Пассивный фильтр гармоник

Passive Harmonic Filter We are looking for experienced Distributors and Agents worldwide! General Introduction: 1, ZRLC series of low-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 voltage1kVor below, with capacity ranging from dozens of kilovar to thousands of kilovar. Main performance 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, Well-developed protection for the following: over-current, quick break and so on.
