【摘要】 针对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10kV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于雷击10kV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】 The paper aims at the fire in copper workshop of powder factory in Chongqing Huahao Smelting Limited Company. The 10kV high-voltage transmission lines near the copper workshop was identified by the analysis of mechanical properties and the residual magnetic field tests. Combination the thunder weather analysis, it was concluded that the fire was caused by the lightning strike of the 10kV high-voltage transmission lines. This method provides a reference to determine whether the transmission lines fault was caused by lightning strike in the case of not installing the recorded wave and lightning counter.更多还原
