摘要: 研究220 V交流电路中单相/双相炭化路径放电故障的形成机理,通过模拟实验研究该类故障的发生过程以及引发的火灾危险性。同时,比较分析模拟实验和送检物证的宏观形貌和金相组织,总结该类故障形成的痕迹特征,为相关痕迹鉴定方法及火灾调查提供技术支撑。

关键词: 炭化路径放电, 火灾危险性, 金相组织, 痕迹特征

Abstract: This paper mainly studies the formation mechanism of single-phase/biphasic carbonization path discharge fault in 220 V AC circuit, and studies the occurrence process of this type of fault and the fire risk by simulation experiments. At the same time, it compares and analyzes the macroscopic morphology and metallographic structure of the simulated experiment and the material evidence submitted for inspection, summarizes the characteristics of the traces formed by this type of failure, and provides technical support for related trace identification methods and fire investigations.

Key words: carbonized path arc, fire risk, metallographic structure, traces characteristics
