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 by various factors of network parameters, load change and environmental constraints relay, less than ideal filter 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. Low Pressure SZRY1 series surge protector for AC 50 or 60HZ 220v relay, voltage ≤380V the TN-S, TN-C, TN-CS, TT, IT and other power supply system. On the grid due to lightning or surge overvoltage protection. Surge protector, also called mine is an electronic security device for a variety of electronic equipment, instruments, communications line. When the electrical circuit or communication lines because of outside interference sudden peak current or voltage mini relay, surge protection can be turned shunt in a very short period of time, so as to avoid the surge of circuit damage other equipment. Role surge protector is fleeing the instantaneous power lines, the signal transmission line over-voltage limit within the device or system can withstand the voltage range, or the powerful lightning current into the ground, protective equipment or systems are protected against impact damage. Surge protectors vary according to the type and structure of different purposes, but it should contain at least one non-linear voltage limiting element. Basic components for the surge protector are: discharge gap, inflatable discharge, varistors, suppression diodes, and choke coils. 220v electromechanical relay _ _ Xi promise relay Lushan County, Henan study by Connaught Electrical and Mechanical Equipment Co., Henan Xi Connaught Electrical Equipment Co.
