摘要
利用火灾痕迹物证综合实验台,模拟火场条件,制备电气线路火灾事故中较为常见的铜导线折断、剪断、拉断、砸断、过负荷熔断、短路熔断的痕迹样品。通过扫描电子显微镜观察和记录其断面的微观形貌特征,分析不同类型断面的成因,为各种电气线路铜导线断裂原因鉴定提供参考和依据。
The copper wire samples,which were broken,cut,snapped,crushed,overload fused and short circuit fused in fire condition were prepared by fire trace and material evidence experimental device.Through scanning electron microscope （SEM）,the microstructures of the samples fracture were observed and recorded,then the cause of different kinds of fracture were analyzed.The method of identifying the trace of the copper wire was propose to provide guides for identifying the broken reason of copper wire.
