China AC380V 690 high performance harmonic filter

Product Description

The APF products will detect the current waveform generated by non-linear load in real-time through a full digital control system, and quickly separate the harmonic part from the current waveform, and then inject the inverting current from the core inverter into the power grid to achieve the function of filtering harmonic. WBAPF can also provide leading or lagging reactive currents to improve the power factor of the grid and achieve dynamic reactive compensation.
Main Parameters:
a) Rated operating voltage: AC380V ± 20%
b) Operating frequency: 50Hz ± 5%
c) Overload capacity: 1.2 times rated current < 1 min
d) Response time: < 5ms
e) Noise: ≤ 60 dB
f) Parallel operation: support multi-machine parallel operation, and can be connected in parallel with unequal capacity
g) Communication mode: multiplex 485 communication interface (supporting GPRS wireless communication mode), one network debugging interface
h) Filtering effect: the filtering range is 2 ~ 51 times, and the harmonic filtering rate is not lower than that specified in JB/T11067-2011 when the capacity is sufficient
i) Unbalance compensation effect: the current unbalance degree after compensation is less than 3% when the capacity is sufficient.
j) MTBF (mean time between failure): ≥ 100, 000 hours

An Actual Case of the AHF/APF:

Before the APF/AHF switch on: There are harmonic and reactive losses in the grid, resulting in power quality problemsAfter the APF/AHF switch on: generating reverse harmonic current and reactive current, dynamically compensating for harmonics and reactive power, guaranteed power quality
