Zusammenfassung:The utility model provides a three-phase synchronous drop-out device during the drop-out of a one-phase fuse, and belongs to the technical field of power-off protection equipment in a power system. According to the technical scheme of the utility model, the device is configured to fuse three-phase circuits synchronously upon the drop-out of a one-phase fuse. By means of the device, when the fuse of a circuit of one phase drops out, the fuses of the circuits of three phases are enabled to drop out synchronously. The device comprises drop-out fuses arranged in circuits of three phases, wherein each circuit is provided with one drop-out fuse respectively. Each drop-out fuse is provided with a live-line display induced magnetic bottle. The loop of each live-line display induced magnetic bottle is provided with a coil. Each coil is internally and movably provided with an iron core. Each iron core is provided with two insulated linkage lines, wherein one ends of the two insulated linkage lines are connected with th
