Abstract: A first conductive member is fixed to a first fixed terminal having a longitudinal direction, and a second conductive member is fixed to a second fixed terminal having a longitudinal direction. The first fixed terminal and the second fixed terminal are fixed to a partition member. A first extension portion of the first conductive member includes a first opposed portion opposed to at least one of the first fixed terminal at a first fixed contact side of the partition member. The first opposed portion extends in the longitudinal direction of the first fixed terminal.

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: An electromagnetic relay includes a contactor including a fixed contact and a movable contact, and an electromagnet device for moving the movable contact. The electromagnet device includes a coil generating a first magnetic flux by energization, a tubular body including a permanent magnet generating a second magnetic flux in a direction identical to a direction of the first magnetic flux and having a hollow extending in a center axis direction, a movable element disposed in the hollow of the tubular body and reciprocating in the center axis direction, and a yoke forming a magnetic circuit passing together with the movable element and the tubular body. The magnetic circuit allows at least one of the first and second magnetic fluxes to pass through the magnetic circuit. The electromagnet device is configured to, when the coil is energized, move the movable contact to a first position by attracting the movable element with the first magnetic flux and the second magnetic flux. The electromagnet device is configured to, when energization of the coil is suspended, move the movable contact to a second position different from the first position. This electromagnetic relay is easily designed and reduces power consumption at a low cost.

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.
