Compared with the passive filter, active dynamic harmonic generator (APF) is highly controllable and fast response, not only can compensate for every harmonic, can also inhibit flicker, compensate reactive power, has the characteristic of one machine can, is based on IGBT high speed switching devices, PWM pulse width modulation technology and the theory of harmonic with the combination of high-tech products.APF unit technical indicators are as follows
The rated input voltage: 600 v + 15% ~ 15%
Rated input frequency: 50 hz
, total harmonic current rating: 600 a
Harmonic compensation number: 5, 7 times (higher harmonics)
• compensation action completion time: < 10 ms
Power consumption: 2% of the rated capacity
LCD display: operating instructions, output current, etc
Light show: plant, fault, etc.
• protection: equipment over-current, overheating, over-voltage, built-in temperature sensor, a signal is sent to the monitoring and control system.
Noise: < 65 db (room)
The cooling ways: single tank for forced air cooling
The traditional reactive power compensation device by adjusting or inductive reactive power compensation, although widely used, but some problems such as resonance, slow response time.SVG is currently the most advanced reactive compensation devices, it is no longer using the large capacity of capacitors, inductors, but by high-power power electronics of high frequency switch has no function of conversion, so that the reactive power compensation technology produced a qualitative leap.
SVG unit technical indicators are as follows:
Rated voltage: 600 v + 15% ~ 15%
• rated reactive power capacity: 2100 kvar
• rated reactive current: 2100 a
Rated input frequency: 50 hz
• compensation action completion time: < 10 ms
Power consumption: 2% of the rated capacity
LCD display: operating instructions, output current, etc
Light show: plant, fault, etc.
• protection: equipment over-current, overheating, over-voltage, built-in temperature sensor, a signal is sent to the monitoring and control system.
Noise: < 65 db (room)
The cooling ways: single tank for forced air cooling
