1. Overview

TH-APF Series Active Power Filter Cabinet adopts modular standard design, of which modules of different capacity can be freely matched for easy installation and maintenance. The equipment adopts the current advanced analog logic method to detect the current waveform generated by the nonlinear load in the power grid, and to dynamically generate the reverse harmonic current to compensate for the harmonic current of the load. It can effectively eliminate 2 to 50 times of grid harmonics, and can select specific subharmonic compensation.

TH-APF Series Active Power Filter Cabinet has the advantages of fast response speed, wide filtering range, high filtering efficiency, no impact from system parameters, perfect protection function and small size, etc. It is an ideal filtering product to improve the quality of power consumption, reduce the loss of the power grid, and increase the efficiency of power supply utilization and load carrying capacity.

This active filtering device is widely used in commercial construction, metallurgy and mining, automobile manufacturing, photovoltaic, petrochemical, machinery, light industry, municipal, military, electronics, non-ferrous, shipping industries and other industries.

2. Performance Features

◆ Improve the power supply security and reliability of power grid

It can filter out harmonics, reduce line and equipment heating, reduce equipment failure, misoperation, and inaccuracy of measuring instruments, communication interference and other safety hazards caused by harmonic pollution, in order to provide guarantee for the orderly conduct of production and life.

◆ Extremely low loss and low noise

The equipment adopts the fifth-generation IGBT which can greatly improve the switching frequency; when it is working at full load, the active loss is less than or equal to 2.5%, which is lower than the industry mainstream index 3% to 4%. When the whole machine is working at full load, the noise is less than or equal to 60dB.

◆ Real-time detection for dynamic compensation

It can detect harmonic current in real time, automatically track load harmonic changes, with high controllability and fast response.

◆ Safe and reliable performance

Filtering performance is not affected by system impedance. Resonance prediction management can effectively prevent capacitor capacity decay, avoiding resonance risk.

◆ Easy maintenance

It features standard modular design, plug and play, free combination, unlimited expansion.
