镇流器火灾危险性分析及火因鉴别方法的研究

Analysis of the Fire Risk of the Ballast and the Fire Cause Determination Method

本文结合火灾案例，对如何应用金相分析技术鉴别镇流器火灾残留物进行研究。建立用金相分析技术对镇流器火灾原因进行鉴别的方法，归结出依据其熔痕的金相组织特征进行火灾原因鉴别的判据，提出对镇流器火灾的预防措施。

In the light of the fire cases, the paper discusses how to use metallographic analysis technology to determine the residue of ballast fire. It also gives the fire cause determination method of ballast fire by using the metallographic analysis technology. The fire cause determination criterion is summarized on the basis of the metallographic tissue property of the melting trace. Finally, the authors give their suggestions on the preventive measures of the ballast fire.
