【考案の詳細な説明】
［産業上の利用分野］
この考案は、電力ケーブルの気中終端部、GIS
終端部、油中終端部、油止め接続部などのケーブ
ル接続部に関するものである。[Detailed explanation of the invention] [Industrial application field] This invention is applicable to the aerial termination of power cables, GIS
It relates to cable connections such as terminations, submerged terminations, and oil stop connections.
上記の接続部を組立てる場合、近年は、作業性
を向上させるために、プレフアブタイプの電界遮
蔽タイプのコーン（エポキンユニツトなどを含
む）やコンデンサコーン（以下これらを総称して
プレフアブコーンという）を使用する方式が主流
となつている。 When assembling the above connections, in recent years prefabricated electric field shielding cones (including Epokin units, etc.) and capacitor cones (hereinafter collectively referred to as prefabricated cones) have been used to improve workability. This method has become mainstream.
その場合、プレフアブコーンは、ケーブルコア
上に補強油浸紙層を設けて、その上に挿入し固定
する。 In that case, the prefabricated cone is inserted and fixed onto a reinforcing oil-impregnated paper layer on the cable core.
この考案は、ケーブル接続部のうちの、特に補
強油浸紙層とプレフアブコーンとの接触部分の構
造に関するものである。 This invention relates to the structure of the cable connection portion, particularly the contact portion between the reinforcing oil-impregnated paper layer and the prefabricated cone.
［従来の技術］ 第４図にその一例を示す。[Conventional technology] An example is shown in FIG.
ケーブルコア１０上に、広幅油浸紙を長手方向
に同径の状態で巻付けて、補強油浸紙層２０を形
成する。そしてその上に、プレフアブコーン３０
を挿入し、所定位置に固定している。 A reinforcing oil-impregnated paper layer 20 is formed by wrapping a wide oil-impregnated paper on the cable core 10 in a state of the same diameter in the longitudinal direction. And on top of that, prefab cone 30
is inserted and secured in place.
［考案が解決しようとする問題点］
上記の場合、補強油浸紙層２０の外径とプレフ
アブコーン３０の内径との差を極力小さくするよ
うにしている。しかし、その差がゼロであれば、
プレフアブコーン３０の挿入が極めて困難にな
る。[Problems to be solved by the invention] In the above case, the difference between the outer diameter of the reinforcing oil-impregnated paper layer 20 and the inner diameter of the prefabricated cone 30 is made as small as possible. However, if the difference is zero,
Insertion of the prefab cone 30 becomes extremely difficult.
そのため、補強油浸紙層２０とプレフアブコー
ン３０との間にはどうしても油隙４０ができ、そ
れが電気的の弱点になる。 Therefore, an oil gap 40 is inevitably formed between the reinforcing oil-impregnated paper layer 20 and the prefabricated cone 30, which becomes an electrical weak point.
［問題点を解決するための手段］
この考案は、第１〜３図のように、
補強油浸紙層２０に段部２２またはテーパ部２
８を設けて、それから前の部分２４の外径を後の
部分２６よりも小さくし、プレフアブコーン３０
はそのコーン立上り部３２の付近だけで補強油浸
紙層２０と接するという構造をとることによつ
て、上記の問題の解決を図つたものである。[Means for solving the problem] This invention, as shown in FIGS.
8, then the outer diameter of the front section 24 is smaller than the rear section 26, and the prefabricated cone 30
The above problem is solved by adopting a structure in which only the vicinity of the cone rising portion 32 contacts the reinforcing oil-impregnated paper layer 20.
［第１実施例］（第１図）
補強油浸紙層２０に段部２２ができるように油
浸紙を巻く。そして段部２２から前の部分２４の
外径を後の部分２６よりも小さくする。[First Example] (FIG. 1) Oil-impregnated paper is wound so that a stepped portion 22 is formed on the reinforcing oil-impregnated paper layer 20. The outer diameter of the portion 24 in front of the stepped portion 22 is made smaller than that in the portion 26 behind it.
後の部分２６の外径は、プレフアブコーン３０
の内径よりごくわずか小さ目（0.1〜0.2mm程度）
にする。 The outer diameter of the rear portion 26 is equal to that of the prefabricated cone 30.
Slightly smaller than the inner diameter (about 0.1 to 0.2 mm)
Make it.
その後、プレフアブコーン３０を挿入する。挿
入の方向は矢印５０の方向である。 Thereafter, the prefab cone 30 is inserted. The direction of insertion is in the direction of arrow 50.
プレフアブコーン３０はそのコーン立上り部３
２の内面、すなわちABの部分だけで、補強油浸
紙層２０（段部２２より後の部分２６）に接触す
る。 The prefabricated cone 30 has its cone rising portion 3
2, that is, only the portion AB contacts the reinforcing oil-impregnated paper layer 20 (the portion 26 behind the stepped portion 22).
