Abstract
A breaking device includes an interrupting section including interrupting units in which main interrupters, impedance circuits, and unit arresters are connected in parallel to each other, the main interrupters being connected in series, a resonant circuit section including a reactor, a capacitor, and a closing switch and connected in parallel to the interrupting section, and an all-point arrester connected in parallel to the interrupting section via the reactor. The clamping voltages of the unit arresters are equal among the interrupting units, and are in the range of 1.1 to 1.6 times the value obtained by dividing the clamping voltage of the all-point arrester by the number of the interrupting units connected in series in the interrupting section.
