Description
本発明は、架空電線(架空地線を含む)の着氷雪を低減するための難着雪テープと、それを用いた難着雪電線に関するものである。 The present invention relates to a hard-to-snow tape for reducing icy snow on an overhead electric wire (including an overhead ground wire) and a hard-to-snow wire using the same.
架空電線の着氷雪を低減するための一つの手段として、架空電線に、氷雪が付きにくい性質のPTFE(四フッ化エチレン樹脂)テープをらせん状に巻き付けることが公知である(特許文献1参照)。 As one means for reducing the icing snow of an overhead electric wire, it is known to wrap a PTFE (tetrafluoroethylene resin) tape having a property of being hard to be attached to the overhead electric wire in a spiral shape (see Patent Document 1). .
しかしながらPTFEテープを巻いた難着雪電線は次のような問題があった。
1) 電線に巻いたPTFEテープは難着雪リングで電線に固定しているが、難着雪リングで固定したときにPTFEテープが部分的に破損することがあり、また長期間使用していると、PTFEテープが宙乗り機の走行などにより破損することがある。PTFEテープが破損すると、巻き替えを行う必要があり、信頼性の点で問題があった。
2) PTFEテープを巻くと、電線の熱放散性が低下する傾向がある。
3) PTFEテープは電気絶縁性であるため、電線表面の電位傾度が高くなると、電線とテープの隙間でギャップ放電が生じ、テープが劣化する。
4) PTFEテープは電気絶縁性であるため、僅かではあるが電線のコロナ特性が低下する。
However, the hard-to-snow electric wires wound with PTFE tape have the following problems.
1) The PTFE tape wound around the wire is fixed to the wire with a hard snow ring, but when fixed with the hard snow ring, the PTFE tape may be partially damaged and used for a long time. In some cases, the PTFE tape may be damaged due to running of the airborne machine. When the PTFE tape is damaged, it is necessary to perform rewinding, which is problematic in terms of reliability.
2) When a PTFE tape is wound, the heat dissipating property of the electric wire tends to decrease.
3) Since the PTFE tape is electrically insulating, if the potential gradient on the surface of the electric wire increases, gap discharge occurs in the gap between the electric wire and the tape, and the tape deteriorates.
4) Since the PTFE tape is electrically insulative, the corona characteristics of the wire are slightly reduced.
本発明の第一の目的は、上記1)の課題を解決した架空電線用難着雪テープと、それを用いた難着雪電線を提供することにある。
本発明の第二の目的は、上記1)〜4)の課題を解決した架空電線用難着雪テープと、それを用いた難着雪電線を提供することにある。
A first object of the present invention is to provide a snow-resistant tape for overhead electric wires that has solved the above-mentioned problem 1) and a snow-resistant wire using the same.
The second object of the present invention is to provide a snow-resistant tape for overhead electric wires that has solved the above problems 1) to 4) and a snow-resistant wire using the same.
上記第一の目的を達成する、本発明の架空電線用難着雪テープは、PTFEをガラス繊維製テープに含浸させて、架空電線に巻き付けた後に宙乗り機が走行する時に千切れなどの損傷が発生しない程度に引張り強度、引裂き強度を強化した繊維強化PTFEテープの片面に接着剤を塗布したことを特徴とするものである。 The above-mentioned first object of the present invention for the overhead wire difficult-to-cover snow tape is impregnated with PTFE in a glass fiber tape and wound around the overhead wire after the suspension machine travels. It is characterized in that an adhesive is applied to one side of a fiber reinforced PTFE tape having enhanced tensile strength and tear strength to such an extent that it does not occur.
また上記第二の目的を達成する、本発明の架空電線用難着雪テープは、カーボンを混入して導電性をもたせたPTFEをガラス繊維製テープに含浸させて、架空電線に巻き付けた後に宙乗り機が走行する時に千切れなどの損傷が発生しない程度に引張り強度、引裂き強度を強化した繊維強化導電性PTFEテープの片面に導電性接着剤を塗布したことを特徴とするものである。 In addition, the difficult-to-attach tape for an overhead wire according to the present invention, which achieves the second object, is obtained by impregnating a glass fiber tape with PTFE mixed with carbon and imparting conductivity and winding it around the overhead wire. It is characterized in that a conductive adhesive is applied to one side of a fiber reinforced conductive PTFE tape whose tensile strength and tear strength are strengthened to such an extent that damage such as tearing does not occur when the machine travels.
また本発明に係る架空電線用難着雪テープは、カーボンを混入して導電性をもたせると共に黒色にしたPTFEをガラス繊維製テープに含浸させて、架空電線に巻き付けた後に宙乗り機が走行する時に千切れなどの損傷が発生しない程度に引張り強度、引裂き強度を強化すると共に電線の熱放散性、太陽熱吸収性をよくした繊維強化導電性PTFEテープの片面に導電性接着剤を塗布したものであることが好ましい。 In addition, the hard-to-snow tape for overhead electric wires according to the present invention is made when carbon is mixed and made conductive and black PTFE is impregnated into glass fiber tape and wound on the overhead wire after being wound around the overhead wire. A conductive adhesive is applied to one side of a fiber-reinforced conductive PTFE tape that enhances the tensile strength and tear strength to the extent that damage such as tearing does not occur and improves the heat dissipation and solar heat absorption properties of the wires. It is preferable.
上記のように構成された架空電線用難着雪テープは、接着剤を内側にして、架空電線の外周にらせん状に巻き付けて使用するものである。 The overhead snow wire difficult-to-attach tape configured as described above is used by being wound spirally around the outer periphery of the overhead wire with the adhesive inside.
また本発明に係る光ファイバ複合難着雪電線は、架空電線の外周に光ファイバケーブルをらせん状に巻き付け、その外周に上記のように構成された架空電線用難着雪テープを、接着剤を内側にしてらせん状に巻き付けて、着氷雪を低減すると共に光ファイバケーブルの鳥獣による食害を防止したことを特徴とするものである。 Also, the optical fiber composite hard-to-fall snow wire according to the present invention is formed by winding an optical fiber cable in a spiral shape on the outer periphery of the overhead wire, and applying an adhesive to the outer-snow hardened tape for overhead wire as described above. It is characterized in that it is wound inwardly to reduce icing snow and to prevent damage to the optical fiber cable by birds and beasts.
以上説明したように本発明の請求項1に係る架空電線用難着雪テープは、引張り強度、引裂き強度が高いので、架空電線に巻き付けた後の宙乗り機走行時などに損傷が発生しにくく、したがって長期信頼性の高い難着雪電線を構成できる。 As described above, the difficult-to-attach tape for overhead electric wires according to claim 1 of the present invention has high tensile strength and tear strength, so that it is difficult for damage to occur when traveling on a suspension machine after being wound around the overhead wires, Therefore, it is possible to configure a snow-resisting electric wire with high long-term reliability.
また本発明の請求項2又は3に係る架空電線用難着雪テープは、請求項1と同様の効果が得られるほか、導電性を有していることから、架空電線に巻き付けた状態でギャップ放電が発生せず、ギャップ放電による劣化がない。したがって、より長期信頼性の高い難着雪電線を構成できる。さらに本発明の請求項3に係る架空電線用難着雪テープは、テープの色が黒色になるため、架空電線の熱放散性がよくなり、電流容量を大きくすることができると共に、太陽熱の吸収性がよくなり、融雪効果も得ることができる。 Moreover, since the snow-resistant tape for overhead electric wires according to claim 2 or 3 of the present invention has the same effect as that of claim 1 and has conductivity, the gap is wound around the overhead wires. No discharge occurs and there is no degradation due to gap discharge. Therefore, it is possible to configure a snow-resisting electric wire with higher long-term reliability. Furthermore, the snow-resistant tape for overhead wires according to claim 3 of the present invention has a black color, so that the heat dissipation of the overhead wires can be improved, the current capacity can be increased, and solar heat absorption can be achieved. This improves the snow melting effect.
さらに本発明の請求項4に係る光ファイバ複合難着雪電線は、上記のような効果が得られるほか、光ファイバケーブルの鳥獣による食害を防止できる。 Furthermore, the optical fiber composite hard-to-attach snow wire according to claim 4 of the present invention can obtain the effects as described above and can prevent the damage caused by birds and animals of the optical fiber cable.

