Abstract
Provided is a fuse-preposed lightning protector comprising an insulated fixing seat, at least two fuses, surge protection devices, and busbar devices, wherein the number of the surge protection devices and the number of the busbar devices are same as that of the fuses. The fuses, the surge protection devices, and the busbar devices are disposed on the insulated fixing seat. The output end of each fuse is electrically connected with a corresponding surge protection device. The output end of each surge protection device is electrically connected with a busbar device. According to the fuse-preposed lightning protector, space occupied by the surge protection devices is decreased; and the number of wires through which the fuses and the surge protection devices are connected is not increased such that wire inductance value can be reduced, response speed is increased, and residual voltage is reduced. The fuses disposed on the input ends of the surge protection devices are electrically disconnected with wires when a continuous short circuit fault occurs to the surge protection devices. Thus, fire hazard caused by aging of the surge protection devices or continuous short circuit fault can be prevented.
