摘　　要：由于变电站故障录波装置因直流系统失电而不能正常录波,在传统的直流供电不间断电源(UPS)的基础上,设计了一种录波装置应急电源自动切换供应装置实现方案,让其在站内直流系统故障时仍然能进行一定时间的正常录波,便于事故调查,给故障录波器提供冗余供电。As the substation fault recording device cannot record properly due to the loss of DC system,a realization scheme of the automatic power supply switching device is designed for the recording device based on the traditional DC power supply uninterruptible power supply(UPS).It can still perform normal recording for a certain period of time when the DC system in the station is faulty,which is convenient for accident investigation and provides redundant power supply to the fault recorder.

关 键 词：不间断电源 录波装置 冗余供电
