Dual-phase power switchover circuit schematic

Posted on Mar 28, 2007

As shown in Figure is a dual three-phase power line circuit from the vote. When electricity at the same time closing the knife switch 1HK and 2HK, 1C normally closed contacts d

isconnect the power supply SJ time relay. Power to the load. When A power outage for any reason, 1C contactor release, then IC normally closed, power relay SJ time line on the graph, time delay relay after a few seconds, so SJ delay normally open closes, 2C was electrically energized and self-locking. Since the 2C pull its normally closed one hand off-delay line drawing power, on the other hand double break 1C coil power supply circuit, so that the power to stop power supply A, B power supply to ensure normal power supply. After working for some time if the B power outage, 2C normally closed automatically switched line circle 1C A power supply replaced. Contactor shall choose according to load size; time relay available 0 ~ 60S AC relay.
