【摘要】 针对2007年7月12日重庆华浩冶炼有限公司粉末厂火灾事故,用力学性能分析和剩余磁场测试相结合的方法对该厂火灾发生处的10 kV高压输电线路进行鉴定,并结合雷电天气分析,得出该火灾事故是由雷击10 kV高压输电线路造成。该方法为在没有安装录波器和闪电计数器的情况下,判断输电线路故障是否由于雷击引起提供参考。更多还原

【Abstract】 A fire case in the copper powder workshop of the Chongqing Huahao Smelting Limited Company is discussed,and the 10 kV high-voltage transmission lines near the copper powder workshop are examined by the analysis of mechanical properties and residual magnetic field tests.In combination with the thunder weather analysis,it is concluded that the fire was caused by the lightning strike on the 10 kV high-voltage transmission lines.The findings provide a reference for determining whether the transmission line fault was caused by lightning strikes in the case of not installing a wave recorder and lightning counter.更多还原
