| Abstract: | The formation mechanism of copper wire short melt marks internal holes was discussed in points of atmosphere and temperature.Utilizing metallographic image analysis software,the internal holes of primary,secondary short-circuit melt mark on single,multiple strand copper wire made by simulating experiments were analyzed,and the relationships between melt marks nature and holes characteristic such as number,maximum diameter of caliper,area,roundness,roughness were decided,which can provide support for fire ca... |
