Description
架空送電線の電線撤去工事における巻取り中の電線の接地器具に関する。 The present invention relates to a grounding tool for wires being wound in wire removal work for overhead transmission lines.
架空送電線の工事において、近くの架空送電線から誘導を受ける場合は、電線が移動しない時は固定接地用具を、巻き取りや繰り出しで電線が移動する時は接地金車を用いて電線を接地し、誘導電圧・電流を確実にアースして作業員の安全を確保する。これらの接地金車等は、これまでに種々開発されている。 In the construction of overhead power transmission lines, if there is induction from a nearby overhead power transmission line, use a fixed grounding tool when the wire does not move, and use a grounding wheel when the wire moves due to winding or unwinding. and ensure the safety of workers by securely grounding the induced voltage and current. Various grounding pulleys and the like have been developed so far.
これまでの接地金車等は、電線表面が劣化していない新線を対象に開発されたため、電線を傷つけない事や、電気抵抗が十分低くて作業員が接触しても安全であること等が目的となっていた。 Conventional grounding wheels, etc., have been developed for new wires that do not have deteriorated wire surfaces. was the purpose.
近年、電線の劣化に伴う張替工事が増加しているが、鋼心アルミより線が劣化すると電線表面に絶縁性被膜が生成して電線から接地金車への通電を阻害することから、これまでの接地金車等では安定して大電流を流せる必要十分な接地が付けられない事態になっていた。このため、工事現場においては、接地金車を複数個設置する等の工夫により対応していた。 In recent years, there has been an increase in replacement work due to the deterioration of electric wires. With grounding wheels, etc. up to now, the necessary and sufficient grounding that allows a large current to flow stably was not possible. For this reason, at construction sites, measures such as installing a plurality of grounding pulleys have been taken.
本発明では、絶縁性被膜を破壊してアルミ地金と接触子を接触させることにより、移動する電線と接触子との接触を確実にしつつ、安定的に通電し、かつ、電気抵抗も低減させる手段を提供する。 In the present invention, by destroying the insulating coating and bringing the contactor into contact with the aluminum base metal, the contact between the moving electric wire and the contactor is ensured, the current is stably conducted, and the electrical resistance is also reduced. provide the means.
電線表面に絶縁性の皮膜が生成された電線が連続移動している状態で、１か所以上の多点で電線表面に接触子を圧接し電線表面の絶縁性被膜を破壊して安定的に電流を取り出し導線へ排出することを特徴とする電流端子器具を提供している。導線を打ち込み式接地極、又は、鉄塔脚等の接地端子に接続すれば接地回路として成立する。 While the wire with an insulating film formed on the surface of the wire is continuously moving, the contactor is pressed against the surface of the wire at one or more points to break the insulating film on the surface of the wire and stabilize it. To provide a current terminal device characterized by extracting current and discharging it to a conductor. A grounding circuit is established by connecting a lead wire to a grounding electrode or a grounding terminal such as a tower leg.
電線表面に圧接して電線表面の絶縁被膜を破壊する接触子が複数接続されたローラチェン形状で、中央が直線で両端が半円形の概長円形の軌道上を周回する構造であって、その直線部では接触子と押付けローラの押付け力で電線を把持しながら移動できる構造とし、半円形部では直線部に至る曲率の変化で接触子が電線表面の絶縁皮膜を擦り破壊させるために電線を湾曲させる押付け力を発生させる押付けローラを備えた構造とすることを特徴とする電流端子器具を提供している。 It has a roller chain shape with multiple connected contacts that break the insulation coating on the wire surface by pressing against the wire surface, and has a structure that rotates on an approximately oval orbit with a straight center and semicircular ends. In the straight part, the wire is gripped and moved by the pressing force of the contactor and the pressing roller. To provide a current terminal device characterized by a structure including a pressing roller that generates a bending pressing force.
電流端子器具は、先行技術文献に示した接地板付きクローラ金車に電線との接触子と電流回路を備えても、電線とクローラ金車との接触圧力が弱い場合は絶縁皮膜の破壊が不十分な状態になる事が判明しているので、必要な接触圧力を発生させ、更に、擦りによる絶縁破壊で接触を万全にするものである。 In the current terminal device, even if the crawler wheel with the ground plate shown in the prior art document is equipped with a contactor for contacting the electric wire and a current circuit, the insulation film will not be destroyed if the contact pressure between the electric wire and the crawler wheel is weak. Since it has been found to be in a sufficient state, the necessary contact pressure is generated, and the contact is made perfect by dielectric breakdown due to rubbing.
また、複数の接触子が接触した状態を保たせるのは、アースすべき誘導電流が１００アンペアを超える場合があることを確認しているから考慮した結果である。 Also, the fact that a plurality of contactors are kept in contact is the result of consideration because it has been confirmed that the induced current to be grounded may exceed 100 amperes.
絶縁被膜による通電阻害がなくなり、電線が移動しても接地電流が断続的になる事もなく安定状態が保たれ、電線との接触抵抗の低減により電線への作業者の接触電位が低下して、作業者の安全性が向上する。 There is no longer any impediment to current flow due to the insulation coating, and even if the wire moves, the ground current will not become intermittent and will maintain a stable state. , worker safety is improved.
本発明によれば、原動力が不要な古電線用接地器具が可能となる。 According to the present invention, it is possible to provide an old electric wire grounding device that does not require a motive force.
