Document Type and Number:
WIPO Patent Application WO/2018/040451
Kind Code:
A1
Abstract:
Disclosed in the present invention is an arc compression-based arc-extinguishing lightning-protection gap device. The device comprises a lightning-protection device 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 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 entrance of the first arc-extinguishing channel in the arc-extinguishing path is connected to the arc-striking electrode via an arc-guiding rod, and an arc-extinguishing tube at an exit of the last arc-extinguishing 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 invention has a simple structure, reasonable design, improved arc-extinguishing performance, and stable operation.
