線路に関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention comprises forming an oil passage between an insulator provided on a conductor and an aluminum source provided outside the insulator, and filling this with insulating oil. The present invention relates to an OF cable line composed of OF cables.

部に絶縁油を充填した状態で使用している。(Prior art) Generally, an OF cable has a structure in which a hollow conductor is used as a conductor, an insulator is provided with an insulating tape wrapped thereon, and an aluminum source is applied to the outside of the insulator, and the hollow part of the conductor is insulated. It is used filled with oil.

いう問題点がある。By the way, in an OF cable having such a structure, when a composite insulating tape made by laminating and integrating a plastic film such as a polypropylene film and an insulating paper tape, or a tape made by alternately winding each independent tape, is used as the insulating tape. When performing lead work at intermediate or terminal connections, there is a problem in that plastic films such as polypropylene films melt due to the heat produced by the lead work.

補償している。In order to solve the above problems, we used a solid conductor as a conductor, and between a composite insulator made of a plastic film insulating paper tape such as polypropylene film provided on it and an aluminum source on the outside, for example, The applicant has developed an OF cable in which an oil passage is formed between the insulator and the aluminum source by wrapping a conductive band-like material such as a mild steel braided wire, and the oil passage is filled with insulating oil. Proposed. (Jitsukai Showa 5
(Refer to No. 9-173218) (Problem to be solved) An OF cable in which the hollow part of the hollow conductor described above is used as an oil passage and filled with insulating oil, or an oil passage is provided between the insulator and the aluminum source outside of the OF cable. When constructing an OF cable line using an OF cable that is formed and filled with insulating oil, conventionally, an oil stop connection is provided at the end connection of the cable and every few kilometers of the cable, and these are used as oil supply sections. Oil tanks are installed at both ends, and the insulating oil inside the cable is compensated for by using the oil passage within the conductor or between the insulator and sheath.

した従来のＯＦケーブル線路では次のような問題点が存
在する。However, recently there has been a call for disaster prevention measures for cables, and for this reason, flame-retardant insulating oils made of polydimethylsiloxane and isopropyldiphenyl, etc., are used instead of conventional mineral oils or synthetic insulating oils such as dodecylbenzene. It's starting to look like this. Such flame-retardant insulating oil is the third
As shown in the figure, compared to conventional mineral oil or synthetic insulating oil, it often has a higher viscosity at the operating temperature of the cable and a larger coefficient of volumetric expansion due to temperature rise. There are problems such as:
即ち、従来同様の油通路断面積を持ったＯＦケーブルで

輸送、布設等におけるケーブルの取扱いに多大の手数と
経費を必要とする等の問題点がある。In other words, in an OF cable with the same oil passage cross-sectional area as the conventional one, the insulating oil compensation section by the oil tank, that is, the oil supply section, is shortened, and the number of oil stop connections is increased accordingly, the length of the oil supply section is shortened, and the oil supply tank is shortened. It is necessary to increase the number of installation locations or increase the capacity and operating pressure of the oil tank. Furthermore, in order to perform compensation using a conventional oil tank, it is necessary to increase the cross-sectional area of the oil passage of the OF cable. By the way, 500'/1
In the case of a 2500 cJ OF cable, the inner diameter of the oil passage with synthetic insulating oil was 251 cm, whereas in the case of flame-retardant insulating oil, the inner diameter of the oil passage with oil flow resistance equivalent to the above oil flow resistance was 30 mm. It also becomes. As a result, the outer diameter of the cable increases and the price of the cable increases.
There are problems such as the need for a great deal of effort and expense in handling the cable during transportation, installation, etc.

をとばして給油するようにしてもよい。(Function) As mentioned above, in the OF cable line of the present invention,
OF is an oil passage formed between the cable insulator and an aluminum source provided on the outside, and filled with insulating oil.
By arranging the oil supply pipe parallel to the cable and connecting the oil supply pipe connected to the connection part, the insulating oil in the oil supply pipe and the insulating oil in the track selection path provided between the OF cable insulator and the aluminum source are communicated. The oil supply section for the oil passage of the cable is shortened to the minimum cable length between adjacent cable connections, making it possible to sufficiently compensate for the insulating oil inside the cable even if flame-retardant insulating oil with high viscosity and high expansion coefficient is used. . In this case, it is not necessary to supply oil from the oil supply pipe to all connections of the cable, and the inner diameter of the oil supply pipe, the viscosity of the insulating oil used, the coefficient of expansion, or the size of the oil pressure and the cross-sectional area of the oil passage of the cable Alternatively, multiple connections may be skipped for oil supply.
このような線路構成は本願発明におけるＯＦケーブルの

て初めて可能となるものであり、従来の導体内に油通路

両端からしか給油できず、本願発明のような構成をとる
ことが出来ない。Such a line configuration becomes possible for the first time in an OF cable that has an oil passage outside the insulator, such as the OF cable of the present invention. , - Refueling can only be performed from both ends of the refueling section, and the configuration of the present invention cannot be adopted.
かかる−給油区間の短縮化によって、前述のように油通
路断面積を大きくする必要がなく、むしろ縮小化をはか
ることができ、ケーブルサイズのコンパクト化をはかる
ことが出来る。By shortening the oil supply section, it is not necessary to increase the cross-sectional area of the oil passage as described above, but rather it can be reduced, and the cable size can be made more compact.
又本願発明のように高温にならない絶縁体の外側に油通
路を持ったＯＦケーブルを用いることによって、従来の
ように最高許容温度まで温度上昇する導体の内部に油通
路を持ったＯＦケーブルに比して、たとえ膨張係数の大
きな絶縁油であっても、絶縁油の温度変化が小さいため
、変化油量を小さく出来、給油槽の小型化及び油圧の低
減化をはかることができる。Furthermore, by using an OF cable that has an oil passage outside the insulator that does not reach high temperatures as in the present invention, it is much easier to use than the conventional OF cable that has an oil passage inside the conductor where the temperature rises to the maximum allowable temperature. Even if the insulating oil has a large expansion coefficient, the temperature change of the insulating oil is small, so the amount of oil changing can be reduced, and the oil tank can be made smaller and the oil pressure can be reduced.
さらには、ケーブルの鉛工時、油の対流冷却作用により
ポリプロピレンフィルム等のプラスチックフィルムの溶
は出しがなくなり、絶縁体にポリプロピレン等のプラス

る。Furthermore, when cables are worked with lead, the convection cooling effect of oil prevents plastic films such as polypropylene from melting, making normal lead work possible even when plastic films such as polypropylene are used as the insulator. .
