摘　　要：本文分析了一起典型的开关机构箱加热器故障事件,通过消缺排查确定了故障发生的原因,由于上级交流电源闸刀单相电源消失,导致机构箱加热器故障,并连带发现储能电源缺相未报警的更大隐患存在。该事件提醒我们在后续巡视和技改中加强工作针对性,从而避免这类异常事件的再次发生。In this paper,a typical event of heater fault in switch mechanism box is analyzed,and the cause of the fault is determined by eliminating defects.Due to the disappearance of single-phase power supply of superior AC switch blade,the heater fault of mechanism box is caused,and it is found that there is a greater hidden danger that the energy storage power supply fails to alarm due to lack of phase.This event reminds us to strengthen the pertinence of work in the follow-up inspection and technical transformation,so as to avoid the recurrence of such abnormal events.
