摘要： PURPOSE:To get rid of the dispersion of making actuation and enable an exciting rush current to be controlled effectively by arranging trigger electrodes near the main electrode of each phase and generating trigger discharge between the main electrode and the trigger electrodes when it is made to perform the making actuation with requested timing. CONSTITUTION:Trigger electrodes 102 are arranged near a main electrode 103 which is arranged in each phase of a circuit breaker 6. When it performs making actuation, trigger discharge is generated between the main electrode 103 and the trigger electrodes 102 so that the circuit breaker 6 is made electrically before it is made mechanically. The electrical input actuation like this has less dispersion than the mechanical making actuation so that the lag of the timing of the making actuation can be dissolved, and the circuit breaker 6 can be made with requested timing certainly.

SOLUTION: The DC cut-off system comprises a capacitor 1 that is connected in parallel to the circuit breaker 2, a reactor that is connected in series with the capacitor and limits the over current at the time of capacitor discharge, and a resistor 8 that is connected in parallel with the circuit breaker and consumes the energy by commuting DC current that is cut-off by the circuit breaker. By discharging the energy that is charged in the capacitor in the cut-off of the circuit breaker, and flowing the current of reverse direction with the flowing current to the circuit breaker, current zero point is made, and the current is cut-off by the circuit breaker in the vicinity of this current zero point. The inductance of the resistor 8 is made within the regulated value that is determined by the inductance of the two circuits of the capacitor, inductance of one circuit of the circuit breaker, cut-off current, capacitor charging voltage, capacitor capacity and the resistance value of the resistor.
