Claim 0:
1. A breaking device comprising:
an interrupting section including a plurality of interrupting units, in each of which a main interrupter, a voltage divider circuit, and a first arrester are connected in parallel to each other, a plurality of the main interrupters being connected in series;
a resonant circuit section including a reactor, a capacitor, and a closing switch, the resonant circuit section being connected in parallel to the interrupting section; and
a second arrester connected in parallel to the interrupting section via the reactor, wherein
clamping voltages of the first arresters are equal between the plurality of interrupting units, and are in a range of 1.1 to 1.6 times a value obtained by dividing a clamping voltage of the second arrester by the number of the interrupting units connected in series in the interrupting section.
