Description
【考案の詳細な説明】
この考案は、その表面を何段かに分けた絶縁物で覆うこ
とにより絶縁耐力を向上させた油中シールド電極の構造
に関するものである。[Detailed description of the invention] This invention relates to the structure of an oil-submerged shield electrode whose dielectric strength is improved by covering its surface with an insulating material divided into several stages.
従来の油中シールド電極は第1図ないし第3図に示すよ
うに電極導体1の表面にクレープ紙からなるテーピング
層2で覆って絶縁を保持している。In a conventional oil-submerged shield electrode, as shown in FIGS. 1 to 3, the surface of an electrode conductor 1 is covered with a taping layer 2 made of crepe paper to maintain insulation.
しかしながら、この種電極は、その表面上の電位傾度が
油絶縁に耐え得るものでなければならないので、使用電
圧が高くなり電極表面の電位傾度が大きくなると、電極
導体1の形状をより大きなものにして電位傾度を下げる
か、油中絶縁距離を必要以上に大きくとらなければなら
ないので、変圧器自身の外形が大きくなるという欠点が
あった。However, this type of electrode must have a potential gradient on its surface that can withstand oil insulation, so as the voltage used increases and the potential gradient on the electrode surface increases, the shape of the electrode conductor 1 must be made larger. Therefore, the potential gradient must be lowered or the distance of insulation in oil must be made larger than necessary, which has the disadvantage of increasing the external size of the transformer itself.

極を提供することを目的としたものである。This idea was developed to eliminate the above-mentioned drawbacks of the conventional method, and by alternately covering the electrode conductor surface with a taping layer made of crepe paper and a corrugated presspod layer, the dielectric strength was improved. The object of the present invention is to provide an oil-submerged shield electrode that can be improved and the external shape of the transformer itself can be made more compact.
以下、この考案の一実施例を第4図および第5図に基づ
いて説明する。An embodiment of this invention will be described below with reference to FIGS. 4 and 5.

プ紙からなるテーピング層2とコルゲートされたプレス
ポード層3で交互に被覆されている。In the figure, an electrode body 1 is the same as the conventional one, but its surface is alternately covered with a taping layer 2 made of crepe paper and a corrugated presspod layer 3.
このプレスポード層3はコルゲートされ所定の幅をとっ
たプレスポードを積層したものである。This press pod layer 3 is a stack of corrugated press pods each having a predetermined width.

出来る。In the oil-submerged shield electrode according to an embodiment of the invention configured as described above, the presspod layer 3 is placed between the taping layers 2 serving as an insulating barrier to maintain appropriate spacing, thereby making it possible to finely divide the oil gap. The taping layer 2, which becomes an insulating barrier depending on the magnitude of the potential gradient, can create a barrier and strengthen the dielectric strength more effectively.
By increasing or decreasing the number of layers, the insulation can be strengthened to suit each usage condition without changing the size of the electrode conductor 1.
