Roots BlowerIn the process of using the tripping situation, then what is the reason for this situation? How should it be solved? Roots blower small editor to take you to understand.
1. Too much dust accumulates on the internal board of the inverter.
2. The radiator accumulates too much dust, which reduces the heat dissipation effect of the machine itself and makes the Roots fan inverter protect the equipment and trip.
3. The internal clearance is too large, gas impurities, induced corrosion and other deposition inside the Roots fan, resulting in a reduction in the gap between the rotor and rotor, rotor and cavity and other parts of the gap, which in turn increases the load resistance, making the motor and the inverter overloaded resulting in the machine tripping protection.
4. Frequency converter selection capacity is small, frequency converter selection, should pay attention to should be larger than the rated power of the motor 20% or so, so that when the motor reaches full load, the frequency converter is still able to drive.
5, the supply voltage is too high or too low will lead to inverter overheating and protection trip, the supply voltage more than 410 volts or more, will make the inverter internal heat increase, resulting in protection trip, the supply voltage is less than 360 volts, will make the inverter work current increase, Roots fan overcurrent protection trip.
6. The rectifier template on the back of the inverter is damaged in one way, causing the other two ways to work in an overcurrent state.
7. When encountering thundery weather or the start of large equipment will cause fluctuations in the grid voltage, which will cause the inverter to lose voltage protection tripped.
