CONTINUOUS-POWER SUPPLY SYSTEM Russian patent published in 1995 - IPC

FIELD: electric power supply. SUBSTANCE: continuous-power supply system has n a.c. power sources, each provided with coincidence unit, emf source, and linear contactor whose like-polarity output terminals are combined and connected to phase lead of load. Novelty of system is that each i-th a.c. source is provided in addition with current monitoring unit connected between emf source and linear contactor, voltage check unit, and m-input NOR gate, where m i + 1, i 1.n. Control input of linear contactor is connected to coincidence unit output, one of unit inputs is connected to NOR gate output and other input, to output of voltage check unit whose input is connected to emf source; (n 1) inputs of NOR gate in each i-th a.c. source are connected to current monitoring units of other a.c. sources and remaining inputs of mentioned NOR gate are connected to outputs of voltage check units of a.c. sources bearing numbers lower than (i-1, i-2). EFFECT: improved design. 1 dwg
