Use
With the industrialization of the country level, the quality of the grid all walks of life become increasingly demanding. Also widely used industrial automation rectifiers, inverters, frequency furnace and automatic welding equipment generates a large number of harmonics, making the system voltage and current waveform distortion, resulting in deterioration of power quality, harmonic harm has become a major hazard grids. In order to filter out the harmonics on the power supply system, the use of harmonic reactive power compensation device filter is the best one of the methods.
The company applies advanced power electronics technology and intelligent control technology, scientific, economic and other effective means to not only solve the technical conditions in the harmonic compensation shunt capacitor switching problem, but also the actual situation and requirements of the user to suppress or governance harmonic, clean power supply network and improve the power factor. Therefore, the product is low harmonic content of the highest scientific and technological area of governance, most technologically advanced and reliable new products.
Structural performance:
An important part of this unit are: monitoring unit, SCR semiconductor modules, filter capacitor, filter reactors, circuit breakers, control systems and protection systems, cabinets and so on.
The capacity of the capacitor device is based on: fundamental frequency, the system needs reactive power compensation is determined; the LC circuit of the inductor value selection based on: frequency of the harmonic series resonance with the capacitor, the device in the form of the harmonic frequency is very low impedance (near zero), so that the majority of the harmonic current flow to the device, rather than the flow of power supply system. Improve the supply system harmonic voltage distortion. Both sets of devices installed in the parallel capacitor for rapid dynamic reactive power compensation. To meet the needs of rapidly changing loads.
The single-tuned filter compensator LC passive filter compensation, harmonic condition for the user-site design. A typical filter to filter harmonic compensation devices are generally divided into: 3 (150Hz), 5 second (250Hz), 7 second (350Hz), 11 second (550Hz), 13 second (650Hz) and so on.
