Damage Pattern Analysis of Voltage Cabinet Panel due to Flame

분전반의 화염에 의한 소손패턴 분석

This paper deals with damage patterns of cabinet panel for low voltage deteriorated by flame. In order to analyze damage patterns, we used Metallurgical Microscope, x-ray system, and Fourier Transform Infrared spectroscopy. Firstly, Metallurgical microscope was used for analysis of electrical causes, such as electric short and overload Secondly, X-ray system was used for analysis of internal characteristics of circuit breakers. Lastly, Fourier Transform Infrared spectroscopy was used for analysis of damage direction by flame.

본 연구는 저압 분전함내에서 발생한 사고사례를 분석하여 사고의 메커니즘과 사고특성 등을 연구하여 사고 패턴을 제시함으로서 전기설비 사고 원인 분석 및 진단을 위한 자료를 확보하고자 하였다. 이를 위해 금속현미경, X-ray, FI-IR 등의 분석을 하였다.
