In the daily operation and maintenance of the substation,it is necessary to switch between different power sources within a fixed maintenance cycle to ensure the usability,safety and integrity of dual power sources.Although it is a dual power supply,there is still a brief power outage when switching back and forth between the two power supplies.Therefore,strictly speaking,the reliability of dual power sources is significantly enhanced compared to single power sources,but there is still a problem of intermittent power outages.we accord the actual situation on site to study the AC/DC alternating test uninterrusted power supply device in the substation,design a power supply bypass to effectively avoid indirect power outages and equipment impacts during the rotation experiment of the AC/DC system in the substation.At the same time,a complete electrical locking logic is set up to avoid power short circuit closing accidents caused by misoperation
