【考案の詳細な説明】 この考案は変圧器用コイル、回転機用等に用いられる平
角絶縁電線の改良に関する。
[Detailed Description of the Invention] This invention relates to improvements in rectangular insulated wires used for transformer coils, rotating machines, etc.

この種の絶縁電線としては、平角導体に絶縁テープをそ
の側縁が重なるように横巻きしたものに代えて、両側縁
が互に重なるように縦沿えしたものが注目されている。
As an insulated wire of this type, instead of one in which an insulating tape is wound horizontally around a rectangular conductor so that the side edges thereof overlap, a type in which the insulating tape is laid vertically so that both side edges overlap each other is attracting attention.

しかし斯かる構成では導体のエッヂ方向の絶縁が薄くな
るためこれをコイルとした場合、ターン間の絶縁破壊強
度が小さく信頼性に欠けるという問題がある。
However, in such a configuration, the insulation in the edge direction of the conductor becomes thinner, so when this is used as a coil, there is a problem that the dielectric breakdown strength between turns is low and reliability is lacking.

This idea was made based on this point, and its gist is that insulating tape is placed on a rectangular conductor cut out from two flat faces and two edge faces so that both edges overlap each other. A rectangular insulated wire, which is characterized in that an inner layer insulating tape is arranged vertically so as to continuously cover three surfaces, two flat surfaces directly above the rectangular conductor and two edge surfaces, in a rectangular insulated wire formed by vertically oriented wires. It's on the wire.

That is, as a result of intensive study by the inventors of the present application on improving the insulation strength of the edge surface, which is a drawback of vertical winding, the inventors of the present invention have developed a method that continuously covers three surfaces: the flat surface directly above the rectangular conductor and the two edge surfaces. It has been discovered that the insulation strength of the edge surface can be significantly improved by arranging the insulating tape vertically as shown in FIG.

換言すれば、エツジ面の絶縁強度は平角導体のエツジ面
直上にのみ内層絶縁テープを増加配置したのでは向上す

続的に覆ったときにのみ絶縁強度を効果的に向上出来る
からである。
In other words, the insulation strength of the edge surface cannot be improved by increasing the inner layer insulating tape only directly above the edge surface of the rectangular conductor, but by continuously covering the two edge surfaces and the flat surface. This is because the insulation strength can only be effectively improved in some cases.

これは電気的ストレスが大きいフラット面とエツジ面と
の境界面からエツジ面までの絶縁強度を連続かつ相乗的
に改善できるからである。
This is because the insulation strength can be continuously and synergistically improved from the interface between the flat surface and the edge surface, where electrical stress is large, to the edge surface.

Next, an embodiment of the rectangular insulated wire of the present invention will be described with reference to the drawings.

The drawing is a partially cutaway perspective view showing an embodiment of this invention, in which 1 is a rectangular conductor, 2 is an insulating tape, and 3 is a tape that continuously covers the flat surface and the edge surface that characterize this invention. Inner layer insulation tape.

この内層絶縁テープは単に縦沿えして添わせただけであ

This inner layer insulating tape was simply attached vertically, and no adhesive was used at all.

従って、接着剤混入による変圧器油の電気的特性低下は
全く生じる懸念がない。
Therefore, there is no concern that the electrical characteristics of the transformer oil will deteriorate due to adhesive contamination.

なお、この考案では平角導体を用いたが、平角エナメル
