Individually controlled parallel active power filter harmonic control plant connected to the grid in parallel, not because of mechanical failure caused power grid power outage. YW-APF multiple active power filter harmonic sail parallel system of governance, if one out of operation due to malfunction IF harmonic control, the remaining machines still work to achieve filtering. Independent control of three-phase current independent control of each phase current harmonic control, single-phase injection current, regardless of system phase current imbalance affect the neutral filtering capacity of triple-phase lines. IP protection rating IP protection and lightning protection class IP20; lightning protection capability 20kA. BDKJ-FC type II compensation means working conditions 1, altitude: not tall 1000m; 2, ambient temperature: -25 ~ + 55 ℃; 3, relative humidity: less than 85%; 4, runs the risk of explosion in places not allowed medium, surrounding medium should not contain corrosive and damage the insulation of gas and conductive media.
