    • A capacitor and an inductance are connected in parallel with an interruptor disposed in a d-c circuit before the interruptor is mechanically opened. An oscillating current i.sub.o occurs in a circuit composed of the interruptor, the capacitor having a predetermined capacitance and the inductance having a predetermined amount of inductance when the interruptor is mechanically opened. The amplitude of the oscillating current i.sub.o is gradually increased and is superposed on a d-c current I. The interruptor breaks itself when the sum of the d-c current I and the oscillating current i.sub.o across the interruptor reaches zero.
    • 在断开器被机械打开之前,电容器和电感与设置在d-c电路中的中断器并联连接。 在由断路器组成的电路中产生振荡电流io,电容器具有预定的电容,并且当断路器被机械地打开时,电感具有预定的电感量。 振荡电流io的幅度逐渐增大并叠加在d-c电流I上。当d-c电流I和跨过中断器的振荡电流io的和达到零时,断路器自身断开。
