Description

本発明は、架空送電線間に配設される多導体スペーサの主要構成部品である枠体に係り、より詳しくは、軽量で耐食性に優れた多導体スペーサの枠体に関する。   The present invention relates to a frame that is a main component of a multiconductor spacer disposed between overhead power transmission lines, and more particularly to a frame of a multiconductor spacer that is lightweight and excellent in corrosion resistance.

鉄塔などに架設された送電線により交流、若しくは直流電力を送電する場合、各々の送電線は、互いに接触しないように各送電線間にはスペーサが取付けられる。これにより、各送電線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 or DC power is transmitted through a transmission line installed on a steel tower or the like, spacers are attached between the transmission lines so that the transmission lines do not contact each other. Thereby, between each transmission line is hold | maintained at the predetermined distance according to the transmission voltage, and the contact accident by a strong wind etc. can be prevented in advance.

図3は、従来の4導体スペーサの枠体を示す構成図である。図3において、従来の枠体200は、それぞれの連結棒50が、それぞれのチャンバ60に溶接部70において溶接されて構成されている。これら、連結棒50および溶接部70は共に鋼材であるため、枠体200の全重量は、2.8kgとなっていた。   FIG. 3 is a configuration diagram showing a frame of a conventional four-conductor spacer. In FIG. 3, the conventional frame 200 is configured such that each connecting rod 50 is welded to each chamber 60 at a welding portion 70. Since the connecting rod 50 and the welded portion 70 are both steel materials, the total weight of the frame body 200 is 2.8 kg.

ところで、鉄塔間の送電線には、所定の間隔で、相当数のスペーサが取付けられている。このため、スペーサの構成部品である枠体200が重いほど、鉄塔の支持点の荷重負担が増大し、空中における架空送電線への取付け作業においても、作業負担が増大する。また、架空電線の風などによる動揺時に、枠体の重量による慣性力で生じるスペーサ自体の連結部への負担も増大する。これについては、4導体用スペーサの枠体に限らず、全ての多導体においても同様である。   Incidentally, a considerable number of spacers are attached to power transmission lines between steel towers at predetermined intervals. For this reason, the heavier the frame 200 that is a component part of the spacer, the greater the load load on the support point of the steel tower, and the work load also increases in the installation work to the overhead power transmission line in the air. In addition, when the overhead electric wire is swayed by wind or the like, the load on the connecting portion of the spacer itself generated by the inertial force due to the weight of the frame increases. This is not limited to the frame of the spacer for four conductors, and the same applies to all multiconductors.

特許文献1には、枠体の軸対象にある偶数個の位置で、対称軸のいずれか一方の片側に設けられた導体把持部が素導体を固定把持し、他方の片側に設けられたルーズ導体把持部が、素導体をルーズ用クランプ本体で把持し、このルーズ用クランプ本体を、把持した素導体の軸回りに予め設定された角度範囲で揺動自在に枠体に連結して構成する、旨の記載がある。   Patent Document 1 discloses that a conductor gripping portion provided on one side of a symmetrical axis fixedly grips an element conductor at an even number of positions on the axis of a frame body, and a looseness provided on the other side. The conductor gripping portion is configured by gripping the element conductor with the loose clamp main body, and connecting the loose clamp main body to the frame so as to be swingable within a predetermined angle range around the axis of the gripped element conductor. There is a statement to the effect.

本発明は、前述[0004]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、架空送電線間に配設される多導体スペーサの構成部品である、軽量で耐食性に優れた多導体スペーサ枠体を提供する。   The present invention has been made in order to solve the above-described problems [0004], and the object thereof is a lightweight, corrosion-resistant component that is a component of a multi-conductor spacer disposed between overhead power transmission lines.

The connecting portion has an I-shaped structure portion, the seat portion has an inner terminal penetration portion and an outer terminal penetration portion, and the inner terminal penetration portion and the outer terminal penetration portion are common terminals. has a through hole, the outer terminal through portion, have a terminal stopper for limiting the rotation of the terminal mounted through the terminal through-hole, the terminal through-hole, a concave groove formed in the outer terminal through portions provided in the bottom, the terminal stopper, Ru is formed on the side of the concave groove.

本発明によれば、架空送電線間に配設される多導体スペーサの構成部品である、軽量で耐食性に優れた多導体スペーサ枠体を提供することができる。   ADVANTAGE OF THE INVENTION According to this invention, the multiconductor spacer frame which is the lightweight and excellent corrosion resistance which is a component of the multiconductor spacer arrange | positioned between overhead power transmission lines can be provided.

本発明における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4導体スペーサの枠体を示す構造図である。8導体等、他の多導体スペーサ枠体においても、同様の基本構造を有しているため、図1においては、代表的な4導体スペーサの枠体のみを一例として説明する。図1において、本発明の多導体スペーサ枠体の一つである4導体スペーサ枠体100は、4つの連結部10と4つの座部20とが、アルミ合金一体鋳造により形成されて成り、重量は、1.1kgである。   Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a structural diagram showing a frame of a four-conductor spacer according to the present invention. Since other multi-conductor spacer frames such as eight conductors have the same basic structure, only a typical four-conductor spacer frame will be described as an example in FIG. In FIG. 1, a four-conductor spacer frame 100, which is one of the multi-conductor spacer frames of the present invention, has four connecting portions 10 and four seats 20 formed by aluminum alloy integral casting, and has a weight. Is 1.1 kg.

