この発明は、雨滴付着に起因するコロナ騒音の
発生を防止した架空送電線線路に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an overhead power transmission line that prevents the generation of corona noise caused by adhesion of raindrops.
周知のように、架空送電線線路の表面に雨水が
粒（水玉）状の水滴となつて付着すると、線路表

策をもつぱら送電線導体のみを対象としてしか講
じていなかつたため、近年需用の高まりつつある
UHV線路等においては問題の根本的解決に至ら
ないものであつた。 As is well known, when rainwater adheres to the surface of an overhead power transmission line in the form of droplets, the electric field strength on the line surface becomes uneven and the potential gradient increases locally, causing corona discharge. Audible noise will result. A variety of research has been carried out to suppress this audible noise, and among these, a track surface that has been specially treated to prevent rainwater from adhering to particles is expected to have a significant noise suppression effect. However, in the past, countermeasures have only been taken for transmission line conductors, so demand has been increasing in recent years.
For UHV lines, etc., it was not possible to fundamentally solve the problem.
すなわち、UHV線路は電力需用の激増に鑑み
送電線１相当りの電流容量および送電電圧を著し

ることになるものであつた。 In other words, in view of the rapid increase in power demand, UHV lines have significantly increased current capacity and transmission voltage per transmission line, and as a result, UHV lines are large-sized lines with a larger number of divided elementary conductor groups than in the past. Despite the fact that many large accessories are used in line construction, water drop prevention measures are only applied to the main conductors of power transmission lines, such as spacers and dampers. Due to the adhesion of water droplets to the surface of the high-voltage charging part, the potential gradient becomes significantly high in that part, which causes audible noise associated with corona discharge.

上に親水性皮膜５が形成されている。 1 and 2 show an embodiment of the present invention, in which the ends of a large number of divided element conductors 2A constituting a multi-conductor power transmission line are connected to a retaining clamp 3A, a connecting fitting 3B, a yoke 3C, The tension steel tower 1 is tensile supported by the tension steel tower 1A via the tension insulator chain 6A.
The left and right power transmission lines centered on A are the detention clamps 3A.
They are electrically connected to each other by jumper conductors 2B that connect them, and the intermediate portions in the longitudinal direction of the divided element conductors 2A are connected to a suspension clamp 3D and a suspension insulator chain 6.
It is suspended and supported on the suspension tower 1B via B, and each divided element conductor 2A is connected by a spacer 3E so as to maintain a predetermined distance from each other in the span between both towers 1A and 1B, and further Damper 3G is connected to any divided elementary conductor 2A via armor rod 3F.

A, connecting fitting 3B, yoke 3C, suspension clamp 3
D, spacer 3E, armor rod 3F, damper 3G, and jumper conductor parts 3
The surfaces of all the high-voltage conductor members 3 that are at the same potential as the high-voltage electric conductor 2 such as H are formed into finely uneven and rough surfaces 4 as shown in FIG. A hydrophilic film 5 is formed on the surface.

となるものである。 In the overhead power transmission line having the above configuration, the high voltage electric conductor 2 and the high voltage conductor member 3 have an affinity for the water molecules of the hydrophilic film 5 due to the surface tension of the rainwater, which causes the surface area of the high voltage conductor 2 and the high voltage conductor member 3 to contract and bulge into a spherical shape. At the same time, the capillary phenomenon of the finely uneven rough surfaces 4 actively promotes the flow and diffusion of rainwater to the surrounding areas, so that the rainwater becomes granular water droplets on those surfaces. Adhesion is effectively prevented and the surfaces are uniformly wetted.

It is usually preferable to set it to around several microns. The hydrophilic film 5 on the uneven surface 4 can be formed by spraying boiling water, pressurized steam, steam added with ammonia or amines, etc. on the rough surface 4, or by spraying the material on which the rough surface 4 is formed. It is possible to obtain a boehmite film, an anodic oxide film, a chromate film, or the like by immersing the rough surface 4 in an atmosphere of 1, or by anodizing or chromating the rough surface 4.

The surfaces of all high-voltage conductor members 3, such as connecting fittings, yokes, suspension clamps, spacers, armor rods, dampers, and various metal parts of jumper conductor parts, have finely uneven rough surfaces 4 and rough surfaces 4 provided thereon. Since the water droplet adhesion prevention treatment consisting of a hydrophilic film 5 has been applied, rainwater does not form on the surface of not only power transmission line conductors, but also jumper conductors and various high-voltage conductor members, causing corona discharge. Therefore, it is possible to effectively prevent the occurrence of audible noise on the entire overhead power transmission line.
