1. ;

  • a kind of thyristor electronic board for failure current limiter;

    comprise and get the energy loop;

    the power source conversion loop;

    thyristor forward voltage and thyristor electronic board TE power supply monitoring loop;

    trigger the loop;

    the forward excess voltage protection;

    the logical circuit road;

    repayment signal circuit and opto-electronic conversion loop etc.;

    it is characterized in that the quick by-pass switch K of fault current limiter adopts thyristor;

    thyristor electronic board TE realizes that thyristor triggers and on-line monitoring;

    fault current limiter thyristor valve trigger and on-line monitoring are in the bottom of control system;

    thyristor electronic board TE is installed on the valve body;

    a part that belongs to the thyristor level;

    thyristor electronic board TE receives light triggering and the monitoring pulse code that valve base electronic device VBE sends;

    through decoding after the thyristor electronic board TE opto-electronic conversion;

    thyristor electronic board TE is according to valve base electronic device VBE command triggers thyristor and with the thyristor state;

    thyristor electronic board TE self power supply status;

    the thyristor protection actuating signal is encoded, through sending to valve base electronic device VBE after the electric light conversion.
