Description
【発明の詳細な説明】 本発明は鍔付き絶縁ロッドの製造法に関する。[Detailed description of the invention] The present invention relates to a method for manufacturing a flanged insulating rod.
大容量コンダクタ−において各相間の沿面絶縁距離を確
保するために鍔を付けた絶縁ロッドが使用されている。In large-capacity conductors, insulating rods with flanges are used to ensure creepage insulation distance between each phase.
従来の絶縁ロッドは鍔を接着剤で接着して１吏用してい
た。しかしこの方法によると接着部に気泡が残り接着部
から絶縁破壊を起こし易く、高電圧機器に使用できない
欠点がある。Conventional insulating rods had a collar attached with adhesive and used as a single piece. However, this method has the drawback that air bubbles remain in the bonded portion and dielectric breakdown is likely to occur from the bonded portion, making it unsuitable for use in high voltage equipment.
この欠点を解消するために第１図の（ａ）および（ｂ）

本から欠は易く、また鍔３に使用した樹脂が成形型から
絶縁体２のＦｌ′ＬＰ絶縁層上に流出するとパリが発生
し。In order to eliminate this drawback, (a) and (b) in Figure 1
As shown in FIG. 1, a double molding method has been adopted in which the insulator 2 is molded from R and P materials, and then the collar 3 is cast and molded from epoxy resin. This method does not produce air bubbles, but on the other hand, since the materials of the insulator 2 and the tsuba 3 are different, the tsuba 3 is easily chipped from the body, and the resin used for the tsuba 3 is transferred from the mold to the fl' of the insulator 2. If it flows onto the LP insulating layer, paris will be generated.
このパリの部分を剥離させることが困難であるため製品

さらに成形金型が２組必要であると共に成形工程が２回
となるだめ高価な成形品となる欠点がある。なｔ？第１
図において１は芯金（ロッド）である。Since it is difficult to peel off this part, it is difficult to finish the product with the desired dimensions and appearance.
Furthermore, two sets of molding dies are required, and the molding process is performed twice, resulting in an expensive molded product. What? 1st
In the figure, 1 is a core metal (rod).

が最も簡単な方法であると考えるが、しかしこの方法で
は鍔と鍔の間のコンダクタ−ｅ置部位（図示せず）が巻
付けＦＲＰより機械的な価基および曲げ強度に劣り。I believe that the easiest method is to mold the tsuba and the insulator, that is, the insulating rod with the flange, from a single material such as BMC (bulk molding compound) or SMC (sheet molding compound). The conductor-e placement area (not shown) between the two is inferior in mechanical value and bending strength to that of wrapped FRP.
また絶縁体が偏肉すると耐アーク性が悪いという欠点が
ある。Also, if the thickness of the insulator is uneven, there is a drawback that arc resistance is poor.
本発明はこのような欠点に鑑み、気泡およびパリの発生
がなく９機械的な衝撃１曲げ強度が巻付けＦＲＰの強度

製造することを目的とするものである。In view of these drawbacks, the present invention aims to inexpensively manufacture a flanged insulating rod that does not generate bubbles or cracks, has a mechanical impact bending strength close to that of wrapped FRP, and has good arc resistance. The purpose is to
