Description

本発明は、架空送電線間に配設される相間スペーサに係り、より詳しくは、架空送電線の相間距離の調節が可能な相間スペーサに関する。   The present invention relates to an interphase spacer disposed between overhead power transmission lines, and more particularly to an interphase spacer capable of adjusting a distance between overhead power transmission lines.

交流電力を鉄塔などに設置された架空送電線により送電する場合、例えば、３相交流を送電する３本の架空送電線は、互いに接触しないように各相間には相間スペーサが取付けられる。これにより、各相間は送電電圧に応じた所定の距離に保持され、強風などによる接触事故を事前に防止することができる。   When AC power is transmitted through an overhead power transmission line installed on a steel tower or the like, for example, three overhead power transmission lines that transmit three-phase AC power are provided with interphase spacers between the phases so as not to contact each other. Thereby, between each phase is hold | maintained at the predetermined distance according to the power transmission voltage, and the contact accident by a strong wind etc. can be prevented in advance.

図２は、従来の相間スペーサの構成を示す構成図である。図２において、相間スペーサ２００は、一方の架空送電線を把持するクランプ１０−１と、相間スペーサ全長を調整する金具部５０と、電線間の所定の絶縁距離を保持する碍子部２０と、他方の架空送電線を把持するクランプ１０−２とが、図に示されるように、一連に組み合わされて構成されている。   FIG. 2 is a configuration diagram showing a configuration of a conventional interphase spacer. In FIG. 2, the interphase spacer 200 includes a clamp 10-1 that holds one overhead power transmission line, a metal fitting 50 that adjusts the overall length of the interphase spacer, an insulator 20 that holds a predetermined insulation distance between the wires, and the other As shown in the figure, the clamp 10-2 that holds the overhead power transmission line is combined in series.

相間スペーサ２００の全長は、事前に鉄塔の装注寸法から取り付け箇所の相間距離が計算され、その相間距離に合う全長になるように金具部５０の長さが決定されて、相間スペーサ２００が製作されている。このように、相間スペーサ２００が製作された後に、金具部５０自身の長さを調整することは、不可能であった。   As for the total length of the interphase spacer 200, the interphase distance of the installation location is calculated in advance from the loading dimensions of the steel tower, and the length of the metal fitting 50 is determined so that the total length matches the interphase distance, and the interphase spacer 200 is manufactured. Has been. Thus, after the interphase spacer 200 was manufactured, it was impossible to adjust the length of the metal fitting 50 itself.

特許文献１には、それぞれが各架設送配電線を把持する一対の把持部と、把持部を連結支持する所定の長さを有する連結部とを備え、各把持部は、各架設送配電線を保持可能な保持孔を形成する保持部を含む一対に腕部と、各腕部の一端を回動可能に支持する支軸と、各腕部の他端を互いに係止可能に指示する係止部とを有し、保持部は、それぞれが各架設送配電線を挟持する挟持面を有する一対の挟持部材を備え、挟持面は、切りかぎ状に形成される、旨の記載がある。   Patent Document 1 includes a pair of gripping portions each gripping each erected transmission / distribution line, and a connecting portion having a predetermined length for connecting and supporting the gripping portion, and each gripping portion is connected to each erection / distribution line. A pair of arm portions including a holding portion that forms a holding hole capable of holding the arm, a support shaft that rotatably supports one end of each arm portion, and a mechanism that indicates that the other end of each arm portion can be locked together. There is a description that the holding portion includes a pair of holding members each having a holding surface for holding each erected transmission / distribution electric wire, and the holding surface is formed in a hook shape.

本発明は、このような問題を解決するためになされたものであり、その目的は、複数の架空送電線の相間距離を任意に調節可能な相間スペーサを提供する。   The present invention has been made to solve such problems, and an object thereof is to provide an interphase spacer capable of arbitrarily adjusting the interphase distance between a plurality of overhead power transmission lines.

