SURGE PROTECTIVE DEVICE FOR DIRECT LIGHTNING WITH PREVENTIVE FUNCTION AGAINST SECONDARY SHORT CIRCUIT FAIL

摘要

The present invention relates to a surge protective device for protecting direct lightning with a preventive function against a secondary short circuit accident. More specifically, the present invention relates to a surge protective device for protecting direct lightning with a preventive function against a secondary short circuit accident configured to prevent a secondary short circuit accident in advance which can be generated by coming into contact with blowout portions of a fuse again after the blowout of a fuse by transient voltage. The present invention comprises: a body part; a varistor which is combined with one point of the inside of the body part and includes a first electrode and a second electrode; the fuse whose one side of the bottom surface is combined with the first electrode; a fuse separation unit which comprises a through hole and is combined with the fuse through the through hole; a conductor whose one side is combined with the other side of the bottom surface of the fuse; a tension member whose one side is combined with the conductor and the other side is combined with the fuse separation unit. According to the present invention, the surge protective device can be provided such that after the blowout of a fuse according to direct lightening surge inflow, the separation between the blowout portions is securely done, and thus a secondary short circuit accident such as explosion and fire, etc can be prevented in advance.
