Power supply circuit with phase sequence protection
Source: InternetPublisher:明天见 Keywords: power supply circuit power outage motor relay Updated: 2020/03/17
If the phase sequence of the power supply is wrong, serious incidents such as motor reversal, mechanical equipment damage, and production process disruption will occur .
In order to avoid such faults, a phase sequence protection power supply circuit with phase sequence identification function can be used
, as shown in Figure 14-120. When the power supply has a positive phase sequence, the relay KA is closed and the contactor KM is closed, turning on the power supply;
when the power supply is in a negative phase sequence, KA and KM are released and the power supply is cut off.
