Abstract: PROBLEM TO BE SOLVED: To shut off a small current in a short time without influencing the breaking operation of a large current to be required in the event of short- circuiting, etc., of a track by forming the second circuit consisting of a capacitor and reactor in series connection, and connecting this second circuit parallel with a vacuum valve. SOLUTION: The second circuit 5a consisting of a series connection of a capacitor 2a and reactor 3a is connected parallel with a vacuum valve 1 and a commutator circuit 5. When a turn-on comand S2 is given from a control circuit 11, a commutation switch 4 is closed, and a current starts flowing from a commutation capacitor 2. The combined impedance of the capacitor 2a and reactor 3a has a significant value, and the current from the capacitor 2 flows to the valve 1, wherein the current to the valve 1 will be such as directed oppositely to the load current on which a high-frequency discharge current is superposed.  Accordingly a small current can be shut off in a short time without influencing the breaking operation of a large current if the impedance of the second circuit 5a is made over several tens of times greater than the commutator circuit 5 while the capacitance of the circuit 5a is made below several percent of the circuit 5.
