本発明はコロナ発生を防止した架空送電線の改
良に関し、特にコロナ発生を防止し得ると共に風

能な架空送電線を提供するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an overhead power transmission line that prevents the occurrence of corona, and in particular provides an overhead power transmission line that can prevent the occurrence of corona and also prevent wind noise and gearing vibration. It is.
通常、降雨時などには雨水が架空送電線表面に
球状となつて付着する。この球状の雨水は、鋭利
な突状の形状を呈するため、これからコロナ放電
が起り、コロナ雑音が発生する。このコロナ発生
は超高圧、超々高圧の送電を行うときには著し
い。 Normally, when it rains, rainwater adheres to the surface of overhead power lines in the form of a ball. Since this spherical rainwater has a sharp protruding shape, corona discharge occurs and corona noise is generated. This occurrence of corona is significant when ultra-high voltage or ultra-super high voltage power transmission is performed.
従来、このようなコロナ発生を防止した架空送

学的電気的な腐食を行つて粗面化し、これにより
外表面に親水性を具備させ、電線に付着した雨水
が鋭利な突状の形状を呈しないようになし、もつ
てコロナ発生を防止した電線が知られている。 Conventionally, overhead power transmission lines that prevent the occurrence of corona have had their outer surfaces roughened by sand blasting or chemical and electrical corrosion, making the outer surfaces hydrophilic and preventing them from adhering to the wires. Electric wires are known that prevent rainwater from forming sharp protrusions, thereby preventing the occurrence of corona.
しかしながら、この種架空送電線は電線の全外
表面を粗面化するため、非常に面倒となるばかり
か、大型の粗面化装置が必要となり不経済となる
欠点があつた。 However, this type of overhead power transmission line has the drawback that the entire outer surface of the wire is roughened, which is not only very troublesome but also requires a large-sized roughening device, which is uneconomical.
本発明はこのような欠点を改良したものであ
る。 The present invention improves these drawbacks.
これを図示した一実施例に基づき説明する。 This will be explained based on an illustrated example.
図において１は架空送電線を示し、この架空送
電線１としては鋼心アルミ撚線など公知の電線を
使用する。 In the figure, reference numeral 1 indicates an overhead power transmission line, and as this overhead power transmission line 1, a known electric wire such as a steel core aluminum stranded wire is used.
２は電線１外表面に巻付けた鋼等の金属製線状
体を示す。この金属製線状体２の外表面は、粗面
化して親水性を具備させてある。 Reference numeral 2 indicates a metal linear body made of steel or the like wound around the outer surface of the electric wire 1. The outer surface of this metal linear body 2 is roughened to have hydrophilic properties.
この粗面化の手段としては、公知の方法を種々
採用し得るが、実施例では金属製線状体２をアル
カリ性又は酸性の水溶液、例えば３％NaOH水溶
中に浸漬し、又はこの水溶液を霧状に吹付け、こ
れを自然乾燥させた。 Various known methods can be used to roughen the surface, but in the example, the metal linear body 2 is immersed in an alkaline or acidic aqueous solution, for example, a 3% NaOH aqueous solution, or this aqueous solution is misted. It was sprayed onto a sheet and allowed to air dry.
またこの金属製線状体２としては、Ｓ撚り又は
Ｚ撚り形状に成型したアーマーロツドを使用し得
る。 Further, as the metal linear body 2, an armor rod formed in an S-twist or Z-twist shape can be used.
更に、この金属製線状体２を電線１に巻付ける
手段としては、巻付けた線状体相互の間に間隔が
生じないような突き合せ状態で巻付けてもよい
が、巻付けた線状態相互の間に間隔が生じるよう
に所定の巻付けピツチで巻付けてもよい。この場
合、巻付けピツチ、線状体の線径などの巻付け形
態を選定することにより風騒音、ギヤロツピング
振動も防止し得る。 Furthermore, as a means for winding the metal wire body 2 around the electric wire 1, it is possible to wind the wire bodies 2 so that they are butted against each other so that there is no gap between the wire bodies. It may be wound with a predetermined winding pitch so that there is a gap between the states. In this case, wind noise and gearing vibration can also be prevented by selecting the winding pitch, the wire diameter of the wire body, and other winding forms.
尚、架空送電線１の外表面をも粗面化して親水
性を具備させてもよい。 Note that the outer surface of the overhead power transmission line 1 may also be roughened to provide hydrophilicity.
このように構成した本発明架空送電線は、表面
を粗面化して親水性を具備させた金属製線状体
を、架空送電線の外表面に巻付けたので、該電線
に付着した雨水は、電線を伝い線状体外表面にお
いて鋭利な突状の球状となることはなく、もつて
コロナ発生を防止し得る。 In the above-described overhead power transmission line of the present invention, a metal linear body having a roughened surface and made hydrophilic is wound around the outer surface of the overhead power transmission line, so that rainwater adhering to the wire can be removed. The electric wire does not form a sharp protruding spherical shape on the outer surface of the wire body, thereby preventing the generation of corona.
しかして本発明架空送電線によれば、粗面化す
るものは、小径の金属製線状体であるので、従来
の電線外表面を粗面化するものに比し、その取扱
いが容易であり、しかも大型の粗面化装置も必要
とすることがないので、経済性を具備する。 However, according to the overhead power transmission line of the present invention, the object to be roughened is a small-diameter metal linear body, so it is easier to handle than the conventional electric wire in which the outer surface is roughened. Moreover, since a large surface roughening device is not required, it is economical.
また、線状体の巻付形態を選定することによ
り、風騒音、ギヤロツピング振動をも防止するこ
とができる。 Furthermore, by selecting the winding form of the linear body, wind noise and gearing vibration can also be prevented.
