Abstract

The invention discloses a meandering synchronous compression arc extinguishing and lightning protection device, which comprises a main body of a lightning protection device and an arc striking electrode. The outer surface of the main body of the lightning protection device is provided with a skirt; The arc extinguishing path II composed of circular arrangement; the head end of the first arc extinguishing tube II in the skirt is electrically connected with the end of the arc extinguishing tube I in the main body of the lightning arrester above the skirt and closest to the skirt, and finally The end of one arc extinguishing tube II is electrically connected to the head end of arc extinguishing tube I in the main body of the lightning arrester below the skirt and closest to the skirt; the ends of two adjacent arc extinguishing tubes II are directly contacted or connected. Connected by connecting piece II; there is an air flow outlet channel II at the junction of two adjacent arc extinguishing tubes II, and the air flow outlet channel II extends to the outer surface of the skirt, that is, the outer surface of the skirt is provided with air flow Outlet II. The invention has the advantages of simple structure, reasonable design, stronger arc extinguishing ability and stable and reliable operation.

Description

technical field [0001] The invention relates to a lightning protection device for a power transmission line, in particular to a meandering synchronous compression arc extinguishing lightning protection device. Background technique [0002] Lightning is an important factor affecting the safety of transmission lines. It has long occupied the first place in line fault tripping. It is a natural process of atmospheric activity and has not been controlled so far. However, we can analyze the frequent accidents to find the law of lightning strikes and strengthen prevention. For example, towers on high mountains or peaks, transmission lines near ponds or reservoirs, towers crossing mountains or rivers and lakes, and towers installed on high grounding resistance, rocky tower foundations and transmission lines are all vulnerable to lightning damage. focus. [0003] Lightning strikes will bring different forms of damage and damage to power facilities. Thundercloud discharge will cause...
