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.

Abstract: The contact apparatus includes a fixed contact, a movable contact, and an arc extinguishing member. The movable contact is movable between a closed position where the movable contact is in contact with the fixed contact and an open position where the movable contact is separate from the fixed contact. The arc extinguishing member is for discharging an arc extinguishing gas offering a capacity for extinguishment of an arc, into a space containing the fixed contact and the movable contact.

Abstract: An interrupter includes a gas producer, an actuator pin, and an electrical conductor. The electrical conductor includes a first terminal portion, a first separable portion, a second terminal portion, and a second separable portion. The second separable portion is electrically connected to the first separable portion in parallel. A first timing when the first separable portion starts to be cut off from the first terminal portion is earlier than a second timing when the second separable portion starts to be cut off from the second terminal portion.

Abstract: A contact device includes a fixed terminal, a moving contactor, a moving yoke, and a bus bar. The moving contactor moves from a closed position where a moving contact is in contact with a fixed contact to an open position where the moving contact is out of contact with the fixed contact, and vice versa. The moving yoke moves, as the moving contactor moves, in a direction of movement of the moving contactor. The bus bar generates, when energized, a magnetic field having a direction aligned with the direction of movement of the moving contactor. The bus bar is arranged, with respect to the moving yoke when the moving contactor is currently located at the closed position, in a direction in which the moving contactor moves from the open position toward the closed position.

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: A bus bar of a contact device includes at least one electric path piece selected from a reverse and a forward electric path piece extending along a direction of current flowing through a moving contactor. The moving contactor is positioned between the reverse electric path piece and a fixed contact in moving directions of the moving contactor with the moving contactor positioned in the closed position. The reverse electric path piece allows current to flow therethrough in an opposite direction from current flowing through the moving contactor. The forward electric path piece is positioned on a same side as the fixed contact relative to the moving contactor in the moving directions of the moving contactor with the moving contactor positioned in the closed position. The forward electric path piece allows current to flow therethrough in a same direction as current flowing through the moving contactor.

Abstract: The contact device switches between a closed state where a movable contact is in contact with the fixed contact and an open state where the movable contact is apart from the fixed contact as the movable element moves. The bus bar is electrically connected to the fixed contact. A magnetic field generated by a current flowing through the bus bar when the contact device is in the closed state applies, to the movable element, force oriented such that the movable element is maintained at a location where the contact device is in the closed state. In such a positional relationship, the bus bar and the electromagnetic device are disposed.
