空氣中 負極性 直流 CORONA의 發生 特性 = The Characteristics of Negative D. C. Corona Onset in Air

다국어 초록 (Multilingual Abstract)

The characteristics of the corona onset of point-to-plane gap under negative steady potentials in air were studied by using a quartz-lens camera, an electrometer, a Van de Graaff generator and an osilloscope.
The results indicated that the larger the point radius was, the more irregular corona observed.
As the gap length increases, the corona onset potential increased exponentially in the short range and increased linearly for the constant point radius and as a funtion of point radius for the fixed gap length.
The corona current decreased as the gap length increased for the constant point radius while it increased as the point radius increased with the fixed gap length.
As to the corona figure, we have also found that the axial length of streamers increased slowly for the increase of gap length.
