Active filter cabinet

Product Information

SWAPF active filter device series is connected to the power system in parallel mode, collects power system data in real time through an external sampling loop, analyzes the harmonic component data in the system through the internal core operation chip of the device, and controls IGBT high-frequency switching to output currents with the same amplitude and opposite direction as the harmonic current in the system to offset the harmonic current in the system, so as to achieve the purpose of controlling the harmonic current in the system.

Product Features

■ can filter out 2~50 harmonics, in this range of arbitrary choice of harmonic number, and adjust the filter output size, in order to achieve the best filtering effect

■ The full response time is 10ms, which can keep the system in an ideal state with THDI less than 5%,PF reaching 0.99, and three-phase imbalance less than or equal to 3%

■ Modular design, easy to maintain, easy to install, support rack-mounted installation, wall-mounted installation two installation methods

■ Independent air duct design, to ensure that the equipment has a good heat dissipation capacity, at the same time with a comprehensive temperature detection system, real-time detection of equipment temperature information

■ Reactive power compensation range (-1~1), capacitive inductive reactive power can be switched at any time to meet the reactive power compensation requirements of equipment with severe instantaneous reactive power changes such as stamping and electric welding.

Perfect protection function, 16 kinds of protection functions, to ensure the safety of equipment and system security

■ At the same time, it has the functions of harmonic control, reactive power compensation and three-phase imbalance control, and can flexibly adjust the functional priority according to different field requirements.
