Abstract

The invention discloses a zigzag synchronous compression arc extinguishing lightning protection device with arc extinguishing channels arranged in parallel. There is an arc extinguishing path composed of several sections of arc extinguishing channels arranged in parallel from top to bottom; an arc extinguishing tube (5) is placed in each section of arc extinguishing channel, wherein the arc extinguishing channel in the first section of arc extinguishing channel The head end of the tube is electrically connected to the arc striking electrode (3), the end of the arc extinguishing tube in the last section of the arc extinguishing channel is electrically connected to the connecting fitting (4), and the ends of the remaining arc extinguishing tubes are passed through a The three-way tube (6) and two T-shaped arc-guiding tubes (9) are sequentially connected; (6) Nested and connected together. 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 power transmission lines, in particular to a zigzag synchronous compression arc extinguishing lightning protection device with parallel arc extinguishing channels. 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 yet been controlled. But we can analyze the frequent accidents to find the law of lightning strikes and strengthen prevention. For example, poles and towers on high mountains or peaks, power transmission lines near ponds or reservoirs, poles that cross mountains or rivers and lakes, poles and towers installed on high grounding resistance, rock tower foundations, and transmission lines are all vulnerable to lightning damage Focus. [0003] Lightning strikes can bring different forms of damage and destruction to powe...
