要約(日本語): In this paper, the flame patterns of residual current protective devices(RCDs) by tracking were analyzed. Pictures of tracking process were taken by High Speed Imaging System(HSIS), and fire patterns were observed by timeframe. During the tracking process of RCD, it seemed to explode just once in appearance, but in the results of HSIS analysis, a small fire broke out and disappeared repeatedly 35 times and a flash of light repeated 15 times. Finally, an explosion with a flash of light occurred and lots of particles were scattered. Electric muffle furnace was used for heat treatment of RCD cases. The surface characteristics of specimens due to heat treatment and tracking deterioration were taken by SEM(Scanning Electron Microscope). Chemical and thermal properties of these deteriorated specimens were analyzed by Fourier Transform Infrared Spectrometer(FT-IR), Differential Thermal Analyzer(DTA). The carbonization characteristics showed different chemical properties due to energy sources, and the results could be applicable to judge the accident causes.
