1. , a kind of multi-channel harmonic wave restraining device, it comprises current transformer (T), former side'"'"'s winding (W of this current transformer 1) coupled in series on electrical network bus (1), it is characterized in that one of this electrical network bus end and electrical network (2) join, the other end links to each other with harmonic source load (3);

  • Current transformer (T) has i secondary side'"'"'s winding (W 21, W 22... W 2i), the number of turn of these windings is identical, and physical dimension equates, each winding and corresponding inductance coil L iWith capacitor C iCoupled in series, inductance, the capacitances in series resonant tank of i passage of composition, and L 1=L 2=...=L iAnd C 1=C 2=...=C i, the inductance value L of each resonant tank iWith capacitance C iUnder operating frequency ω

    , satisfy series resonance condition ω

    L i=1/ ω
