Abstract: Provided in the present disclosure is a lightning induction-type solid-phase arc-extinguishing lightning protector. The lightning protector primarily including a lightning protector housing, an arc-extinguishing rotating disk, a conductive metal plate, an arc-striking rod, a fastening rod, an inductive coil, an arc-extinguishing cylinder, and a counter arm.

Abstract: Provided in the present disclosure is an arc compression-based arc-extinguishing lightning-protection gap device. The device comprises a lightning protector main body and an arc-striking electrode. The arc-striking electrode is fixedly mounted at one end of the main body. The other end of the main body is fixedly mounted, by means of a link fitting, to a crossarm or one end of an insulator string. The lightning protector main body is provided with an arc-extinguishing path consisting of several arc-extinguishing channels in a repeated Z-shaped arrangement. An arc-extinguishing tube at an inlet of a first arc-extinguishing channel of the arc-extinguishing path is connected to the arc-striking electrode via an arc-guiding rod, and an arc-extinguishing tube at an outlet of a last arc-extinguishing channel is connected to the link fitting.
