〔産業上の利用分野］
本発明は、油浸絶縁電カケープル（以下ＯＦケーブルと
記す）の処理方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for treating oil-immersed insulated electrical cables (hereinafter referred to as OF cables).
［従来の技術］
従来、鉛、アルミニウム等の金属シースの内部に多量の
絶縁油を収容した所謂ＯＦケーブルが、地中或いは海底
に埋設した状態で使用されている。[Prior Art] Conventionally, a so-called OF cable, in which a large amount of insulating oil is housed inside a metal sheath made of lead, aluminum, etc., has been used while being buried underground or under the sea.
［発明が解決しようとする問題点コ
しかし、ＯＦケーブルを長い年月に亘って使用すると、
金属シースが疲労や腐食奮起こし、クラックや腐食孔が
できる。このクラックや腐食孔からケーブル内の絶縁油
が外部に洩れ出し、周囲の環境汚染を引き起こす問題が
あったコまた、ＯＦケーブルの使用時に金属シースが電
気破壊し之場合や外傷を受けた場合にも同様の問題が発
生する。[Problems that the invention aims to solve] However, if the OF cable is used for a long time,
The metal sheath undergoes fatigue and corrosion, resulting in cracks and corrosion holes. There was a problem that the insulating oil inside the cable leaked out from these cracks and corrosion holes, causing contamination of the surrounding environment.Also, when the metal sheath is electrically damaged or damaged when the OF cable is used, A similar problem occurs.
かかる場合に従来は、腐食孔等を有するＯＦケーブルを
早急に撤去していたが、撤去作業は極めて大変な作業で
あった。ま次、長時間の使用を終え九〇Ｆケーブルも放
置しておくと、将来上述と同様の環境汚染を引起こす危
険がちシ、煩わしいＯＦケーブルの撤去作業をしなけれ
ばならない問題がらりた。In such cases, conventionally, OF cables having corroded holes etc. were immediately removed, but the removal work was extremely difficult. Secondly, if the 90F cable is left unattended after a long period of use, there is a risk of causing environmental pollution similar to the one mentioned above in the future, and there is the problem of having to remove the OF cable, which is a hassle.
本発明は、かかる点に鑑みてなされたものであシ、絶縁
油の漏洩を速やかに阻止して環境汚染の発生を防止し得
るＯＦケーブルの処理方法全提供するものである。The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a complete OF cable processing method that can quickly prevent leakage of insulating oil and prevent environmental pollution.
［問題点を解決するための手段］
本発明は、ＯＦチク−ルの絶縁油を収容した油通路内に
、該絶縁油を固化させる物質ｔ−注入混合し、該物質に
より前記絶縁油を固化させて前記絶８油の漏洩を防止す
ることを特徴とするＯＦケーブルの処理方法である。[Means for Solving the Problems] The present invention involves injecting and mixing a substance that solidifies the insulating oil into the oil passage containing the insulating oil of the OF chicle, and solidifying the insulating oil with the substance. This is a method for treating an OF cable, characterized in that it prevents oil from leaking.
本発明方法は、地中或は海底のような撤去作業が困難な
ところに埋設され７’ＣＯＦケーブルなどの処理に特に
有効である。The method of the present invention is particularly effective for processing 7' COF cables, etc., which are buried in places where removal work is difficult, such as underground or on the ocean floor.
本発明方法にて使用する絶縁油を固化させる物質とし′
Ｃは、ジベンジリデンソルビトール、Ｎ−ラウＯイルー
Ｌ−グルタミン酸−α、γ−ノーｎ−ブチルアミド等が
ある。A substance that solidifies the insulating oil used in the method of the present invention.
C includes dibenzylidene sorbitol, N-rauOyl-L-glutamic acid-α, γ-no-n-butyramide, and the like.
絶縁油を固化させる物質を油通路内に注入する方法とし
ては、この物質の粉末或いは液体を直接又は、イソプロ
ピルアルコール、ノルマルヘキサン等の溶媒に溶解させ
７ＩＣ溶液にして、ケーブル線路端部からポンプ等で注
入させることにより行ないケーブル全体に混合させる。The method of injecting a substance that solidifies insulating oil into the oil passage is to directly inject powder or liquid of this substance, or dissolve it in a solvent such as isopropyl alcohol or n-hexane to make a 7IC solution, and then inject it into the oil passage from the end of the cable line using a pump, etc. This is done by injecting the mixture into the entire cable.
絶縁油を固化させる物質の注入量は、ケーブル内に存在
する絶縁油の容積の５〜５０％、好ましくは、１０〜２
０％である。注入量が少なすぎる場合には絶縁油が固化
せず、多すぎ゛る場合には注入作業が困難になる。The injection amount of the substance that solidifies the insulating oil is 5 to 50%, preferably 10 to 2%, of the volume of the insulating oil present in the cable.
It is 0%. If the amount of injection is too small, the insulating oil will not solidify, and if it is too large, the injection work will be difficult.
絶縁油の固化は、上述の物質の注入後常温で放置しても
ゼリー状の状態を経て行われるが、ケーブル導体に通電
して導体を３０分〜１時間程度７０〜８０℃の温度に加
熱して固化速度を速するのが好ましい。Solidification of the insulating oil takes place through a jelly-like state even if it is left at room temperature after injecting the above-mentioned substance, but it is possible to solidify the insulating oil through a jelly-like state even if it is left at room temperature after injecting the above substance, but it can be heated to a temperature of 70 to 80 ° C for about 30 minutes to 1 hour by applying electricity to the cable conductor. It is preferable to increase the solidification rate.

を防止することができる。[Function] According to the OF cable treatment method according to the present invention, the insulating oil in the OF cable is easily solidified, so even if fatigue or corrosion occurs in the metal sheath at the installation site, it can be easily treated by applying its properties. It is possible to immediately prevent leakage of insulating oil and prevent environmental pollution.
