Power supply mode easy tos produce arc grounding over-voltage and phase fault when single-phase-to-ground current is larger, is caused to power supply unit
Greatly harm.Pervious solution is to install arc-extinguishing harmonic-eliminating Coil Compensation capacitance current additional in neutral point to inhibit failure scratch start
The probability that light occurs.It will be apparent that the purpose of this method is to eliminate arc light, but due to itself all of arc-extinguishing harmonic-eliminating coil
More features, it is difficult to which being endangered caused by power supply unit capacitance current progress effective compensation, especially high frequency components can not
Overcome.Based on the above issues now using setting microcontroller integrated controller on key control panel, but intelligence is resulted in this way
Microcomputer harmonic elimination device internal structure cabling is relatively complicated, is unfavorable for itself arrangement inside Intellectual computer harmonic elimination apparatus and is repaiied with the later stage
Shield.
