本考案は、内部油冷ＯＦタケ−フル接続箱に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an internal oil-cooled OF bamboo full junction box.
従来のＯＦケーブルに使用されているエポキンユニット
形油止接続箱を内部油冷ＯＦケーブルの冷却油出入用接
続箱として使用した場合の一例が第１図に示されている
。FIG. 1 shows an example of a case where an Epokin unit type oil-stop connection box used in a conventional OF cable is used as a connection box for supplying and discharging cooling oil for an internally oil-cooled OF cable.
この場合の冷却油の通路はケーブル油通路３から接続箱
内油通路６を通って出入口９に至っている。In this case, the cooling oil passage extends from the cable oil passage 3 to the inlet/outlet 9 through the oil passage 6 in the junction box.

ｓｅｃという大量の油を循環するため、第１図の構造の
場合にはエポキシベルマウス５の位置が油の流れによっ
て移動する恐れがある。For internal oil-cooled cables, the number 1 /
In the case of the structure shown in FIG. 1, the position of the epoxy bell mouth 5 may be moved due to the flow of oil because a large amount of oil of 1.5 sec is circulated.
エポキシベルマウス５が移動すると接地側の遮蔽が乱れ
、絶縁破壊を引き起す原因となる。If the epoxy bell mouth 5 moves, the shielding on the ground side will be disturbed, causing dielectric breakdown.
このような問題点を解決するために、冷却油の特別の油
通路を設ける方法もあるが、この場合には、接続箱が非
常に太きくなる欠点がある。In order to solve this problem, there is a method of providing a special oil passage for the cooling oil, but in this case, there is a disadvantage that the connection box becomes very thick.
第１図に釦いて、１は導体、２は絶縁体、４は絶縁油浸

１０は接続箱である。In Figure 1, 1 is a conductor, 2 is an insulator, 4 is an insulating oil-impregnated paper, 1 is an Epokin stop unit, 8 is a reinforced oil-impregnated paper,
10 is a connection box.
本考案は、前記した問題点を解消し、小型で安定した絶
縁性能を有する内部油冷ＯＦケーブル用接続箱を提供す
ることを目的とする。An object of the present invention is to solve the above-mentioned problems and provide a junction box for an internal oil-cooled OF cable that is compact and has stable insulation performance.
本考案の構成を一実施例を示す第２図を参照して説明す
る。The configuration of the present invention will be explained with reference to FIG. 2 showing one embodiment.
第２図にむいて、絶縁油浸紙４上に設けられたエポキシ
ベルマウス５には外側に凹部が設けられている。As shown in FIG. 2, the epoxy bell mouth 5 provided on the insulating oil-impregnated paper 4 is provided with a recess on the outside.
この凹部に対して、金属またはプラスチックの支持具１
１が円周方向２〜４ケ所に、エポキシ樹脂１３で一体モ
ールドされて固定されている。For this recess, a metal or plastic support 1
1 are integrally molded with epoxy resin 13 and fixed at two to four locations in the circumferential direction.
支持具１１の他端にはネジ加工が施されてかり、固定金
具１４に対してナツト１２で締付固定されている。The other end of the support 11 is threaded and fixed to the fixture 14 with a nut 12.
固定金具１４は接続箱１０に対して一体に固定されてい
る。The fixture 14 is integrally fixed to the connection box 10.
１５は遮蔽層である。15 is a shielding layer.
このように、支持具１１と固定金具１４等によってエポ
キシベルマウス５は確実に固定されている。In this way, the epoxy bell mouth 5 is securely fixed by the support 11, the fixing fittings 14, and the like.

１／ ｓ ｅ ｃという大量の油を循環させろことがあ
るが、本考案の接続部であれば、その油の液圧によって
もベルマウスが移動し遮蔽層が乱れろという恐れはまっ
たくない。Internally oil-cooled OF cables require a large amount of oil (several 1/sec) to be circulated in order to enhance the cooling effect, but with the connection of this invention, the bell mouth can be easily fixed even by the hydraulic pressure of the oil. There is no fear that it will move and disturb the shielding layer.
したがって、安定した絶縁性能を発揮することができろ
。Therefore, it can exhibit stable insulation performance.
また、特別の油通路を設けることがないため、接続箱全
体が小型軽量であり、極めて実用的である。Furthermore, since no special oil passage is provided, the entire junction box is small and lightweight, making it extremely practical.
