摘要： A solar power generation system includes a string, an inverter a first shut-off device, and a second shut-off device. The string includes a plurality of solar cell module groups connected in series with each other. The first shut-off device cuts off a connection between the plurality of solar cell module groups connected to a first electric path connecting between the plurality of solar cell module groups in response to a first control signal from the inverter. The second shut-off device is connected to the first shut-off device in a two-way communicable manner by a communication system different from power line communication and cuts off a connection between the solar cell module groups connected to a second electric path connecting between the plurality of solar cell module groups in response to a second control signal output from the first shut-off device by a communication system different from power line communication.

摘要： An electromagnetic relay includes a first fixed terminal including a first fixed contact, a second fixed terminal including a second fixed contact, a movable contact piece including first and second contacts, a drive device including a coil, a case, and a magnet. The case includes an accommodation space accommodating the first fixed contact, the second fixed contact, and the movable contact piece, and a first arc extension space at least partially disposed between the coil and the magnet. The magnet is disposed so as to overlap with the coil in a third direction orthogonal to the moving direction and a longitudinal direction of the movable contact piece. The magnet configured to extend a first arc generated between the first fixed contact and the first movable contact and a second arc generated between the second fixed contact and the second movable contact in the longitudinal direction of the movable contact piece.

摘要： An electromagnetic relay includes a base, a first terminal, a fixing member, and a first adhesive. The base includes a first hole. The base is made of a thermosetting resin. The first terminal extends through the first hole. The fixing member is a separate body from the base. The fixing member has higher elasticity than the thermosetting resin. The fixing member fixes the first terminal to the base. The fixing member includes a first support wall and a first recess. The first support wall is disposed between an inner surface of the first hole and the first terminal. The first support wall extends upward along the first terminal. The first recess is disposed on an upper surface of the first support wall and faces the first terminal. The first adhesive is filled in the first recess. The first adhesive adheres the first terminal and the first support wall.

摘要： An electromagnetic relay includes a pair of fixed terminals including a fixed contact, a movable contact piece, a housing portion, and a magnet portion. The movable contact piece includes a movable contact disposed facing the fixed contact. The movable contact piece is movable in a first direction in which the movable contact contacts the fixed contact and a second direction in which the movable contact separates from the fixed contact. The housing portion includes a housing space housing the fixed contact and movable contact piece. The magnet portion includes a pair of magnets disposed around the housing portion so as to face each other in a longitudinal direction of the movable contact piece and extending in the second direction beyond the housing space. The magnet portion generates a magnetic flux flowing in a direction parallel to the longitudinal direction between the fixed contact and the movable contact.

摘要： A welding detection device includes a first circuit including a detection element, a first circuit power supply, and a second circuit. The first circuit is connected to a first line connecting a power supply and a main relay and a second line connecting a load and the main relay. The first circuit power supply supplies DC power to the first circuit. The first circuit detects welding in the main relay based on whether or not a current from the first circuit power supply has flowed to the detection element through the main relay when the main relay is controlled to be in an open state from a closed state. The second circuit cuts off the first circuit only when the voltage difference is present between the first line and the second line while the main relay is controlled to be in an open state from a closed state.

摘要： A housing includes a first space, a second space, a first hole, a second hole, and an arc extinguishing member. A fixed contact and a movable contact are arranged in the first space. The second space is partitioned from the first space. The first hole communicates the first space and the second space. The second hole communicates the second space with a space outside the second space. The arc extinguishing member releases an arc extinguishing gas into the first space. The second hole has a smaller opening area than the first hole.
