摘要：

对单芯聚氯乙烯铜导线搭铁短路故障进行模拟实验，记录火灾前和火灾中搭铁短路形成的铜导线熔痕表面组成成分随着电流增大而改变的情况，并分析其原因。通过线性回归分析讨论铜导线熔痕表面不同元素含量的影响因素。研究可为火灾事故调查工作提供科学的指导。

Abstract: Experiments were carried out to simulate the ground short circuit of single core PVC copper conductor. The changes of ground short circuit weld mark surface composition of copper wire along with the electric current increasing before and during the fire were recorded and analyzed. By linear regression analysis, the factors affecting the element content of copper wire weld mark surface was discussed. The study can provide scientific guide for fire investigation.

Key words: copper wire, ground short circuit, surface composition
