| Abstract: | Experimental specimen of the short-circuits copper melted beads in the electric fire are made by simulation experiments.The microstructural morphological characteristics of the poles in short-circuits copper melted trace is qualitatively analyzed and quantitatively researched by observing their cross-sections by SEM.The result shows that based on characteristic parameters,such as diameter of pores,number density of poles and area ratio,the relationship between the formation of the copper melted beads and electric fire disaster can be judged.The composition of its surface is analyzed by EDS,and the conclusion is surface composition differences between the copper melted beads of primary and secondary short-circuits in the electric fire. |