この実施形態の架空電線用難着雪テープ10は、PTFEテープ16がガラス繊維製テープ14で強化された状態となっているため、引張り強度、引裂き強度が高く、架空電線22に巻き付けた後に宙乗り機が走行する時などに、千切れなどの損傷が発生することがなくなる。

In this embodiment, the difficult-to-
またこの実施形態の架空電線用難着雪テープ10は、導電性を有しているため、高電圧の架空電線22との間でギャップ放電が発生することがなく、したがってギャップ放電によるテープの劣化がなくなる。また導電性を有しているため、コロナ特性も改善される。
In addition, since the hard-to-
またカーボンが混入されていることから、テープの色が黒色になるので、電線の熱放散性がよくなって電線の電流容量が増加すると共に、太陽熱の吸収性もよくなり、融雪効果も得られる。 Also, since carbon is mixed, the color of the tape becomes black, so that the heat dissipation of the wire is improved, the current capacity of the wire is increased, the solar heat absorption is also improved, and the snow melting effect is also obtained. .
〔実施形態3〕 図5及び図6は本発明のさらに他の実施形態を示す。この実施形態は巻付け型光ファイバ複合架空電線に本発明を適用したものである。すなわち、架空電線22の外周に光ファイバケーブル30をらせん状に巻き付けて光ファイバ複合架空電線とし、その外周に図1又は図3に示した架空電線用難着雪テープ10を、接着剤18又は28を内側にしてらせん状に巻き付けたものである。

このような構成にすると、実施形態1又は2と同様な効果が得られるほか、次のような効果がある。すなわち、従来の巻付け型光ファイバ複合架空電線は、電線表面に光ファイバケーブルが露出しているため、光ファイバケーブルが鳥につつかれたり、飛翔動物(むささび、ももんが等)にかじられたりして、破損することがあったが、この実施形態のような構成にすると、光ファイバケーブル30が高強度の架空電線用難着雪テープ10によって保護されるため、上記のような鳥獣による食害を防止できる。
With such a configuration, the same effects as those of the first or second embodiment can be obtained, and the following effects can be obtained. In other words, in the conventional wrapping type optical fiber composite overhead wire, since the optical fiber cable is exposed on the surface of the wire, the optical fiber cable is caught by a bird, or it is bitten by a flying animal (musabi, peach, etc.). However, if the configuration as in this embodiment is adopted, the
なお光ファイバケーブルの鳥獣による食害を防止するためには、図5に示すように架空電線用難着雪テープ10を隙間なく巻くことが好ましいが、多少の隙間があっても鳥獣による食害を防止する効果はある。
In order to prevent the damage caused by birds and animals on the optical fiber cable, it is preferable to wrap the snow-
