DEVICE FOR AUTOMATIC BACKUP OF POWER SUPPLY Russian patent published in 1994 - IPC

Abstract RU 2006134 C1

FIELD: electrical engineering. SUBSTANCE: in case of failure of any two phases of supply mains one of faulty phases is connected to remaining good phase via capacitor 19 and make contacts 7-12; other faulty phase is connected by means of reactor 20 and make contacts 13-18. In this case phases 21-23 of motor are energized and motor keeps running. EFFECT: provision for uninterrupted power supply to three-phase motor in case of failure of any two phases. 2 dwg
