本考案は円筒形本体碍子の下端部に位置する袴部材に避
雷器を内蔵した筒形高圧カットアウトに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cylindrical high-voltage cutout with a lightning arrester built into a hakama member located at the lower end of a cylindrical body insulator.
従来の避雷器内蔵筒形高圧カットアウトとして、避雷器
を本体碍子の外部、例えば、碍子取付金具の一部に取付
けたものがある。As a conventional cylindrical high-voltage cutout with a built-in lightning arrester, there is one in which the lightning arrester is attached to the outside of the main insulator, for example, to a part of the insulator mounting bracket.
この形式の高圧力ットアウ斗にあっては、避雷器が碍子
の外部に設けられているため表面汚染による表面閃絡を
発生しやすく汚損特性が低下する恐れがある。In this type of high-pressure outboard, since the lightning arrester is provided outside the insulator, surface flashing is likely to occur due to surface contamination, and there is a risk that the contamination characteristics will deteriorate.
この問題の解決を図ったものに、本体碍子の側部に避雷
器収納部を一体成形により設けたものがあるが、これは
本体碍子全体を円筒状にすることができず、異形となら
ざるを得ない。One method that attempts to solve this problem is to provide a lightning arrester storage section on the side of the main insulator by integral molding, but this does not allow the entire main insulator to be made into a cylindrical shape, so it has to be irregularly shaped. I don't get it.
このため、形状が複雑になってろくろ成形ができず経済
性の点、取付作業時の取扱い性が低下する恐れがある。For this reason, the shape becomes complicated and cannot be molded on a potter's wheel, which may reduce economic efficiency and ease of handling during installation work.
上記の欠点を解消したものに、本体碍子を軸対称円筒状
にし、その内部に設けたヒユーズ筒収納′部と隔壁を介
して同心状に避雷器収納部を設けるようにした避雷器内
蔵筒形高圧カットアウトがある。A cylindrical high-voltage cut with a built-in lightning arrester that eliminates the above drawbacks is that the main body insulator is made into an axially symmetrical cylindrical shape, and the fuse tube housing section provided inside the insulator and the lightning arrester housing section are provided concentrically through the partition wall. There is an out.
この高圧カットアウトにあっては、本体碍子が軸対称円

ストの低減、形状の小型化、全体がエポキシ等でモール
ド成形された状態で避雷器が本体碍子の内部に完全内蔵
されているため、汚損特性、碍子が受ける外力に対して
大きな強度を有する等の点で優れたものである。This high-voltage cutout has an axially symmetrical cylindrical insulator, so it can be manufactured on a potter's wheel, reducing production costs, making the shape more compact, and allowing the arrester to be assembled entirely by molding with epoxy, etc. Since it is completely built inside the main insulator, it is excellent in terms of stain resistance and high strength against external forces that the insulator is subjected to.
しかしながら、ヒユーズ筒収納部と避雷器収納部とが本
体碍子内で円心状に配列されているため、本体碍子内部
の形状が複雑になり外形が大きくなる恐れがある。However, since the fuse cylinder housing portion and the lightning arrester housing portion are arranged in a circular manner within the main insulator, the internal shape of the main body insulator may become complicated and the external shape may become large.
本考案は、上記に鑑みてなされたものであり、本体碍子
の形状の簡潔化と、既存の碍子を使用して避雷器を容易
に装着できるようにするため、本体碍子の下部に位置す

器を内蔵した筒形高圧カットアウトを提供するものであ
る。The present invention was made in view of the above, and in order to simplify the shape of the main insulator and to make it possible to easily attach a lightning arrester using an existing insulator, the present invention is a hakama member located at the bottom of the main insulator. The present invention provides a cylindrical high-voltage cutout with a built-in lightning arrester in a hakama member, which accommodates the lightning arrester in the hakama member.
以下添付図面によって本考案の袴部材に避雷器を内蔵し
た筒形高圧カットアウトを詳細に説明する。Hereinafter, the cylindrical high-voltage cutout with built-in lightning arrester in the hakama member of the present invention will be explained in detail with reference to the accompanying drawings.

以上の構成において、本体碍子１は軸対称円筒状をなし
、形状が極めて簡潔であるため、ろくろ製法による製造
ができ、生産コストを低減することができる。In the above configuration, the main body insulator 1 has an axially symmetrical cylindrical shape and has an extremely simple shape, so that it can be manufactured by a potter's wheel manufacturing method and production costs can be reduced.
また、袴部材１１に避雷器１０を収納するようにしたた
め、袴部材１１の形状を変えるだけで既存の本体碍子に
避雷器１０を装着することができる。Further, since the lightning arrester 10 is housed in the hakama member 11, the lightning arrester 10 can be attached to an existing main body insulator simply by changing the shape of the hakama member 11.
さらに、避雷器１０は全体が絶縁性硬質樹脂等で成形さ

劣化が少なく、外部電極１０５も充電されないので安全
である。Since the lightning arrester 10 has a discharge gap (a space gap between the intermediate electrode 15 and the fuse lead folded part 18) on the charging side, the line voltage is not constantly applied electrically, so there is little characteristic deterioration, and the external electrode 105 is not charged. It's safe.
