【考案の詳細な説明】
本考案は取り付けが容易であり、コスト低減が
できる支持碍子直付避雷器に関する。[Detailed Description of the Invention] The present invention relates to a lightning arrester directly attached to a supporting insulator, which is easy to install and can reduce costs.
従来の絶縁被覆配電線用の避雷装置として、例
えば、支持碍子にアークホーンを取り付け、配電
線に雷サージが進入したときアークホーンと腕金
等の間で放電させて大地に放出するようにしたも
のがある。 As a conventional lightning arrester for insulated distribution lines, for example, an arc horn is attached to a support insulator, and when a lightning surge enters the distribution line, it is discharged between the arc horn and a cross arm, etc., and released to the ground. There is something.
しかし、このアークホーン装置によれば、アー
クホーンをその放電長が適確に設定された長さに
なるように支持碍子に取り付けることが高所の作
業であることから非常に難しく、また、続流アー
クの遮断が難しいことからアークホーンが溶融し
たり、他の機材を焼損する恐れがある。 However, with this arc horn device, it is very difficult to attach the arc horn to the support insulator so that the discharge length is set to an appropriately set length because the work must be done at a high place. Since it is difficult to interrupt the flowing arc, there is a risk that the arc horn may melt or other equipment may be burnt out.
また、個々の配電線支持部に避雷器を取り付け

もに取付場所を確保することが難しいことがあ
る。 It is also conceivable to attach lightning arresters to individual distribution line supports, but this increases costs and may make it difficult to secure a mounting location.
本考案は、上記に鑑み、避雷器の取り付けが容

提供するものである。 In view of the above, the present invention is designed to facilitate the installation of lightning arresters and reduce costs.
To provide a lightning arrester directly attached to a supporting insulator in which the discharge length of the lightning arrester becomes an appropriately set length by attaching a mounting cover to which the lightning arrester is fixed to the supporting insulator.
以下本考案による支持碍子直付避雷器を詳細に

に防水処理が施される。 1 and 2 show an embodiment of the present invention, in which an insulated power distribution line 3 is fixed to a support insulator 2 fixed to a cross arm 1 by a binding wire 4. FIG. The insulation coating 3a of the insulated distribution line 3 is stripped off to expose a conductor 3b, and a lead wire 6 of a lightning arrester 5, which will be described later, is connected by a connector 7. The lightning arrester 5 has an enlarged support part 5a at the head and an arc discharge part 5c having an electric shock prevention ring 5b at the bottom. The mounting cover 8 (for example, made of hard resin) is fitted and fixed to a locking portion 8a of the mounting cover 8 (made of hard resin, for example), and is fixedly supported by the locking portion 8a. The mounting cover 8 is designed to open at the bottom, and the power distribution line 3
After fitting the supporting part 5a of the lightning arrester 5 onto the top of the support insulator 2 so as to straddle it, it is fixed by fastening the hook 8b. Note that the connector 7 portion is subjected to waterproof treatment as shown by the dotted line.

（尚、６０は固定リングである）。 3A and 3B show the lightning arrester 5, and the charging electrode 51
Zno is compressed by a disc spring 53 between the discharge electrode 52 and the discharge electrode 52, and the current collector plate 54a is inserted between them.
A lightning arrester element 54 such as the above is located. Charging electrode 51
is connected to the lead wire 6 by a crimp terminal 55,
An electric shock prevention ring 5b is fixed to the discharge electrode 52, and the arc extinguishing tube 5 is connected to the discharge electrode 52 through packings 56a and 56b.
It is housed within 7. A spacer 58 is provided on the upper part of the charging electrode 51, forming a supporting portion 5a, and is entirely molded by a mold body 59 (note that 60 is a fixing ring).

After fitting from the top of the support insulator 2 to the end of the binding wire 4 of the power distribution line 3, the hook 8b is simply tightened to support and fix it in a predetermined position. Therefore, the discharge gap formed between the discharge electrode 52 and the cross arm 1 can be set to an appropriate preset length, so that when a lightning surge enters the distribution line 3, it is ensured that the discharge continues. You can cut off the flow. According to the above embodiment, the lightning arrester 5 and the mounting cover 8 are integrated into one body by fitting together, but they can also be integrally molded in advance.
