变电站蓄电池室可燃气体探测器告警故障分析与处置

Analysis and Disposal of Combustible Gas Detector Fault in TA Substation Battery Room

针对2020年以来,变电站辅助监控系统多次报“蓄电池室-可燃气体探测器107”告警,运维人员对现场进行检查后,发现蓄电池室可燃气体探测器动作,在开启小室内排风机后信号消失。对蓄电池工作原理、可燃气体成因以及相关消防知识进行梳理与总结,对运维人员处理相关缺陷具有一定理论与实际意义。

Since 2020, the auxiliary monitoring system of TA substation has reported "battery room combustible gas detector 107 alarm" for many times. After checking the site, the operation and maintenance workers found that the combustible gas detector in the battery room acted. The signal disappears after starting the indoor exhaust fan. Summarizing the working principle of the battery, the generation reason of combustible gas and relevant fire-fighting knowledge has certain theoretical and practical significance for the operation and maintenance workers to deal with relevant defects.
