=====================================


Select AC frequency converter which produces less harmonic and add inductor or capacitor filter. AC variable frequency governor can not find the use of motor failure, especially the problem of longer downtime more prominent. The reason is that the cable between the AC variable frequency governor and the motor is too long. The installation requires a cable not exceeding ZOOm and the actual cable length exceeding 30m. As a result, the signal from the AC variable frequency governor attenuates seriously, the AC variable frequency governor can not receive the feedback signal, resulting in failure. The detection signal setting value was increased and the fault was not reappeared. The problem was solved. In the field of direct shutdown or power grid fluctuation caused shutdown, AC INVERTER GOVERNOR DC bus over-voltage fault, unable to start. The reason is that the fan is a kind of equipment with large moment of inertia. When the fan is stopped, the kinetic energy stored in the fan is converted into electric energy by the motor and fed back to the AC variable frequency speed governor, causes the alternating current frequency conversion governor direct current overvoltage. The setting time of AC variable frequency speed governor is changed from 3 min to 4 min. So far, the fault has not appeared again and the problem has been solved. When the power grid fluctuates, although the motor can start itself, the process will stop. The reason is that the stop signal of AC variable frequency governor is sent to process chain stop by operating signal relay (KA2) , so when the AC variable frequency governor stops running, the stop signal is sent out immediately, leading to process chain stop. Now Stop Signal from Kaz to KTI output, Kti setting time is 45, so as long as the motor within 45 success, you can ensure that the process does not stop. After the modification, in last year's several power grid fluctuations, did not cause process shutdown, to ensure continuous production reduction. With the development of industrial automation, industrial energy-saving has become the core of industrial development, which promotes the development of frequency converter industry in China. As the core of China's industrial economic development, energy conservation and environmental protection not only point out the direction for China's industrial sustainable development, but also effectively promote the sustainable development of China's inverter industry
