Overview
Active filter (APF) multiple, multi-level PWM technology, single
capacity can reach 300A
Most of the widely used loads are non-linear loads, such as
rectifiers, inverters, UPS, elevators, air conditioners,
energy-saving lamps, copiers, household appliances, etc. These
non-linear loads will generate a large amount of harmonic currents
and inject them into the power grid, distorting the voltage
waveform, and causing serious harm to the power grid and all
back-end users. In addition, impulsive and fluctuating loads, such
as electric arc furnaces, welding equipment, etc., not only
generate a large number of high-order harmonics during operation,
but also cause power quality problems such as voltage fluctuations,
flicker, and three-phase imbalance, which seriously affect Improve
the efficiency of electrical energy use.
NAP series active filter APF can filter 2~50 harmonics dynamically
and in real time, with an effective filtering rate of 95%, fast
control of flicker and voltage fluctuations, and strong expansion
capabilities. Filters of different capacities can be mutually
expanded. Allows users to develop more flexible harmonic control
schemes.
Features
1. 200V, 400V, 600V, 750V, the capacity of a single unit can reach
3000A
2. The faulty module does not affect the operation of the normal
module, and can be replaced with power, with high reliability
3. It can dynamically filter out 2~50 harmonics in real time, and
the effective filter rate can reach 95%
4. The full response time is less than 10ms
5. Better control of flicker and voltage fluctuation
6. Unique ripple self-elimination technology, small ripple
7. High stability, design life of 20 years
Application field
1: Power system in areas with large grid harmonics, such as
factories, enterprises, etc.
2: Production enterprises that use high-power nonlinear loads and
shock loads (such as air pumps, etc.)
3: Power systems that require high power grid quality, such as
hospitals, etc.
4: Power consumption system that needs comprehensive compensation
for reactive power, harmonics and three-phase unbalance
5: The original equipment modification site or the site where it is
required to be installed in combination with the switch cabinet
