Product Desciption
The non-linear loads such as electric welding machines, laser welding machines, and large-capacity inductive loads (mainly based on electric motors) are used extensively in automotive workshops (press shop, welding shop, assembly shop, etc.), resulting in serious load currents in all transformers in the workshop. Harmonic currents are mainly 3, 5, 7, 9 and 11 times. The total voltage distortion rate of the 400V low voltage bus reaches more than 5%, and the total current distortion (THD) reaches 40%, resulting in 400V low voltage supply. The total harmonic distortion of the power distribution system is exceeding the standard and leads to serious harmonic power loss in the power equipment and transformer. At the same time, all load currents of the transformers in the workshop have severe reactive power requirements. The average power factor of some transformers is only about 0.6. There is a serious power loss problem and results in a serious shortage of the transformer output active capacity. Harmonic interference makes the car Fieldbus automated production system does not work.
Introduction
The active power filter (APF) is mainly composed of controller, isolation switch (circuit breaker), contactor, IGBT, driving circuit, protection system, fuse, connection reactor, DC capacitor, etc. The controller measures phase A, C reactive power(current), produces control signal, drives IGBT on/off and produces harmonic and reactive current same as system harmonic current but in opposite phase to filter system harmonic, reduce reactive power and keep system power factor approximately at 1.
Our APF equipment is module structure,there are two types Wall Mounted and cabient mounted.The Wall Mounted type is preferred to be used in equipment improvement which is very conveninet to install.
The Sanhe Modular Active Harmonic Filter series are suitable for applications of all types, providing harmonic mitigation, load balancing and step-less reactive power compensation for inductive and capacitor loads.
Advantages:
Optimize your harmonic filtering efficiency: the 3-Level Topology Design Approach
Active harmonic filters are based on power electronic technology, designed for mitigating harmonics injected by non-linear loads in power networks, generally installed in parallel to the polluting loads. The active filters analyze the line current harmonics drawn by the loads and generate a compensation current at the opposite phase angle, thereby "neutralizing" the harmonic currents.
Optimized harmonics filtering efficiency
Selection of every harmonic to the 50th order /Filter up to 50th harmonics simultaneously /Harmonic filtering levels [%] for each specific harmonic order can be pre-configured / Resonance protection by means of pre-configuring harmonic filtering levels for the potential resonance zones / Harmonic attenuation > 97%
Compact high performance
Ultra-compact, space economical / User-friendly, ease of commissioning / Parallel capability of modular AHF units with respect to network requirements / Available in rack, wall mounting designs and complete enclosure type
Enhanced Reliability Levels
Incorporates intelligent FFT calculation method:
Provides "real time sensing" of network impedance for progressive harmonics compensation to achieving system stability
Advanced control algorithm for resonance protection
In event of parallel resonance with load variations, the APF is designed to assess and "shut-down" to avoid equipment damage
Unique modular design.
Each module works independently both in wall and rack mount type, easy for logistics, installation and maintenance work.
Modular power ratings 35A/50A/60A/100A, and unlimited combination in parallel.
The maximum capacity per cabinet can be 600A, especially used in applications where space is at a premium.
