要約(英語): To develop an alternative test method for internal arc in SF6-insulataed power equipment, it is necessary to propose a specific procedure to replace SF6 with air and to select appropriate parameters for the tests. When carrying out the internal arc tests, it is necessary to select current, frequency, duration of current, initial filling gas pressure, and the point of arc initiation. In this paper, we conducted experiments on air and SF6 arcing in a closed container, and described the effect of the initial filling gas gauge pressure (Pini) in the container on melting loss of electrodes. Additionally, we focused on a sum of Pini and pressure rise (ΔPmax) due to arcing (Ptotal), and experimentally clarified that Ptotal of SF6 was equal to that of air by selecting the appropriate Pini of air. In the experiments, the arcs were ignited between rod electrodes by applying a current with a peak of 11kA and a duration of 40ms. The rod electrodes were made of copper, iron, and aluminum. As a result, in the case of Pini =0.5MPa(G), it was found that the amount of melting loss of any material electrode is almost equal on air and SF6. Also, in the case of air, it was clarified that the amount of melting loss of any material electrode is independent of Pini of air. Subsequently, it was experimentally clarified that Ptotal of SF6 was approximately equal to that of air by selecting Pini =0.35MPa(G)～0.4MPa(G) of air.
