Typical vegetations prone 特性开展了试验研究，并提取了热释放速率、火焰温度、高 to cause line tripping were selected. The tests of combustion 度和电导率等燃烧特征量，分析了燃烧特征量对全火焰条件 characteristics, AC and DC breakdown characteristics of 下间隙击穿特性的影响机制。结果表明，不同植被类型火焰 conductor-plane gap under full flame condition were 对间隙击穿特性的影响差异较大，尤其在杉树枝火焰下，导 investigated. The combustion features, such as heat release rat
