Abstract: This breaker device includes: a casing; an igniter disposed in the casing; a conductor including a separating portion disposed below the igniter; and a pusher located between the separating portion and the igniter and configured to move together with the separating portion from a first position to a second position located below the first position. The casing includes: a first casing made of a metal, including a first fixing portion, and configured to house the igniter and the pusher located at the first position; and a second casing made of a metal, including a second fixing portion, and configured to house the pusher that has moved to the second position and the separating portion that has moved downward together with the pusher. The first fixing portion and the second fixing portion overlap each other, come into contact with each other, and are fixed to each other.

Abstract: An interrupter system includes a first coil and an interrupter electrically connected to the first coil. The interrupter includes: a first terminal; a second terminal electrically connected to the first terminal; a third terminal electrically separated from the first terminal and the second terminal; a heat generating element electrically connected to the third terminal; and an explosive configured to be ignited by the heat generating element to produce a gas for interrupting an electrical connection between the first terminal and the second terminal. The first coil is electrically connected to the heat generating element via the third terminal. Moreover, the first coil is configured to, when an abnormal current flows between the first terminal and the second terminal, generate an electric power for igniting the explosive from the abnormal current.

Abstract: This breaker device includes: a casing; an igniter configured to generate gas; a pusher located inside the casing and positioned below the igniter; a conductor including a separating portion positioned below the pusher; and an elastic member disposed to be positioned between the casing and the pusher to press the outer side surface of the pusher. In the state where the pusher is stationary after the pusher moves the separating portion downward under the pressure of the gas generated by the igniter, the pusher is located at a level below the elastic member, and the inner surface of the elastic member overlaps the pusher as viewed from above.

Abstract: A control system is designed to control an interrupter. The interrupter is started by a startup current to interrupt a main electric circuit. The startup current flows through an auxiliary electric circuit and has a current valve equal to or greater than a predetermined value. The control system includes a driving unit and a driven unit. The driving unit includes an intermediate electrical path to be connected to the main electric circuit. The driven unit is to be connected to the auxiliary electric circuit. When an abnormal current having a current value equal to or greater than a prescribed value flows through the intermediate electrical path, the driving unit uses, as a drive source for driving the driven unit, the abnormal current flowing through the intermediate electrical path. The driven unit supplies the auxiliary electric circuit with the startup current by being driven by the driving unit.
