Oberwellenfilter

Harmonic Filter We are looking for experienced Distributors and Agents worldwide! General introduction: The equipment is used for different voltage class (3 35kv), with capacity ranging from hundreds of kilovar to several ten thousand kilovar, which can be found widely used among metallurgy, mining, oil, chemistry, machine-making, light industry, and municipal construction as well. Working principle: 1, ZRFC series of high-voltage passive filtering device is composed of multiple LC filtering braches encompassing filtering capacitor, filtering reactor, free-inductance resistor,which is connected in parallel to the power network with nonlinear load. 2, All the filtering branches designs take key points into account including: the components and amount of harmonic and Var compensation. For the harmonic, each filtering branch works the same as the low-resistance route way, making most relevant harmonic flow into this branch. In this way, the filtering gets done and also the voltage common point and current distortion get less. Besides this, the device can supply the power system with capacitive Var power to enhance power factor of the power system. 3, The equipment can be used for different voltage class (3 35kV), with capacity ranging from hundreds of kilovar to several ten thousand kilovar. Main Characteristics: 1, Professional simulation calculation, design, check, to optimize the device design 2, Tailor-made filtering reactor and good-quality filtering capacitor adopted 3, Functions to keep the harmonic from increasing, and avoid resonance with power system available 4, Simple structure, low investment, reliable operation performance and low-cost maintenance 5, High-quality filtering capacitor featuring high reliability, low power-consumption, low temperature while working 6, Perfect capacitor protection is as follows: high-voltage step-by-step ejecting fuse adopted to carry out short-circuit protection for single capacitor, neutral-point imbalance current protection, open delta voltage protection, and voltage differential protection adopted for capacitor banks imbalance protection for capacitor banks 7, Well-developed protection for the following: over-current, over-voltage, low-voltage, low cycle and so on Main technical parameters: _______________________________________________________________ Rated voltage 3 35kV Rated frequency 50Hz/60Hz Harmonic filtering 5th, 7th, 11th, 13th or above(based on contents of harmonic) Filtering efficiency More than 70% of harmonic eliminated Power factor>0.90 (depends on customer'srequirment) Var compensationPower factor extends 0.92 Structure styleCabinet,(half) opening Duty class continuous Altitude above sea levelBelow 1000m Note: Any special conditions, please consult us.
