摘要: 摘 要:近年来,架空线路故障引发的火灾频发,因涉及电力系统的供电原理,对一线火调人员提出了很高的技术要求。本文介绍了一起10 kV架空线路接地故障火灾调查过程。在火灾现场被严重破坏,前期调查起火部位认定存在歧义的情况下,调查人员通过视频分析、调查询问、现场勘验等方法,结合电力数据分析、接地故障原理和模型,综合分析认定火灾原因,还原火灾蔓延发展的过程,为10 kV架空线路接地故障火灾调查认定提供参考。

Abstract: Fires caused by overhead line faults have occurred frequently in recent years. Because it involves the power supply principle of the power system, high technical requirements are placed for fire investigator. This paper introduces the investigation process of a 10 kV overhead line ground fault fire. When the fire scene was severely damaged and the fire location was identified as ambiguity in the preliminary investigation, the investigators comprehensively analyzed the cause of the fire through video analysis, investigation and inquiry, on-site inspection and other methods, combined with power data analysis, ground fault principles and models, restore the process of fire spread and development, and provide reference for fire investigation and identification of 10 kV overhead line ground fault.

Key words: overhead line, earth fault, fire investigation, fire scene inspection
