Load characteristics
.
Cigarette factory load types, including:
Production equipment: wire production line, the volume package production line, packing and other production lines on the production equipment; these production equipment are variable frequency drive equipment, serious harmonic pollution.
Power center load: including fans, pumps and so on. A large number of frequency conversion equipment, serious harmonic pollution.
Harmonic impact on automated production equipment can not be ignored, as the negative sequence harmonics to reduce the efficiency of the motor, and will cause serious waste of energy.
.
solution
.
For all low-voltage systems, configure low-voltage dynamic reactive power compensation device to absorb the main harmonic components in the system; In the serious pollution of low-voltage system, configure the parallel active power filter device; In the key load, intelligent hybrid filter compensation device to Achieve the best governance effect.
