General
GDAPF active power filter cabinet, also known as active power filter, is a new type of power electronic device used for dynamic suppression of harmonics and compensation of reactive power. It can compensate for harmonics and reactive power that vary in size and frequency.
Mainly used in the communication industry, semiconductor industry, petrochemical industry, chemical fiber industry, steel/medium frequency heating industry, automotive manufacturing industry, hospital systems, theaters, sports venues, etc.Major function
Automatic current limiting: Automatically limit the output to 100% within the rated capacity range. If the harmonic current on the load side is greater than the rated capacity of the machine, the machine will continue to output current to compensate for harmonics within the rated capacity, without overloading itself or exiting operation. Capable of withstanding the impact of instantaneous short circuit of the load and restarting after the short circuit is eliminated.
Parallel independent control: Connected to the power grid in parallel, there will be no power outage accidents caused by machine failures. Multiple active power filter parallel systems, if one machine exits operation due to a fault, the remaining machines can still work normally to achieve filtering function.
Independent control of three-phase current: Each phase current is independently controlled, single-phase injection current is not affected by three-phase current imbalance in the system, and the filtering ability of the neutral line is three times that of the phase line. The monitoring system has a fast and complete fault self check function, including various fault self checks such as under voltage or over voltage of the power supply, over voltage or over current of the busbar, fan fault, over temperature of the power device, blown input fuse, etc. All faults are sent out alarm signals through the LCD display screen and LED operation status lights, and the machine automatically takes corresponding operation protection system. The monitoring system can store 500 fault records in case of power supply or power outage, making it easy to analyze the cause and troubleshoot.Main technical parameters
