タイトル（英文）

ELECTRO-MAGNETIC WAVE PROPAGATION ON THE MULTI-CONDUCTOR BUNDLES IN HIGH FREQUENCY REGIONS

概要 （図表や脚注は「報告書全文」に掲載しております）

実用多導体線路上のテレビ帯電磁波の伝搬特性の解明を目的として，（１）多導体線路における電磁波伝搬放射特性，（２）減衰定数におよぼす実用多導体線路の影響に関し，１）素導体間の相互干渉２）金属スペーサの影響３）線路導体が鋼心アルミより線である場合の影響について論理的実験的検討を行った。これらの検討結果をＵＨＶ赤城試験線に適用し測定値との比較を行い，その有用性を示した。

概要 （英文）

IN ORDER TO APPLY THE KIKUCHI-CHIBA THEORY OF THE WAVE PROPAGATION ON THE SINGLE OVERHEAD LINE TO THE MULTI-CONDUCTOR BUNDLE POWER TRANSMISSION LINES, EXPERIMENTS WERE CONDUCTED AT THE MODEL LINE AND THE UHV AKAGI TEST LINE.MAIN RESULTS ARE AS FOLLOWS. (1)THEORETICAL EXPANSION INTO THE MULTICONDUCTOR BUNDLE. 1)THE INNER IMPEDANCE RELATED TO CONDUCTOR MATERIALS AND ITS CONSTRUCTION IS IN INVERSE PROPORTION TO THE NUMBER OF SUB-CONDUCTORS. 2)THE EQUIVALENT RADIUS OF MULTI-CONDUCTOR BUNDLE SHOULD BE USED AS THE CONDUTOR RADIUS FOR THE TERMS RELATED TO GEOMETRICAL ARRANGEMENTS OF THE LINES AND GROUND. 3)THE INTERACTION OF SUB-CONDUCTORS AND THE METALIC SPACER EFFECT WERE EXPERIMENTALLY SHOWN. (2)EVALUATION OF ACSR CONDUCTOR.SUPPOSING THE NORMAL COMPORTMENT CURRENT ON ACSR CONDUCTOR, THE LARGE AMOUNT OF ATTENUATION WASCALCULATED. (3)THESE RESULTS WERE APPLIED TO THE UHV AKAGI TEST LINE. CONSIDERING THE INTERACTION OF SUB-CONDUCTORS AND THE METALIC SPACER EFFECT, THE CALCULATED ATTENUATION CONSTANT AGREED WITH MEASURED ONE.