なお、段部２２から前の部分２４とプレフアブ
コーン３０との間には、従来どおり油隙４０がで
きる。 Note that an oil gap 40 is formed between the portion 24 in front of the step portion 22 and the prefabricated cone 30 as in the conventional case.
ABの部分はプレフアブコーン３０の軸方向の
全長に比べると非常に短いため、変形等により、
補強油浸紙層２０との嵌合が多少きつくても、挿
入することが可能である。 The part AB is very short compared to the total length of the prefabricated cone 30 in the axial direction, so due to deformation etc.
Even if the fit with the reinforcing oil-impregnated paper layer 20 is somewhat tight, it can be inserted.
すなわち、密着性を、この電気ストレス的に最
もきついコーン立上り部３２の狭い部分に集中す
ることにより、密着性の改善を図ることができ
る。 That is, the adhesion can be improved by concentrating the adhesion on the narrow portion of the cone rising portion 32 where the electrical stress is most severe.
［第２実施例］（第２図）
上記の段部２２の代りに、テーパ部２８（想像
線で示した）を補強油浸紙層２０に設ける。[Second Embodiment] (FIG. 2) In place of the step portion 22 described above, a tapered portion 28 (indicated by an imaginary line) is provided in the reinforcing oil-impregnated paper layer 20.
なお、この第２図は誇張して示してあり、実際
はテーパ部２８の傾斜はごくゆるやかである。 Note that FIG. 2 is exaggerated and the inclination of the tapered portion 28 is actually very gentle.
テーパ部２８よりも後の部分２６の外径は、プ
レフアブコーン３０の内径よりも、ごくわずか
（0.1〜0.5mm程度）大きくしておく。 The outer diameter of the portion 26 behind the tapered portion 28 is made slightly larger (about 0.1 to 0.5 mm) than the inner diameter of the prefabricated cone 30.
そして、補強油浸紙層２０のテーパ部２８上に
プレフアブコーン３０を強制的に挿入する。 Then, the prefabricated cone 30 is forcibly inserted onto the tapered portion 28 of the reinforcing oil-impregnated paper layer 20.
このようにすると、補強油浸紙層２０のテーパ
部２８の一部（材質によつてはプレフアブコーン
３０の一部も）が弾性変形するとともに、補強油
浸紙層の余分な部分がずれ、プレフアブコーン３
０は、コーン立上り部３２付近の内面のABの所
要の径までの部分で、補強油浸紙層２０のテーパ
部２８と密着する。 In this way, a part of the tapered part 28 of the reinforcing oil-impregnated paper layer 20 (and also a part of the prefabricated cone 30 depending on the material) is elastically deformed, and the excess part of the reinforcing oil-impregnated paper layer is displaced, so that the prefab cone 3
0 is a portion of the inner surface near the cone rising portion 32 up to the required diameter of AB, and is in close contact with the tapered portion 28 of the reinforcing oil-impregnated paper layer 20.
［第３実施例］（第３図）
補強油浸紙層２０にテーパ部２８を設けると同
時に、プレフアブコーン３０のコーン立上り部３
２付近の内面にも、テーパ部２８と同様な傾斜を
もつたテーパ部３４を設ける。[Third Embodiment] (FIG. 3) At the same time, the tapered portion 28 is provided in the reinforcing oil-impregnated paper layer 20, and at the same time, the cone rising portion 3 of the prefabricated cone 30 is
A tapered portion 34 having the same slope as the tapered portion 28 is also provided on the inner surface near 2.
そして、プレフアブコーン３０を挿入したと
き、プレフアブコーン３０のテーパ部３４（AB
の部分）と補強油浸紙層２０のテーパ部２８とが
密着するようにする。 Then, when the prefab cone 30 is inserted, the tapered portion 34 (AB
) and the tapered portion 28 of the reinforcing oil-impregnated paper layer 20 are brought into close contact with each other.
［考案の効果］
プレフアブコーン３０と補強油浸紙層２０との
密着性がABの狭い部分に集中するので、無理な
く密着性の完全を図ることができる。[Effect of the invention] Since the adhesion between the prefabricated cone 30 and the reinforcing oil-impregnated paper layer 20 is concentrated in the narrow portion of AB, perfect adhesion can be achieved without difficulty.
またこのABの部分は特に電気的にストレスの
最も強いコーン立上り部３２であるから、この部
分の密着性が改善されることにより、電気特性が
向上する。 Further, since this part AB is the cone rising part 32 which is electrically stressed the most, the electrical characteristics are improved by improving the adhesion of this part.
