Abstract
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.
