APF high voltage power active filter device Product details: High APF active power filter device with the power electronic devices are widely used in various industries, non-linear loads increasing number of these non-linear loads generate harmonic currents endanger its surrounding equipment running led200us relay, causing the system voltage distortion serious, have serious adverse consequences. Conventional sources of these harmonic control using LC tuned filter (called passive filter), the operation indicators passive filter is restricted by various factors of network parameters, load change, environment, etc., reach the desired filtering effect . The twenty-first century, high-power electronic devices has been the rapid development, IGBT technology has become more sophisticated, it is the research and development of high-power active power filter APF device from the laboratory to the real market applications to create adequate conditions. Use the power active filtering device to eliminate harmonics is the most effective solution for a wide range of market demand, Han Wei Harbin Electrical Equipment Co., Ltd. is dedicated to dynamic reactive power compensation and filtering equipment development and production of high-tech enterprises, Wei Han Electric in cooperation with the Harbin Institute of Technology, a professional commitment to research and development of power active filter device for nearly a decade of history, development, APF active power filter system successfully used in the production of automobiles, ports and other industries. BDKJ-FC I type compensation device Product details: With the wide application of power electronics technology, higher harmonics generated by nonlinear loads of modern industrial and mining enterprises into the power system, causing the supply voltage waveform distortion, reduce power quality, capacitor banks can not into mini relay, accelerating damage electrical business equipment, the use of lower electricity rates, a waste of energy. Overview BDKJ-FC I type filter compensation device is mainly used in high pressure (6KV, 10KV, 27.5KV, 35KV) requires the harmonic control reactive power compensation system. Such as: ◆ electric arc furnace, intermediate frequency furnace rectifier inverter frequency devices ◆ ◆ ◆ Semiconductor convertors DC transmission equipment {mills, hoists, etc) ◆ ◆ rectifying electrolysis equipment and railway electrification. Device uses filter reactor, filter capacitor, discharge coil and an appropriate combination of a non-inductive resistor LC filter tuning circuit (single-tuned filter circuit, high-pass filter circuit), single-tuned harmonic filter circuit for grid feature to filter out possible harmonic entirely or almost entirely absorbed, the system voltage distortion is reduced; and for the fundamental frequency (50Hz), device can provide reactive power to the system to improve power factor, reactive power compensation to achieve results. After high-pass filter circuit above a certain frequency has a wide frequency range, to absorb a number of high-order harmonics at higher frequencies, to achieve the filtering effect, while reactive power compensation to reduce voltage distortion. Means in parallel with the load of the power system. In the actual design be designed according to the harmonic current composition, size and reactive power demand through accurate simulation and computing relays, making the harmonics filtering device to provide a low impedance path. Either single withered harmonic loop, high-pass filter circuit composed of a filter system for the system to filter out the harmonic components, while meeting the requirements for reactive power compensation. led200us relay, relay Xichuan County, Henan Xi promise offered by conventional electromechanical Connaught Electrical and Mechanical Equipment Co., Henan Xi Connaught Electrical Equipment Co.
