Input and output chokes Input Output Reactor Features: ◆ input end of the reactors for the inverter to suppress a surge voltage and surge current and protect the inverter and the governor gt250 relay, extend its life and prevent harmonic interference small relays, input reactor can be simply understood as: smoothing reactors, the scene selection voltage instability. ◆ Output reactors for the load side of the inverter, the motor current flows through the reactor. The purpose is to extend the output from long cable compensation capacitive charge reversal current selection from the inverter when the motor exceeds 100m (general cable). 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, 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 relay, Han Wei Harbin Electrical Equipment Co., Ltd. is dedicated to dynamic reactive power compensation and filtering equipment development and production of high-tech enterprises dzs233 relay, Wei Han Electric in cooperation with Harbin Institute of Technology, specialized in research and development of power active filter device for nearly a decade of history, development, production of active power filter APF system successfully used in automobiles, ports and other industries. smart relay | Luoyang New District Relays | Electromechanical provided by the Henan Connaught Xi Xi Connaught Electrical and Mechanical Equipment Co., Henan Xi Connaught Electrical Equipment Co.
