摘要
依据各种火灾导线熔痕的宏、微观特征及形成机理,对两个实际案例进行了具体的分析,从一次短路熔痕和二次短路熔痕的不同显微组织的变化特征,鉴别其熔化原因与火灾原因的关系,确认该两起火灾事故均为导线一次短路引起。
According to the macro and micro characteristics and formation mechanism of various fire wire melted mark, two actual cases were analyzed in detail, from the variation characteristics of different metallographic organization of primary short circuited melted mark and second short circuited melted mark, distinguished the relation among the melting reason and fire cause, confirmed the two fires were caused by primary short circuited.