本発明の相間スペーサは、複数の架空送電線間に設置される相間スペーサにおいて、一方の架空送電線を把持するクランプと、相間スペーサの全長を調整する長さ調整金具部と、架空送電線間の所定の絶縁距離を保持する碍子部と、他方の架空送電線を把持するクランプとを有し、長さ調整金具部は、一方の架空送電線を把持するクランプと連結される雄ねじ構造を有する雄ねじ部と、碍子部と連結される雌ねじ構造を有する雌ねじ部とから成ることを特徴とする。   The interphase spacer of the present invention is a phase spacer installed between a plurality of overhead power transmission lines, a clamp that holds one of the overhead power transmission lines, a length adjusting bracket that adjusts the overall length of the interphase spacer, and the overhead power transmission line And a clamp for holding the other overhead power transmission line, and the length adjusting bracket has a male screw structure connected to the clamp for holding one of the overhead power transmission lines. It consists of a male thread part and a female thread part which has a female thread structure connected with a lever part.

本発明によれば、ねじ構造により架空送電線間の距離を任意に調節可能とするため、相間距離の事前検討が不要となる。また鉄塔の建替えによる相間距離の変化に対応できるため、新たに相間距離を計算して相間スペーサを製作することが不要となり、且つ、架空送電線のギャロッピングなどにより発生する相間スペーサへのねじれ荷重を無くすことができる相間スペーサを提供することができる。   According to the present invention, since the distance between the overhead power transmission lines can be arbitrarily adjusted by the screw structure, a prior study of the interphase distance becomes unnecessary. In addition, since it is possible to cope with changes in interphase distance due to rebuilding of the tower, it is not necessary to newly calculate the interphase distance and manufacture interphase spacers, and torsional load on interphase spacers caused by galloping of overhead power transmission lines, etc. It is possible to provide an interphase spacer that can eliminate the problem.

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、本発明による相間スペーサの構成を示す構成図である。図１において、相間スペーサ１００は、一方の架空送電線を把持するクランプ１０−１と、相間スペーサの全長を調整する長さ調整金具部３０と、架空送電線間の所定の絶縁距離を保持する碍子部２０と、他方の架空送電線を把持するクランプ１０−２とを有している。   Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram showing a configuration of an interphase spacer according to the present invention. In FIG. 1, the interphase spacer 100 holds a predetermined insulation distance between the clamp 10-1 that holds one overhead power transmission line, the length adjustment fitting 30 that adjusts the overall length of the interphase spacer, and the overhead power transmission line. It has a lever portion 20 and a clamp 10-2 that holds the other overhead power transmission line.

また、長さ調整金具部３０は、一方の架空送電線を把持するクランプと連結される雄ねじ構造を有する雄ねじ部３４と、碍子部と連結される雌ねじ構造を有する雌ねじ部３２とから構成される。   The length adjusting metal fitting 30 is composed of a male screw part 34 having a male screw structure connected to a clamp that holds one overhead power transmission line, and a female screw part 32 having a female screw structure connected to the lever part. .

このように、相間距離の事前検討が不要となる他、鉄塔の建替え等により、架空送電線の相間距離に変動が生じた場合、長さ調整金具部３０のねじ構造により架空送電線間の距離に合わせて任意に調節が可能となる。すなわち図１において、雄ねじ部３４を矢印Ａ方向に回転させ、クランプ１０−１を矢印Ｂ方向に前進又は後退させて、架空送電線間の距離に合わせた調節が可能となる。このため、新たに相間距離を計算して相間スペーサを製作することが不要となる。また、架空送電線のギャロッピング等により発生するねじれ荷重は、当該ねじ構造により吸収されるため、ねじれ荷重による相間スペーサの破損を防止することができる。   Thus, in addition to the need for prior examination of the interphase distance, if the interphase distance of the overhead power transmission line changes due to the rebuilding of the tower, etc. It can be arbitrarily adjusted according to the distance. That is, in FIG. 1, the male screw part 34 is rotated in the direction of arrow A, and the clamp 10-1 is advanced or retracted in the direction of arrow B, so that adjustment according to the distance between the overhead power transmission lines is possible. For this reason, it is not necessary to newly calculate the interphase distance and manufacture the interphase spacer. In addition, since the torsional load generated by galloping of the overhead power transmission line is absorbed by the screw structure, damage to the interphase spacer due to the torsional load can be prevented.
