What will happen if the frequency converter governor of Roots blower is broken?

What will happen if the frequency converter governor of Roots blower is broken? The frequency converter governor is very important in the power system. Damage may cause equipment shutdown, overcurrent problems, overvoltage alarm, power quality degradation and potential safety hazards. In case of failure, it shall be immediately stopped and professionally repaired. Regular maintenance and servicing can prevent failure.

The frequency converter governor plays a vital role in the power system. Once a fault occurs, it will have a negative impact on the entire system. The following conditions may occur after the inverter governor is damaged:

Equipment shutdown: the governor damage may directly lead to equipment shutdown, especially on key production lines, which will have a serious impact on production efficiency, or even lead to production interruption.

Overcurrent problem: governor damage may cause overcurrent. This may be caused by short circuit between motor phases, short circuit to ground, or module damage. Overcurrent will not only damage the equipment itself, but also may impact the power grid and affect the stable operation of the power grid.

Overvoltage alarm: governor damage may also cause overvoltage alarm. This usually occurs during shutdown. Due to improper setting of deceleration time or damage of braking resistance, the motor is in the power generation state, which increases the DC circuit voltage in the middle of the converter and exceeds the protection value.

Power quality degradation: the governor damage may lead to the generation of high order harmonic current at the power supply side, resulting in voltage waveform distortion and affecting power quality. This will not only cause interference to other electrical equipment, but also may pose a threat to the stable operation of the entire power grid.

Potential safety hazard: governor damage may cause various faults, such as vibration and noise, which will not only affect the normal operation of equipment, but also pose a threat to the personal safety of operators.

Therefore, once the frequency converter governor is found to be faulty, it shall be immediately stopped for professional inspection and maintenance. At the same time, in order to prevent the occurrence of similar faults, the frequency converter governor should be regularly maintained to ensure that it is in good working condition.
