Detailed Product Description: | Active power filter connected to the grid in parallel independently controlled in parallel, will not happen because of mechanical failure caused the grid power outage. YW-APF multiple parallel active power filter system, if one out of operation due to malfunction, the remaining machines still work to achieve filtering. Independent control of three-phase current independent control of each phase current, single-phase injection current, three-phase current unbalance the system affect not mine harmonic control, the neutral filter capacity of three times the phase line. IP protection rating IP protection and lightning protection class IP20; lightning protection capability 20kA. Active Power Filter Harmonic basic major hazards: ? Increase load power facilities, reduce system power factor, reducing the effective capacity of power generation, transmission and electrical equipment and the efficiency of harmonic control program, resulting in waste equipment, waste and power line damage ; - causing reactive power compensation capacitor resonance and harmonic current amplification, resulting in a capacitor bank due to over-current or over-voltage is damaged or not in operation; · pulsating torque motor causes vibration, affect product quality and life of the motor; ? Since the eddy and skin effect, the motors, transformers, transmission lines and other produce additional power loss and overheating, waste of energy and accelerated aging of insulation; * harmonic voltage is proportional to its peak voltage of the electric field strength in the form of enhanced dielectric, reducing equipment life ; Zero sequence (3 multiple times) harmonic currents can cause neutral phase four-wire system overload and produce circulation in the delta-connected transformer windings, the winding current exceeds the rated value, even when serious accidents. · Harmonics will change the operating characteristics of protection relays harmonic control, malfunction protection facilities, such as automatic device operates on Protection disorder; · harmonic change the rate of change of change and peak voltage or current intermediate frequency harmonics governance, slow arc is extinguished, the impact of the circuit breaker breaking capacity; · make Metering especially induction meter produce measurement error; · interference from adjacent power electronics, industrial control equipment and communications equipment, affecting the normal operation of equipment.
