Abstract

See full text

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. A three-way tube is provided at a joint of two adjacent arc-extinguishing channels; two ends of the three-way tube are each provided with one arc-guiding electrode; and the arc-guiding electrode has one end extending into the three-way tube and the other end connected to a nearby arc-extinguishing tube via direct contact or a wire. The present disclosure has the advantages of simple structure, reasonable design, improved arc-extinguishing performance, and stable operation.
