Y-△ wired centralized control circuit for reduced pressure starting water pump motor
Source: InternetPublisher:方世玉223 Keywords: Electric motor centralized control control circuit BSP Updated: 2020/01/16
The components in the dotted box are located in the control
room. The Y-△ conversion of the water pump motor
is automatically realized through the time relay KT. When the motor has overload, phase failure, or water
pump failure, the thermal relay FR will act, the motor
will stop, the indicator light H will light up, and the horn B will send out an alarm signal.
