AC choke output reactor used for 5.5kw 7.5kw 11kw 15kw AC drive
Purpose
The filter reactor is used in the low-voltage filter cabinet,
connected in series with the filter capacitor, tuned to a certain
resonance frequency, and used to absorb the harmonic current of the
corresponding frequency in the power grid. There are a large number
of harmonic sources such as rectifiers, converters, and frequency
converters in the low-voltage power grid, and the high-order
harmonics generated by them will seriously endanger the safe
operation of the main transformer and other electrical equipment in
the system. After the filter reactor is connected in series with
the capacitor, it can not only effectively absorb the harmonics of
the power grid, but also improve the power factor of the system and
play a greater role in the safe operation of the system.
Material Features of Load Reactor:
1. Reducing working frequency inverter and DC speed regulator
interference to other devices, like harmonic interference, waveform
distortion.
2. Enhance the capability of frequency inverter resistance to
voltage unbalance degree. (Unbalance degree > 1.8% of rated
voltage). 3. 3. Protection frequency inverter rectifier modules and
related components damage from pinnacle capacitive current due to
low internal power resistance. (When power supply capacity is 5
times larger than frequency inverter capacity).
4. Improve the power factor of power supply, lower harmonic current
content in the inverter power supply.
5. Reduce current and voltage waveform distortion rate, improve the
quality of power supply.

Application of Load Reactor:
It is recommended to use input reactors in the following
circumstances:
1. frequency converters in parallel close connection.
2. line power supply has obvious disturbance from other devices
(interference, over voltage).
3. there is voltage imbalance between the phases of the line power
supply, exceeding 1.8% of the rated voltage.
4. a large number of converters are installed on the same line.
5. reduce cos C overload on the correction capacitor if there is a
power factor correction device in the device.
6. power supply capacity is 60KVA and above, and frequency
converter installation location is within 10M of large capacity
power supply.
7. the frequency converter is powered by a very low impedance line
(10 times higher than the inverter's rated value).
