Active harmonic filter module
The active power filter (APF) is connected into the power system in parallel, through the external sampling circuit, the power system data is collected in real time, and the harmonic component data in the system is analyzed by the core operation chip of the equipment, and control IGBT high frequency switch, output and the system harmonic current, current amplitude is equal to the opposite direction of the current, the system harmonic current to cancel, in order to achieve the control system harmonic current
Priduct advantage
It has the functions of harmonic control, reactive power compensation and three-phase imbalance control. It can flexibly adjust the function priority according to the different needs of the site;
Ø Independent air duct design, ensure that the equipment has good heat dissipation capacity, while a comprehensive temperature detection system, real-time detection of equipment temperature information;
Ø Modular design, easy to maintain, easy to install, support the rack-mounted installation, wallmounted installation of the two types of installation;
Ø Reactive Power Compensation Range:(-1~1);the capacitive inductive reactive power can be switched at any time to meet the reactive power compensation needs of the equipment such as stamping, welding, etc.
Ø It can filter out 2~50 harmonics, select any harmonic number in this range, and adjust the filter output size to achieve the best filtering effect;
Ø With full response time of 10ms, the system can keep the ideal state of THDI less than 5%,PF 0.99, and three-phase unbalance less than or equal to 3%.
Ø Perfect protection functions, 16 kinds of protection functions, to ensure the safety of equipment and system security.
