本発明は、特許請求の範囲の上位概念部に記載する負荷
時タップ切換器の遮蔽電極に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shielding electrode for an on-load tap changer according to the generic part of the claims.
このような遮蔽電極は通常は鋼管製の遮蔽リングとして
構成される。これは、例えば２つの半殻が互いに押しつ
けられて遮蔽リングになるように溶接される。この場合
、滑らかな表面を達成しなければならないから、溶接部

空気−油交換機能を生じさせないために、油密に溶接す
る必要がある。したがって、製造コストが嵩みこれに加
えて気密試験が必要となる。Such shielding electrodes are usually constructed as shielding rings made of steel tubes. This can be done, for example, by welding two half-shells pressed together to form a shielding ring. In this case, a smooth surface must be achieved, so the weld must be finished flat. Also, in order to prevent the air-oil exchange function of the shielding ring, it is necessary to weld it in an oil-tight manner. Therefore, the manufacturing cost increases and in addition, an airtightness test is required.
なお、遮蔽リングが円形以外の、例えば隋円形または８
角の外形を有する場合に、負荷時タップ切換器内の電位
制御用遮蔽リングの形状にあっては製造コストはさらに
犬となる。このような遮蔽リングは個々の彎曲部材とま
っすぐな管状部材とを組合わせなければならない。鋼材
または鋼管から形成される遮蔽リングのその他の短所は
重量が大となることである。It should be noted that the shielding ring is not circular, for example, Sui circular or 8
In the case of a square profile, the manufacturing costs are even higher when it comes to the shape of the shielding ring for potential control in the on-load tap changer. Such a shielding ring must combine individual curved members and straight tubular members. Another disadvantage of shielding rings made from steel or tubing is their increased weight.
本発明の目的は、上述の遮蔽電極であって、特に円形以
外のリング状であυながら、軽量かつ製造容易な遮蔽電
極を提供することである。An object of the present invention is to provide the above-mentioned shielding electrode, in particular, a shielding electrode that is lightweight and easy to manufacture, although it has a ring shape other than a circle.
この目的は、特許請求の範囲の特徴部に記載した構成に
よって達成される。This object is achieved by the features described in the features of the claims.
本発明によって得られる効果は以下の通シである。この
遮蔽電極は製作容易である。例えば、換気技術および恒
温湿技術等でなじみの波形管を使用することができる。The effects obtained by the present invention are as follows. This shield electrode is easy to manufacture. For example, corrugated tubes familiar from ventilation technology and constant temperature and humidity technology can be used.
この遮蔽電極は極めて軽量にして十分な形状安定性が得
られる。空気−油交換は生じｋい。また円形以外の形状
の形成も極端に容易である。可撓性金属管をある長さに
切断しそして型に適合させて所望の形状に成形される。This shielding electrode can be made extremely lightweight and has sufficient shape stability. Air-oil exchange does not occur. Furthermore, it is extremely easy to form shapes other than circular. The flexible metal tube is cut to length and fitted into a mold to form the desired shape.
金属管の両端は筒状に曲げられた弾性体を両管端に差し

には支持部材および連結部材が打込み取付けられる。Both ends of the metal tube are assembled by inserting an elastic body bent into a cylindrical shape into both tube ends. An aluminum foil strip is wrapped around the joint. A supporting member and a connecting member are attached by driving to the portions to which no electric field is applied.
管は多成分プラスチック発泡体を開口内に適当に充填し

発泡する充填材（シーリングコンパウンド）を充填する
ことも可能である。Good dimensional stability of the tube is achieved by suitably filling the opening with multi-component plastic foam and molding while still hot. The shield electrode is finally wrapped with paper in the usual manner. It is also possible to fill the tube with a foaming filler (sealing compound) before and after integrating the ends of the tube.
