Description

本発明は、架空送電線間の間隔を保つスペーサに係り、より詳しくは、スペーサのターミナル、導体把持部間で生じた導体把持部の摩耗量を容易に検知できるスペーサの導体把持部に関する。   The present invention relates to a spacer that maintains an interval between overhead power transmission lines, and more particularly to a conductor gripping portion of a spacer that can easily detect the amount of wear of a conductor gripping portion that occurs between a terminal of a spacer and a conductor gripping portion.

図２は、従来の４導体スペーサの構成図である。図２において、従来の４導体スペーサ１１０は、それぞれ４つの従来の導体把持部４０と、４つのターミナル２０と、４つのフレーム３０とから構成されている。導体把持部４０のコ型に分かれたターミナル接続部１５のそれぞれがボルト貫通孔を有し、フレーム３０に接続されたターミナル２０の端部２２が同様のボルト貫通孔を有している（図示せず）。   FIG. 2 is a configuration diagram of a conventional four-conductor spacer. In FIG. 2, the conventional four-conductor spacer 110 includes four conventional conductor gripping portions 40, four terminals 20, and four frames 30. Each of the terminal connection portions 15 divided into the U-shape of the conductor gripping portion 40 has a bolt through hole, and the end portion 22 of the terminal 20 connected to the frame 30 has a similar bolt through hole (not shown). )

導体把持部４０のコ型に分かれたターミナル接続部１５にターミナル２０の端部が挿入され、それぞれのボルト貫通孔を接続ボルト２５が貫通して導体把持部４０とターミナル２０とが接続されている。この４導体スペーサ１１０は、鉄塔に架設された４本の架空送電線５０を、導体把持部４０により把持し、４本の架空送電線５０は、フレーム３０による所定の間隔に保たれている。   The end of the terminal 20 is inserted into the terminal connection portion 15 divided into the U shape of the conductor gripping portion 40, and the connection bolt 25 passes through each bolt through hole to connect the conductor gripping portion 40 and the terminal 20. . The four-conductor spacer 110 grips the four overhead power transmission lines 50 installed on the steel tower by the conductor gripping portion 40, and the four overhead power transmission lines 50 are kept at a predetermined interval by the frame 30.

これら４本の架空送電線５０は、風によりサブスパン振動を生じるが、４導体スペーサ１１０は、この振動を防止するように動作している。この時、ボルト２５により接続された導体把持部４０とターミナル２０との間で摩擦による摩耗が発生する。この摩耗状態によってはサブスパン振動を防止できなくなるだけでなく、場合によっては、スペーサの破壊につながる。   These four overhead power transmission lines 50 generate sub-span vibration due to wind, but the four-conductor spacer 110 operates to prevent this vibration. At this time, frictional wear occurs between the conductor gripping portion 40 connected by the bolt 25 and the terminal 20. Depending on the wear state, the sub-span vibration cannot be prevented, and in some cases, the spacer is broken.

このため、導体把持部４０のターミナル接続部１５の摩耗量を測定するため、隙間ゲージ、又は他の測定治具を用いて行なわれるが、２箇所のターミナル接続部１５を測定するため手間と時間を要していた。   For this reason, in order to measure the amount of wear of the terminal connection portion 15 of the conductor gripping portion 40, a gap gauge or other measurement jig is used, but it takes time and effort to measure the two terminal connection portions 15. Needed.

特許文献１には、枠体１２、１２・・・の軸対称にある偶数個の位置で、対称軸の一方の片側に設けた導体導体把持部１４、１４で素導体１６、１６を固定把持し、他方の片側に設けたルーズ導体導体把持部２０、２０で素導体１６、１６を所定の角度範囲で揺動自在に把持する、旨の記載がある。   In Patent Document 1, the conductors 16 and 16 are fixedly held by the conductor conductor holding portions 14 and 14 provided on one side of the symmetry axis at an even number of positions of the frames 12, 12. In addition, there is a description that the loose conductor conductor holding portions 20 and 20 provided on the other side hold the element conductors 16 and 16 so as to be swingable within a predetermined angle range.

本発明によるスペーサの導体把持部の構造図。FIG. 5 is a structural diagram of a conductor gripping portion of a spacer according to the present invention. ４導体スペーサの構成図。The block diagram of 4 conductor spacers.

本発明の実施の形態について、図を用いて説明する。図１は、本発明によるスペーサの導体把持部の構造図である。図１ａにおいて、スペーサの導体把持部１０は、導体把持部１０のコ型に分かれたターミナル接続部１５のそれぞれが図２の場合と同様のボルト貫通孔を有している（図示せず）。   Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a structural diagram of a conductor holding portion of a spacer according to the present invention. In FIG. 1a, the conductor gripping portion 10 of the spacer has a bolt through hole similar to the case of FIG. 2 in each of the terminal connection portions 15 divided into the U-shape of the conductor gripping portion 10 (not shown).

そして、図２と同様に接続構成されたターミナル接続部１５の、ターミナル２０側に対向する両側のターミナル接続部１５に、複数の摩耗目盛り線１７を有している。図１ｂは、図１ａの左側のターミナル接続部１５の複数の摩耗目盛り線１７を示し、対称的に、右側のターミナル接続部１５にも複数の摩耗目盛り線１７を有する。   And the terminal connection part 15 of the terminal connection part 15 connected and comprised similarly to FIG. 2 has the some abrasion scale line 17 in the terminal connection part 15 of the both sides facing the terminal 20 side. FIG. 1 b shows a plurality of wear scale lines 17 of the left terminal connection 15 of FIG. 1 a, and symmetrically, the right terminal connection 15 also has a plurality of wear scale lines 17.

この複数の摩耗目盛り線１７は、ターミナル接続部１５の端面に沿って、図１ａの裏側に対称に延びている。また、摩耗目盛り線１７の線間隔は、ターミナル２０側に面するターミナル接続部１５の端から２ｍｍ間隔であることが望ましい。   The plurality of wear scale lines 17 extend symmetrically along the end face of the terminal connection portion 15 on the back side of FIG. Further, the line interval of the wear scale line 17 is desirably 2 mm from the end of the terminal connecting portion 15 facing the terminal 20 side.

次に、導体把持部１０のターミナル接続部１５の摩耗量の計測について説明する。従来の４導体スペーサ１１０の導体把持部４０が、本発明の導体把持部１０に置き替わる以外は、図２の場合と同様に構成されている。本発明による４導体スペーサ１００は、鉄塔に架設された４本の架空送電線５０を、本発明の導体把持部１０により把持し、４本の架空送電線５０は、フレーム３０による所定の間隔に保たれ、送電が行なわれている。   Next, measurement of the amount of wear of the terminal connection part 15 of the conductor gripping part 10 will be described.
