本考案は、コロナ防止用端末金具の改良に関するもので
ある。[Detailed Description of the Invention] The present invention relates to an improvement of a terminal fitting for corona prevention.
従来のコロナ防止用端末金具は第１図に示すとおりで変
電所内の電線の終端に取付けて高電圧のコロナ放電を防
止していた。Conventional corona prevention terminal fittings, as shown in Figure 1, were attached to the ends of electric wires in substations to prevent high-voltage corona discharge.
同図においてイは端末金具１１の縦断面図で電線１２を
取付けた状態の説明図、川よ平面図である。In the same figure, A is a longitudinal sectional view of the terminal fitting 11, an explanatory view of the state in which the electric wire 12 is attached, and a horizontal plan view.
このようなコロナ防止用端末金具を取付ける必要のある
電線は１５４ｋ Ｖ以上であることから対地間の絶縁距
離を確保するために鉄構が高く、従ってその取付個所が
高所となる。Since the electric wires to which such terminal fittings for corona prevention must be attached have a voltage of 154 kV or higher, the steel structure is high to ensure an insulating distance to the ground, and therefore the installation location is high.
このような高所に１００ｔ〜２００を用もの重量の大き
な圧縮機のダイス部を吊上げる必要があり、作業性が極
めて悪く、危険性もともなう。It is necessary to lift the die part of the compressor, which weighs 100 tons to 200 tons, to such a high place, which is extremely inefficient and dangerous.
本考案は上記の欠点を解消した締付形コロナ防止キャッ
プを提供するもので、以下第２図の実施例に基づいて本
考案を説明する。The present invention provides a tightening type corona prevention cap that eliminates the above-mentioned drawbacks.The present invention will be explained below based on the embodiment shown in FIG.
第２図においてイは電線２２の端末にコロナ防止キャッ
プ２１を取付けた長さ方向の断面図、口は側面図で、２
３はノックピン、２４は水抜き穴である。In Fig. 2, A is a longitudinal cross-sectional view of the corona prevention cap 21 attached to the end of the electric wire 22, and the opening is a side view.
3 is a dowel pin, and 24 is a drain hole.
本考案の締付形コロナ防止キャップ２１は長手方向に２
分割されており、その内部は空洞２５でその内径は、電
線２２の挿入される口元２６が小さくなって、電線２２
の外径に対応している。The tightening type corona prevention cap 21 of the present invention has two
The inside is a cavity 25, and its inner diameter is such that the opening 26 into which the electric wire 22 is inserted is smaller, and the electric wire 22
corresponds to the outer diameter of
図示するように空洞２５の奥を拡げておき、電線２２の
端末を広げておくとキャップ２１の脱落防止ができる。As shown in the figure, by widening the inner part of the cavity 25 and widening the ends of the electric wires 22, the cap 21 can be prevented from falling off.
またキャップの奥の端は２分割部分がずれるとカドから
コロナが発生するので、ずれ防止のノックピン２３が取
付けられている。In addition, since corona will be generated from the edge if the two halves of the cap are displaced, a knock pin 23 is attached to the rear end of the cap to prevent displacement.
さらにキャップ２１の口元２６には電線２２を把持する
ボルト２７を設けである。Furthermore, a bolt 27 for gripping the electric wire 22 is provided at the opening 26 of the cap 21.
本考案の締付形コロナ防止キャップの利点は、（１）ボ
ルト締付構造であるから高所に重量の大きな圧縮ダイス
部を吊上げる必要がないので作業性が良い。The advantages of the tightening type corona prevention cap of the present invention are: (1) Since it has a bolt tightening structure, it is not necessary to lift a heavy compression die part to a high place, so it is easy to work.
（２）ノックピンを取付けて２つ割れ部のズレを防いで
いるので、コロナが発生しにくい。(2) A dowel pin is installed to prevent the two cracks from shifting, making it difficult for corona to occur.
（３）キャップ内部の奥を口元より拡げているので、電
線端末部をバラバラにして拡げ脱落防止ができる。(3) Since the inner part of the cap is wider than the mouth, it is possible to break apart the wire terminals and spread them out to prevent them from falling off.
等である。etc.
以上のとおりであるので、本考案の締付形コロナ防止キ
ャップは、硬アルミ撚線、耐熱アルミ撚線、ＡＣ３Ｒ等
の変電所内の超高圧級撚線の端末キャップとしての実用
的効果は大きい。As described above, the tightening type corona prevention cap of the present invention has a great practical effect as a terminal cap for ultra-high voltage class stranded wires in substations such as hard aluminum stranded wires, heat-resistant aluminum stranded wires, and AC3R.
