Low-voltage active power filter APF Technical Parameters: l Electrical characteristics: Rated voltage: 0.4,0.55,0.69,1KV Power frequency: 50Hz electrical wiring: three-phase three-wire or three-phase four-wire maximum harmonic current: 50A, 100A, 150A, 200A, 250A, 300A (single) Current sampling methods: the total load current transformer secondary side sampling harmonic control, sampling the signal cable 2.5mm2l performance indicators: voltage fluctuation range: ± 10% harmonic range: 2 times ~ 50th harmonic (or filtered user-specified load characteristic harmonic) filtering effect:> 90% of the operating modes: filtering, compensation, compensation filter + three selectable operating modes Response time: <10ms active: <1% Protection features: over voltage, over current, current limiting, temperature, IGBT and other protection l control features: Nominal switching frequency: Average 10KHZ control algorithms: frequency-domain filter controller with adaptive compensation algorithm vector capabilities: dual closed-loop tracking and low voltage harmonic control cabinet, using high-speed large-capacity DSP Display: large-screen, high-definition, Chinese menu display color touch screen l Structure: Protection class: IP 20, IP30 color: a user-specified (standard color: gray microcomputer) Cooling Type: forced air cooling overall structure: Cabinet-type rectifier harmonic control, can be used together with the associated switchgear cabinet installation can also be placed on-line mode Independent: Cable; up and down the line; bus connection active power filters in parallel and independently controlled coupling into the grid, the grid will not happen because of mechanical failure caused the power outage. YW-APF multiple parallel active power filter harmonic control system charger, 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, 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.
