つつある。In recent years, ground wires have developed optical fiber composite power lines and optical fiber composite racks that house optical fibers inside power lines and overhead ground wires, or attach or spirally wind optical fibers to the outside of them. The formation of an optical fiber transmission system using a power transmission line network is being put into practical use.

。By the way, it is necessary to maintain the surface leakage distance from the high voltage side to the ground side of the insulator that supports the power line in an insulated state to a certain value or more, but as mentioned above, the optical fiber is When leading from the high voltage side to the ground side,
If the optical fiber is simply run parallel to the tension-resistant insulators, the leakage insulation distance on the insulator surface will essentially be the length of the portion of the optical fiber parallel to the tension-resistant insulators, and the power line support section will not be able to provide enough insulation. A problem arises in that adequate insulation cannot be ensured.

1を導いている。In the present invention, the optical fiber is connected from the high voltage side of the insulator (on the side of the retaining clamp 2 supporting the power powder 1, the lower side in Figure 2) to the ground side (on the side of the steel tower 4, on the upper side of the insulator in Figure 2). However, in this embodiment, the optical fiber 11 is guided so that it does not separate from the folds, as shown in Fig. Groove 8
a, then lead it from the side of the branch 8 to the top surface, and as shown in Fig. 3, pass it through the spiral groove Bb on the top surface, and then spirally wrap it around the outer periphery of the camp 9 and guide it to the top surface of the branch 8. In addition, the connector part 11a of the optical fiber 11 is guided to the mating insulator.
is provided at the outer periphery of camp 9, and the optical fiber 1 is provided in the same manner below.
1 along the surface of the insulator, and connect the optical fiber 1 to the ground side.
1 is leading.
そして、接地側に導かれた光ケーブル11は接続箱6に
接続さ九る。The optical cable 11 guided to the ground side is then connected to the connection box 6.

る。The optical fiber 11 is only an optical fiber, and the material is coated with a plastic resin such as polyethylene that has excellent insulation properties, and the upper surface side of the insulator is coated with silicone resin after passing the optical fiber 11 through the spiral groove 8b. etc. to make the surface smooth and prevent dust from accumulating.

イバを金肯管等に通し強度補強を図っている。In addition, between adjacent insulators, the outer surface of the optical fiber 11 including the connector part 111L should be coated with metal such as copper (the standard value of this metal is indicated by llb), or the optical fiber should be wrapped in a metal tube or the like. We aim to strengthen the through-hole strength.
なお、碍子の上面のら旋状の溝8b、および、裏面のひ
だの溝8aは、光ファイバ11の伝送損失が大きくなら
ない程度の曲率半径とする。Note that the spiral groove 8b on the top surface of the insulator and the pleat groove 8a on the back surface have a radius of curvature that does not increase the transmission loss of the optical fiber 11.

低下がなく落雷時に光ファイバ11が熱的悪影響を受け
る等の不都合も生じない。When the optical fiber 11 is arranged along the tensile insulator chain 3 as described above, the optical fiber 11 is not separated from the surface of the insulator, so the length of the optical cable 11 is the same as the length that the tensile insulator chain 3 originally has. The surface leakage insulation distance will not become shorter than the surface leakage insulation distance, and therefore, the surface leakage insulation distance of the insulator will not be shortened due to the arrangement of the optical fiber 11. Therefore, the tensile insulator chain 3 ensures sufficient insulation, there is no drop in surge voltage, and there is no problem such as the optical fiber 11 being adversely affected by heat during a lightning strike.
第5図は他の実施例を示し、この場合は、碍子の上面に
形成する溝8aがら旋状でなくほぼ直線的とさ几ている

実施例のものと同様である。Figure 5 shows yet another embodiment, in which case:
A hole 8e is made in a part near the center of the cylindrical part 8 of the insulator, and an optical fiber 11 is passed through this hole 8e.After the optical fiber 11 is passed through the hole 8e, it is filled with an insulator as described below. , the cap 9 is derived in the same manner as in the previous embodiment. Note that the optical fiber 11 is an optical fiber or is coated with a plastic resin such as polyethylene, and between adjacent insulators,
Forming a metal coating 11b on the outer surface of the optical fiber 11 including the connector portion 11a for strength reinforcement, or passing the optical fiber through a metal tube, etc. are the same as in the embodiments shown in FIGS. It is similar to

ことができるが、前者は、加工が容易である点に優れ、
後者は碍子と充填物との剥離強度が大きい点に優れる。Epoxy resin, polyethylene resin, sulfur hexafluoride (SF6), etc. are suitable for the insulator filled in the hole 8e. Epoxy resin has the advantage that it can be processed at room temperature, and polyethylene resin has particularly excellent insulation properties. The groove shape as shown in the figure can be made, but the former is superior in that it is easy to process.
The latter is superior in that it has a high peel strength between the insulator and the filler.

い。In this embodiment, the continuity of the outer surface of optical fiber 11 is
Since the hole 8e is blocked by the hole 8e and the hole 8e is sufficiently insulated, no surface leakage current flows along the entire length of the outer surface of the optical fiber 11. Therefore, the optical fiber 11 It does not reduce the surface leakage insulation distance.
着た、実施例では耐張碍子連に適用し光ものであるが、
懸垂碍子連の場合にも適用できるし、さらに碍子連でな
く碍子単体で用いる場合にも適用することができる。In the example, it is applied to a tension-resistant insulator and is light.
It can be applied to the case of a suspended insulator chain, and can also be applied to the case where an insulator alone is used instead of an insulator chain.

てもよい。When carrying out the method of the present invention, it is possible to use an insulator with an optical fiber (or insulator chain) in which an optical fiber is attached to the insulator in advance by the method described in the above embodiment. In that case, a method is adopted in which both ends of the optical fiber are connected to other optical fibers via connectors at the construction site. Alternatively, a method may be adopted in which the optical fiber is attached to the insulator at the construction site.
