Product introduction:
Three-phase filter reactor is the wind power converter reactor. Wind reactor includes: du/dt fan side reactor, grid side reactor, incoming line reactor. Du /dt fan side reactor limiting voltage rise too fast, weak three-phase imbalance; Network side reactor is used together with filter capacitance and damping resistance to correct output waveform and reduce harmonic current. The inlet reactor suppresses the influence of LC filter capacitor current on the power grid and enhances the filtering effect.
