초록

전선 접속부 등에서 아산화동(Cu2O)증식 발열에 의해 화재가 발생하는 것은 화재조사 전문가들에게 널리 알려져 있지만 아산화동증식 발열에 의한 화재사례를 구체적으로 분석하여 소개하는 논문은 거의 없다. 이 논문에서는 전기적인 접속부분의 발열에 의한 화재 통계와 아산화동증식 발열 현상과 특징을 분석한 후 아산화동증식 발열에 의해 대학실험실의 전선 접속부분에서 화재가 발생한 사례에 대해 구체적으로 분석하고 있다. 이 화재사례는 발화개소의 화재패턴 조사, 전선 접속부분에 대한 육안 조사, 3차원 CT 촬영 조사, 전원인가 시험, 실체현미경 조사, SEM과 EDS 분석을 통해서 전선 접속부분에서 아산화동 증식 발열로 인해 화재가 발생한 것으로 결론을 내릴 수 있었다.

Although fires caused by heat generation due to Cu2O breeding in wire connections are well-known among fire investigators, there are few papers on the analysis and introduction of fire cases by heat generation due to Cu2O breeding. This study analyzed fire statistics caused by heat generation in electrical connections and the phenomena and features of heat generation due to Cu2O breeding. Then, a fire which occurred in the wire connection in a university lab by heat generation due to Cu2O breeding was analyzed in more detail. This fire case could reach a conclusion that heat generation due to Cu2O breeding caused a fire in the wire connection through the fire pattern investigation of fire origin, the visual investigation of wire connection, 3D CT, power-on-test, and stereoscopic microscopy, SEM and EDS analysis.
