地絡事故を防止するようになっている。(2) is a streamer generated by lightning striking the power transmission line (2). For example, when a streamer Ql) occurs due to a lightning strike on a steel tower, the potential of the steel tower (9) increases and the potential difference with the power transmission line (2) widens. In this case, if there is no lightning arrester (8), an overvoltage will be applied to the insulator device (3) and the arc horns (4) and (5) will flash, resulting in a ground fault. The lightning arrester (8) is installed for the purpose of suppressing overvoltage applied to the insulator (3) and preventing a ground fault caused by a flash fault between the horns. Streamer αJ due to power line lightning strike
Even in the event of an overvoltage, the unit is equipped with lightning arresters (8) to suppress overvoltage and prevent ground faults.

対向部が所定の間隙で対向するように［ｈしたものであ
る。In order to achieve this, in the power transmission line support device of the present invention, the power transmission line is supported by a steel tower via an insulator, and a first arc horn provided on the tower side of the insulator is connected to the power transmission line side. A first opposing portion and a second opposing portion are formed on the provided second arc horn, respectively, and extend toward the center of the insulator, and the opposing portions are arranged so that they face each other with a predetermined gap [h This is what I did.
第１のアークホーンは第１の対向部からＬ字状に形成さ

側とは反対方向に向けて折り曲げて円弧状に形成し、円
弧状の内径が第２の対向部に隣接しただ持部のｉα径の
３倍以上としてもよい。Further, the second opposing part of the second arc horn is bent in the direction opposite to the center side of the insulator to form an arc shape, and the inner diameter of the arc shape is the free-standing part adjacent to the second opposing part. It may be three times or more the iα diameter.
壕だ、第２のアークホーンの第２の対向部は耐候性の優

着脱可能に構成したものでもよい。The second opposing portion of the second arcing horn may be made of an insulator with excellent weather resistance, and may be configured to be detachable from a support portion adjacent to the second opposing portion.
また、第２のアークホーンは先端の第２の対向部を露出
させて、少なくとも碍子と対向した反対側を耐候性に優
れた絶縁物で覆ってもよい。Further, the second arcing horn may have the second opposing portion at the tip exposed, and at least the opposite side facing the insulator may be covered with an insulating material having excellent weather resistance.
また、第２のアークホーンの第２の対向部は碍子の中心
軸と同軸状に形成されたリング状にしても効果がある。Further, it is also effective to form the second opposing portion of the second arc horn into a ring shape coaxial with the central axis of the insulator.
さらに、第１のアークホーンは碍子の端部から地上側と
は反対側に延在した延伸部を有し、延伸部の長さが碍子
から第１の対向部までの長さの２倍以とにしても効果が
ある。Furthermore, the first arc horn has an extending portion extending from the end of the insulator to the side opposite to the ground side, and the length of the extending portion is at least twice the length from the insulator to the first opposing portion. It's effective anyway.
そして、第１のアークホーンは碍子の端部から第１の対
向部までの間から地と側とは反対側に突出した針状の複
数個の突起部を設けたものでも効果がある。It is also effective to provide the first arc horn with a plurality of needle-shaped protrusions that protrude from the end of the insulator to the first facing portion on the side opposite to the ground.
上記のように構成された送電線用支持装置へ雷撃があっ
た場合、鉄塔側の第１のアークホーンに雷撃しやずくな
っているので、第２のアークホーンの先端の電界が緩和
されてストリーマの発生が抑制される。If there is a lightning strike on the power transmission line support device configured as described above, the first arcing horn on the tower side will be hit by lightning, so the electric field at the tip of the second arcing horn will be alleviated. Generation of streamers is suppressed.
