である。In this figure, (1) is a tank, and (2) is the main body of the induction device housed in the tank, which is composed of an iron core (3) and a winding (4) wound around this iron core. (5)
is an electromagnetic shield attached to the inner surface of the tank, and as shown in Figure 4, a large number of shield plates (6) made by cutting silicon steel strips made of the same material as the iron core (3) into strips are laminated. At the same time, both sides are sandwiched by scissor plates (7) and integrated.
このような構成において、巻線（４）に負荷電流が流れ

、タンク（１）の内面に電磁シールド（５）を装着し、
そのシールド板（６）が漏れ磁束の通路を形成するよう
にしているものである。In such a configuration, when a load current flows through the winding (4), leakage magnetic flux is generated by the current, but if this leakage magnetic flux flows directly through the tank (1), stray loss may increase and the tank To avoid this, an electromagnetic shield (5) is attached to the inner surface of the tank (1).
The shield plate (6) forms a path for leakage magnetic flux.
従来の変圧器は以上のように構成されており一電磁シー
ルド（５）のはさみ板（７）の端面（７Ａ）がエツジ状
となっているため電界集中を生じやすい。The conventional transformer is constructed as described above, and because the end face (7A) of the sandwich plate (7) of the electromagnetic shield (5) is edge-shaped, electric field concentration tends to occur.
従ってこの部分の電界集中を緩和するために、はさみ板
（７）の端面（７Ａ）に面取り加工を施こし。Therefore, in order to alleviate the electric field concentration in this part, the end face (7A) of the scissor plate (7) is chamfered.
第５図に示すように、曲率を大きくして丸みをつけたり
、巻線と電磁シールドとの間の距離を太きくして電界が
集中しないようにしていた。このため電磁シールドの製
作に手間がかかり、又、タンクが大形化するという問題
点があった。As shown in Figure 5, the curvature was increased to make it rounder, and the distance between the winding and the electromagnetic shield was increased to prevent the electric field from concentrating. For this reason, there were problems in that it took time and effort to manufacture the electromagnetic shield, and the tank became large.
この発明はこのような問題点を解消するためになされた

In the figure, (8) is an electrostatic shield provided between the winding (4) and the electromagnetic shield (5) so as to cover the electromagnetic shield (5) - its perspective view is shown in Figure 2. The bottom part (8A) is made by bending a wire mesh and covers the electromagnetic shield placed on the bottom of the tank, and the side part (8A) covers the electromagnetic shield placed on the side of the tank.
8B) and a mounting part (8C) for mounting on the tank.
その他の構成は従来のものと同様であるため説明を省略
する。The rest of the configuration is the same as the conventional one, so the explanation will be omitted.

静電シールド上の電界は十分に小さいものとなる。This embodiment is constructed as described above, and since the electrostatic shield (8) is made of a wire mesh, there is no need to sharply bend the bending part like an edge shape, and the bending part has a smooth surface. Therefore, the electric field on the electrostatic shield becomes sufficiently small.

離についても必要以上に大きく設定しなくてもよい。In addition, since the electromagnetic shield (5) is almost completely shielded from the winding (4) by the electrostatic shield as described above, there is no need to chamfer the end face of the scissor plate (7), and the shape can be freely shaped. It can be done. The separation distance from the winding (4) also does not need to be set larger than necessary.
なお、以上の実施例は、静電シールドによって電磁シー
ルド全体を覆う構成としたが、＊界集中の大きい箇所だ
けを覆うようにしてもよい。In the above embodiments, the electrostatic shield covers the entire electromagnetic shield, but it is also possible to cover only the areas where the field concentration is large.
