【発明の詳細な説明】
この発明は巻線の外周に電界緩和用のシールドリングを
有する変成器の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a transformer having a shield ring around the outer periphery of the winding for mitigating an electric field.
一般に計器用変成器等のように高圧側の電圧が非常に高
い変成器においては、高圧巻線の巻数は極端に大きくな
るので、低圧巻線の外側に巻回された高圧巻線は巻心に
対して高く積層されることになる。Generally, in transformers such as instrument transformers where the voltage on the high voltage side is very high, the number of turns of the high voltage winding is extremely large, so the high voltage winding wound outside the low voltage winding is This means that they will be stacked high against each other.
そして、積層された最外層の巻線とブッシング間を導体
で接続し、ブッシング高電圧母線とが接続されるように
構成されている。The stacked outermost layer winding and the bushing are connected by a conductor, and the bushing is connected to a high voltage bus bar.
また、積層され巻心から大きく突出した形状を有する巻
線においては、巻線の最外周の全周を被ったシールドリ
ングを設けて、巻線端部の電界を緩和させ対接地間及び
巻線相互間の絶縁設計を容易にするように工夫されてい
る。In addition, for laminated windings that have a shape that protrudes greatly from the winding core, a shield ring that covers the entire outermost circumference of the windings is provided to alleviate the electric field at the ends of the windings and between the windings and between the windings. The design has been devised to facilitate the insulation design between the two.
特に密閉形開閉装置に具備され高気圧の絶縁ガス中で使
用される変圧器ではシールドリングを有効に利用するこ
とによって、密閉形開閉装置の小形化を図ることができ
る。In particular, in a transformer included in a closed switchgear and used in a high-pressure insulating gas, the shield ring can be effectively used to reduce the size of the closed switchgear.
従来の変成器は第１図に示すように、巻心１に巻回され
た巻線２の最外周に銅板等の金属板３を巻き、金属板３
の両端に円形状のリング６を固着することによって巻線
２のシールドがなされている。As shown in FIG. 1, a conventional transformer has a metal plate 3 such as a copper plate wrapped around the outermost circumference of a winding 2 wound around a core 1.
The winding 2 is shielded by fixing circular rings 6 to both ends of the winding 2.
この場合、巻心１に積層された巻線２を増し締めするた
めに、金属板３を介してバインドテープ５等で緊縛され
ている。In this case, in order to further tighten the winding 2 laminated on the winding core 1, the winding 2 is bound with a bind tape 5 or the like via a metal plate 3.
しかし、金属板３に固着されたリングの剛性が高いので
、増し締めを行なったとき金属板と巻線外周とが密着し
ないためノングの固定が困難であり、又、金属板３の内
径と巻線２の最外周部外径とがほぼ一致しているため、
金属板３を巻線２に挿入する作業が非常に困難である等
の欠点があった。However, since the ring fixed to the metal plate 3 has high rigidity, the metal plate and the outer periphery of the winding do not come into close contact when retightening, making it difficult to fix the nongang. Since the outer diameter of the outermost part of line 2 is almost the same,
There were drawbacks such as the extremely difficult work of inserting the metal plate 3 into the winding 2.
この発明は上記欠点を解消するためになされたものでシ
ールドリングの分割部を形成する対向面に一対の端板を

ことを目的としている。This invention was made in order to eliminate the above-mentioned drawbacks, and by providing a pair of end plates on opposing surfaces forming the divided portion of the shield ring and fastening the end plates with a fastening member, the winding can be easily connected to the winding. It is an object of the present invention to provide a transformer that can be sufficiently tightened and that the shield ring can be inserted easily and reliably.
以下、この発明における変成器の一実施例を第２図ない

最外周部に固着する。In one embodiment configured in this manner, the shield ring 7 has a width of the gap formed between the end plates 8 and 9 as shown in FIG. Since they are configured respectively, the shield ring 7
is inserted into the outer periphery of the winding 2, and by tightening the bolt 11 and nut 15 from the hole 16, the shield ring 7 is reduced and deformed within the elastic limit, and the width of the gap is changed from T1+α to T1, and the inner diameter is changed from D1- to Dl. The coils are respectively contracted and fixed to the outermost periphery of the winding 2.
固着を完了した最終状態におけるシールドリング７の寸
