and FIG. 4 is a vector diagram thereof. For simplicity, excitation current, leakage impedance, etc. are omitted.

される磁気回路中では同一方向に流れることを意味する
。-For the next side applied voltage ■1, the main magnetic flux ΦT generated is 90
'The phase is delayed, and the secondary induced voltage E on the transformer side is further delayed in phase by 90 degrees with respect to the main magnetic flux ΦT. When the terminal of the reactor winding 10a (see Fig. 1) is connected to this secondary induced voltage E, the main magnetic flux ΦX of the reactor will be delayed in phase by 900 with respect to E2, so that it will eventually become as shown in the vector diagram in Fig. 4. Main magnetic flux ΦT of transformer and main magnetic flux ΦX of reactor
is in the opposite direction. This means that, as shown in FIG. 1, the air flows in the same direction in the magnetic circuit composed of the main leg iron core la, the upper and lower yokes 2a and 3a, and the side legs 4a and 4b.
従って変圧器の主磁束ΦＴのうちΦＴ ／ ２はリアク

面積Ｓ２は上、下ヨーク２ａ、３ａの断面積Ｓ、のΦ−
Ｔ／ΦＴに縮小することができる。Therefore, ΦT/2 of the main magnetic flux ΦT of the transformer is divided into the core legs of the reactor by an amount of ΦX. The remaining magnetic flux Φ′
T=(ΦT/2−Φ) will flow through the side leg 4b. From this, the cross-sectional area S2 of the side leg 4b on the reactor side is Φ-
It can be reduced to T/ΦT.
このように本実施例によれば、変圧器の巻線と側脚間の
窓内空間にリアクトルを挿入した構造としたため、側脚

形化、重量の低減並びに損失の低減を実現することがで
きる。In this way, according to this embodiment, the structure is such that the reactor is inserted into the space within the window between the transformer windings and the side legs, so the number of side legs is reduced, the cross-sectional area of the side legs is also reduced, and the overall It is possible to achieve smaller dimensions, lower weight, and lower losses.

脚部１２に空隙１３があるので、磁気抵抗が大きいため
変圧器の主磁束ΦＴの約１／２が側脚４ｂを通ることに
なる。In the above embodiment, the reactor is always connected, but in this embodiment, as shown in FIG. It is. When the reactor is connected, the same phenomenon as described above occurs, but when the reactor is disconnected, there is a gap 13 in the reactor main leg 12, so the magnetic resistance is large, so the main magnetic flux ΦT of the transformer is approximately 1/2 will pass through the side leg 4b.
また、上記は変圧器巻線がスター／デルタ−の二巻線構

に、巻線が３個以上あっても現象は全く同一である。す
なわち本実施例は変圧器の三次巻線５ｃとリアクトル巻
線１０ａとの間に開閉器１４を設けたものである。Additionally, the above is for the case where the transformer winding has a star/delta two-winding structure, but as shown in Figures 6 and 7, the phenomenon does not occur even if there are three or more windings. They are exactly the same. That is, in this embodiment, a switch 14 is provided between the tertiary winding 5c of the transformer and the reactor winding 10a.
さらに第８図はリアクトル主脚部１２を全くの空心とし
た空心形リアクトルとした場合である。Further, FIG. 8 shows a case where the reactor main leg portion 12 is an air-core type reactor in which the reactor main leg portion 12 is completely air-centered.
この場合も前述の場合と同様な作用効果を奏することが
できる。In this case as well, the same effects as in the above case can be achieved.
