Figure 2 power frequency automatic bypass wiring diagram
There are several issues to consider when switching systems automatically:
(1) When the frequency conversion is cut, it is necessary to judge whether the inverter is faulty or the motor itself is faulty, so as to avoid causing an expansion accident;
(2) When the frequency conversion power frequency is cut, it is necessary to solve the automatic operation problem of the damper when cutting to the power frequency operation to maintain the constant pressure and air volume of the boiler, and ensure the stable operation of the boiler. At the same time, it is necessary to consider the switching time to avoid the motor. State process
(3) When the power frequency is cut, the inverter needs to have the flying start function, so that the inverter can track the motor speed and achieve smooth switching. At the same time, the switching time also needs to consider the transition process of the motor to avoid the inverter overvoltage fault. The switch failed, causing the boiler to shut down.