連結部10の断面は、アルミ合金による軽量化と共に、短絡や電線動揺による外力に対する機械的強度を維持しながら、さらなる軽量化を図ることができるI形構造部15を有している。連結部10の長さは、送電線の送電電圧により、所定の長さが決定されている。また、アルミ合金は、耐食性に優れ、靭性を有するため、枠体の極限値における破壊モードは変形モードとなり、破断等の破壊モードとなる材質より安全率を低く設定することが可能となる。また、想定外の重に対し変形で止まれば、補修により障害を安全に復帰させることが可能となる。 The cross-section of the connecting portion 10 has an I-shaped structure portion 15 that can be further reduced in weight while maintaining the mechanical strength against an external force due to a short circuit or electric wire fluctuation, as well as being reduced in weight by an aluminum alloy. The predetermined length of the connecting portion 10 is determined by the transmission voltage of the transmission line. In addition, since the aluminum alloy has excellent corrosion resistance and toughness, the fracture mode at the limit value of the frame body is a deformation mode, and the safety factor can be set lower than that of a material that has a fracture mode such as fracture. Further, When the card deformation to unexpected load heavy, it is possible to safely recover the fault by repair.

座部20は、図2に示される内側ターミナル貫通部30と外側ターミナル貫通部40とを有している。また、内側ターミナル貫通部30と外側ターミナル貫通部40とは、共通のターミナル貫通孔35を有している。外側ターミナル貫通部40は、ターミナル貫通孔35を貫通して取付けられた、送電線を把持するクランプを取付けるためのターミナル(図示せず)の回転を制限するターミナルストッパー45を有している。   The seat part 20 has the inner side terminal penetration part 30 and the outer side terminal penetration part 40 which are shown by FIG. Further, the inner terminal penetration part 30 and the outer terminal penetration part 40 have a common terminal penetration hole 35. The outer terminal penetrating portion 40 has a terminal stopper 45 that restricts rotation of a terminal (not shown) that is attached through the terminal through hole 35 and that is attached to a clamp that grips a power transmission line.

図2は、本発明による4導体スペーサの枠体の座部を示す構造図である。図2aは、図1の矢印Aから見た座部20の内側を示し、内側ターミナル貫通部30は、2段の凹部を形成している。図2bは、図1の矢印Bから見た座部20の外側を示し、外側ターミナル貫通部40は、1段の凹部にターミナルストッパーを有している。また、内側ターミナル貫通部30と外側ターミナル貫通部40とは、共通のターミナル貫通孔35を有している。   FIG. 2 is a structural view showing a seat portion of a frame body of a four-conductor spacer according to the present invention. FIG. 2a shows the inside of the seat 20 as viewed from the arrow A in FIG. 1, and the inner terminal penetration 30 forms a two-step recess. FIG. 2b shows the outside of the seat part 20 as seen from the arrow B in FIG. 1, and the outer terminal penetration part 40 has a terminal stopper in a one-step recess. Further, the inner terminal penetration part 30 and the outer terminal penetration part 40 have a common terminal penetration hole 35.

このように、ターミナルの回転規制機能を維持し、アルミ合金による軽量化と共に、I形構造により機械的強度を保ち、従来の1/2以下という軽量化を図ることが可能となる。このため、鉄塔の支持点の重負担が減少し、空中における架空送電線への取付け作業の負担も軽減される。また、架空電線の風などによる動揺時に、枠体の重量による慣性力で生じるスペーサ自体の連結部への負担も減少する。また、耐食性に優れ、靭性を有するため、破壊モードは変形モードとなり、安全率を低く設定することが可能となる。また、想定外の重による障害が変形で止まれば、補修により安全に障害を復帰させることが可能となる。これらのことから、軽量で耐食性に優れた多導体スペーサ枠体を提供することができる。 As described above, the rotation restricting function of the terminal can be maintained, the weight can be reduced by the aluminum alloy, the mechanical strength can be maintained by the I-shaped structure, and the weight can be reduced to 1/2 or less of the conventional one. Thus, loading the heavy burden of supporting points of the tower is reduced, also reduced the burden of work of mounting the overhead transmission line in air. In addition, when the overhead electric wire is swayed by wind or the like, the burden on the connecting portion of the spacer itself generated by the inertial force due to the weight of the frame body is reduced. Moreover, since it has excellent corrosion resistance and has toughness, the fracture mode becomes the deformation mode, and the safety factor can be set low. Further, When the card deformation failure due unexpected load heavy, it is possible to return safely failure by repair. From these things, the multiconductor spacer frame body which was lightweight and excellent in corrosion resistance can be provided.
