以下、本発明の実施例を図面を参照して詳細に説明する
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an overhead power transmission line that combines an overhead ground wire with an optical transmission line. [Prior Art] In order to carry out optical communication using overhead power transmission lines, an overhead transmission system combines optical transmission lines by incorporating or wrapping them around an overhead ground wire! Railway lines have been put into practical use. Since the temperature of the overhead ground wire increases due to the flow of ground fault current and induced current, the combined optical transmission line must be able to withstand this temperature. For this reason, conventionally, the highest temperature of the overhead ground wire was assumed, an optical transmission line that could withstand that temperature was selected, and the same optical transmission line was used for the entire route. [Problem] Optical transmission lines are generally constructed from the required number of optical fibers and a sheath that protects them. Optical fiber coated with silicone resin, which has high heat resistance, is used as the optical fiber. However, optical transmission lines using embroidered silicone resin-coated optical fibers are expensive, and if they were used for all routes, the cost would be high. (! IB solution and its effect) The magnitude of the ground fault current flowing in the overhead ground wire is not uniform over the entire route. For example, in an overhead power transmission line connecting a substation and a load, the magnitude of the ground fault current flowing in the overhead ground wire is the highest in the section closest to the substation. It is large, and becomes smaller in the middle section or the section near the load.In addition, for overhead transmission N. lines connecting substations, it is largest in the section near the substations at both ends, and smaller in the middle section. The temperature rise of the overhead ground wire is also high in sections near the substation, and low in sections far from the substation.Therefore, the present invention has developed an overhead power transmission line that combines an overhead ground wire with an optical transmission line. The overhead ground wire in the section near the substation is combined with a heat-resistant optical transmission line using silicone resin-coated optical fiber wire, and the overhead ground wire in the section far from the substation is made of UV resin (ultraviolet curable resin). It is characterized by a combination of optical transmission lines using coated optical fibers. UV resin-coated optical fibers have lower heat resistance than silicone resin-coated optical fibers, but are cheaper. Rather than using the same optical transmission line for the entire route, the invention uses a heat-resistant optical transmission line using silicone resin-coated optical fiber for sections where the temperature rise is high, but for sections where the temperature rise is low. The cost is reduced by using an optical transmission line using an inexpensive UV resin coated optical fiber wire. [Examples] Examples of the present invention will be described in detail below with reference to the drawings. do.

送線１９が使用されている。That is, in section A near the substation 11, the temperature rise of the overhead ground wire 14 is high, so a highly heat-resistant optical transmission line as shown in Figure 2 is used. This optical transmission line 15 consists of a plurality of silicone resin-coated optical fiber wires 16 twisted together with FRP intervening material 17, etc., and a fluororesin coating such as PFA or PTFE, or a heat-resistant tape wrapping layer such as bolywood on the outer periphery. It has a heat-resistant outer covering 1B. Furthermore, in the intermediate section B away from the substation 11 and the section C near the load, optical transmission lines as shown in Figure 3 are used because the temperature rise of the overhead ground wire 14 is low. This optical transmission'4
lA19 is a UV resin coated optical fiber wire 20 made of FRP.
Twist multiple strands together with intervening l7, etc., and apply PvC to the outer periphery.
It has an outer covering of 2L made of etc. Figure 4 shows the overhead power transmission line 13 connecting substation 11P and substation 11Q. The configuration of the optical transmission line built into the overhead ground wire l4 of this overhead power transmission line 13 also differs depending on the section.

通信ルートを構戒できる利点がある。As explained above, according to the present invention, the optical transmission line combined with the overhead ground wire is not laid out in the same way over the entire route, and silicone resin optical fiber is used in sections where the temperature rise of the overhead ground wire is high. By using optical transmission lines and using inexpensive UV resin-coated bare optical fibers in sections where the temperature rise of the overhead ground wire is low, it is possible to create optical communication routes that are more economical than conventional ones. There are advantages.
