タイトル（英文）

V-T CHARACTERISTICS OF AIR GAPS FOR POSITIVESTEEP FRONT IMPULSE VOLTAGE

概要 （図表や脚注は「報告書全文」に掲載しております）

イメージコンバータカメラを用いて，標準インパルス電圧による気中ギャップの放電現象を詳細に観測し，リーダー速度，前駆電流などを含めたＶ－ｔ特性の予測式を提案した。ついで，急しゅん波電圧発生装置により０．３μｓまでの短時間領域のＶ－ｔ特性を実測し，その結果が前記予測式による計算結果とよく一致することを示した。

概要 （英文）

THIS PAPER DESCRIBES ON A RESEARCH THAT HAS BEEN CARRIED OUT IN ORDER TO CLARIFY THE VOLTAGE-TIME CHARACTERISTICS OF AIR GAPS FOR STEEP FRONT IMPULSES. (1)V-T CHARACTERISTICS,LEADER DEVELOPMENTS AND PREDISCHARGE CURRENTS OF AIR GAPS FOR A POSITIVE STANDARD IMPULSE WERE MEASURED WITH OSCILLOSCOPES AND AN IMAGE CONVERTER CAMERA.BASIC RELATIONS AMONG THEM WERE INVESTIGATED AND A PREDICATION METHOD OF V-T CHARATERISTICS WAS PROPOSED. (2)V-T CHARACTERISTICS OF AIR GAPS UP TO 0.3 MICRO SEC WERE MEASURED BY USING A POSITIVE STEEP FRONT IMPULSE.THE MEASURED RESULTS AGREED WITH THE V-T CHARACTERISICS CALCUATED BY THE PRDICTION METHOD MENTIONED ABOVE. (3)KIND S AREA LAW FOR V-T CHARACTERISTICS OF AIR GAPS WERE EXAMINED FROM A LOT OF DATA MEASURED BY USING STANDARDAND STEEP FROM IMPULSES.FROM THESE RESULTS,IT MAY BE CONCLUDED THAT THE LAW HOLDS WITHIN THE RANGE OF OVERVOLTAGE FACTOR FROM 1.4TO 2.5.
