従来より回転電機の単層同心巻三相固定子巻線の相間絶縁は各相間に相間絶 縁紙を挿入し、さらにコイルエンド部を縛り糸にて固定している。以下図面を参 照しながら説明する。図４は、従来より一般的に使用されている相間絶縁物たる 相間絶縁紙の形状で平滑な薄片であり、図５の如く相間絶縁紙４はスロット絶縁 紙６とつき合せの状態に挿入される。さらに、図６の如く相間絶縁紙４とコイル エンド３とを縛り糸にて緊縛することにより、相間絶縁紙４が矢印方向に引き上 げられ、スロット絶縁紙６端に近いコイル相間の絶縁が不十分な状態となり、コ イルエンド３の各相間絶縁が形成されず異相間コイルの接触が発生する。 Conventionally, the phase-to-phase insulation of the single-layer concentric winding three-phase stator winding of rotating electric machines has been A border paper is inserted and the coil end is secured with a tying thread. See the drawing below. I will explain it while referring to it. Figure 4 shows interphase insulators commonly used in the past. It is a smooth thin piece in the shape of interphase insulating paper, and as shown in Figure 5, the interphase insulating paper 4 is a slot insulator. The paper 6 is inserted in abutting state. Furthermore, as shown in FIG. 6, interphase insulating paper 4 and coil By tying the end 3 with a tying thread, the interphase insulating paper 4 is pulled up in the direction of the arrow. As a result, the insulation between the coil phases near the 6 ends of the slot insulation paper is insufficient, and the coil Insulation between each phase of the coil end 3 is not formed, and contact between coils of different phases occurs.

前記の状態で回転電機を運転するならば、異相間接触により接触部分の絶縁 が除々に熱劣化し、更に振動により部分的な絶縁劣化が生じてコイルエンド部で 異相間絶縁破壊となり、コイル焼損事故が発生する原因となる問題点があった。 この考案は、上記のような問題点を解消するためになされたもので、コイル異 相間に使用する相間絶縁が、コイルエンド縛り糸によって相間絶縁不良を起すお それのない相間絶縁物を提供することを目的とする。 ［考案の構成］ If a rotating electric machine is operated under the above conditions, the contact parts will be insulated due to contact between different phases. gradually deteriorates due to heat, and furthermore, vibration causes partial insulation deterioration, causing damage at the coil end. There was a problem that caused dielectric breakdown between different phases and caused a coil burnout accident. This idea was made to solve the problems mentioned above, and was designed to prevent coil differences. The interphase insulation used between the phases may cause interphase insulation failure due to the coil end tying thread. The purpose is to provide interphase insulation without it. [Structure of the idea]

この従来の問題点を解決するため、本考案の固定子巻線の相間絶縁紙におい て、コイルエンド部を緊縛する際に生じる相間絶縁紙のズレを防止し、完全にコ イル相間に固着巻装されるように凹形状の相間絶縁物に縛り糸用の溝と横移動防 止用のアコーディオン型折り目を構成している。 In order to solve this conventional problem, the insulating paper between the phases of the stator winding of the present invention was This prevents the interphase insulating paper from shifting when the coil ends are tied together, and ensures complete control. A concave-shaped interphase insulator has grooves for the tying thread and lateral movement prevention so that it can be tightly wound between the layers. It has an accordion-shaped fold for closure.

相間絶縁紙の内側に縛り糸用溝を配設し、さらに大コイルと小コイルとの間 にアコーディオン型の折り目をスカートの如く形成され、このことにより相間絶 縁紙が縛り糸によって浮き上りが防止でき、さらに横へのすべりも防止すること ができる。従って結果的に絶縁性の高い信頼できる高品質回転電機を提供するこ とが可能となる。 A groove for tying thread is provided inside the interphase insulating paper, and a groove is provided between the large coil and small coil. The accordion-shaped folds are formed like a skirt, and this creates a sense of separation. The binding thread prevents the border paper from lifting up, and also prevents it from sliding sideways. I can do it. Therefore, it is possible to provide reliable, high-quality rotating electric machines with high insulation properties. becomes possible.

以下、本考案の一実施例について図面を参照しながら説明する。図１は本考 案の一実施例による相間絶縁紙４である。なお、従来構成と同じ部分については 同じ符号を付して詳細説明は省略する。図に於いて、スロット溝ピッチに合せて 縛り糸溝ｗ 1，ｗ 2を溝幅Ｗ 1乃至Ｗ 3のピッチで配列し、挿入された相間絶縁 紙４は縛り糸５により緊縛されても、縛り溝により浮き上りが防止できる。An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an interphase insulating paper 4 according to an embodiment of the present invention. Note that the same parts as in the conventional configuration are designated by the same reference numerals, and detailed description thereof will be omitted. In the figure, even if the tying thread grooves w 1 and w 2 are arranged at a pitch of groove widths W 1 to W 3 in accordance with the slot groove pitch, and the interphase insulating paper 4 inserted is bound by the tying thread 5, The binding grooves prevent lifting.
【０００７】 さらに、凹形状の内側突出部に突出部の突出方向に平行してアコーディオン型 の折り目４ａ（ジャバラ折り目）を形成させ、大コイルと小コイルとの間に配置 することにより、この縦方向の折り目４ａが突起となって相間絶縁紙４の横移動 を防止してコイルエンド３の成形や、縛り糸５の引っぱりによりズレが防止でき る。[0007] Furthermore, an accordion-shaped Form a fold 4a (bellows fold) and place it between the large coil and small coil. By doing so, this vertical fold 4a becomes a protrusion and the interphase insulating paper 4 moves laterally. By molding the coil end 3 and pulling the binding thread 5, misalignment can be prevented. Ru.
【０００８】 図２は本考案の相間絶縁紙４が挿入された状態であり、コイルエンド３部を縛 り糸５によって緊縛された図３でも上記状態が不変となる。さらに相間絶縁紙４ のコイルエンド３部の外側には肩面４ｃをコイルエンド３部の内側には溝面４ｄ を配設したことにより、コイルエンド部にそって相間絶縁紙４の切断も不用とな る。[0008] Figure 2 shows a state in which the interphase insulating paper 4 of the present invention is inserted, and the coil end 3 is tied. The above-mentioned state remains unchanged even in the case shown in FIG. Furthermore, interphase insulating paper 4 There is a shoulder surface 4c on the outside of the coil end 3 part, and a groove surface 4d on the inside of the coil end 3 part. By arranging this, there is no need to cut the interphase insulating paper 4 along the coil end. Ru.
