Filed: 1992-06-08
Abstract: PURPOSE:To simplify the structure of a DC circuit breaker system while keeping the effect reducing the shunt current to a cutoff resistor when the DC current is cut off by providing a backward current preventing reactor in series with the cutoff resistor. CONSTITUTION:When the thyristor switch 4 of a DC circuit breaker 2 is ignited, the energy stored in a capacitor 3 flows as the oscillating current through a main cutoff switch 6 by the resonance with a reactor 5.
