Abstract:
A direct current switch-off device comprises an on-state current branch circuit and a current commutating and breaking unit which are connected in parallel. The on-state current branch circuit has a mechanical switch (S) and a current transfer module which are connected in series. The current commutating and breaking unit comprises a bridge-type branch circuit and a current-breaking branch circuit. The current-breaking branch circuit and two bridge arms of the bridge-type branch circuit are connected in parallel. The current-breaking branch circuit comprises a nonlinear resistor (RI) and a valve group consisting of fully-controlled devices connected in series. The nonlinear resistor (RI) and the valve group are connected in parallel. Two ends of each fully-controlled device in the valve group are connected in parallel with a buffering and reclosing circuit.

Claim (Index 9):
The control method of the direct current switch-off device according to  claim 8 , characterized in that, in Step 302, whether the line failure is recovered is determined based on the following criteria:\n 1) the voltage on the faulty line is charged; 2) no voltage exists on two ends of the current-breaking branch circuit; 3) no voltage exists on two ends of the valve group consisting of fully-controlled devices connected in series in the current-breaking branch circuit; 4) no voltage exists on two ends of each fully-controlled device in the valve group consisting of fully-controlled devices connected in series in the current-breaking branch circuit; 5) no voltage exists on two ends of the capacitor in the buffering and reclosing circuit for each fully-controlled device in the valve group consisting of fully-controlled devices connected in series in the current-breaking branch circuit.
