ZAPF three-phase three-wire Shunt Active Power Filter (APF) Features: wide filter out the harmonic frequency range of 2 to 60 can filter out harmonics. In addition to the harmonic filter characteristics can build electrical and mechanical engineering, but also can filter out non-characteristic harmonic; Height: harmonic filtering rate. At rated power, harmonic current filtration rate can be up to 95%; fast: fast response. Harmonic compensating current complete response time of less than 10ms; Stable: single-phase dynamics can inject compensation currents, improve system unbalanced three-phase electrical engineering, automatic elimination of resonance, no resonance with the system generates fear, the protection of the safe operation of equipment and systems; total: from 25A to 300A single module cabinet, covering the active filter full range of products; supplement: both filtering and reactive power compensation (inductive or capacitive) capabilities, flexible set menu, you can select the maximum harmonic filtering mode, reactive power compensation mode or harmonic reactive compensation mode at the same time; you can set target power factor and output current; advanced technology: fully functional intelligent control systems; using the latest intelligent control unit 7-inch full-color touch screen display, friendly interface, simple operation; Display Interface It can display the voltage, current, load and equipment output harmonic harmonic waveforms, amplitude and spectrum and other parameters in real time; real-time fault recording and event recording; convenient: simple design selection, installation, operation and maintenance. , Without equipment capacity constraints, infinitely scalable parallel operation; reliable: You can set the output or the maximum output current limit is 100%, to ensure long-term stable operation of the device, no device overload fear. Having a system overvoltage, undervoltage protection; output over-current protection; overheating protection; control voltage undervoltage fault protection system. The basic principle of the active filter power filter, is the use of new power harmonic control equipment of modern power electronics and high-speed DSP devices are based on digital signal processing technology made. It is composed of two major parts of the circuit generated by the command current computing circuit and compensation current. Command current computing circuit current in the line real-time monitoring, and analog current signals into digital signals into high-speed digital signal processor (DSP) for signal processing electrical and mechanical engineering and maintenance, the harmonics of the fundamental separation of Henan Mechanical and Electrical Engineering, and pulse-width modulation (PWM) signal in the form of compensation current generation circuit to send the drive pulse, the drive IGBT or IPM power modules, generates harmonic currents equal in magnitude, opposite polarity compensation current into the power grid, the harmonic currents compensation or offset, the initiative to eliminate power harmonics.
